Hey everybody - my dad's 94 Formula convertible has been parked in his garage for 9 years - not running. Before he parked it due to medical issues, he put a Jasper rebuilt engine and auto trans in it (about 10 years ago).
It's rough on the outside - paint and interior are not great - trying to decide it if I should tow it to a shop and spend a $1000 to get it running. Any estimate of value on this one? Thanks in advance for any feedback ..read more

I have a 94 z28, and I'm going to take the doors I have on it now off and replace them with manual window doors because the old ones are falling apart (fiberglass splits and all). I've never taken a door off and put another on so I'm just wondering what the procedure is and what tools I'll need. I'm going to be doing this by myself if that matters ..read more

I have a 1994 trans. I just rebuilt my lt1 this fall. Here is what ive done to it. New crank, .030 over speed pro pistons, .020 milled on the heads, hot cam, mid length headers, cold air intake, high volume high pressure oil pump and I think that's it.
I would like to install 1.6 rockers but I'm unsure exactly what I'll need. Some people say you don't need to change the springs/retainers but I think I might as well change them. Does anyone have part numbers or direct links to what I'll...
