Go to utawesomeperformance.com Marty knows Magnums. I have his UTP 500 cam in my LA 360 with stock magnum heads and this cam pulls really well. Send Marty an email an he'll get in touch with you. You would need a tune with this cam because of the 108 LSA but it's worth it. What I don't like about the Comp and especially the Hughes cam is they have too much lift. Stock magnum heads quit gaining air flow at about .450 lift, anything over that starts causing turbulence. The UTP cam gives you more duration than either of those cams and the tighter LSA improves the lower end torque.
Got a reply from Marty and I guess based on my specs he is recommending a custom grind.
“ I would suggest if you are using stock heads, stay with a 212/212 114 lsa. Keep the lift at 0.456 so you can use stock springs and rockers. If you decide to order that cam from me, I will send you the tune for free in unlimited and any octane you use.”
