Hey guys, Another fast question regarding my T-56 Swap. I will be attempting to mate the Camaro T-56 to a Mark IV 454. The engine is out of an auto. Will there be any issues concerning the fitment of a pilot bushing into the end of the crank or am i just over-thinking the issue? Just trying to cover all bases; thanks for your replies in advance!

as long as the rear of the crank is drilled for a pilot bushing, you should be able to use a stock bushing- or you could upgrade to the roller bearing that GM sells.

Press the bushing or bearing in. Pounding is going to cause grief.

I understand the concept if install and removal Keith, i was curious if ALL Mark IV crankshafts are machined to accomodate a pilot bushing. In other words, if a particular motor was out of an auto, would there be accomodations at the crank end for the bushing? I don't care about any other provisions on the block that would be particular to 4 speed, such as the treaded hole for the Z-bar pivot, as i am going hydraulic.
Thanks

the only crank i've ever seen that wasn't drilled for a pilot bushing was from a 400.
99.9% of them got drilled, so i wouldn't sweat it.
and what tool does one use to press a bushing/bearing in? i've seen pullers, but not installers. light tapping with a small hammer installs them in about 10 seconds.

Yeah Derek, i kind of figured as much. I think i was getting confused with the Chryslers, did you know that the absolutely have manual/auto specific crankshafts? The autos have NO provision in the end of the crank for a pilot bushing. at least the vintage motors. Weird. As far as removing a pilot bushing, i just know of using the alignment tool after packing it with grease to help pop it out. In, just the way you said unless there is a tool i've never used...
