1969 L-88 Corvette engine questions
 
I have a original L-88 engine that is stamped TI0924IT. It is all original except for the head gasket as far
as I can tell. The camshaft is stamped 8911 and I believe that translates to part number 3928909. This is an aluminum 842 closed chamber head engine and I thought the cam should be the 3925535. Are these two part numbers both for the early 69-L88 engine, and
are the spec's the same for both part numbers?
Also the 842 cylinder heads dated 7 18 68 and 8 23-68, were painted orange matching the age of the cylinder block. My understand was only the 67 L-88 aluminum head was painted orange with the block etc. Can anyone explain this? Also is the correct head gasket GM 3887179 (reddish brown in color for this engine.?
Thank you

According to the Corvette Black Book, "T" prefix indicates engine assembled in the Tonawanda plant and suffix IT indicates 1968 "Heavy Duty-430HP" 427 of which there were 80 out the door. TAZ

And if the head gaskets were composite they are probably Victor ...

a couple of NCRS judges.

I was going to ask about a Vin stamping too also welcome aboard TS!
Besides deck pad, have you looked the complete block over closely for other stampings also is there an extra digit in the # you posted above...the I after the first T perhaps?
Great find either way but if Vinless and genuine, it's destiny must certainly be with one of the original cars?

Sorry the stamp is T0924IT, fat fingered error. The engine was used by Hilborn Injection as a test engine for there injection systems. It was purchased by a drag racer that knew Stuart Hilborn in 1969 and stored until I bought it earlier this year. I have restored Corvettes since 1977. The pad looks good to me and as I said I had it looked at by others perhaps more qualified and they said it was fine.
