IMO that hp level to the wheels isn't that bad.OonDeanisS said:i have ported E7's (2.02 intake, 1.60 exhaust) with 1.6 rr's on my 351w and it only put 281/307 to the wheels with an edelbrock air gap intake and holley 750. This is also with a full exhaust
by the way, my 1974 351w has firing order 15426378, not sure why.
off topic..... Ooondeaniss do you have a link to your 86 for sale?
