Cam Question for 455 SUM2801 or 2802
« on: June 01, 2017, 01:56:45 PM »
Not to start a cam war here, but have a specific questions about 2 different scenarios regarding the summit cams in a street car.

Currently have a 455 in my 68 Firebird. 7K3 heads around 9:1 CR. Headers, Perf RPM Intake, 800 cfm carb, 3.55 gears. TH400 w/ stock converter.

Eventually will have 9.5:1 CR, ported heads and a TKO manual trans. But life is real and not sure when I'll get around to this.

So my question is, in reference to the Summit cams is this:

Assuming the 2802 is an appropriate cam for the eventual configuration, will the motor be best suited for the 2801 initially and then upgrade to the 2802 when the other work is done, or is it close enough that I'll be able to drive on the street with the 2802 in the current config and just get the additional benefit with the rest of the mods.

Thanks in advance.

The 2801 is too small for the 455 at that compression ratio, use the 2802 cam.....Cliff
