Wow, I only use 84# Delphi's in my blown LS1 and it will make around 850 rwhp on the blower, and I have a T-Rex pump driving my small wet shot. I see you've adopted the principal of "buy more than you think is required."

 

thanks for the help with the rods Mongoose. i was wondering if the 5.87s would have room for a beefy ring land.
as for the 160 injectors its a price issue. 160 for $450 compared to $600+ for 75s or 83s. i know they might have idle issues and since i haven't acctually purchased them yet we are still looknig into how they would run.

 

Gearhead.. my suggestion is as rich has said a few times already...

Its a better idea to make the engine last a bit longer if you do a 383. There is not that much difference between a 383 and a 396 in power overall.. You will have the ability to spin it a little higher and still use a 5.7 rod to have a thicker piston... I am going with the combo said in one of the posts 383 31cc dish pistons and 62cc combustion chambers... That yields me a 8.8:1 with felpro gaskets...

I will be in the dept of 700-750 which is less than what you are doing now, but I believe rskrause is in the 100rwhp range already. So might as well listen to him I have all this time and had GOOD results... Also.. if you are using a m6 go with a street twin.. it will handle 1400HP unlike the spec 3.
