Skip's got it right, just add the fitting to what you have now. I would open up the "slot" so you can move the attachment point up/down to nail down the best geometry. You will still have PLENTY...

The failure rate for cast cranks at or above the 700hp mark is 100 percent!

I tried to use them here WAY back when they first came out. At that time I was using one of the best crank grinders in...

I have had ZERO luck with anything "remanufactured" in China or any starters, alternators, carburetors, distributors, etc from China.

My best advice is to obtain an original SI alternator and...

Couple of things to mention.

IF you install a new SI style alternator make sure that the battery is FULLY charged. If you don't it goes to full charge and works the piss out of the regulator and...

The only big cfm early carburetors are the 1971 HO 455 units (and the 1971 400 4speed), 1971-74 Buick 455's and 1973-74 Super Duty.

Good thing I didn't give them a 1976 or later Olds Q-jet for the testing or they would have been dialing 911 for old Tony!

The unit they used was a 1970-74 style Olds Q-jet. They aren't that...

For sure it acts very "mild" in a 455 HO or Super Duty build. It's the smallest HR cam I'd even look at for one of those engines, even at or close to the "low" stock compression........

It's just a lot easier to forget about using the original distributor gear and also no need whatsoever to run an 80psi oil pump in one.

At least 10 to 1, wouldn't hurt my feelings if it came out a little higher.

I used SD's Old Faithful cam 236/245/112 in my last 455 at 11.3 to 1 compression. It was pretty "tame" at idle making 13.5" vacuum at 750rpm's with only 10 degrees initial timing. Fine on pump gas...

The "old" version of the 60919 cam is a SPC-8 from CMC. Crower simply "juggled" the numbers to make it look like their own cam.

Tey were NOT on a 112LSA, nor were they shorter seat timing.
