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.

Wow, Nice combination...Thanks for posting.. I want one..

What oil pump did you use.

Thanks John for the dyno sheets..

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

[chuckies76ta]

Thanks... have you done any 1/4 mile testing yet?

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

Very cool car

What did you use for exhaust ?

[Formulajones]

On the dyno they used the headers for the car along with mufflers on the dyno for a more realistic number.

On the car it's the same 2" Hooker super comps. The 3 1/2" collectors go into 3 1/2" pipes, into a Dr. Gas "X" pipe. The X pipe is 3 1/2" inlet and 3" outlets. So the Dr. Gas "X" pipe exits with 3" and into a set of (they are called) race mufflers. The name of the mufflers escapes me but I do know they are not in business anymore. They are regular looking case style mufflers. From there a set of Torque Tech 3" tailpipes.

Sounded pretty quiet in your video

[Formulajones]

Yep, considering the size of the system it has a very tolerable sound level. No drone in the car and pleasant to drive. It does make some noise when behind the car and standing on the pedal. The mufflers do an excellent job for a race muffler. I'll have to do some digging and see if I can come up with the name. That system has been on the car for years, and before that was on a 10 second buick. So it's been a good 15-20 years since those mufflers were produced.

Here's a video with more pictures than posted. This was done quickly last night, my wife still has to do some editing.

awesome

[Formulajones]

Just your average pump gas street car running today with open headers.

nice job!

Nice!

New Continental converter is in the car now. Happy to say it drives fairly snug, or what I would consider a normal stall converter should do. Definitely feel and hear the trans shift now, and cruise rpm dropped about 600 rpm. Instead of 55 mph at 2800 it cruises at 65 mph at 2800, with just a converter change, so the old 10" Continental that was perfect for the 455 was driving a tad loose with this engine.

Continental built another 10". We had plans to drop the gear to 3.25's but Continental couldn't tighten the converter enough to work with that gear behind this engine, and it was recommended that a minimum 3.50 gear be used. So the new rearend is getting ordered with 3.50's. Also swaped the 295 drag radials for a set of 275's, 2 inches shorter.

Getting close, It's almost ready for a track outing.

I run a 3.70 gear and 275 tire behind my 565. Wish I woulda did the 3.50 instead. Plenty of torque to handle a higher gear.

[Steve C.]

With this monster what tires are behind run on the street ?

.

[Formulajones]

We run MT drag radials on the car at all times. With the expected 3.50 gear coming I talked him into knocking the tire down to a 275. (was 3.73 with 295's)
Actually fits better and allowed me to set the rear suspension back down and get a better handle on instant center. We found it was simply hitting the tires too hard now with this new engine so I moved instant center out, made a few other tweaks.
Made a couple of bonsai runs on the street and even on a dusty road without heat in the tires the car works pretty damn good. Hooks without too much trouble and isn't doing anything unpredictable. This car has always transferred weight very well and does a nice job of planting the rear tires. It's amazed me at how well it's working on the street with very few chassis changes given the big change in power. I'm really curious what the new 60 foot times will be.
