Great post. Keep it up.
Im excited to see what your boat runs too. I like the 30-33' step boats for making a real hot rod. You're definitely on the right track about RPMs and operating range. Gonna run the low compression until you get bored then boost them? |
This is one of the best threads ever!!! :coolcowboy:

I guess 8" deep pans suck for these rpms, never had this problem with my hardin 14 quart off shore pan, same motor at same rpms! On ANOTHER note, if it turns out this speedmaster intake loses 25+ hp when going down from 3" spacer to 1" spacer I think we may have found 25+ hp that tim full force may be missing with NO spacer on same intake!!!!

Well, were only starting, i have a hard time believing it takes 6 or 8 jet sizes difference side to side to get afrs somewhat close w a 1" spacer vd 3" being okay square jetted. If this is true when i add 2 more inches under dominator the side jetted up should immediately go fat. I will NEVER even be running a carb on my boat but now i have to know the answer, ill run this fvker till its wore out to find out!

Per our convo, I did look up the pan used on the 6200rpm 565 (4.375 stroke) that saw no oil psi issues and it is not the one you have, it was the #18-302 https://www.cantonracingproducts.com...MP-MARINE-PAN/ https://www.cantonracingproducts.com....php?id=18-302 |
