Got my engine back from the machine shop late this afternoon.
He checked everything out to see if it needed balancing and said it did not.

I also finally got the specs on my camshaft. Turns out it's an old grind that's not in the Isky Cams system anymore:

.485 valve lift both intake and exhaust
.050 duration is .244 for both intake and exhaust
108 Lobe Center
2000-7000 RPM range

Your cam specs are pretty close to what I put in my fifth GTX. Car had a Hemi grind purple shaft when I bought it. I liked the replacement better, worked well on the street with an otherwise stock engine. I saw your car has manual brakes, so the 108 lobe center won't pose a vacuum issue.

Thanks. The guy doing the engine work also thought the Isky camshaft would be good for my car, and he mentioned the purple camshaft as well.

The block had been painted black, orange and blue so it needed to get cleaned up and ready for Epoxy Primer and paint. Noticed that it has a Mellings High Volume Oil Pump on it also.
