My last cam was a custom grind (Clay Smith IIRC) that I ordered from J Mummert. Properly machined for the oil groove, and came with the sheet from the Cam Dr. Well worth the effort of catching up with him, getting his opinion, and knowing it's right.

Try John Mummert first.. If he can't help, a stroll through the various cam catalogs should find a cam close to those specs..

Thanks for all the responses. So where would you source the cam with those specs? Love the knowledge around here. Thanks

Mike, still lovin his 57 t'bird after 53 years!

Duration @ .020 not helpful.

That is the cam I would use.. It's about perfect for a blown hot street engine

The blower cam that Mummert produced in the early 2000s is 226 @ .050, 274 adv and 112 sep.  It is a copy of the Ford cam, from what I understood at the time.  I think this is what Frank runs in his F-code.

The cam card is for the Isky 301 but it is a special grind that I will be using in my blown Y block. Same grind that "Moonshadow" is using in his motor.

According to Isky's website, your cam card specs are not for the 301300 cam. The 301300 has an advertised duration of 286/with duration @ .050 250, and the LSA is 108. RPM range is 3000-6000. I would not use that cam on anything but a normally aspirated race engine.

So the 301300 Isky Cam Card I have (thanks to Moonshadow and Ted) indicates a 110 degree lobe center, but Intake Timing Duration of 264 and a Exhaust timing duration of 272. So is this  the major modification from the stock Isky 301300 grind?

Hopefully, you are going to use 5750-471 cylinder heads/w 82cc combustion chambers.
