I am looking at changing the cam in my Chevy 302.
This is what I have 11:1 comp AFR 210 Race ready heads victor Jr. with a 1" open hole spacer, a 825 double pumper Demon carb.
The Cam I have in it right now is a Comp Cam XR292R it has a lift of .582 intake .588 exhaust. Duration at .050 is intake 254 exhaust 260 with a LCA of 110.
What would be a great change or is this the right one?
Thanks :)

Gotta love sticks! You want to turn that thing a little harder?

What are the rockers and springs? Old AFRs or are they new ones?

that cam is a street roller,incorporating gentle lobes for longevity.i have used it before in a few applications and it works well.one thing i might try is upping the rocker ratio,1.6's work well,increasing the lift and adding a couple of degrees of duration as well.im wondering if your short block is able to handle a higher shift point,thus a cam change would be beneficial to you.with your cubes and your cylinder head configuration,its possible to make power to 7500.with your present cam,you are leaving alot on the table.

The nice thing about the SBF is the cam diameter is big so you can still get some big lift with it with 1.5's. Hell we can go .700" lift and turn that thing some real RPM and let it eat. If you want something look me up, shouldn't be too hard.

A perfect camshaft for your engine would be this following Crane Cams and will make port around 7500rpm and make great torque combined with your gear and 4 speed transmission.

You will need good spring pressure, more than you have, My suggestion is 280 seat and 650 open

290/306 @.020"
260/268 @.050"
.670"/.625"
106 lobe seperation angle

By the way if you prefer Comp Cams, I would go with the following Comp Cams cam

Intake Lobe Number 2226
289 @.020"
260 @.050"
183 @.200"
.442" lobe lift

Exhaust Lobe Number 4264
301 @.020"
268 @.050"
182 @.200"
.432" lobe lift

Have the above camshaft ground on a 106 lobe seperation

By the way I did not post full specs on the Crane Camshaft above
290/306 @.020"
269/268 @.050"
184/183 @.200"
.670"/625" lift
106 lobe seperation angle

This is also in a street car! So I don't know if I want to go too crazy with spring pressure. When I plug the present cam spec. into Desk Top Dyno it seam too make the most HP with this cam?
Thank you all for you in put :)

You and these HXL's.... it's a street motor and he needs the stuff to survive (springs, lifters)

The exhaust is a nice tame pick but that intake is not going to keep the deal cost effecitve in the long run.
