428 CJ Dyno Results....Inquiring Minds...

[Whaler]

Hi Clois
Thanks for posting the results of the testing

Questions......

Are you using a windage tray?
Are you using a march pulley setup? Underdriven stuff is what I am getting at

What was your initial/original air breather for these runs?

I have really about the same engine except went with the RPM cam as put in the RPM edelbrock package. Opted out on their edelbrock carb and went with Holley 850 w/mechanical secondaries. Also a little different, I have the MSD 8 mm wires and am using accel 416 plugs gapped at .40

As I had asked before, I was really curious about your initial timing and advance set-ups for the MSD. I have yet to go there and do this fooling around so this is very helpful info for me

I know also on my car, that my builder made up a new sidepipe design and that when he tested it he got considerably more HP out of it over the old ones he was building for his cars. He claimed 40-60 HP

I know what you mean when you talk about fords original HP claims....345 HP on the std 428 . They also say they were kept down conservatively as well.

Keep us posted
