Wow: This is a lot of valuable information. I have done some more research on my current chevy 454 engine and have found the 3999289 block to be a 2 bolt, The 336781 heads with flat pistons pretty much sucks too. What is that 8.1 compression or less!! The guy that refreshed the bearings said the cam was barely over stock but did not give #'s. It looks like to me that this is bare bones stock 215 HP motor with a mini thumper cam. The only thing it has going for it is the Chrome Zoomie pipes that are very loud!! I am not interested in RACING this boat. I am content to cruise and ski. My vanity wanted a much stronger engine but if I can floor-board it all day long without failure it sounds like this is probably the right motor for me. I was happy with the way it ran before the intake change. I would throw my billfold at it a little harder but this engine profile doesnt seem worth the effort.

I have a marine accel distributor and feel that it not posing any problems with my accel super coil 40001-w/resistor and good wires. It might have a advance problem but it looks very clean. I am fairly sure the TUNNEL RAM was the downfall on this stock of a motor. The Carter 500 cfm carb was on here from the git-go. If I find a smaller intake with the HEI clearance I would still like to keep the LOOKS of the super coil. But I am not married to the coil. I put this intake on because I saw so many of them on other boats. I think those boys had performance engines, better pumps and deeper pockets. I am just wanting a sunday cruiser... I want to thank everyone for the EXPERT advice and time out your schedules to help such a chevy engine layman....I think I posted a picture of the motor and if I didn't I will. With that said I will be selling the OFFY TUNNEL RAM SILVER POWDER COATED (NEAR) SHOW QUALITY INTAKE. If no response from here I will throw her on Ebay..Oh Yeah- I need an oval port aluminum intake for this stocky motor.....
