    You guys should talk to a guy named BISHOP on here. He has a Cadillac 429 (running) and TH400 for it. One of you gets the motor, one gets the ****** if you go halfsies on it.

    I plugged off the heatriser in my intake then put on an adapter plate and a 625 Street Demon.. Switched from points to a pertronix kit... Some say points are just as good as long as your not revving the hell out of it.. But with a 429 there's no reason to rev it too high... And the only intake I have found are the ones on lakeheaders.com. Was told today that the earlier caddy intakes may have the same port position what not of our 429's... Just gotta get an older intake and take some measurements....

    429 Caddy takes the same trans as a Nailhead Buick. A 64 429 should have a ST 400 behind it stock.
