Which cam with a Supercharger???

[CarNDrvr]

I have been looking around at changing the cam and/or going to 1.6 roller rockers in my car and have narrowed it down to these 4 choices...what does everyone think? Check out my signature for other engine specs...I want to be emissions compatible as well as see a nice horsepower gain. I am having Ed Wright tune it after the cam is done as well. Here are the cams: COMP CAMS GRIND: Duration @ .050 : .212/.218 Lift : 488/.495 Lift w/ 1.6 rockers : 520/.528 Centerline : 114 degrees Price : $304.14 ZZ4 GRIND: Duration @ .050 : .208/.221 Lift : .474/.510 Lift w/ 1.6 rockers : .505/.544 Centerline : 112 degrees Price : $125.00 ZZ9 GRIND: Duration @ .050 : .212/.226 Lift : .483/.520 Lift w/ 1.6 rockers : .515/.554 Centerline : 112 degrees Price : $325.00 LINGENFELTER GRIND: Duration @ .050 : .215/.220 Lift : .496/.496 Lift w/ 1.6 rockers : .530/.530 Centerline : 114 degrees Price : $279.95 [Modified by CarNDrvr, 7:56 PM 7/10/2002] [Modified by CarNDrvr, 8:06 PM 7/10/2002]

I would definitely stick with 114 LSA to make sure your intake boost doesn't blow right out the exhaust. You also need 12-20 degrees more exhaust duration than intake; the supercharger stuffs it in, but the exhaust really needs help getting out.

CompCams has special turbo/blower cams that work well; their 212/224 would be good for a 350, 218/230 for larger displacements (383+). They should work well with your SuperRam and be emissions friendly- if you don't go nuts with excessive lift. I'd probably stick with 1.5 rockers with these.

I run a custom CompCams grind 215/234 with .485/.510 lift @114LSA on my superchraged 383 and pass IM240 emissions very cleanly. See other specs in my sig...

Very good advise from all the replies, I just have one more to add. Even though your supercharged and forcing the air into the engine, it's still important to know how the heads flow and at what lift, when deciding on the right cam, this is especially important in weather to go with 1.5 or 1.6 ratio. Also if the cam you are currently using needs more help on the exhaust side you might try 1.6's on the exhaust and 1.5's the intake.

I found a cam that has worked very well for me, I am running AFR 190 heads and the engine displaces 383 ci. The cam is made by Crane under the wolverine brand, its a hyd. roller 224/232 @ .50 with .490/.510 lifts and 115 centerline.

8.5 to 1, 7 lbs of boost, 50 lb injectors, mini ram intake. so far 570 rwhp 580 torque.
