Ok. I’m asking for you guys opinion. I’m trying to decide what to try first. I’m thinking about going to E85 or having a custom ground cam. I’m looking to pick up .200 ET if possible. It costs about the same either way. About $400. Right now I’m using a off the shelf .292 Comp Hyd. Cam. The motor is 10-1 with Holley heads an Offenhouser port-o-sonic intake and a 650 Holley ultra with a 4k stall and .456 gears. The car runs 12.32 @110 What do you guys think?
The experience that I have seen with people that have chaged over to e85 here is that they had to do a lot of changing of jet sizes and air bleeds and everything else to get car up to potential and they use a lot more fuel at the track. Need more compression to reap full benefits On the plus side once they got it to run good they ran consistant times and are happy with it but then they better be with all the work they had to do. IMO I would just cam it
Cam it. Switching to E-85 will require much more compression than 10:1 or you would have to add 12 - 15 lbs of boost with turbo or blower to get a bump in power.
