I am a car guy and I dont know anything about boats but I have a question I hope you guys can help me out with.
I picked up a 502ci Big Block 4 bolt main with rectangle port heads casting # 14097088. The guy who built this engine builds racing engines for both drag boats and offshore racing.
I dont have all the numbers from this engine just yet but what I know so far, it is a full roller engine, Eagle H beam connecting rods, JE pistons, Crane roller lifters, Crane duel valve springs, Aluminum 1.7 rockers, double roller timing chain, Merlin High rise intake, Holly 850 DP carb, Milodon 10 qt oil pan.
When I remove the rear cover for the cam I see a grind number HR 296-2S-12 IG and what looks like "CR" below that.
When I look this number up I see it is for an engine size of 305-350 ci.... HR- 296- 2S- 12 IG camshaft - Ch. 305 (5.0L)- 350 (5.7L) V8 87- 99
Why would my 502 Big Block have this cam in it???? Isn't this a tiny cam for a 502 BB?
What kind of performance can I expect from this setup?
Thank's for any help here.
