Can someone help me figure this out? i am needing to get some engine parts ordered to get it running.
I recently bought a car titled as a 1927, but some things are not making sense???
Engine has a two port exhaust head (28 and later), but has exposed push rods (27 and earlier)
Engine block casting number is 348532, serial number is 4556969. Casting has a bowtie with 17, below that is E298 (Made 5/29/2028)
Head has a casting number 348540, E288 (made 5/28/1928 I'm guessing) with a 7 below this.
Plate on the firewall shows job no 7220, Body no S15019.
Vin Plate on passenger floor shows Model Capitol, Car Number 3AA52992

Pistons are not cast iron or metal also.

Wheelbase is 104 on the driver side and 102 on the passenger, not put on the lift yet to look at that. Any direction to look at this would be helpful as well.

Nice car. My friend also has a 27 Capital with a 28 engine. His engine was cast August or September, and the car was low milage.

Your head and block casting numbers are 1928 . You say open push rods ? That is because you are missing the 2 side pans that cover them.

So, am I safe to assume this is not the original engine for this car?

Yes, you are safe to assume. What you have is a better engine.

Thanks coachman. Looks like the engine has sleeves. I have a couple pistons and sleeve walls pretty corroded and it will not turn over. Would I be best to put new sleeves, pistons and rings as needed, or bore out the existing and then oversized new pistons and rings?

I think that will be a question for the machine shop. It will depend on current bore size and condition. Standard bore is 3.6875". If you go too large, you will start getting thin between cylinders and experience head gasket sealing issues. Several of my motors are 0.060" over and that doesn't seem to be a problem. Sometimes motors are sleeved because the piston pin gets loose and gouges the cylinder wall.

If your head is original to your engine, I think you will find the block serial number stamped on the rear exhaust port gasket surface.

As accurate as I can get with my tools, I show the current bore is approximately 3.715 and the sleeve is .150 thick. Based on that, it would appear the current cylinder has been bored about 30 over.

Thanks Mike, I will check and see if it is there and if it matches the block.
