I must admit those were tough questions, but I did get answers.
As to computer flashing, no one does it on a OBD1, any more.
The largest cam is a .486

Thanks for all your help

Thanks for replying to your thread and supplying answers. Though I had no use for them, others in the future might. Always nice when people do that for a good resource.

As for your U19, what changes did you make and what kind of speeds are you seeing? Are you running the duoprop or the SX drive?

I have installed a trick flow R series intake, a 486 cam a 75mm throttle body, roller rockers, some flow work to the stock heads, .010 larger intake valve and .060 over.
Last year the boat ran at 72 on the odo.
I ordered a 25 pitch prop and expect to run around 76 this year,,,,,, not bad for a small block!!!!!
