I built a sbc 350 for my boat last year. 87 350 flat top 78cc heads comp cams ( I dur .218 e dur .224 I lift .460 elift .477) stock intake qud 4bbl. the moter runs good but the power flat stops pulling at 3800rpms .run a compresstion test and got 120 to 125. I would like to get 325hp out of it but I dont think got it. I thinking about changing the heads to 64ccs and hope that would work. thanks

Sounds like your valvesprings may be too weak or your running out of fuel at the carb.
