Throttle body porting

sometime in the future I will be around. I’ll let you know

how much to make my dinky 48mm LT1 throttle body into a dinky but not as dinky 52mm?

how much would it be to freshin up a honda d series head… just like new vavle seals and clean everything up

PM’ed

I was wondering the same thing…since its twin blade

Same here i was interested in dropping off a cylinder head from a honda d series motor for porting…
