Choosing a Cam for a 5.9 Swap


Even though it would work better with my 3.23, I want a cam that will work when I upgrade my rear end ratio to a 3.73 or something a little bit higher. I would love to do it right now but one thing at a time for me.

This is the cam I’m running in the wife’s car. Though not a Magnum build, it is a .030-360/zero slug deck w/Pro Maxx CNC ported heads. Backed by a 904 & 3.55 on 26” tires and custom 2400 stall Pro Torque converter.

It is an excellent street performer that drives easy and runs really well for a small cam engine. I think your on track duration wise according to your description above.
(Though, IMO, your way small on the carb size & your tire is a bit large @ 28”.)

THANK YOU! Nice cam.

Yeah, this is the carb that I had in my 318, it is slightly on the small side but hopefully, a spacer will make it useable till I get something a little better. Thank you for the information ill go over your cam card later today to make sure I understand everything.

I’ve got almost the exact setup with the exception of the tires and I’m using a Holley 4777. I chose to go with a regrind from Oregon Cam Grinders, I talked to Ken and he suggested their 722 grind which is on a 112 centerline 222/228 with .494/.512 lift. There’s a noticeable lope at idle and it pulls real hard up top. I have this in a 63 Valiant Signet.

Yeah, im still deciding on the 110 vs 112 LSA but ive been conservative with everything in my car so far so I think ill go a little spicy on the cam. Thanks for the response!

Sounds like a winner to me. I am running a comp cam with the same lift and 210/220 @ .050 and it runs very good. Should work well with your manual transmission.

Good to know! Thank you very much.
