I'm close to 700 whp with my current set up and I'm running stock LT1 fuel parts all the way around, and I run pump gas without any fuel adders. The advertised flow you get from the LT4 stuff is marginal to begin with, and is not what you will get in the LT1 platform because the fuel lobe on the LT1 cam isn't as big as the one on the LT4 cam. There are a lot of people on here that speak often about this glass ceiling the engine has and this max power in the high 500's or low 600's, but I have 31k miles on my car and did all my work around 11k miles without any issues what so ever. I did switch to forged pistons when I got the new pulley for my pro charger though. Way to many C7 guys cracking pistons when running high boost. Venting the crankcase goes a long way with the eutech pistons though. The ring lands do seem to be weak.
