Hi guys, new to the forum. I purchased a 1973 Tahiti jet boat with a 455 Olds over the summer. Decided to pull the engine and refresh/rebuild it over the winter. Guy I bought it from didn't have too much knowledge on the boats history so I want to make sure its good to go for next summer. Since I'm doing it Id like to get a little more performance out of the boat. Planning on getting it bored .30 over and installing a bigger cam (to get that lope sound) as well as getting some head work done. Not quite sure on what cam I should go with or what I should do with the heads to get more performance. As far as I know it is stock besides and Edelbrock intake. Any advice is greatly appreciated.
