360 Build Advice

Guys,

In the market for a new roller cam and rockers for my Magnum 360. The amount of information regarding cam selection is enough to make your head spin and I'm not sure I'm any closer to a decision than I was a month ago!

Car is a street driven, summer driver only that will rarely (if ever) see the track. Want to stay full roller and run 1.6 rockers.

Please find specs below and thanks in advance for everyone's help!

67 Notch (3300lbs w/driver)
Magnum 360 block
MP Aluminum Magnum Heads (mildly ported)
GM 3100 beehive springs, 150lbs closed, max lift .490" (could obviously quickly switch these out if needed)
KB107's zero decked
Eddy RPM Air Gap
3.91 SG with 27" tires (am considering going to a 3.55 SG at some point and to a 25-26" tire in the future so wanted to mention in now)
3000rpm stall (9.5" Dynamic converter)
TTI W2 headers
650cfm Eddy
TF727 freshly rebuilt w/TransGo shift kit and a B&M super cooler

You should have quite a bit of comp for pump gas. Along with street gearing/converter it is not the best combo. I'd go with Bullet [email protected] .560 108lsa installed @ 104-105icl. I doubt you need more exhaust duration for a low RPM street engine with the limitations. Any of the grinds posted are ok,you'd never know the difference without alot of track testing and for a mild street car it is a waste of time to look at too many numbers.
