Is my 1968 Camaro an L34 or L35 motor

[uscrichter]

I'm in the same boat with a July late July built '68 it has the 5500 tack with 4 speed and air that has a transplant motor and transmission, however it does have the original 3:55 rear end which according to the suggested power train groups should have been the  L-34, but it could have been ordered as an option for both L-35 and L-78, the last owner tore apart the head liner looking for a build sheet, never found one so unless I win the lottery when I get ready to restore and find one on the gas tank I may never know which engine it originally came with.

Higher chance it is NOT an L35. But you may never know. I assume you checked all of the other big block stuff?

[uscrichter]

Yes, heater core, proportion valve, master cylinder, power brake booster, exhaust system, fuel line, etc., addition to original paint on doors, blackout on rear deck and rocker panels(RS) car.

Crossmember, radiator?

Was the blackout on the rear panel original? Satin finish?

[uscrichter]

Yes, those all are big block items as well as the AC unit.
