400's are nice big blocks. My brother had a 68 Firebird with a high performance 400 engine, that would squeal rubber at 60 mph if you hit the gas, the gas gauge would also take a dive!

I had a Poncho 400 in a 70 Grand Prix SJ and remember the same scenario; great power and loved to guzzle fuel.

I did some prep work tonight; I couldn't find the right oil pump pickup for the rear sump pan anywhere as it's out of production and the pan itself was hard enough to come by. So I just welded on a 6" extension and it looks like it will work and clear the crank fine. Also pulled out the clutch pedal as I'm going with a 727 trans, pulled out the 5/16" fuel lines and pulled off the exhaust. I hope to get the short block together next week if the machine shop gets my pistons put on the rods.
