i just had a 565ci built with bb2 heads ( with ton of hand port work) i have a victor 454-r matched..15 to 1 compression..
my engine guy said my 565ci will have more torque with the heads and intake i used..this was OK with me since i run the 1/8...TQ IS kING in 1/8th...
i used this victor cause i had it matched to the heads already plus it has a ton of Plentum work done.... i have heard GREAT things about the Profiler..but some say its for bigger engines 600+ci or if your running an exotic head on your 565ci like a 12 degree profiler etc...I DUNNO :?: ..I know what their web-site says
Just curious..what does your Mustang weigh ?..My camaro (3100lbs) with a 12 to 1 compression 511 ci ran mid 5.90's in 1/8.. which should be in the lower 9.60's in 1/4...
with this new 565ci if i do not run 5.60's in the 1/8 and 9.20 range in 1/4 i will be disapointed. ( all motor )
Curtis can tell you a little more on this subject i would bet.
