I got a phone call the other day from someone who wants to buy my current setup. The thing is it is not for sale but for the price I threw at him I would sell it and build a low compression 427 and would want to procharge it. That is where I need your guys help on the build. I would go with a twin intercooler setup but other than that not sure if I would go with a F1 or a
D1. I am not looking to have to build an LSX block with top of the line parts but would like to build a decent LS7 block with maybe around 8-10 lbs. 800 rwhp would be fine. I do not need the 950 that some guys are doing with the F1 and 18lbs. Let me know what you guys feel would be the best options with money being an issue. Thanks again.

LS7 427ci good H/C/I Setup with F1A Procharger FMIC should get 850rwhp+ with pump gas at 13-14 psi No problem.

since you dont want more 800rwho then go with 4 bolts heads AFR ,TFS or LS7.
but your rearend will go boooooooom.
