I built a 512 for my Super Bee last year, and here are the basics:
.040 over 400 block.
Source 4.25" stroke bottom end with the lighter crank and upgraded rod bolts.
TF 240 heads, Scott Brown solid lift cam, Hughes 1.5 rockers.
10.6:1 compression.
I read a bit on intakes before I chose one, and then put out the word looking for an M1 or a Holley Street Dominator.
A friend thought he had a SD, and it ended up being a Performer RPM, so I picked that up. Then I found a screaming deal on an M1 single plane. I put the M1 on, but got to talking with Cab Burge and he says the RPM would be a better choice.
What do you all think? I am pretty sure the M1 gives me more hood clearance with the N-96 air box, but I know an RPM will fit, I had one on the previous 383 that was in it.
It's going in my '69 Bee, 4-speed, 3.54 Dana. Suspension will be switched over to either Assassin Bars or Cal-Tracs once I get it all back together.
