Help build my next engine 402 or 408 for boost
Ok as many of yal know... My h/c ls2 had a melt down.. Only thing salvageable was the crank,drivers side head and valve springs..I bought an ls2 out of an 07 tbss for 800$. Managed to sell the stock 243's complete heads for 360$,injectors 89$, intake 150$... I still have a rotating assembly to sell off.. Well I'm still in a huge debate on how much to bore the block.. I'll be using ls3 heads and going to need another cam.. I liked spinmonsters 228/232 114lsa..But could I find a more boost friendly cam? I have dual spring valve springs already and plan on using ls7 lifters, and maybe yella terra Or just
Do the bearing upgrade on the stock ls3?.. Going to re use my head studs and get the ls9 gasket.. Callis 408 rotating assembly is looking good for me... But I'm not liking the 900$ crank price if mine is still good.. Of course chevite crank bearings is a must and arp hardware.. Money for me is fairly tight right now as I'm buying another house and going to be remodeling it so I'm stuck with about 4k max limit here clutch included.. Goals are 800-900rwhp 93 octane.. So That 4k needs to get me heads,cam,rotating assembly, arp hardware,machine work,gaskets, and a clutch.. Can it be done? I'm doing all the work myself so much advice will be greatly appreciated..

I'm thinking about having IPS tune it next time.. They do have the fastest 1/4 c6 to date... They seem to know turbo ls's well.. Hopefully the tune won't cost another 550$....

That is crazy.
Do it right this time to avoid going through the same junk. Stock crank should hold decent power.

I am no expert, but from what I have read going .30 over is already pushing it. Add boost to that and I think its looking for trouble. I would go less on the bore or stroke it if you want more cubes.

Since im building a motor why keep stock displacement? I guess I could just buy pistons,rods, and send it all to the machine shop to get balanced.. I have a realitive (brothers wife cousin) that works at a machine shop gonna hook me up.. 1/4 price for anyhing I want done..my brother said it's his way for thanking me for serving in afghan.. That's cool as hell. Knocks off some change in the book

Because you can't afford bigger displacement?

$4000 for a long block and clutch that will reliably support that kind of power is going to be tough. If I were you, I would either wait until I had some more money or slap some forged pistons in it and keep the power down lower than your goal until I could build the block properly. If you get this motor put together and hit your goal of say 850. That is going to be great until one day you say it's not fast enough and want more power. Then you have to start over again. Build what you want the first time.

850-900 on (high boost) I think that'll do my need for speed in.. The car couldn't hook from a 60 roll with tc on and my 28in nittos anyways... I'm thinking of changing my gearing up as well...the rpm stage 5 z51 trans with 30 spline mainshaft and B.E.R 3.90 gear diff machined for 30 spline has less than 600 miles on them since (mainshaft,refurbish, and machine work done).. I feel that's a bad set up for a FI car... So swapping that set up for a Zr1 tr6060 and zr1 diff sounds like the better option for what I plan on doing.. After many thoughts about the whole displacement thing.. I could actually use that to my advantage..

Speed is the most addicting drug.. I remember when I thought my stock corvette was so fast... I was beating all these cars... And then my first lost.. After that I just kept
Modding and modding, breaking,modding... It's endless.. Car spends more time on stands than I drive it.. Since I started modding the car.. I don't think I broke 1k straight miles without tearing into it to do something or fix something..

He is a good tuner you just didnt listen to him lol, he showed me the text at like 5pm where he said to be easy on the car until you got it back on the dyno and then the text at 8pm the same day where you said you blew it up....Also he is doing alot of tuning over at ips for them and the guy that tunes marks vette does not do any of the street cars there.
