Where's the counter?
I'm on a pretty tight budget though.
How far off firewall is engine and where did you find motor and trans. mounts.?
S & P for the motor mounts, about $89.00 and Bowtie overdrives for the Transmount, about $189. I made both and I'm out about $30 large. The engine sit about 3 inches from the firewall. Also the stat housing will not work, the A/C has to be mounted on top with custom brackets, heater outlets don't work, and the driveshaft will have to be cut. Just so you know, even on a poorboy budget, expect to cash out $2000 for just stuff. i.e. Harness, ecm programming, exhaust, etc. etc. Good luck. Buddy

Thanks Budman, I 've been looking for a project for awhile now.
Maybe this will be a good one, at least I've got a good chance of
some $$ return with a vet. even a hybrid. Easy 13's and milage in the
20's for under 10k (hopefully) ,beats a v/8 vega.
I'll be on this forum asking for help and advice often.

Budman, have you decided on a pulley configuration? I also had an F-body LS1, I purchased the vette bracket for the alternator and power steering pump and bought the power steering pulley from S&P. I tryed using the F-body pulley but it is way too big. I also bought the A/C bracket from S&P, if you don't want A/C they also make a delete pulley that goes on the upper passenger side.
I'm staying with the standard F-Body setup excluding the A/C set up. There I'm thinking about going with a late model smaller Sanders or Nippon compressor and a custom made bracket up top. Reconfig the belt routing and that's it. I like S & P brackets, but way out of my budget. I will probably just buy their fuel lines and PS hoses. When funds permit, I would like to trailer the car to them and have them fab up my headers.
