Do you know if the cam in the 421 is correct for the year or is it a modern cam?

I think you did a great service to the Goat and to the Pontiac Community for restoring it back to how it would have been the day it was used for the testing in the C&D article.

BTW what size M&H cheater slicks were put on the car? I saw them on another website.
Thanks again for your sharing,

428's still handy, yes.

Current cam. Hydraulic. A custom Scott grind.

Thanks! The Milt stuff is pretty cool, for sure (and fun!), and have retained it all. The car had some rust issues - Scott did some killer metal work - and at that point it just seemed to make sense to return it to the way it was when it (and the Blue Car!) made its mark.

Luckily, a lot of stuff was there, so not much of a parts hunt. And kept much of it the way it was (seat still has a small cigarette burn or two!). Still has the 'ol hairline crack in the passenger side taillight, too!

Heads (not SD when it arrived, but w/ 2.02 intakes) and intake are correctly dated, so may be originals. As Tom mentioned, they'd been cleaned up nicely - and out-flowed a set of Ram Air IV heads on Scott's bench.

Really only needed to score a new block (and headliner, carpets, a driver's side quarter and driver's side floor pan!) - and Tom thankfully came through with the original differential (circa '64 4.33's in place - kept those.). 12-bolt/4.56 spool on the shelf, now.

8.00/8.50 - 14 slicks (I think that may be a Keith pic, btw!). 2" Milt headers.

I was glad that I could return the original 4:33 gear and housing to you Tenney, for the car. It served its purpose under my car and I was careful with the rear-end vs the other ones I blew up as I know the Wanger's axle history. I really enjoyed the short you-tube video, the engine sounds really healthy. The only way a 64 GTO should sound.

Might put a 3.90 back in at some point, Tom. 4.33's buzz the motor a bit on the highway, but they're pretty fun around town.

Credit Scott (Jim/Milt/Mr. DeLorean) for the engine ... Does run pretty well!

Yep, the 3.90s do work better at 70 mph vs the 4.33 gears. Burn some gas with the 4.33 gears and a good engine. I burned 21 gallons going 150 miles Kalamazoo, Mi to Grosse Pointe, Mi one time. 7.1 mpg
