After a discussion w/ my machine shop, this is what we decided to do:

Bore the block to 30 over and deck it
Use the stock forged 340 crank I already have
new Eagle rods
new TRW pistons
Edelbrock 340 heads
Edelbrock Performer RPM Airgap intake
Comp Cam 280 mechanical cam/lifters
750-800 cfm carb (undecided on type)
10.5:1 copression ratio

He feels I should be able to get 400 - 450 hp out of it.

What do you all think?
