My "bad" on the '68 vs. '69. I SAW "9" , but READ "8"... 62s ARE '69 350 HP 400 heads with auto trans (48s w/manual). Good heads for a mild street build.

The physical description of the car certainly "sounds" '69 (tail light/bumper comment). Even better! No "His and Her's", though. The '69 has the good factory "ratchet" shifter. Pull it into "manual low", hold it to the right while shifting, and get only one gear at a time (no neutral mistakes).

The "downside" to the 350 HP engine is the 10.5:1 static compression. Too high, WILL detonate on 93 octane. "Dish" the pistons 3 1 /2" diameter, .100" deep. 9:1, good to go. How "far" do you want to take it for power?

The carb is the "correct" carb for a 350 HP 400 w/auto trans, '69. Plenty of good Q-Jet "knowledge" around, so no need for anything else unless you're going MUCH "faster". I can point you to a couple Q-Jet specialists.

I can also point you to the good Pontiac "supply houses". The resto people that sell all brands, MAY send you Chevelle parts 'cuz they "fit". Ames or Performance Years deal STRICTLY with Pontiacs.
