engine build questions
Questions on a engine build. I have as of now a ECS installed Novi 2000
AR headers, meth etc. all on a stock LS6. As of now @ 6-7 psi 581whp.
I want to build a new motor soon and I'm wondering with these blowers where if any is the sweet spot of psi. I don't really care about crazy hp #'s be happy with anywhere in the 700whp area. My real question do I build a 346, or buy a LS2 make a 402 or a little bigger a LS3 like a 416 and run more power from the motor and less boost. I know all 3 have no problem hitting the power level I'm looking for more or less want a real realiable power plant that doesn't have to max out to hit the numbers. I'm going to run this past ECS as well because most likely they will do the work but would like the opinions of you guys.

I will, you said that in one of your replys in the past. I guess what worries me if something happens to the motor now I'm stuck between the tuner and builder.

They did a stout 408 (dragonslayer cranks, billet rods, custom pistons, pinned and girdled mains) for a buddy of mine earlier this year and the customer service and quality of work was second to none and was above and beyond anything I've seen in this industry in the past. They set the bar very high for future transactions, that is for sure. I am not the type that gets impressed easily either.

Plus that Novi 2000 will put the power down for you. The only other thing other than the reg stuff get the main caps drilled & pin.. Robert

I agree. If you want a build do an iron block with rods and pistons. Aes recommends changing the oil after every 3 passes at the dragstrip for a street motor. Anyone that recommends that i cannot take seriously.

If you are not worried about really crazy power look at a stock bore motor are keep it under 400 ci that way the walls in each hole will be good and thick. More metal in those places will make you have less heat problems.

Hone it out to 3.905 and stuff it with forged parts, pinned mains, and main studs.
Get your Tuner, Doug, to spec a cam out for it.
Keep the stock heads, changed the intake valves to ferrea hollow stems and super alloy/inconel exhausts and use a good spring kit. Use stock rockers with the Comp trunion bearing upgrade. Tighten them down with basic ARP head studs and stock head gaskets.
Done... It will make power.

Does anyone do 383 strokers with boost anymore? A few years ago there was a 383 LS1 with an F1 around my area that was pretty sweet 800+ wheel.
A 6.0 block with LS3 top end would be pretty nice "budget" build.
I would just get forged rods, pistons, etc and stay stock cubes and stock crank.
There is a certain forged 346 on here that runs 9.1 with a 6 speed and soon to be in the 8's.... Made me a believer

Keep your block & put money better rods & pistons & rings, stock crank will do fine for the #,s you are looking at. Then a set of good worked heads with good springs.

Your most economical way is to just install rods, pistons and a cam to your present engine. Heads if you want to go crazy, but with or without you will easily make 700 rwhp. Feel free to give us a call anytime Dave if you want to discuss your options in length.
We also do not have any issues working with a purchased engine, we do it all the time.

about to pull out a ls2 427 built by HKE/DP that has less then 3500 miles and has way to many issues.. main reason is the bearings are way to tight.. guess what that motor cost for a 3500 mile life span??

You can get all that with ECS. Robert

You do know that stock cam stock heads and stock everything everything else with a blower turned up will make 700 right?? Usually the ring glands goes anyways so really not big chance you would mess up heads or cam either. I see way to many people with monster build that end up not driving their car or selling it because it becomes cumbersome with all the issues and the amount of money spend on top of money..
