No 3.2 high c/r???
Also, everyone tells me wilder cams are less wild in bigger engines. I mean, what is your definition of gas guzzling?
The chap who has sold me/built my engine has a 3.6 with bigger high c/r p&c to make 3.8l with (old, cheapish) MoTeC running injectors mated to genuine early RSR 50mm throttle bodies, and he gets ~27mpg on the highway... He gets about 7 or 8mpg on the race track though
Actually, for your benefit he has about 350hp at ~6500rpm from the 3.8 litres and has GE-80 cams and, I think, 11.3:1 c/r. This should give you a rough idea of the sort of power to expect (eg, if 3.4, hp = 350/3.8*3.4 = 313hp, give or take depending on a bunch of factors).
I can't decide how to vote... yes I can - GE80 cams with a 3.4 twin plug. No replacement for displacement but I understand 100mm p&c are more expensive (buy and install???).
MFI - I suppose so, but I bet trying to buy and get a pump calibrated for a 3.4 costs more than converting the same throttle bodies to EFI...
