Hi guys,
Just looking for the APBA offshore race rules for B class boats. I'm going to be resurrecting a staggered B class classic **** top secret**** pics to come
Would love to have it exactly correct per the rule book. Looking for 1990-1995 any year in that era. I know they had specifics on engine set up "heads, cams, intake, compression ratios" and different things like hand rails, navigation equipment, ect.
I've looked up the rules for last years Super boat engines and the different classes, but I have a feeling they aren't anywhere near the same. Thanks guys, let me know what you think, and I promise as soon as I can post up pics I will.

Engine specs were pretty basic - 1. Twin Production Spec (Big Block) - 950 cu in total , 9.5 C/R , Dual Plane Intake , Iron head , any cam/valvetrain. Gil , Hardin , Stainless Marine Exhaust. No headers 2. Twin Modified Spec ( Small block) - 750 cu in total , Single Plane Intake , any head , any cam/ valvetrain. GIL , Hardin , Stainless Marine Exhaust. No Headers 3. Single Race Spec 610cu in total , Tunnel Ram or F/I , any head , any exhaust( headers ok). I think I still have it memorized if I cant find an old copy. Call Anytime - 941-681-1870 Bill D.

Wow thanks Bill!
Seems like the rules are a bit more stringent theses days, the superboat engines even have part numbers and component specific specs.
