Thanks for your input ! More details : the car is a 1970 S coupe, stock body. I got it as stripped tub. Not having the right 2.2S, I want something that will be agressive, but street driveable. I also think that the E cams are nice for street, but I put thousands for nice upgrade that I would really like to get the benefit of. (Twin plug, PMO and for the body : Polybronze bushings, monoballs, 21/26 T-bars, 19/19 sway bars, Alum. beam and t-arms.) The case is a 2.4T - 5R
I bought the 85 P/C' a while ago, for a good price, when thinking of keeping the costs lower, but being at this point I should maybe resale them and go with 2.7 or 2.8 ? With the same set-up what do you think is the HP difference, just between 2.4 and 2.7?
I agree that 906 or RSR are too much, I thinking toward Mod S or DC40/60 ?
Thanks !
