Chevy 4.3 Vortec V6 engine Preformance Build with part numbers

[@frosteone1670]

Nice, I admire when someone builds their own vs buying a built engine. I used the next cam up 266HR with matching springs, and magnum rockers, wish I'd used the 270HR.

[@christianmotley262]

Why? So you can lose low end torque?

[@frosteone1670]

@@christianmotley262 Cam choice is always a torque/horse power trade off. I have no problems breaking the tires loose on take off, solid shift into second produces complaints from tires again. My 4.3 is far from stock, 10.2 compression, larger valves and ported heads. That being said, Yes I would trade some low end torque for more high end horsepower.

Starting build of 4.3, what did you do to yours? Frost

[@frosteone1670]

@@elreyyakko Crankshaft was ground and indexed. Block bored .030 and decked slightly to match both sides and ensure the deck was 90 degrees from each other. Mains were line honed. Factory rods were clipped and resized, pin end bushed, then balanced. Full groove main bearings and Manley high volume oil pump. Heads were cut for hard valve seats to receive the 2.02 intake valves and 1.60 exhaust valves. Several hours spent smoothing up the ports and matching them to the intake manifold. Milled heads and cleaned up combustion chambers some plus cc'd Manley stainless steel valves, replaced valve guides with bronze inserts. TRW forged pistons with slight dome, result was 10.0 to 1 compression. Double moly rings, both top and second ring. Pro Comp 266HR Cam as I previous stated I wish I'd used the 270H Pro Comp hydraulic roller lifters. Pro Comp Valve springs recommended for the cam. Pro Comp steel valve spring retainers and keepers. Pro Comp Magnum full roller rocker arms with locking nuts. Cloyes timing chain and gears. Chrome moly pushrods. Replaced poppet injectors with GM upgrade to actual injectors. Reprogrammed computer, I own an EFI Live programmer BBK throttle body and aftermarket MAF (no screen) If your curious about this let me know and I'll go look and see what it is. Aluminum body distributor and MSD ignition. Transmission was fully performance rebuilt including a 2500 rpm stall converter I worked in a speed shop for many years. When I did this build I used a friends speed shop that had all the equipment. I really enjoy driving this truck, it's now over 22 years old. (built Oct 2000) Let me know if you have questions, I will try to answer them.

[@elreyyakko]

@@frosteone1670 nice! I plan to go with 2114 edelbrock intake and carb, and compresion at 10.5, heads are my main headache,since cant find info on valve size but now thanks to you know i can go 2.02/1.60. Seems Im more or less doing your build but going with the 270 cam. Truck is bigger, its my dads 90 1500 cheyanne that we restored. Trans is done and exhaust/headers. Rear im thinking 3.23 since its for cruising and car shows. Would love more info on your build. Ive got my channel and i think we can send messeges that way.

4.3 good under turbo/ cam upgrade. Guy on life on limiter made a respectable 400 hp 500 lbs torque with a 800🤑turbo kit & marine intake to replace that Nast spider injection 💉. It's a good engine 👌

[@mobilemowers]

Good luck finding a Marine intake much less big bucks. I wanted one also for my 350 too as is tbi but going to have to go carb cause of that 325hp engine build I did. Can't afford a $1,200 aftermarket tbi thats ust basically a carb anyways.

Even with adjustable rocker arms you have to make sure your pushrod length is correct so that your end of your rocker is in the center of your valve.

[@cashtalks6253]

This might help you or somebody who is planning on building a s10 in with a V8. Everyone always said if you get one with a 4.3 it will sit right in. That is not true. You still have to get the motor mounts plates regardless of what engine it had in it and definitely run the Shorty headers because if you wanna run full length you need to relocate the oil filter and the transmission I had came out of an 88 Chevrolet long wheel base so it had a long tail transmission and it set back in the stock location of the crossmember with no modifications to the driveshaft either. I can tell you this from experience not hearsay because I put this truck together myself but that being said I would build a 4.3 simply because you can make it have plenty enough power considering the weight of the truck and it’s simply not what everybody else does.

[@radiorahim861]

Very interesting man. I never would have thought that you could use a tranny and be able to rock the standard driveshaft. Only other thing would be a wiring harness I'm guess and a tune. I'm just gonna build my 4.3

[@x-man5056]

Rocker arm studs sizes should be related to the expected RPM range. If you built a torquer, you are rarely if ever going to see 5k RPMs. Big studs and rocker arms, and valve springs are just not needed, unless you are seeing 6k+ RPM regularly like in a drag car. Roller tip rockers are nice because they reduce friction/wear but doubt you'll notice performance from them because a torquer (engine with high torque vs HP), isn't going to be running in high RPM hardly ever. My question is, did you put in flat top pistons or run the stock dished ones?

[@mobilemowers]

As I listed in describtion of all parts. They were Silver lite 1436 pistions. Flat top, with four valve reliefs giving a 9.5:1 to ratio or so. www.summitracing.com/parts/uem-1436-030

The marine intake's are rarer and $$. What computer you going to use then ? Snipper is a throttle body kinda of going backwards. Also how you going to control the dash and trans ? Big bucks your talking. Being thrifty if you upgrade to the upgraded spider injectors you should be ok. Factory computers are ok if you know how to tune them. Can even send them out for a tune or use a canned tune. The factory computer can tune themselfs a little bit also. I know someone running 70ish Camero w a turbo runs in the 7's using a LS engine with a factory gm computer. Sniper is only throttle body so you loose some power vs multiport.

[@mobilemowers]

I am not a professional engine builder. I get my advice from my local shop from what I don't know. Talk to who is doing the machine work. I do know if your doing a turbo you want lower compression. Thats why guys buy used engines with miles on them and never do the rings. They already have low compression from use. If you use new rings you really have to open the gap. Power Block TV / Power Nation did a 4..3 Tubro build with over 300hp on KZbin. Super chargers I think can do normal to little more then stock compression easy. They have super chargers that bolt right where the ac compressor would be, Google takes me to www.summitracing.com/parts/cca-12-704-8/make/chevrolet for a camshaft for boosted cars. Just be carefull and never go to high of a cam. You will loose bottom end. Been thier. You can call Comp Cams and ask them. Wait times can be crazy The 2003- 14 LU3 4.3L have injectors for each cylinder not the crappy spider injectors. They are like the 90's LT1's and the 99-up 5.3 ect Vortec's. Might want to swap over to that setup for guys with the older engines. Stock stall converters on a V6 already are higher. So use the stock one. Putting a VY convertor on a V8 will wake it up. Also the V6 trans can go in a V8 the parts interchange may tell you otherwise cause of the stall. I have V6 trans and convertor in my 94 K1500 w 350. Did video's on that. I also posted recently a video of the truck running, Hope this helps. Please like this video and maybe subcribe. Helps my video's and channels get noticed more with thier metrics.

When the shop was checking it for fuel pressure when the top intake was off lots of gas ran in the lower intake. At 60 psi or so a decent amount of gas comes out in 20-30 seconds. That gas mixed with the oil and got inbetween the rods and bearings. So gas got in the bearings and pushed the oil out. So run for a few minutes without oil and see what happens.
