tuning advice wanted

I think you'll be ok running that much with Gas, with alky that would make me nervous.

I know Jeff likes a lot of compression on his 10 mil with alky, but...he's a dune rider not a 1/8 mile guy.

 

I'd make sure you have a properly cut dome and maybe a little more generous squish with that much PSI and 1/8 mile, like low to mid .050's.

I have 190psi with 20cc domes and .053 squish. I got the domes from jeff also. I cant explain the jetting, I know everybody says it should be fat on top, but its not. Jeff said thats what it would need and he was right. I have pressure checked it twice, no air leaks and both plugs look exactly the same on chop. I guess it is what it is. I know if i put 160 mains in like mentioned above, i wouldn't make it out of camp without nuking a piston. :shrug:
