Building New Small blocks
This coming off season I plan on building 2 brand new engines for my Formula. When I say new, I mean Blocks and all. I will sell the stock 350 mag MPI's that come out of it. I plan on building either 383's or 400's (depending on the new dart blocks I get). I'm not looking for huge power but would like to see between 425-450 reliable hp. So I'll get on with the questions.
1:What would be the best hydraulic roller marine cam that sounds good and has good mid-top end? 2:What would be the best ignition system, HEI, box triggered etc.? 3:What would be the best carburetor? 4:What would be the best fuel injection? 5:Would the stock fuel pumps be able to keep up? 6:Would I be able to use the serpentine belt drive systems off the old engines? 7:Would internal balance or external balance be best? 8:How much are good-running 350 mag MPI's worth? Any input is appreciated !! |
Bravo drives? How many hours? |

Have you ever considered LS power? The numbers you want would be extremely easy to make with one and be extremely reliable. You wouldn't have to get aftermarket blocks either. A bone stock LS2 (6.0L) makes 405 hp. It wouldn't take much to get you to 450.

Id think that some old school small blocks with 174 blowers would be a pretty inexpensive and reliable rocket. 500hp on a mild build will give ya a 1000hp boat and bravos that may survive. |
This was a pretty good thread.
