Looking at adding a mild/medium Crane Comp Cam ( no more than .470 lift) to my car below so stay with stock heads and rockers, springs.... While I am at it, we will probably port the intake runners/plenum and do a little porting to the heads.

I am hoping for very low 13s.

Is there anything else I can do to get a big improvement and into the 12s, I drive it everyday to work, I do not want anything radical and I do not want to send alot of money like new heads, and no blower or nitrous.

I was thinking of of a torque converter down the road, instead of going to 3.70 gears, I seem to hear mixed reactions on that one.

Will my stock chip be fine?

Thanks.
