whats the gap ona set of hellfire rings for nitrous any ideas thanks yb

It depends on the bore size. Your rings probably came with a sheet telling you the formulas. I always go a little on the loose side of what the formula tells you. Too tight will be bad news with nitrous.

.007-.0075" per inch of bore size is usually close. Depends on how much nitrous though.

its 4.030 bore 250 shot at the most while im on this what do you recommend on bearing for the main and rod journals on nitrous thanx

 

[joesmithz28]

.0065" per inch should be fine, I gotta think that's what the ring instructions say.

I don't like getting into bearing clearance discussions...maybe someone else will chime in.
