Head id help please!

Hi could someone tell me what car models the following 2 heads came on?

1. Cast in head:

130 01620 01 and:
280 S/A

2. The other head has:

127 010 50 20

(This head came on the engine for a 230SL, which I think has the correct block, but not the correct block serial number.)

Any help would be greatly appreciated.

Thanks,

Ron

the no. 1 head is from 1968-1972 (108) 280S(twin carbed),1968-1974 W114(280). Fuel injected head marked 280SE/L.
no.2 head is from 1961-1965 220S,1965-67 230 SL, the 127 head can be installed on 129block(250 SL) to raise compression ratio. what is the block no.?

block number and one other head question

Thanks Takernz_30.

The block number is:

127 011 08 01

I'm hoping it is a 230SL block, because it has that 230SL head on it.

Also, do you know if the cams in a '69 230 and a '72 280 would interchange?
I'd put the 230 cam into the 280, switching the towers also. The 280 has a bad lobe, the 230 is stuck.

Thanks, Ron

the block no. is a match for the head that you're inquiring about, definitely a 230SL. Early M127s have 4 main bearings later ones have 7.
About the cams, the 230 cam has different cam profile from a 280, 280s have higher lift and longer duration than 230 cam, so, putting a 230 cam to a 280 engine, you'll lose some HPs, because it is designed for 2.3L engine not 2.8L.

I have read somewhere in this forum that someone installed a 230(carbed) head, 280 (carbed) cams into the 280(carbed) block, the swap gained him about 10-15 hp, due to longer duration and hi-lift cams from a 280 and smaller combustion chamber (thus raising comp. ratio) from a 230 head.

web source for cams?

Thanks again Takernz_30.

Would you know a source for cams for M-B? Otherwise, I'll have to swap the 230 cam into the 280.

On the 230, that cam is has small "freckles" of pits from condensation rust on 3 lobes. Maybe ok? Ron

I have no idea, I live in the philippines, if you go for a swap, check first your cam in the machine shop for cracks, bent, etc...
