I'm not sure if this is the right place to post this, sorry if it isn't. However, I recently picked up an 89 camaro that has a rebuilt 305 in it with a carb. Since nothing on the engine is stock(except for the heads), how much hp would you estimate it would now have?

 

You'd have to know what's inside to estimate correctly. I'd think somewhere between 150 and 200 though.

 

You are going to half to tell us whats insside to take a geuss. It may be easier it have your car weighed and then run it down the track. That would take a lot less wrenching. Other than that you could be btween 50 and 500.
