    Wow.... that took awhile to dissect that post...

    Instead of going that route, look into an LQ9 truck block and build a stroker.

    OK take it easy on him, He is new and it sounds like his brain is working overtime. That is a lot to disect though.


    Bro, make sure you use proper punctuation on here. People can be very brutal, trust me. You have thrown alot out there. I built a 408 a few years back and sure loved that engine. It took a 300 shot like it was just a breath of fresh air. Do not get sold on all the big name stuff, it is good but can be built alot cheaper and produce more horsepower. My next build is a low compression 408 with 91mm thumper series. I hope to make around 1100 rwhp.

LS7 heads are big! they say 4.00 bore or biger for LS3 heads. sorry id been up all night. with a 24 tooth reluctor wheel u can use the stock computer right?. with a ls7 and harness to make it work u cant use stock guages!. i think u can get LS3's in the 24
