Erik, I run my Ford mains loose, usually about 3. Guess it works on a Chevy, too. With the Super Stock and a Chevy, we will be stuck running the GM Powder rods, do they like the extra side clearance, too???

Now, because of loophole in the rules, we are considering a 360 Chrysler engine..... Engine builder is figuring out some combinations for us now... Will be interesting to look at them. It's all going to come down to horsepower and torque we can make within the very confining rules. That, and a potential new sponsor talking some major $$$$ with a Mopar in the car....
Yes, Dave I would run a min. of 15 tho..Don't be afraid to shim up the oil pump spring a little or go to the super stiff spring.
All the syn. oil makes me nervous.
We don't run any valve stem seals at all.
I am guessing you guys do run the valve stem seals.
Because if you did'nt run them your oil would be down a lot at the end of the race.
