Richard, I see you do SO MANY FLAT TAPPET HYDRAULIC CAM SWAPS, but with all these failures happening these days, could you PLEASE do a video on the failures in general, if and how many failures you’ve had, HOW you do your break up and, and what products you’ve been using that have not failed you! PLEASE!! There’s a HUGE group of us following you, and this is critical info for us hobby/ garage guys right now!!! Thank you! Love ALL YOUR VIDS!!!! You’re a treasure chest of useful info to all of us!!!!!

I would like to know if you had to switch out the push rods. I have a 97 or 99 350 vortec that I am tinkering with in the garage. Orginally was gonna go all out and 383 it, but instead taking the cheaper route with just upgrading cam. Saw this vid and considered doing the cheap route.

[@chrisedwards7485]

I have a 76 SBC 350 and want to add vortec heads. I found online that the 98-02 vortec heads have a different bolt angle. “The regular 350 head utilizes a 90 degree intake bolt angle while the Vortec makes do with a 72 degree bolt angle.”

[@theguy9234]

That's right. You will have to get a vortec intake.

When I tryed to put this Xm270h cam with those lifter and upgraded springs in my 1998 vortec motor and the timing chain gear for the 1998 cam gear has a different bolt pattern so what should I do now

[@darinr9424]

if u used a roller cam get a chain for a hyd roller cam. if its not a roller cam use a standard chain. if your engine uses the cam stop plate to retain the camshaf it takes the cam chain with the smaller bolt pattern.

Only issue is I have this combo. You have to have additional machine work done to vortec heads to run that camshaft. If you use oem style. The rocker arms won’t clear the pedestal. Comp cams sells a tool to cut them down. And I heard they make or are making a spring that will allow the clearance needed.

[@Unreliable_cars]

the springs in the video are the ones that allow the clearance

[@Flippa001]

Your website recommends 26981-16 / 981-16 valve springs. Did this change after the video was made? Thanks

What is the part number for the intake manifold?

What was the compression ratio with the vortecs?

[@miscellaneousyt5605]

Can you run 87 octane with this combo

[@SOU6900]

How about a similar video on the 454?

[@DonziGT230]

From my understanding, putting Votrec heads on a non-Vortec motor yields a much higher compression than a Vortec motor has, possibly too high for a mild build and pump gas.

[@greens1087]

So as compression does play a roll the cam shaft is where you want to pay attention because that’s where dynamic compression comes to play.. you could have a 11:1 static compression but if your dynamic compression comes out to a 8:1-8:5 you can run pump gas.

[@Bige4u]

My left ear enjoyed this video so much..... of course the mic is on his left shoulder. o_0

[@Pissrust69]

Heres a super dirt cheap power combo im thinking of doing to my daily driver (77 impala) its got the 350 and its all stock at the moment with 76cc heads etc. i can get vortec heads from my local junkyard for $50 and a quadrajet spreadbore dual plane intake off amazon for 220 and i found a set of headers on kijiji for 150. Gonna slap it all together this summer when im able to drive my camaro for a bit. Should be around 300-320hp for $500-$600 all said and done including the cost of gaskets etc. i’d be reusing my qjet and stock cam, accessories, distributor etc so only around 500-600 to almost double the power. Not bad at all.

[@kashbrown4649]

I thought the stock Vortec heads would only allow for ~.460 lift unless you grind the valve guides?

[@Compcams1976]

With the spring kit mentioned in the video (or the 26918-16 spring, 787-16 retainer, and 648-16 lock) you can get up to about .520 lift before needing to do any head work!

[@gregoryfoster8583]

@comp cam I have a vortec out of a 2000 Cadillac Escalade what’s need to do this job

[@gregblau8082]

Since it’s a roller block it would be smart to use a roller cam instead of flat tappet. Something like a gm lt4 hot cam or comp 270 hr should give you around 400 hp. Roller cams use stiffer springs and a different distributor gear. Also most of the later blocks didn’t have provisions for a mechanical fuel pump and some roller cams don’t have the lobe to run one. If either of those is the case you’ll need to run an electric one.

[@diegoochoa3163]

do we need to change the pushrods?

[@hishighness1516]

[@keepondreaming3870]

Love the video! What will be the outcome with Vortec Bowtie heads, ported machined aftermarket valves lifters and a Edelbrock air gap Vortec intake and 2" spacer. 650 carb, would we break 400 hp on a steel head? Or would port match come into play matching heads to intake? How would the Dyno numbers differ?

[@MechaNick03]

quite easy depending on the cam

[@TempoDrift1480]

Can I use a stock non vortec cam with a stock vortec head? I'd like to stay out of the timing chain cover and the oil pan if I can get away with it. Not looking for power just reliability. Daily driving an 85 Suburban, 8 lug.

[@donellmuniz590]

One issue, Rich: You said, go to the boneyard, get a Vortec 350, and add this cam, lifters, and springs. But the stock Vortec has a roller, doesn't it? Are you advocating trading a hydraulic roller for a hydraulic flat tappet?

[@greddmyles3677]

He said get the vortec engine and add the springs and induction system

[@007dws62]

I’m doing this near exact upgrade except I’m going with a slightly larger Lunati cam. Also my mechanic is recommending a set of roller rockers. What would you think the rockers would be worth in hp gain?

[@88classic]

1.6

[@w8e0s6t]

He forgot to mention that if u do get a vortec motor ur gana need longer push rods with this cam setup do to different lifter lengths.roller cam got longer lifters so they require shorter push rods as for the flat tap cam has shorter lifters and require longer push rods ..I'm going threw it as if now ..c what happens 🤞

[@karleastman5456]

Sad that this video did not include a dynamic pull.

[@anthonypickens3236]

so no other head work was needed just change out the valve springs?

[@unicornsteaks6769]

Correct. But use the correct rockers and push rods for the Vortec heads. There are limitations to the lift these heads can support due to the pressed in studs. You can ask the cam company for the right combo.

[@leonhoule7342]

The retainer in the spring kit they used is thinner and allows more room, otherwise the retainer would hit the valve guide.

Hey how you doing I was wondering if theres a superchip that can give me more HP and Torque for the Vortec 5700 L31 , mine is a 1999 year

[@killercodplays]

Superchip?

[@senpaimike9014]

@@killercodplays yeah like if there's a chip that I could install to make my engine better with HP and or better MPG

[@failfail715]

Senpai Mike 901 I mean you can but they really do t do that much unless you have a intake, exhaust, etc

[@darrylbrown4790]

No, there isnt for that motor. And all those "chips" do(the real ones not $50 or $100 ebay ones) is change the tune. A tune on a bone stock vortec l31 is going to be worth very minimal gains in comparison to what a cam & springs would do, like in this video.

@@darrylbrown4790 I see thanks for the advise!!!

[@scatpack3663]

How about if you just add cam will I need to change something else for Sierra

[@Compcams1976]

You will need valve springs at a minimum with any cam in a 350.

Is this set up for a truck or would it be a good combo for a lightweight track car

[@Compcams1976]

Really depends on what kind of track use you're doing! Give us a call or shoot us a DM on social media and we can help you get set up!

@@Compcams1976 I'm wanting to build a drift missile hot rod. Ls swaps just seem too damn expensive to convert to a manual trans. Figured a t5 could handle some abuse from a set up like this. Also, what octane was this run on, I never saw it mentioned

I have that short block in 1/2 ton and am upgrading to Vortec heads. I'd like more power if it won't hurt the fuel economy and the ability to do moderate towing

[@marvinnelson4492]

I put 305 heads on a 350 5.7 motor and the heads dont match the tb intake that was on it t

[@lilporno6583]

Marvin Nelson you have to get a port matched intake bud
