ISKY Cam..???
My Cam search now brings me to the Isky Cam. http://www.iskycams.com/makesearch.p...&engine_id=310
My axle ratio is 3.07, but the cam I'm looking at.....Part#: 261257/265
grind no. /type rr-257/265 hydraulic roller application excellent performance cam with good vacuum good idle. 3.08-3.73 axle ratio. 9.5:1 comr. up to 650 cfm carb. computer compatible. stock converter rpm range 1400-5600. valve lift .465 .485 valve lash h
Question 1.....Will the .01 difference in the axle ratio matter/is my ratio to low (I dont see how) ???
Question 2.....If I decided to up my axle ratio for a larger cam who would you recommend???
thanks......

That is kinda what I do only its just the exhaust. Here in Va we have private garages that do the inspection for the state. I have a set of the factory exhaust cut to fit the headers, then I added cheap bullet cats where the resonator used to be. It passes the sniffer test with no problems. But I do have to switch every 2 years.

I read-up on it late last night, sounds good.... Still, I would like the cam to kick-in at a lower RPM. From what I can tell it really doesnt come on until 3k. was hoping to find one that kicked in around 2k. Of course I would change my rear-end from 3.07 to 3.73 since it's an auto.
