Don Terrill’s Speed-Talk

The single cylinder motocross bikes are making near 2.55hp/ci in race trim. They’re tractable and are abused terribly.

Most of those 9 and 10 second machines will cost you about as much as a hot crate motor and a good transmission for most cars. They’ll also get you around a road course really freaking fast if you have the skills. Then get you to the cafe afterwards. And all under warranty.

F.A.S.T. Racing
Factory Appearing Stock Tire Racing.

The car racing in this series has to appear stock right down to the carb, intake manifold, and exhaust manifold and system. Stock heads and block. And the tires have to be stock as delivered from the factory, no soft rubber, ect.

At first, it was thought that the corvette (L88, ZL1) would be a top performer because of it's superior weight distribution and powerful engines. Not so. Not enough power

The Hemi Road Runner proved to a better performer and was running bottom 10's in the quarter. Hard to believe that a car of that size and tire (G 60 15 fiberglass belted tire) could run that fast.

Then Lane Carey came along with his 1971, SCJ 429 Mustang and ran 9.84/139+. The Mustang has been torn down many times and is legal.
The 429 block that is strong and can be taken out to just under/over 600 cubic inches.
Stock heads that can be valved and ported to flow over 400 CFM's.
A single 4 barrel intake manifold that can be ported to feed the heads.
And a cast exhaust manifold that when ported can handle enough power to handle 139+ MPH in a relatively heavy car.

As many of us here have alluded to, when restricted to stock heads, block, and crank, the 385 series engine (429/460) is hard to beat.

More bench Rac'in talk.
Not going in the weeds yet, "DUDE

Not quite so. When F.A.S.T racing started, the big chevy did dominate. Wayne Nelson was the guy to beat early on, handing it to many of the Hemi racers. He even attended the Mopar Nationals one year and beat the entire field in his blue C3 Corvette.

But time marches on, the class is now very sophisticated and trick. Accessories are machined out of aluminum and then painted to look like (stock) steel. Most gauges and accessories only have a cover on them with the guts removed. I wont even venture a guess what they are doing to bodies and frames to pull weight out.

A really cool racing class.

the gunfight with lots of ammo and thus the argument can go on for ever. I do however, lament
the fact that this argument has moved to the internet. While getting more folks involved, the
loss of traditional venue is an even bigger loss. The traditional venue, of course, is any place
that offers beer [that you buy ] in any volume needed.

In the interest of stirring the pot and keeping the argument going, I would like to add that the
argument of 2 vs 4 valves per cylinder was "settled" back in the olden days when military
aviation was really interested in piston engines. The Air Corps had a long running development
program aimed at maximum HP per cubic inch, which was called the Hyper program, which later
morphed into the Hyper 2 program and was the basis, among other things, for the super-quick
development of the original Chrysler Hemi during WW2. One of the things they found was that
2 valves/cylinder was as good as 4 in selected situations.

If you do, you could send one of your kids to college for a year or 2 for what you will pay for it and redo it. Same with the ford, as far as availability for the trick heads they had. I get it, the ford has a 4.9 bore space and a bigger cam core stock, bot, I didn't say you can't machine the tunnel for a bigger core.
