Math 101.060

[Reg Evans]

I am temporarily transplanting a D24 engine into my 1942 D22 coupe (J Lo)until I can have the D22 rebuilt.

The D24 engine runs well and has 110 lbs of compression in all cylinders.

I removed the head to inspect the cylinder walls and valves and it all looks good to the naked eye.

The pistons are marked .06.

My bonehead math question is.......if the stock cylinder on the 230 measures 3 1/4 x 4 5/8,How many cubes is the engine with a 60 thousanths overbore?

[Plymouthy Adams]

238.79

(stock engine is 230.21 for the record if you had to go .090 over to clean the bores..will be 243.13)

[Young Ed]

Tim what are my .030 over 218s?

[Reg Evans]

Hey Thanks Tim....I came up with 239 with my tape measure and my caveman math cause the bore looks like 3 5/16" with the overbore.

I'm gonna try this stuff out on the engine.

[Plymouthy Adams]

Ed..seeing as it is the same bore and .030 over..the answer is..221.80 (calculate stoke 4.375)

[Reg Evans]

The very tired D22 engine is out.

It'll be nice to drive this car without thinking a rod is gonna let loose any minute.

I notice you have a lift in your garage (which I truly covet)

How tall is it? What clearance does it require?

My wife noticed the color of the car and how tidy the shelves are. I guess it's all on your priorities.

I've been to Reg's shop. Very, very , tidy. I was more than impressed. Fun place to visit!

Don...when I purchased my lift few years back I built a 20 X 24 addition to my garage...this section has 13.1 inch ceiling unfinished and with the ceiling and trim installed it is 13 foot even. You could probably get by with 12 feet but I can send the mini van to the top and have plenty of room..my unit is rated at 7000 pounds and IF you do workon larger vehicles like trucks..the wider/longer 9000 series would probably suit you better.

As the cost of these unit is coming down due to competition in sales...I highly recommmend we older folks picking one up....my tired old knees are now my friends. There is very little work that can't be done on the lift...the bending over doing body work is elimated also...just be careful and be sure that you lock you vehcile at the preset heights and relieve the ram and line pressure when beneath the beast.

Tidy I'm not.

The lift is a recent and long awaited improvement. It was under $2K delivered to my house. No more dirt in the eyes and mouth,wrenches just out of reach and unnecessary sit-ups. AH !

My ceiling is 12' high and every vehicle I've had on it had plenty of clearance above.

Remind your wife that Christmas is right around the corner.

and how tidy the shelves are. .

I've been to Reg's shop. Very, very , tidy.

Tidy I'm not..

You be the judge:D Shot these pictures on my recent visit.

Reg, that's a pretty slick motor. Once you get it all dialed in, I'll bet you'll keep it in there. That's the late 50s Mopar 2 barrel intake, right?

It is Norm. It's going to be interesting to see how the engine performs with that 2 bbl carb. My plan is,or was,to only run this engine in the car for 6 mos or so until I have time to rebuild the original '42 engine. My friend who is helping me with the r and r seems to think the the engine that came out of the '42 might not really be a '42 even though the engine number says it is (might have been altered). If that's the case then you are right. The '48 Dodge engine will stay put.

Does anyone here have a book with casting numbers? The casting number on the '42 Block is pictured # 870229-3 and heads casting # is 870066-2

There is no date cast into the block under the distributer.

[Reg Evans]

OK...I'm going to install the engine in the Coupe today and will be reusing the throwout bearing. Should I lube the bearing and if so how?

[Don Coatney]

Reg;

Last time I had my transmission out I also re-used the throwout bearing. I added some grease to it using the pictured grease gun needle attachment.

Is the NOS throw out bearing you sent me not correct for your Dodge? Do you now have a need for it? I can send it back if you need it as I have not yet used it.

[Reg Evans]

I'll go to the parts store today and see if they have one of those needle nosed grease attachments.

Keep the TO bearing Don unless you can fax it to me right now:rolleyes: .
