Now for the good part guys.....400 motor complete....400 4 bolt block only...complete 327 motor....all for $160 with guarantees that all check out OK for use!!! And the bonus is that the 400 had a Rochester 2GC carb and i think it may be the big one that I could sell easily!! What a bargain!

There are 4 casting #`s for the 400

330817 (2 bolt)
3030817 (2 bolt high nickel block)
3951509 (2 bolt)
3951511 (4 bolt)

Any of them would do good but if you could find the 3030817 high nickel block that would be my block to run...
