Cam depends a lot on if you have an auto or a manual with that gear ratio...
What we'd really need to pick a cam is full specs on the engine. Get in touch
with the previous owner and try and figure out what you've got. Then let us
know and we can help more. In general, though, with a manual, my 74 TA
400/4spd is "drivable" with a Comp. 292h cam, lots of head work (4x), headers,
stock rockers and shitty carb, but doesn't idle for shit and fouls the plugs if
you don't let it run on a regular basis. I'm thinking a single plane intake
and fuel injection will solve my issues and want to go full roller rockers
while I'm at it. It will slide you up the back of the seat through first and
second gear if you keep it above 2500 rpm, as it is. But with an auto, you'll
also need to work with converters and all that... Like I said, need more info
on what you've got and what you want to use it for. I'd definitely stick with
stock ratio on the rockers. You're better off since you sound like you might
want a cam change, anyway. You might want to consider moving down to 3.73s in
the rear as well, unless you're just racing.
