What cam is this? I need specs

I measured .600 lift both int and exh with a 1.7 rocker but I would like to know the rest of the specs.

The cam says a514 then below it says np7074 with a circled M to the side

I'd like to say it's a a 514 cam but the lift doesnt match. I measured with and length of lobe subtracted and then multiply that by rocker ratio which I'm running a 1.7 ratio

A514 CAMS are meant for a 1.73 ratio rocker, they were made by crane

The M-6250-A514 cam and tappet kit features an induction hardened steel mechanical roller cam with the following specs:
Feature Intake Exhaust
Max lift .647" .647"
Duration @ .050" lift 254° 258°
Centerline 107° 117°
Lobe separation 112°
Events @ .050" open 20° BTC 66° BBC
close 54° ABC 12° ATC
Lash -hot .020" .020"
-cold* .014" .014"
Ford Racing CJ aluminum heads, other heads may require a different cold lash spec.

While the cam is mild with regard to spring requirements it does not offer enough exhaust timing.

Some years ago I bought a bunch of the kits. Reground the cams with better lobe profiles and notched the crane non pressure oiled roller lifters. So far very good results.

Imo a 4 degree split is simply not enough for most all of the cylinder head choices we have available to date.

Thanks for the reply. This seems more of street cam to me but would still make decent power with a set of stock the old stock ford Motor sports cj heads. What do you figure the rpm range for this cam is?

This cam will peak in a 514ci @6250rpm .

In a 460ci it will peak @6750rpm.

Hope this helps.

Cheers, Bob
