Anybody running this combo? I'm thinking about swithing from me XE cam to the eddie and was wondering how well it worked with the vortec heads.

I ran a similar Crane grind with my home-ported Vortecs. Off-idle launch at the track on drag radials was 12.15/110.5. 0.060"-over 400, 3310 carb, 2800 stall and 4.10 gears. Would have ran in the 11.90's (maybe a bit quicker) with some RPM at launch. I was also over-geared with the 4.10's behind the 400 - a 3.42 would have been better, 4.10 would be better behind a 350.

I liked the cam. Easy on the valvetrain and made great power. I know some guys here will jump all over this type of cam as old-school, but I got great results and would not hesitate to use one again. Here is the cam I used:

Crane Blazer hydraulic
PN: 4003
Grind #: Blazer 294-2H
234/244 .488"/.510"
114 LSA
109 Intake centerline

Hope that is of some help.

If you're going to change cams then why not go to a solid lifter cam?
