I assume the rochester carb and intake are junk
This is not nessasarily true. The intake yes but I have always liked the quadrajets they can be adjusted to run well with all most any combo of mods. They allow you to retune as you evolve thru your mods. if you are going dump all $2500 right off the bat then a holley is a good choice but if you wanted to just replace the intake and the exhaust and swich to HEI you could wake the motor up for about $1000. You do need to find a good quadrajet guy if tou can't tune them yourself. :wink:
