My 496 project, the dyno results are in
 

Finally got the engine wrapped up and on the dyno, made the last pull wednesday morning.

I'll have the dyno sheets sometime next week, and I'll have all the info condensed and on my webpage a.s.a.p. There is some very useful info to be shared which I think you should find quite interesting, if not surprising.

Oh, btw...I HAD a video of the engine making a pull on the dyno, but for some mysterious reason, my piece of ^&$^#&*@*@^&^$%& Sony camcorder deleted it while I was loading it onto my computer. To say I was furious would be a bit of an understatement. https://www.yenko.net/ubbthreads/imag...emlins/mad.gif https://www.yenko.net/ubbthreads/imag...emlins/mad.gif https://www.yenko.net/ubbthreads/imag...emlins/mad.gif

More later.

Why, I did, of course...both of them. https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

I started with a "correct" `67 L78 carb (LIST 3910) to start, then switched to a `67 L88 Corvette carb (LIST 3418).

Psssst, your headers are on backwards! https://www.yenko.net/ubbthreads/imag...lins/smirk.gif Can't wait to see the dyno results. That suks losing the video of it though.

Eric, Cool!

BTW...check your computer over again. I had the same thing happen with my Sony camcorder...where it said it deleted the video...but I found it by searching the newest added files first... https://www.yenko.net/ubbthreads/imag...mlins/hmmm.gif

Dan;

Thanks. As soon as I get the results sorted out and posted on my site I'll post it in this thread. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

Jeff;

Ssssshhh....that's a speed secret https://www.yenko.net/ubbthreads/imag...ns/naughty.gif https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

No luck...it's gone on into that great video file in the (cyber)sky. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

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.
