I have a 468 BBC circle boat engine that I am converting from injected on gas to a Littlefield 14-71 (fresh) injected on alcohol.
Engine is fresh and is at 13-1 comp now. Dyno's at 750 HP with the gas set up.
I want to start with 5 lbs or so boost and be able to sneak up on 15 lbs with some seat time.
Any suggestions on what drive ratio (pulley sizes) to get the boost I am looking for?
Also, what drive size would you go with? 8MM, 13.9MM, 14MM and why.
Looking for a std. deck BBC tented intake if anyone has one used.
Be good, Jim
