well i bow down to you guys who run big cams and no compression. takes big kahunas to give up a second in ET (give or take a few tenths).

That's not a very big cam. IMO It's got some duration but not a whole bunch of lift.
I was running low 12.0's with 485/495 & 284 duration with stock pistoned, cast unported 1.88 valve heads, LD4B intake and 750 Holley. Went to KB107 pistons, LD340 with Chuck Nuytenn prepped 750 and consistant low 11.70's. Not a second by a long shot.
Added Hughes stage 1 heads and cam 11.75 true calculated compression, shed a bunch of weight and still haven't gained said second.


big enuff cam for the DYNAMIC cr. i also said give or take a few tenths.
my example: and 8:1 400 bbd went 14.20's. did nothing for the next
season except up the cr to 9.75 and went 13.0's. that was also
with a 230 cam. mpg's went up too. go figure.
but hey... each combo is different. but it all boils down to
the tuner. no need to chase your tail when you dont hafta.
