Easy Vortec 350 Combo (High Torque 400+ ft lbs)

[@cecilsabourin9462]

Picked up a ,97 Vortec motor to drop in myb,92 Silverado.This is invaluable info and thanks for building this motor for all us guys who don,t run their trucks at 6000 rpm at every chance. Most of my driving is at 1900 rpm,s ( 65 mph) on the highway with my 700 r overdrive trans.+ 350 TBI motor ( soon to be replaced with the ,97 motor . I live in a small ,country village ,so highway distantce travelling is normal ( fuel economy ) .

[@dakotadale567]

Very similar to what I just put together for my K20. Wanted the torque for the bigger tires and wheeling at low rpm. It will tow a little too. Great combo

[@ahoneyman]

Built one very similar to this for an 80's Caprice. What a fantastic highway cruiser. It pulled the super tall gears in the rear end like nothing.

[@chehystpewpur4754]

great motors. honestly the last great chevy motor. i have one in an s10 blazer lunati roller torque cam kept the fuel injection long tube headers till next season. 4 speed auto and 3.42 gears with fairly small tires. 35mpg at city speeds up to 55-60mph back roads is best mileage. highway is about 28-30 mpg at 70-75 its not stupendous but for a vehicle that can run the 1/4 mile in the 12 sec range and a timeless box chevy body thats not a bad commuter car.

[@richcollins513]

I bought a Pro Flo 4 XT for my 350 Vortec and cant wait to install it. Thanks for the video, I watch every last L31 Vortec video I can find, make more please :)

[@zAvAvAz]

Always bowl port! Use ultra magnum chromoly roller rockers they have a warranty! A 3.625" Nodular crank would be awesome. 1.3625" Mahle pistons (with 9.025" deck). 5.85" rods. 10 to 1+ static compression. XR276HR10 cam. Ported AFR enforcer 195cc heads. Performer EPS. Vizard modified and tuned holley. 1.614 to 1 rod ratio= decent for cylinder wear and longevity. A 6.125" rod for 1.69 to 1 rod ratio would be even better. its just awesome.

[@HSTvids357]

Watching again a year later thinking about how mine will do. 10:1 old style 350, was a short block that sat in a garage since the late 80's, and it reflects that. TRW flat tops, stock everything else, and a Crane Energizer, .450 lift/218 @.050 on a 106 lsa. I just tore down, cleaned up, replaced rings and bearings, engine had never been ran. Threw a set of vortecs and similar intake to this on it, with summit "ls6" springs and comp 787 retainers. I had around .530 to the seat so I didn't use the offset keepers. Think a 1.6 exhaust valve and blend would help a bunch with the single pattern cam, but it should still make similar power to this, I believe. Sounds good on the stand, now to get the truck on the road.

[@cuttersperformance]

Probably abit more power than this build! Hopefully you get it in soon and enjoy it

[@scottk5209]

That’s the 274H06 cam. Nice sounding lumpy idle with that narrow 106 LSA, but surprisingly torquey just off idle, even works with low comp smog 350’s

[@HSTvids357]

@Scott K it worked great. I actually stepped up to an isky 280 mega, but just because I didn't lose any of the bottom end, and felt I had some room to grow on top. Similar concept, just more duration and lift, and a 108 lsa vs 106. Something about the tight lsa single pattern cams seems to work well mid range. I kept all the lifters labeled by bore and wrapped the cam up, because I will surely find another use for it. Great for a mild engine for sure

[@shredfest30]

Cool info here. I am putting my L31 back together with a totally stock bottom end, and I've mimmicked your bowl work and unshrouding from your other videos with some fresh Manley undercut stem valves, beehive springs, XR276HR cam, roller rockers, GMPP ZZ dual plane intake with a 650 holley. I was hoping to see around 360-370hp at 5800 with that strong torque band of this motor. I really appreciate watching and learning from all your videos man... Keep them coming! Cheers

[@jjmccloud]

@@jayree379 add about 45TQ and 30HP to this and you've got it lol

[@chehystpewpur4754]

@@jjmccloud honestly maybe a little more torque down lower. these heads love gulping air down at low rpms. yes they stall at higher rpms but they dont stop flowing they just dont get gains from flowing at that point. they still flow more air just nothing else is left to be had without affecting the torque down low. with added displacement and flowing on the heads and a proper torque cam for the engine it would make tons more torque and a bit more hp while still being super streetable unlike all these cammed out screamers with high stall convertors. youd end up with big block torque in small block package. but you must use splayed caps from a 2 bolt block. the vortec bottom end is weak for small block builds. 2 bolt is mainly what youll find 4 bolt is a no no. weaker block and less meat for the mains too. 2 bolt is strongest block and splayed caps are stronger than a proper 4 bolt. with a very mild setup you could net 500-600 ft lbs of torque under 3k rpms. and still have 400-500hp no questions asked on the top end. a motor that just pulls rips off idle and just keeps getting better.

[@jacobnorth8642]

​@@chehystpewpur4754i wouldn't call a 4 bolt "weak* sure if you want to spend on the machine work to take a 2 bolt to splayed, great. Or just buy an aftermarket block that is already set up with splayed and thick decks... or build your 2/4 bolt stocker and have fun, good reliability too, except for extreme engines

[@yurimodin7333]

wouldn't vortec heads have a hard time feeding a 383? I could be wrong tho.

[@cuttersperformance]

It really depends on how high you want to rev it. Basically it comes down to your cam selection, as a well setup vortec head can work great on a 383 that doesn't see much past 5500 RPM

[@permagrin8742]

Low buck power is cool. That motor would also be a fun street build in a small or full sized half ton 2wd pickup with proper gearing and 100 shot of nitrous. Especially with the extra massaging to get to the 330hp level. Won't be setting records but still would be a fun budget street setup.

I don't think you'll come up a little short of your hp goals. Even the Ramjet only made 330hp IIRC. Should hit 400+ torque though. I have that same cam with some 1.6 roller rockers and marine intake on my truck. Feels like stock, but just more of it everywhere.

Been looking at a Summit cam for a truck 350 im planning to put vortecs on, part #sum-1102. Has .421/.444 lift and 204/214 duration, looking for lots of low end torque. Is there a possible valve spring upgrade that doesnt require different keepers and retainers that would work with this cam? Is it actually a proper cam choice for stump-pulling torque? Its my first engine build and im hoping i did my research correctly. Love your videos! Thanks

A good set of stock vortec springs would work with that cam. Don't use a high milage set though as they lose seat pressure over time

replace all of intake rocker arms with 1.6 ratio arms. it will give a little more lift and deration and still be within the safe zone of the stock springs and retainers.

QUESTION: I'm in the middle of getting a 1997 K1500 Z71 EXT-CAB 5.7L 4x4 ready to use for work & play. Because it will be used for work M-F I want to retain decent MPG & drivability but want a little more power. This cam seems to really fit what I am looking for. My question is what kind of HP & TQ number would you expect when putting this cam in my mostly stock truck along with the following upgrades: * 1" intake spacer. * K&N intake kit with pipe, filter housing & filter. * Upgraded spider injectors with valves at the end of the injector lines. * Accel coil, plug wires & platinum plugs. * Flow Master 2.5" catback system. NEAR FUTURE UPGRADES: *Complete exhaust, shorty headers & mid-pipe with high flow cats. * Dyno ECU tune (of course, this will be the very last thing i do to it). I know the engine that you put the cam in, in this video probably breaths better than mine and has a more performance minded fuel injection system but I'm hoping to get 80% of the extra HP & TQ that you did. Am I living in fantasy land or is that a realistic expectation? (I know that you don't have a crystal ball but your best guess is most certainly better than mine. Don't worry about me trying to hold you to what you said, if i don't get the performance that I'm shooting for. I appreciate you taking the time to read this)

[@cuttersperformance]

Youll have some parasitic loses over this engine but this cam will certainly help with power. Its a mild cam and works well with basically a stock engine. With a good set of headers(go long tubes if you can), a good tune you should notice some decent proformance improvements without a loss in mpg.

The factory fuel injection and cam are a limiting factor on these engines, but they respond well to a set of headers and a good flowing exhaust system if you're just trying to pick up abit of power.

How Many CFM carburator can be a good option for this combinación?

[@cuttersperformance]

600 CFM would be a good choice

[@crudeprelude]

Running a 600cfm Holley and my truck STINKS! can’t figure out what’s going on with it. Poor gas mileage and terrible smell, can’t even start it and run for a few seconds without it stinking up the whole garage. Then I smell like it the rest of the day. Thinking about drilling the butterflies.

How could i put this in my 98 c1500 ?? Chevy saying i can only run 315hp with stock fuel injection and flash computer, i would love atleast 400-450 hp.

[@permagrin8742]

How high a compression ratio for Vortec heads on E85? It’s actually becoming available from the pump near me. Always enjoyed the snappy response from a higher compression engine. Not even for max HP just the torque and response since it’s just more of a pleasant engine to drive on the street.

[@cuzz63]

E85 exclusively you can run over 15 :1 compression. I would stick to 12:1 or something around that.

[@permagrin8742]

Would this be a good replacement motor for a 1989 TbI motor ? I want to use the oem stock TbI and ecm ? ! have the complete stock 1989 TBi set up in the hot rod in my picture. I realize that I would have to use a Vortec TBI intake or performer style intake with a TBI adapter. I have a complete 1999 vortech donor high millage engine to use. . I am interested more in economy gas millage / relability then high horse power performance.

[@cuttersperformance]

Yeah it would work great overall but like you said you would need a intake or adaptor and a new tune (prom) would be needed to run properly. I have been playing with and porting a set of tbi heads, not vortec flow but im getting some good gains onnthw flow bench. I would like to use them on a future build

[@rmmm6725]

Long tube headers, heads, intake, new chip, and cam. Make sure you match up the intake, headers, and cam so you have proper lift or it’s all for not. Jegs has some really good people to help walk you through it. If you take out the engine it’s a perfect time to go all out and replace tie rods, ball joints, control arms, shocks, and scrub the frame down then rust proof. Sounds like a lot but it’s all needed. Adding horse power without solid components is dumb, also good time to rebuild the transmission

New springs and machining aren’t currently in the budget, but do I really need them?

Unfortunately I don't think i would for two reason. 1) its going to be close for retainer to seal clearance 2) your most likely going to float the stock springs with that cam

There isn't anyway this engine has enough vacuum for power brakes to be working properly. In fact 270 is about all you can run on duration for the street with an automatic transmission. I can say at least in my experience . and if what you said in this video is true can explain this. Just asking.

[@cuttersperformance]

This is like a stage 1 cam and very mild. It pulls lots of engine vacuum. It worked very well with power brakes and the fuel injection I put on it. Expect 16 to 18 inch at idle with this cam Duration is just one part of the puzzle, the stock L31 cam has 263 deg of intake Duration and idles smooth

Two of the lifters don't seem to be holding very well and I've heard of other people also having trouble with brand new hyd. flat tappet lifters.
