I have a question for you guy's. I have just built a balanced 460 bbf with aluminum heads roller rockers and a few other of the goodies. I purchased a new 12 berkely pump that I had balanced with a a/b impeller and installed a loader into it. My boat is a 18' sleekcraft. The deal is that i have a offenhauser tunnel ram with dual holley 600's. But my jet builder told me that since my exhaust goes through my transom that I would loose a 100 horse power and the tunnel ram would not be a good idea. He said I would not have enough rpm for the tunnel ram to work correctly. I have purchased a edelbrock performer with a 850 edelbrock carb to bolt onto it. I was finishing bolting the engine up when I made the mistake of setting the tunnel ram onto the block HOLY SHIT it looks good. But I know that I will also get 50 hp out of my flame stickers. So any ideas?
Thanks,
JW
