You may have to check on pilot bearings or get one machined to fit your application but that should be pretty simple.

I was ignorant of the pilot bushing/bearing issue when I had a late 70's short block rebuilt to replace my 87 and go under a 4.0 head. I soon found out though, when I went to put a pilot bearing for an 87 in the late 70's crank and... DOH!!! [img]images/graemlins/shocked.gif[/img]
As it turns out, the '87 bearing almost fits inside the '79 bushing. And fortunately I had a friend with a small lathe that was able to ream it just enough to pressure fit the bearing inside. [img]images/graemlins/blush.gif[/img]
My only other note of caution would concern the fuel mix and ignition timing. I had no easy time getting rid of detonation while still getting decent power and mileage. When you go with an engine configuration that never existed from the factory, you have no baseline or point of reference for tuning it. I dunno... maybe a Howell or MPFI kit would fix all that, but it took me a fair amount of research and more patience than I wanted to yeild to get my Holley and Duraspark dialed in.
...on the flipside, now I get to enjoy one awesomely sweet howl when I squeeze on that go pedal. [img]images/graemlins/cool.gif[/img]
