Butch, the carb came off of a 1957 Pontiac 347 that was being parted out at Pearson’s Junk Yard. I’m pretty sure it was a AFB.
I remember he almost bought that Hydramatic Transmission, (remember that beast), but Pearson had several manual four speeds that would bolt right up. Back then Morgan Clutches were the hot ticket.
The second engine he built, which I helped with, was a bored out 283 out of a ‘57 4-door. He used the same 30-30 cam, but scored a set of “power pack” heads that Tommy Thacker had ported. He had a duel carb manifold with two WCFB’s on top. Tommy, who had a distributor machine, set up a cast iron body duel point for it.
This was back when we called a 1/8 bored 283 a “301”. By then he had stripped the old ‘48 Fleetline down to nothing, added some traction bars, and Atlas Bucrons on the rear. We made a set of 8 inch rims by chucking up 4 rims and parting out the halves so you had 4 long sides. Weld them together and bingo, 8 inch rims.
That 301 was a real screamer. We learned all about valve float. Isky springs, (I think), cured that.
Those were the days of real hot rodding. 13 to 1 compression, Gulf Crest gasoline. Junk yards were a treasure trove for parts that you visited for the fun of it.
His next engine was going to be a 409. But he got drafted.
