The only reason I mention them is because I have no desire to go any combination of stroker so PLEASE don't even bring it up. I also don't want to spend money on a RETRO anything or increasing valve sizes. The stock heads will be ported and get a good valve job. Also I have some good roller tip 1.6 rockers I'll be using and a Eddy performer intake. (not an rpm. I know, but it was a freebie) Can someone fill in the blanks for a good flat tappet cam, carb and piston. Any help is greatly appreciated.

i think much of the combo would depend on what the heads end up flowing. flat top piston will give you little less then 11-1 compression if the heads will support that with the flow, otherwise dish setup would probably be around 9-1, so you need to know which one before you get the cam which would also hinge on the chamber size in the heads. sounds like a everyday driver type street motor? i would use a carb in the 650 range unless you are really good and can setup a larger carb and feel lucky, you might need something with the vacuum ports or pcv openings also. i went down to auto parts store and bought a 600 cfm holley for about $250 for my crate 351 and have been happy with the driveability, but when i go to the track i can switch out to a 750 also. the 600 is better for the mpg also.
