Here's my set up.
360sb running 13.2-1 compression
procomp 210 heads with manly componets and light porting
Hurrican high rise single plane with holley 750vs on top.
3:73 rear with 26" tires.
headman full lengths through 3in purple hornies.
3600 stall converter th350
Right now pretty much have the same set up and was running summit .510 .533 cam with 9.2cr but wiped a lobe. heres what im looking at for a new cam. what do you guys think

That cam likes a lot of rpm. Will want a 5500stall 8" converter and 4.56+ gearing and a larger DP 800+cfm carb.

If you want to stay with your present carb, converter and gear, use isky cam #201549. Install on a advanced 99° to 102° intake C/L

Ok. I'm going to upgrade the carb but Is it possible to get away with the 3600 stall?
I also have a 200hp plate system on top.
Im running 1.6 rockers righ now to will the cam perform as good with those. I know my heads like high lift and will take .600 right now..

You can use that converter but you won't get the full potential of the camshaft with such a low stall speed.

Chances are it will be a poor cam choice for the rest of the car.
Not enough stall speed
Not enough gear
Tires too small
Not enough carb

Using 1.6 rockers may push the limits of your heads and valve springs. The 1.6 rockers will put the lift just under .600. As long as the bottom of the spring retainers are not hitting the tops of the valve guides and the valve springs have at least .060" clearance at full lift, it may be fine.

There's also a piston to valve clearance that needs to be checked. That's a lot of duration and cause interference problems if the pistons don't have huge valve reliefs.

Isky 201065
All out competition/drags. 5000 Stall. 5:13-5:57 axle ratio. 850+CFM Carb. 12:1 compr. RPM-Range (4000-8000) Valve Lift (.560 .560) Valve Lash hot (.028 .028) ADV Duration (314 314) .050 Duration (272 272) LC 108

That's an all out racing camshaft. Forget about any kind of street driving.

Thats what Im lookin for...
My pistions are domed and do have good valve releifs. But I will be chcking.
Thanks stephen 87 for the valve sping cleanence Thats a great help.

Also would cam isky cam #201549. Install on a advanced 99° to 102° intake C/L Serve me better..
I want to be in the 10's for sure. The only time the cars on the road is testing.

F-BIRD'88

How the ^%$# are we supposed to know if you car will run 10's.!!!!!
Is it farther to Cleveland? or by bus???

If it runs 12's now don't expect a cam change by itself to pick up 200 horsepower.
You need 600 to 650 horsepower to run 10's in a 3200-3600# car.
More, if you can;t put it to the ground.

The Isky #201549 cam makes very good power in a motor like yours with a 3500 stall. (i've made well over 500hp N/A in a 13:1 350 and near that in a 10:1 350. with this cam {but not with Pro Comp heads} Works even better with a 5000stall.
Works real good with nitrous too. Good dual purpose cam for your car.
A big, big step up from the generic Hyd cam you have now.
The (intake) valve to piston clearance with the 201549 cam will be very close.
You must check it. Needs the right valve springs too.
This is no wimp cam. But don;t expect it to function with junk springs.

The bigger isky cam will definatly require piston notching.

The bigger isky definatly needs a 5500-6000 stall converter and much more rpm and gear ratio.
Don;t get all wrapped up in rocker ratio or peak valve lift.
Swapping rocker ratio has a very mild effect on power.
Higher rocker ratio usually lowers the top rev limit of the valvetrain.
If you exceed the ability of the springs to control the valvetrain at high rpm,
the engine will make less power (and soon come unglued)
I recomend 1.5:1 rockers and the Isky #201549 cam.

What times are you getting now? et 60ft MPH etc???

Redlinerevver

If I change to 1.5:1 rockers and the Isky #201549 cam will I still have any problems with valve clearence? Im going to a 850dp carb and changing tire size and gear to prob 4.56.
Right now im around 12.50's w/o nitrus 60ft times suck b/c tires
But with the generic cam and 9.5 cr. The cams junk.
I Know procomp heads flow good around .600 lift and I will end up chaging springs. I know the heads have a bad rap but I think there awsome for the money. They do make power.

It's hard to guss what the car will run but Please help me get me set up with a possible combo to do it.
