Default Dyno Wednesday, guesses?

Hi all,

Taking my 498 to the dyno. It is a Stuska / DEPAC engine dyno.

Have a few tests to do, going to test as is, to check the drive train (and accessories) losses, as it made 512 HP on a mustang chassis dyno.

I am running 1 7/8 headers and have a set of 2" primary's to try.

Also I bought Brian Rocks old cam 263/269 at .050 on a 108lsa, with about .700 lift, so we are going to stick that cam in after to take advantage of the heads a little better, it will be interesting to see how the tripower keeps up.

Heads are 72cc, 2.19 intake valve and 1.77 exhaust. pistons are dished for 10.8 compression. Distributor is MSD ready to run.

Most of the info is in my signature, I am running 1.65 Harland sharps, that measure 1.69 with my valve springs.

So what do you think it will make? Two numbers, one for each cam.



Update you all wednesday!!
