512 cu Camshaft thinking

Todays call was to Chris Paget at Bullet cams. Currently out of cores for the wide seperation
However:

Here is his reccomendations
248/254@50
636/636 lift
114 lobe seperation
Springs 230-250 seat and 550 open pressure.
Sounded like he loved the Holley sniper efi

Being that you’re using efi I think that sounds pretty good. I know those systems can be real finicky if they don’t like the cam. Hopefully they can get you one in reasonable time.
