Don,
I don't know if you're aware of it or not, but the HP rating on the 76 engine is net HP. Taken at the trans tailshaft with all accessories installed. They changed the way the listed HP in '72 or '73. At the flywheel with a bare engine you can probably add 50 HP or more. From what I've read most of the 60s and early 70s were rated between 240 and 265 HP except for the high performance engines.
I've got to do a little work on the A/C. I've got a remote condensor on it and it doesn't really do a very good job. I need to mount it in front where it belongs. It cools, but not nearly as good as it should. Gonna need it in a few weeks.

Oh yeah,
Thanks for signing my guest book on my site.
