I'd say you're around mid 15's. What kind of gears do you have? Also, I'd say you're 25-30hp over stock.

That would probably be a good estimate. Depending on running condition I would have guessed about 200 horsepower and 270ft/lbs. Ask the TBI guys what kind of cam they could reccommend That could be a winter break project.

 

nah, my winter break project is las vegas
anyway i dont want to put any more money into this engine, i have plans to build up a 406

Open Element Edelbrock Aircleaner w/ K&N air filter should add about 10 hp(maybe)

Edelbrock TES headers 3" out/flowmaster American thunder 3" exaust/Catco cat should add about 25-30 hp

Edelbrock Performer manifold should add about 20 hp give or take a few.

Id say your around 40 hp over stock, maybe more.

You've got the intake and exhaust taken care of. The only other (large)immediate things are the heads and cam. An LT1 cam could be a great cheap idea. I would say since you've done the intake and exhaust already you may be able to see a good 20-30 more horses from the right cam(maybe LT1). Im really not sure if it would work as well for TBI as TPI though, ask the TBI forum guys.
