keep in mind..the higher the horsepower the more likely you will have to swap the rearend, tranny..your also going to end up replacing other parts as well to accomodate the new engine..but hey if you got the money no problem

 

is a new tranny worth the cost? if its not, then whats the highest hp i could get without changing the tranny.

 

It depends. If youre running slicks, expect a lot less life from the trans. The #1 killer of transmissions is heat, if you can keep it cool and run street tires, a stock 700R4 can maybe hold 400+ hp, assuming its in good shape and has been maintained. Dont expect to help your ET by switching transmissions, usually they are replaced for strength reasons. A higher stall converter will help ETs however.

 

In 83 Belinettas could have either a misfire or slobberjet...uh...I mean crossfire or quadrajet

 

im not racing my car. its gonna be an everyday driver. i just want my car fast and to have a nice sound.

 

headers, exhaust and intake...have fun
