Engine build on the brain

I fixed it Rob
I was trying to say he needs to stay away from .060 to .100 open space between piston and head - he has no quench
check out Icon 982,983,984 depending on head ccs, gasket and how much compression he wants\he can get some quench
I was in on the design of the B versions of these pistons with United chief engineer John Erb (retired) many years ago
we had lots of miles and dyno time on the development with both gas and propane (who was paying the bills)
hell have to do a mock up to get it dialed in but I recommend doing that anyway
do this and low end and mid range can be picked up
less fussy on gas and timing
now if he is always going to be running above peak torque (trailer queen) then he can make open chambers and FT work
top end hp might even be a little more -very little
