I'm not very auto savey so i realy couldnt give u any specs, but im very interested and eager to get her very hogtight. the pipes r straight back though. my cousin gave me the car a year ago, but it sat up in my grandmas yard for 7 years. just b4 he went upstate he had it dropped into the caprice. i believe it came out of a 79 pickup. i didnt realize what i had until i took it to the shop 2 have the rocker arms done, i thought it was a 350, but a mech showed me how 2  identify it by the heads. (i quickly found out that opening your hood is like letting someone look under ur girls skirt) he tried to steal it from me. so tell me something good, i dont mind gettin my hands dirty.

What do plan on doing with the car, is it just for the street? How much money are you willing to part with, and how much of the work do you think you would be capable of doing?

I just thought of this, the March issue has an article on the Engine masters Challenge winning 400 small block, called Common Sense Small Block. It makes about 673 HP, but might be a little over the top for you car, hahaha

Sounds like you need a lower rear gear and a higher stall converter to get out of the hole better. After that, time to look at weight reduction.
