340 cam help

Not sure how racy you really want to be versus the street, so I removed my original thoughts.

I don't know whether you'll be running more 1/8th or 1/4mi, but while the low gear will give you 60' times, just remember to cam or converter for that rpm drop into 2nd. A tight LSA will give better torque in that range, probably in the 3500/4000 area depending on your shift point.

Keep in mind also, are the valve guides already machined for dual springs? If not you'll definitely have to address that, as any cam in that range will require it.
