396 to a 427 Need more HP
Built my 69 C-10 short/wide in the early 90's to tow my 69 Camaro vert to the shows. It has been outside and used for hauling projects and has about 10k miles on the BB engine. Time to be restored again and this time will be garaged. I would like more power from the engine without a full rebuild as it runs fine. The engine is from a 68 Camaro (it doesn't care) a 396 bored to a 427 with standard 427 pistons, 9.5 to 1 compression, Original oval heads with hardened valves and roller rockers. The engine builder installed a "RV" cam. for towing. Edelbrock Performer intake, 800 DP Speed Demon, headers with 2.5 Flowmaster, GM HEI, 700 transmission, 373 posi, PS, PDB, AC. lowered. I am thinking a cam change and Aluminum heads and less carb. Your thoughts. Oh the engine was already bored 60 over and no pistons were available then, so I was told, so it was bored further to accept standard 427 pistons.
