Finally got back around to this project. Getting ready to drop the 512 back into my street car. I haven't touched this project in a long time. The car has a thick coating of dust on it!

Nice! Is that going in the Coronet I've seen a few pics of? Is that a Doug Nash tranny?

Sweet tell us more about the combo. Are you going to run the manifolds too?

Re: 512 on the hook - 04/18/10 06:55 PM

Yep, manifolds are a must for me. 512 inch low deck with RB mains, cross bolted main caps, roller bearing camshaft. CNC ported Mopar 452 heads. Callies crank, Crower rods, custom Diamond pistons. Tons of custom stuff, the dang project took me about 5 years. I think the guys at CRE machined this block back in 2005.

Another view of the motor from the top before it goes into the car.

Close up of the head pipe on the driver's side. It has to snake around the bellhousing, starter and clutch linkage. Nobody makes 3 inch pipes that work so it all had to be built by hand.

Oil pump cover is custom made to clear the K frame.

Here is the rotating assembly. Callies crank with 440 mains, Crower rods and Diamond pistons. The big dish gets the compression down for pump gas.

Roller bearing camshaft. This wasn't one of my better ideas!

Yep, Doug Nash five speed.

Yes, it is going in the Coronet as soon as I clean away the clutter in the shop.

Looks tough Andy now get that thing in the car and grab some gears.
Do you have a 3.27 low in that Nash box? My Richmond has the 3.27 and it works well with the 3.54 rear gear.

Doesn't take too long to drop it in the car. Hooking it all up does take a little wrenching though.

Looking awesome as always Andy. I'd love to know the number off of that shifter handle.

Andy, it looks great. One question though, why is the roller cam bearings a bad idea? Not like you to take the time and trouble to do something you don't feel is worth it.

Good luck, Paul

Good deal, have some fun with that thing!
I'm about ready to get the old nasty GTX out again also.

I modified my core support so it can be removed. Sure makes pulling the engine a lot faster. With the overhead crane and the carb plate tilter it is literally a 5 minute job. I can remember years ago wrestling an engine hoist around in the driveway for several hours trying to install the engine the first time!

Interesting stands the car is on. I might just make a set of those.

Very handy stands, I use them all the time. Quite safe also when bolted in place as they are basically impossible to tip over.

Well making down the quarter mile has never been a big priority with me. This car has big brakes, big anti-sway bar up front, big torsion bars, etc. It isn't designed for drag racing but it does have enough power to do okay.

It would be nice to see how the dragstrip dyno matches up with the engine dyno you use. Being only about 15 minutes from Woodburn Dragstrip... Bring it to the Mopar Nats at WB and while you stand around your tables I'LL make some runs in it.

That sounds funny when there's shoe polish on the window.......

What were the issues wth the roller bearing cam?

Hello Andy,

Did you have it on the pump with the exhaust manifolds in place.

Re: 512 on the hook - 04/20/10 07:42 PM

I ran it on the dyno three times. It spun a main bearing the first time we ran it so the engine had to be pulled apart and redone. The second time it filled the Oberg up with trash so we pulled it apart again. Couldn't find a problem the second time so it went back together and back on the dyno the third time. Last time the Oberg stayed clean so now it is heading into the car. This engine has been cursed since the beginning!

I ran headers for the dyno session just because it was easier than rigging up the manifolds. With the camshaft that is in this engine I doubt there is any power difference between headers and manifolds. The engine only makes about 575 hp. I thin the cam is about 240 at 050 so it isn't a hp monster. Just supposed to be a nice cruiser with a Viper like power curve.

The issue with the camshaft roller bearings is the same issue as the cross bolted main caps. Way too much work for too little gain. This was an R&D exercise that got a little carried away. I probably have $20K invested in this motor and it doesn't make anymore power than a good solid $10K motor. But that is the way it goes when you're trying new stuff.

I don't know the part number of the shifter handle. It is just the standard Hurst shifter for a Doug Nash five speed. I bought this shifter more than 20 years ago so I'm sure I've lost the box by now!

What are you using for a pan gasket?

Windage tray?

Older looking damper too - ever had any problems with older dampers? Fluidamper told me I should replace my 20yr old piece.
