Frankly for the amount it will cost for the actual unit, the upgrades to the engine and outdrive, and upkeep it is just easier and possibly less expensive to just go buy a bigger engine.... 650 maybe?

You are correct. I had a dragster back in the 70's and have worked on engines for both bracket racing and circle tracks. At one time, I had a 1975 21' Raysoncraft with a 640 blown Ford by Holman and Moody in California. The blower was a whipple charger. Holman and Moody replace practically all moving parts with racing equivalents. It was a great setup.

My choice for engine rebuilder today will be Teague Marine in California. When I bought my Formula, the 7.4 litre engine was tired and the valves were tuliped. I replace it with a bobtail 454 Magnum from Mercury. That way I had a 2 year waranty on the motor and was able to 'drop in' the engine. After breaking it in, I didn't like the way it sounds as it seems to be skipping and at times, 'running on 7 cylinders'. A number of good mechanics around the lake could not figure out what is wrong. I finally gave Bob Teague a call. I was surprised to get 'the man' on the phone. He made several suggestions over the phone and is extremely knowledgable. After replacing the stock coil and wires with Jacobs brand. It ran great! Then I replace the needles in the carb with ones that he reccomended, as well as replace the prop with a Revolution 4 blade. It had literally woke up the boat. I am having a blast! If you need technical advise, I would give him a call!
