Street Cam Suggestions for a 340?

I'd run something like a Voodoo 60403 (old number) or XE268H. You'd need to get the initial timing tune up right and it will not lack low end power.

375 is more HP than either of those cams will provide with a stock intake port. If it made 325 with those exhaust manifolds, you'd be lucky. I have a 340 with a mopar 508 hyd cam. With the stock 68-70 hipo 340 manifolds, it would stop dead at 5100rpm. Installed headers, no other changes, it pulls hard to 6000. The stock manifolds stink... :)
