horsepower estimates.

I can probably learn a lot after I get it to a strip. Just need to order a converter. I've never ordered a custom converter before. Are they pretty good at estimating what I need with the engine specs I can give them? I scaled the car so I know I will be accurate on that. People tell me they will ask me everthing but the color LOL. Just can't wait to see what this car is going to do. Its been a 10 year project. Won a championship back in 1998 with this car when it barely made pro class. IT ran 8.80s 1/8 mile. It was pretty much stock back then.
