The bones don't look too bad. Those Ferrari Testa Rossa style side gills are pretty incongruous.
Thanks for sharing the progress here.

I realize haven't posted much here on the progress. Frame was powder coated but I am not 100% happy with the results so not posting those photos yet. Suspension - ran into a bit of a snafu after finding one of the upper front control arms was bent to the point I decided to find another control arm to properly press bushings. Being a B body, I was surprised that the upper control arms are not more robust than A Bodies. There is other progress and will post more shortly.

The original YK - 9786135 engine bottom half redone with "zero decked" block, .040 over with Racetec forged pistons, Howard forged I beam rods, ARP studs, factory steel crank, and Howard's Cam. I insisted on sourcing as much as possible to be US made.

ah, the old in ground hydraulic lift!
Those were neat to use, especially the twin piston you have. |

Frame Redone
Hooray, frame came back from new powder coating and looks a million times better (different shop did the work this time :-). Finally some progress.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
