Pontiac vs chevy 350.....any differences?

It just effects the stall speed of the converter to increase torque multiplication.

The tranny shop isn't trying to soak you. I would charge a customer off the street about the same. Time, parts, electricity, shop supplies, employees, insurance, uniforms, yada yada yada...it all adds up... no one works for free. You can probably find a guy local that will do it on the side for you for $400 ish

Sux, Yea, I hadn't really gave those engines any thought, that is odd, you figure in '66 BOP were allready what I call the "normal BOP" & they were making the TH400, why the weird bell housing? Was it left over from prior Caddy engines, say '62-'64? The 425 & even some of the newer 366(?) also shared the same bell as the "normal BOP". How far back do we have to go to find the beginning of the "normal BOP"? Did the '66 Buick 401 have it? Anyone? Lorne

As far as I know, the 429 Caddy was the last revision of the 390 V8 that was used since the mid-50s. The 472 and later 500 was a new engine. Nice motor though. Back then, Caddy was doing different and better engineering it would seem. That 429, now with a rebuilt Rochester 4-Jet, fires up on the first crank every time and runs smooth and quiet. Not bad for an engine that doesn't see regular use and has probably been neglected more than anything else in the past 20 or so years. 340 gross HP, 450 lb-ft of torque and 10.5:1 compression too.
