I wouldn't expect miracles. I would learn to tune the carbs, put in a good advance curve in the distributor and educate yourself on tweaking the combination. I wouldn't expect more than 350-400HP at the flywheel but run it and upgrade it down the road as you become bored with it.

My only concerns is with a 2 ton car I don't think 350-400 hp will do much for it haha.

Edit: But to be fair it could be perfect, so we'll just have to wait and see.

You're probably only 200lbs heavier than a 68 B-body, so .2 slower in the 1/4 mile. Not the end of the world.

Probably closer to 500 lbs haha, but gotcha like I said well set it all up and see how it is and if I can dyno it it's a bonus.

Thanks for your input and thanks to everyone else who helped me on here too it's been a big help!
