Default Lunati SR 60133 too big for street 383?

http://www.lunatipower.com/Product.aspx?id=1994&gid=290


Putting new heads on my 383 and was thinking of going to this cam. How would the drivabilty be? 68 camaro 3200lbs, T56 trans and 3:73 12 bolt.

Engine combo.

383 10.8 CR
AFR 210 el
Dr. J ported air gap
Pro systems custom carb
1 3/4 headers, 3"x, 3" borla xr-1
Full MSD ignition

I have manual brakes too. This is a weekend toy. Just looking for a hot street setup.

With the added CI's where would my power band be?

Driveability will be fine. That's not that big of a solid roller. Run it.

That cam is about perfect for a street 383. If you have them
custom grind it with a 106lsa and a 102icl it will make considerably
more power.

No It's not too big for a 383, my 383 is almost exactly like yours and has a ton of torque. The cam I have is almost identical from Comp and is still in my engine. The 3450lb car ran 10.82@127mph on it's second outing untuned on the stock EFI pcm, so now I decided to go with a Fast engine management and turn 7400rpms and I would like to sell it if you are interested.. the duration250 is 248/254 110L/S, 670lift on both, it's the best cam fior peak power under7krpms but since I would like to turn 7400rpms, I want to add 10degress of duration to it and maybe closer to 700lift. LMK if youre interested. later

I think Lunati grinds their cams with 4 degrees advance already. Would you still suggest a 106 lsa?

I may go with the 60132, 243/249 and have them grind to a 108 lsa. Should still pull to 7000 and have awesome midrage tq!
