I have the original 350 in my 1969 SS Camaro. The sticker on the air cleaner says the engine is a turbo fire 350 ci/300 horsepower engine. Is the "300 hp" correct for my camaro (was the 300 hp a possible option for my car?). Remember it is a 1969 SS 350 Camaro. thanks guys!

If it an SS 350 the 300HP sticker is correct. The SS350 engine was rated at 295HP for 67 and 68 but for 69 the advertised HP was upped to 300HP. I don't know if there was any real difference in the motors, but I am sure some one here knows.

I wish I had the original engine in my 67!

The only two 350's that were available in '69 that I have ever heard or read about are as follows:
L-65 [email protected] [email protected] 9.0:1 CR 2 bbl.
L-48 [email protected] [email protected] 10.25:1 CR 4 bbl.

69 RS 355 Tremec 5-Speed 4.11's

12run,

You forgot the LM1 engine (4 barrel carb, rated at 255 HP). I dont know much about that engine, other than it was the replacement for the 1967-68 L30 engine (327 cu in., 275HP).

camp07,

To verify that it is the 69 L-48 (RPO Z27), check the engide code on the stamp pad on the block. It should be an HA or HP code if it is a manual, a HE code if it has a powerglide or and HB? if it had a TH350. There should also be an assembly date code on the pad and a partial VIN.

That info would be more reliable to determine if the engine is correct and original along with correct casting numbers, dates and the Fisher body tag. If you need help finding that stuff let me know. If you already knew that stuff, disregard this post .

Camp07,

If you have, one of the engine codes listed above it is an L48 which is the only small block motor SS's came with. The RPO Z27 is the SS package (L48 only I believe, not big blocks but I could be wrong on this.) The change from L48 to Z27 was a change in the way the option was listed by Chevy. I don't know if it was to make it similar to the RS (RPO Z22) and Z28, (RPO Z28). RPO L codes were engine codes and since the SS was more than just an engine package they may have wanted to change it to the Z codes which were special item codes. I do not know for sure that is why they changed it, that is just my best guess. Maybe someone with a little more knowledge about this than me will chime in.

The 300HP is an excellent stock motor for a street driven car but it's rated the old way and I really doubt it makes close to 300HP in stock form.
