RE: You have left out a few things

Hi James
Thanks for the quick reply
I have the edelbrock RPM HYD. cam and I am using a TKO 5 speed std. in a cobra kitcar..relatively light at 2400#'s
3.73 gears

cam specs are.......

Duration at .004 Lift: Intake 296° Exhaust 296° Centerlines
Duration at .050 Lift: Intake 236° Exhaust 236° Lobe Separation: 108°
Lift at Cam: Intake .325 Exhaust .325 Intake Centerline: 103°
Lift at Valve: Intake .572 Exhaust .572
Timing at .050 Lift: Open Close
Intake 15° BTDC 41° ABDC
Exhaust 51° BBDC 5° ATDC

from the Edelbrock site

Heres what I have read in the past...rule of thumb..."never less than 10 deg advance or more than 20."
Also many using the aluminum heads are running much less than the 34-38 total we are used to seeing on the FE.

Good to ask as I am sure there are many out there with similar setups..

Thanks for the advice

Tim

Sorry to say, but both types of floats have their problems. [n/m] -- Mr F, 04/23/2006
