Thread: Bought an old race car today.

Thanks Pat for that info. I'll stick a camera up in there tonight after I pull the back cover off and post them. Maybe you can see something in there that will help me make a decision.

I appreciate the input Pat.

Ok, I know a lot more about my new purchase than I did yesterday. I left work early today (was running into overtime) and tore down the engine and removed the transmission.

The transmission is a B&M. I found part of their decal on the top of the transmission case....the B and part of the M. The converter had a part number of 20413 on it and is also B&M. They call it a Holeshot 3000. It goes for about $ 475.00. The flexplate is a TCI with and SFI approved sticker on it.

Got the pan off. It IS a 4 bolt main block. (insert big smile here) The pistons and rods are all stamped with the number of the cylinder they go into and I can see where material was removed from the underside of the pistons on some and also on the connecting rods. So evidently it was balanced.

The pistons are forged but nothing special. The are Sealed Power 2244P .020 over. I researched that number (it is an old number) and it works out to be just about 9:78 to 1 with my 62 cc heads. The connecting rods have no real number on them except for GMA and 687. I couldn't find that number on the internet.

The cam has a number stamped on the back but I couldn't find it anywhere either. It is SE1090P. But it is going into the trash as are the lifters because I found the 3rd lobe from the back is wiped. Every other one is perfect except for that one. Maybe a bad break in proceedure or they set that one too tight? Any thoughts?

The engine also has screw in plugs instead of tap in ones, and the inside is really clean. However, it will go to my machinist for a hot tank and complete check over. The crank spins very freely in the bearings, and the bearings all showed some minor scoring, probably from the cam shavings getting circulated. The journals are all nice on the crank and it is marked 010 and 010, so the rods and mains are 10 under.

The crank is not remarkable either, the part number is 3932442 which comes up as a cast crank, medium journal with a 3.48 stroke. Being that this will become a street motor it will be more than I need.

Finally, the oil pan has no markings but is a deep flat sump model and the oil pump sits way down in it with a square pickup........some brand of racing setup obviously. It also has a heavy duty oil pump driveshaft.

So, that is what I have and overall I am really happy with my purchase. I got a lot of nice, expensive parts and a good basis to get my 46 running. Thanks for looking and for all the advice and tips.

Oh, tomorrow in the daylight I plan on looking inside the rear end. I have the junk man lined up for Monday to come and take it away so I have to get moving.

Way to go Don! Must feel good to see quality stuff inside.

Yeah Steve, I got to sit in the shop today and fondle all of it. I also found out the carb isn't a 650 double pumper, it is a 750 double pumper. I read the part number wrong. Too much for the street but probably ok on the track. I also don't think the guys who built the engine were the same guys who built the car. The engine is done so well and the car is really thrown together. I would guess they bought a built engine and did the rest. Probably why they toasted the cam on break in too.

I feel like a kid at Xmas time.

I have been following this, what a score!! I was waiting to hear what was in the rear end before I posted but we haven't heard anything yet

Rust was in there. I pulled the back cover off today Ken and there wasn't a drop of gear lube in there, bone dry. So rust had ruined the gears and also the mini spool. Nothing worth anything so I kept the Mr Gasket rear cover and the rest goes with the car when the junk guy comes Monday.

I did find out what the clunking was when you turn the yoke. Not the gear lash but the axles being sloppy inside the spool. Not sure what was up with that, but since I didn't want it anyway it didn't matter. Oh, the gear ratio was only a 3:42 also.

Thanks for asking though, I forgot to post about that.

Don

Great fine. It's all about the hunt.
