Good deal, dude.
I've got a built 482" to go in my 85 Berlinetta. Just working it a bit at a time as my funds are limited with a wife, mortgage, three kids, two dogs, a Harley, and three cars. I was lucky enough to get a set of Lemons headers off of Ebay for pretty cheap. They were in excellent shape. They go for over $900.00 new from Lemons and fit better than the Hookers. In the block I got TRW 13:1 pistons, steel crank, h-beam rods, topped off with a set of 074 aluminum heads(from Ebay, also).
Just gotta swap out the motor mounts and drop it in now. Got a bonus coming from my job so maybe I'll get this project completed real soon.
