Equipping a G-Body with a manual trans

[pontiacgp]

thee are no cranks for manuals or automatics....there are just cranks and a pilot bearing will fit your crank

yes...if my crank was a chebby crank....but its not....its an OLDS. I guess I should have checked w/the "Doctor" first before asking this question...lol
just for the record.....

he has 350 in his signature so it kinda obvious he has a SBC since if it was an olds engine that would have been included in the signature as bragging points..

FWIW I have never seen a Pontiac crank that had not been drilled for a pilot bearing. Even on years that no manual trans was offered at all.

Just curious Bonne, but how can you tell the difference between them, without having them side by side to compare or measure? Mine looks like its drilled out for a bearing...but I was told that its not.

Bill, you need to eyeball the flywheel end, no other way and it's obvious. There is a hole drilled at the flywheel end and inside it tapers to a point, kind of like an arrowhead. My machinist buddy says Fords and Chevies were the only ones that may or may not have been drilled. Buick, Olds, Pontiac, even Caddy (older Caddy at least) were all drilled. He was the crankshaft grinder at Wyandanch Engine for about 10 years, but he saw pretty few BOP's come through. Mostly Chevy, and most of those had spun bearings. Any shop that balances cranks can drill for the pilot bearing and you might as well get the crank balanced while there anyway.

Wow, that looks like a whole lot more engineering than was needed... I guess it's an option compared to a screw-in plugswitchthing if there isn't provision for one.

Ok so my next question. I have the metal hump to weld on my transmission tunnel. When i go back to install the carpet, does it go over the hump or do i cut it around it. I am going to order the plastic trim, boot and retainer ring, new carpet etc this weekend so i will have the whole factory setup.

 

[Doober]

Can't say for sure because I didn't get the hump when I got my stuff, but personally I'd cut enough to slide it over and trim as necessary.

 

[Bonnewagon]

Here is an example of cutting too much. The reason is that I originally had a hole for the tailhousing-mounted shifter like you will have but then had to relocate the shifter to the factory location. See the blue outline? That's for the hump, I traced that then cut out everything inside the inner lines. The carpet goes around the hump, and there is a plastic trim plate that covers the hump and carpet. The floor is painted with POR-15.

What's the best / easiest way to figure out where to cut the hole?

 

[pontiacgp]

I bolted the transmission up and marked a line on the bottom side of the tunnel

 

[Doober]

The hole I cut for mine wasn't very much bigger than the shifter... could probably trim just enough to bolt the trans in place, then center the hump around the stick while it's in neutral.
