I'd have to look it up but, the mains and rods were about 2.375 x 2.0 and the stroke was 2.84.

How much run-time did those engines typically receive before the crank was replaced?

In my research, it wasn't stated.

A successful 180°, V8 engine, was designed over 80 years ago, the Novi. It ran at Indy, for 23 years, with only three engine related failures. Magneto, one broken crank and one piston. Excellent record, I would say. It was a 181 CID engine, three main bearings, with a large centrifugal, crank drive...

Back to the additive question...........

Toluene seems to be the cheapest, safest most commonly available additive. It is a common paint thinner, found in all paint and hardware stores. Are there any formulas for the amount that it takes to increase the octane number?

I'm not positive of the date but, it was either late '68 or early '69. I bought a MT Cross Ram manifold for my 427 FE. The manifold was used but, I bought a pair of 3310's new for it @ $35 each. It seemed that the market was flush, with 3310's at that time. In today's money, it would be $265, the ma...

I would agree but, for the FLAT front end!

Ford seemed to go all out on the cam side of the valve train, Besides the "Rev Kit" they kept lightening the lifter. What interested me, was the .06 lifter offset and the 150" radius of the mushroom lifter, using a 3' (.05°) taper on the lobe. Apparently for a vibration issue. I'd be interested in w...

Thank you, Michael. That is excellent!!!

Thank you, Andrew.

I'm a retired machine shop owner and I was a sub-contractor, for Erickson Air Crane. I made thousands of parts for the Sikorsky S-64, heavy lift helicopter, including Ericksons, first retardant tank, in '91. To begin with 7075 has almost exactly twice the yield strength of 6061, both in T6. In gener...

There are locating pins, on the leaf springs, that go into the holes on the mounting pads, of the axles. They can shear and cause that. It happened to my 65 1/2 K-code Mustang. It's a quick fix but, driving it, you can't usually tell. The steering wheel, will give you a clue though. If you know abou...

Up date:
I forget to get back to this thread. I took the car to the NHRA inspection, on the 19th of March and the inspector, WILL certify it for 10.00 with a roll bar.

Geoff, what makes you think the frame is bent?

I an not remember when I last saw a 409 and very rarely a 348. So, regarding demand, I doubt that there is enough for any new products.

Other than that, all I have to say is, have fun with "Your four speed, dual-quad, positraction four-oh-nine." and "Giddy up, giddy up, giddy up 409"

Mild? 10 - 12 lb boost?

I would agree with with a 180 manifold, you don't get much boost below mid range. A 7121 or Air Gap.
