what is the converter rated too? example: ( 2000-2400 ) if you can get it to leave from an idle and get a decent 60 ft it may run 12.50s i would shift at 6000 rpms at least it has gear so it will keep it in the meat of the cam but im sure someone in here will disagree as well

my .02 is that it will run 13.50 to 13.80's, the cam you have with the rpm range of 2200-6400 is probably speced in a 350 chevy so in your 327 it will act bigger, cause of the less stroke in the 327, more than likely in the range of 2400-6600 or there abouts

you will need at least a 2600-3000 converter with that cam

Speaking from experience, and depending on your elevation, it will take a 4.88 gear and looser converter (or nitrous) to get you into the 12's. My brother used to run a 327 with the same heads, etc. and the only way we could get it to work well was to use the 4.88 and looser converter.

This is just based on our experience. Also, we race at a higher elevation (track elevation is 2700').

I think all you guys are optomistic ! i see a 14.0-14.40 , my reasoning is the intake ,stall,vehicle weight,gears,cam & cubic inch . This combo doesnt really look like it will do any better than a 2.2 60ft . especially with street tires.
good luck , and keep us informed !
