Im currently building a 482 BBC with Merlin 345 cc runner steel heads. it has 4340 Eagle Crank and rods and SRP Pistons. Would it be to much to add 200 shot ontop of that? I do not have the rotating assem. put together yet or new rings . What kind of ring gap should i have on the pistons for a little nitrous?

I suggest a .020 gap on the rings for a 200 hit, it would be fine, you would have no issues with a 300 shot if you wanted, but that is the safe limit for the SRP pistons, but if you want to go that big you would want to gap the rings a bit more.

Yeah I was going to say closer to .025

I think my 482 was set at about .028, and I was hitting it with 2 kits, a 200 and a 250. Worked just fine for me.

with 345cc heads put as much juice as you want to it, just have good fuel and pull plenty of timing and work your way back.
