I'm considering getting this motor at some point.

It has Vortec heads. Will my driver's side alternator mount bolt up correctly to these heads?
I have a 350 in my '69.

on my 72 everything bolted up fine. i did have problems with all the brackets that bolt to the intake manifold bolt. the stock manifold the bolt holes are slanted, the vortek are flat.

Thanks for the quick reply. I think I'll be O.K., I don't have anything that bolts to the intake.
Another quick question, what would the size of the flexplate on a '69 with a TH400 be?

Flexplate diameter wont matter on the trans as much as the motor & starter. If you get a flexplate & starter for an late 80's to early 90's 5.7 W/th400, you should be good to go...
