I'm in the process of building a 408 stroker. My goal is to be around 900 rwhp on boost. Anyway here is what i'm thinking
Callies Compstar 4" crank
Callies Compstar H-beam rods 6.125"
Wiseco 4.030 -20CC pistons
Clevite main and rod bearings
Right now i'm thinking of using my port and polished 243 heads

What block you starting with? 6.0?

If I were going to buy new pistons, I would be getting something to work with L92 heads. Sell the 243 heads, and get L92 heads that will flow better and be cheaper. But that combo with a large turbo should get you there.

Yes it's a ly6

Thanks ill look into the l92s I was hoping to not have to spend a whole lot on heads

If you have the LY6 it will already have those heads on it. I believe they should have 823 cast in the front passenger side corner of the head.

Parts look fine, but the machining/assembly is more important than the parts brand.

You can make plenty of power with 243s, just size the turbo correctly.

i just brought the block im picking it up today from the machine shop

Im going to have the assembly balanced by texas speed and thinking about having it checked and assembled by a shop down here. Right now i have a 76mm precison im going to use for the time being and later switch to a 88mm

I've seen nothing but failures with the precision 88's recently. I think there was even a failure on this site not to long ago. I'd look into the Borgs if I were you.

I used callies and wiseco in my 408 and really liked them both. Great quality for sure

im not 100% set on the pt88 im open to options but right now the pt76 is just what i have to use for now. I got my block back from the machine shop yesterday so its ready for a rotating assembly!
