Im looking for a starting point. To build the motor from scratch I may or may not go that way. Maybe more along the lines of getting a motor throw it in, then rebuild it onece I have all the parts. This 305 has to go though. Anyone know a good sight????????????żżżżżżżżżżżżżżżżż

Soon to be a 400small block

 

guido on the power adder board has a good 400 block for sale

The block is a 400 2 bolt with 2 freeze plugs per side. I think it is a 1972 core. It has minimal core shift.

I figured $610. That included the following:
maganaflux
align hone
block true (decks)
bore .030 over (406 ci)
hone w/ torque plate
install cam bearings
install freeze plugs
install ARP studs for main bearings

additionally, it was drilled for a standard starter and 153 tooth flywheel and the oil passages were smoothed out.

i have a lot of work in the block myself for clearancing but that may not be of concern but it will clear an internally balanced 400 rotating assembly with 6" rods.

I will take $500 + shipping. I think that is fair considering all the machine work is done.
If your interested, shoot me an email.
