I was thinking of a 3.50, I like the 3.25 idea, don't know how it would act on the low end.

You probably wouldn't see any difference in track performance between a 3.50 and a 3.25 gear.

Much more enjoyable on long drives with a taller gear, that 571 would easily tug a 2.75 and still tear your head off.

You could put that in the Ohio river & pull barges around with it!
Are we going to see it at Krogers in Milford again before you leave ?

There were a few dozen pulls on it trying all kinds of things but these are the ones where they were happy with a conservative pump gas tune. Ended up with a 2” super sucker on some of the last pulls and the engine loved it.

My father said the dyno sheets showed up.

Thanks for doing that John, much appreciated.

Dang. That's a big motor!

I bet you could put 3.08s out back and it would be plenty fast and an absolute blast to drive on the freeway.

Fully agree.

Here's thread featuring a car that surely weighs in very close to the '69 GTO that is the subject of this thread, running solid 11.40s (best run 11.3893 at 120.63 MPH with a 1.6802 60ft) with 109 less cubes and about 150 less HP using a 3.08 gear:

http://forums.maxperformanceinc.com/...highlight=3.08

I wouldn't hesitate to run a gear somewhere between 3.00 and 3.25 (Ford 9"), leaning towards the taller gears.

No need to spin that big 4.75" stroke excessively while enjoying a long drive, I'd be willing to give up a tenth or two at the track to enjoy a lot of cruising into the sunset during my retirement.

Nice build...for a mostly street cruise car I would be inclined to have continental build a tight enough converter to let the engine idle then couple up quick after idle..
My reasoning is even at 1500 RPM that engine is probably out torqueing most engines at their peak and it wont stay at 1500 RPM very long with that torque.
2.50`s or 2.70`s gear out back, gears multiply torque, how much do ya need at the tires..
These two things would make it seem like a mellow stock car at part throttle and putting around will make the engine last longer and then when the hammer is dropped I would be willing to bet not much would be lost from a 3000 stall and 3.20 gear

Probably hook a lot more street racers telling them you have a 2.50 gear and stock converter If that's your thing

Yeah, I agree I lean toward the 3.25 right now with a tight conv. (better gas mileage too) lol. It came with a 3.23 when it was new.

A little back round,
The 10" continental in the car now is a pretty nice piece, same converter I run in one of mine. It works well for the intended engine it's designed for. It will flash in the 36-3800 range at the track with the previous 455.

The problem now is this new engine is making 200 more HP and TQ than the 455 did and it makes the converter VERY loose feeling. We knew this would happen. He has already talked to Continental about it and they can make a nice driving 10" for it no problem. He just has to decide on his rear gear first because that makes a difference.

If you watch the dyno pulls in post #11, Tony never really pulled the engine down as low as he could have. I think the lowest pull started around 4,000 and you might hear him explain why in that video. What was interesting is that where the pulls started the torque was already on the downward swing at 764 ft lbs and dropping, so we really aren't sure what the max torque was. May have been a little closer to 800. Even so, over 700 ft lbs. throughout the pull up to 53-5400 rpm, and peak HP at 5700, that cracks me up. No need to spin this engine tight.

Hey Paul, I guess you could call it a boat, it's nearly 4,000 lbs with a driver, LOL

When making dyno pulls, it's hard to control the engine when going to full throttle, and start pulling way down low. A trick that can be done to get dyno numbers down low is to make your normal pull up to where you want to pull it, then start increasing the water to load the engine down to whatever RPM you want to go down to. Then it is much easier to control, and you can get numbers down to 2000 or so if you want.

On the receipts the oil pump is listed as a Melling M54F.

No not yet, I need to change the converter, drive shaft and rear end. Coming soon after we get moved.
