Brakes
It has the entire system from the Monte Carlo donor car. The truck only has a mild lift cam (488) and makes good vacuum with the 305 SBC. In a panic stop the brakes just slow down the truck but not like they should. I have to get this thing fixed fast. My wife wants to cruise and she wants to cruise now.
I think I may just replace the booster and master cylinder and see if that cures it. Thanks for your reponse.
