I am in the process of replacing the engine in my '88 coupe. It still has SD and I'd like to try and keep it but I'm not married to it. The parameters are these, I have a MAX spending budget of $5,000. That has to include anything and everything (including if the new engine necessitates a clutch or trans upgrade, etc...) The car has 140k and is using oil like crazy. My first thought was to go carbed with a crate engine. My second thought was a new short block from Downs Ford, Thumper heads, Tmoss intake, and an entry level blower. Last option is the Downs short block topped witht either the Trick Flow Specialties or Edelbrock top end kits (which apparently require Mass Air Conversion). What do you guys think?
