Cam choice?..

If it's not going to see above 3500 rpms, I'd leave the stock cam in it. Put a new timing set in it, work with the curve in the distributor. JMO
No I don't see it going to thirty-five hundred RPMs for any reason.
I was more looking to breathe a little life into it make it sound good and look good.. give it a little Rumble make it sound like it's got something going on maybe.. what it looks good sounds good and runs good it seems to sell a little easier...?..
Trust me I would rather not spend the money.
