We’ve been running that combo and a 650 for the last 13 or more years..
Just freshened the 650 three weeks ago with new carbs. Found 16 foot lbs, probably 18 hp or more and it picked up vacume too.
We have a baseline pull 5800 to 7500. All gains show up without pulling to peak..8300.
Can’t wait to bolt those carbs on the 637.

The only reason i am doing this is because i got a hell of a deal on them as I purchased a new dart block with pistons and intake with these heads.Also I got the rocker system with them as well but I do not trust them so I talked with Jesel and they can build me a new system fairly reasonable.

Al Neil??

Nothing in the shop. I have one more source in Berk ca. old buddy who passed -Mike Fujita had a ton of older parts I’ll get with his brother to see if anything is still around. I’m kinda screwed up here, flowed iron bbc heads and jacked the back doing it! Dayum they are heavy in repetition!

I purchased a 4.625 bore bowtie tall deck block that came with a bunch of stuff, like a nitrous plumbed 2x4 tunnel ram and 2 sets of valve covers etc. Guy I got them from in a bulk parts purchase did not know anything about the parts, except somebody else had snapped up the heads, which the guy said they were some kind of Pontiac head.

The serial numbers on the heads indicate they are the 427 pontiac heads and they have pontiac stamped in them.

It my memory is still any good. The Pontiac 10045427 casting has "PONTIAC" cast on the head by the deck.
