Lunati Cam id for a 429 help

Post  75truck on April 9th 2016, 4:55 pm

I got a Lunati cam with a trade and cannot find the specs on the Lunati site and they cannot find the # in their system.
Lunati Cam SP71 ? N3DT 300-310 Advertized - 110 Lobe Seperation has a purple stripe on the on the
stick.
#1 lobe = 1.460 Base Circle 1.781 x1.7 Rocker Ratio Lift = .545
#2 = 1.480 1.780 x1.7 = .510



Anyone know what this cam might be?

A camshaft with custom chosen lobe profiles ground by LUNATI will NOT be found on their website.

Beside that ... Lunati changed their numbering system when they were bought by Holley and then changed to another after they split from Holley to go out on their own, again.

SO, the age of that cam will also make a large difference.

Sounds about like about the only specs. you are lacking are ICL and .050" duration?

See if you can find a part number on it. I don't know on the customs but, I doubt it will show here. Might have to break down and put it on a cam doctor.

Numbers on the front end of cam

Post  75truck on April 10th 2016, 3:50 pm

These 2 set of numbers were engraved on the front of the cam ,        SP71      N3DT.  Along with the 300-310   110.

So who would have an old catalog?

Thanx,

I have a old Lunati Catalog but like Randy mentioned if it's a custom grind it will not show it in the catalog.
