Fuel question.....
I just rebuilt my motor with the help of AZCANNON... who is the man btw, thanks man!..
I put the Wiseco 13:1 piston in it and I know that I have to run race gas.. but what should I use?
I can get C-12, which is around 104-108 octane at $7.50 a gal... or I can get Shell 110, which used to be the Sunoco Power Purple.. Shell bought out Sunoco.. this is a true 110 octane fuel at $5.00 a gal.
Question is , will the 110 be too much for my mototr with the 13:1 piston. I would rather save $2.50 a gal, but not at the cost of my motor.
Please give any input here... I wanna fire up my dale tomorrow morning. Thanks ya'll!!

I made a mistake and ran some race gas through my ATK.
It may have burned up my injector o-rings. Wont know untill tommorrow though.
I think it was canniboomer telling me that there were 2 different kinds and that stock rings couldnt take it.
Not an expert but I may be needing new injector o-rings.

Talk to Brad at BW. He's got them for like $10 or less and they're the better ones fro race fuel. I ordered some awhile back and they haven't failed yet. The stockers can't take the added octane number so you must buy new ones that can.

I carry sets (4 pieces) of the injector o-rings made of viton rubber. MUCH more resistant to race fuels. Price is $8.00 for the set. Of course it's only $5.00 for the set made of nitrile rubber - if you don't use the race stuff.
What 13:1 Wiseco piston is this? I hope that isn't what people are saying about the ones I sold! That special batch I got from Wiseco is only (and has always been) a 12.3:1 ratio. Of course, that's up from the 11.8:1 from the factory stock piston. That provides a significant increase in performance - but it doesn't need race fuel. Should run just fine on premium no-lead!

You can take this advise or not but I can send pics of some melted pistons. I would run 93 octane and use a fuel booster but only use about a 1/4 of it per tank. This has happened to both a 450 piston the stock 432 piston. And we didnt realy see any diffrant power when we ran 110 mixed with 93. But its your motor.............:mad: Just wouldnt want to see this face...

I take it from your post you are saying the higher octane melted your pistons?
As for power...I think Tim and company saw a 2hp difference when he switched to the 110 mix at the dyno last weekend.
