Street Gear Poll

Let's play a bit. I rehashed the numbers, and if your cam is on 112 and installed at 112, then the ICA is 60* so we're right on the money with a Dcr of 8.64.
Now the next bigger cam is about 262 intake and if ground on a 110, and installed at 110, then the ICA is 61*, so that helps you nothing.
Going to the popular 268* cam; also a 110 and installed at 110, then the ICA comes to 64*, making the Dcr 8.40. Probably not a significant enough change. And if you advance it 4* to the popular install of 106 centerline, that drops the ICA back to 60*, and you're back in the same Dcr of 8.64. So even though you are moving the power up some 600rpm,( give or take), it's not helping you're "ping" one bit.
You may only have three options;
1) reduce your Scr a bit
2) delay or reduce your timing
3) get a much bigger cam, or a custom cam, or run the cam retarded some.
4) get the charge temperature down.
I know I know, that's not three, it's four.
So here's a possible cam; the 268/276, ground on a 114CL installed at 112*. This works out to a Dcr of 8.27. That should do it. That will move the peak power up some 500 to 600 rpm, giving you a bit more power, and,the powerband will be a bit wider, and you may be shifting it around 6200 or more. So springs will be needed.
But heres the thing; you will need some good heads to realize the cam gains.Otherwise you'll just be spending money to "de-ping" your engine, which you can do by retarding the current cam. Oh boy!
