Dan;

Thanks. As soon as I get the results sorted out and posted on my site I'll post it in this thread.

Jeff;

Ssssshhh....that's a speed secret

Bruce;

No luck...it's gone on into that great video file in the (cyber)sky.

Just a brief gloss-over on the engine--it was built to resemble a stock L78/LS6 in appearance. It does have an aftermarket rotating assembly, but the only non-OEM parts in it that can be considered "power producers" are the longer stroke (4.25") and a surprisingly docile solid lifter cam. The heads have absolutely NO portwork or any other "tricks" done to them, and even still retain their measley 1.72" exhaust valves. The intake is a stock 163 provided by none other than our own WILMASBOYL78, and the only thing it's had done was milling out the plenum divider. The rest of the engine is painfully stock.

You'll just have to wait `till next week for the rest.

Oh, one last thing; they dyno facility I use is equipped with an older Heenan & Froude dyno that is very, very conservative, or in the owners own words, "stingy"...which is just the way I like it. As such, don't expect to see some bogus, fluffed-up "west coast magazine"-type dyno numbers from anything I build & dyno. These are honest, real-world numbers.

I'm still waiting on my dyno sheets.

I'm told I should have them in a day or two.

Are they still using those slow old dot-matrix printers?...

[VintageMusclecar]

This dyno doesn't have the modern software that spits out a nice tidy dyno sheet with all the amth already done for you, much of it (like brake specific fuel consumption numbers) has to be calculated seperately, which is then written down by hand. Not exactly convenient, but it works.

I'm getting impatient too!
