Re: [BaadAssGremlins] adaptor installed in rear of crankshaft to fit 727..who does them?

[Davis Martin <martin-davis@xxxxxxxxxxxxx>]

Ok well 401 would be better more cubes is more power generally. Are you gonna turn 7500 rpm's ? That is about when the revvy motor would perform better.

 I have the bolt on kit and, now that I have seen it, next time, I will have it made. all it is is a machined large washer with a step for the flexplate to center on. The block spacer is just cut out of a hunk of 1/4 plate steel. I will try to get pics of it on here.

 I was gonna build a 401 using my 70 390 block n rods and get a 401 crank. Got the crank and now found out the block is not the greatest. Was told it needs 6 sleaves! 1000 bucks to fix. SO....Been lookin for a 401 block.........have decided not to do this build for a while now. I will just use the 343 thats in the car for now.
