Sorry for the Delay, It took him a few days to get back out to his shop (garage).
The cam that he had installed is a Lunati Voodoo cam grind number VD-PV8-276,
specs are .504I/.527E lift,
233I/241E duration @.050.
He did not change the springs out from the Edelbrock ones (Don't know why he has the Lunati ones for this cam).
Next question is how do the Edelbrock springs compare to the Lunati ones for this cam? (Lunati spring p/n 73949LUN, Spring Type:
Dual w/damper, Outside Diameter: 1.440 in.
Seat Load: 120 lbs @ 1.650 in.
Open Load: 265 lbs @ 1.250 in.
Coil Bind: 0.950 in.
Spring Rate: 363 lbs/in.)
He wants to switch to this Comp Cam HydRoller: XR288HR
236I/242E duration @ .050
And it calls for these springs
O.D. of Outer Dia. 1, 1.437
I.D. of Outer Dia. 2, 1.073
I.D. of Outer Dia. 3, .697
Seat Load 115 @ 1.700
Open Load [email protected]
Coil Bind 1.020
Rate (Lbs./In.) 402
Will the Edelbrock springs work or should he change them out?
Thanks for your patience and help!
