did gm make a 375 hp 327. a guy told me that he has one for sale. I looked at it today, took the #s off of the block. ( wrong ones) he also told me that it came out of a 73 vette. what info I can find doesnt show that gm made a 327 after 69. the #s I have are the ones stamped on the front of the block F0503WA. any body got any ideas. thanks
this one is not fuel injected. in fact it has a 2bbl holley on it. that was my first clue. it also had black valve covers on it. full of crap, yea, I think you might be on to something there.
a guy gave me the same lines not too long ago, 2 barrel ect. ran the numbers and came up a 73 307, not a 327
Isnt every SBC a corvette motor? Sure seems like it when you are engine shopping. Also see if he will pop a valve cover and let you get a head cast #.
Look at the rear of the block just below the head deck surface where the bellhousing bolts up and you will see some numbers similiar to these listed. 3794460....327 cu. in. year 62-64 3830944....327 cu. in. year 63 Once you get the casting number then go to MorTec.com and you can determine the original cubic inch of the block and the year/years that casting was used. These numbers will tell you the engine type, but not the H.P. Chevy did build a 375 HP 327, solid lift cam, and (Fuel Injection I think) 365 HP 327 solid lift cam, single four barrell carb. 350 HP 327 hydraulic cam, four barrell carb. They also built a 300 HP and a 250 HP 327 It seems to me they offered a 325 HP 327 a couple years but don't take that to the bank.
Price would also be a give away. A true 375/327 would be worth multiple thousands of dollars to a Vette restorer. Even in a used state.
I bought a 40 chevy a few years back that had a real deal vette 327 in it...sold it to a vette restorer for more than enough to pay for the car. If it is what he says you should be paying more than its worth for hot rod material as the restorers kill for these things
The 375 was also offered in the first part of 65 till the 396/425 came out. The front stamping should be RE for a 365 and RF for a 375 in 64. The 65's were HH for a 365 and HG for a 375. I think 65 375's were stamped HN if they came with transistorized ignition. The 325 hp engine that 408AA/D mentions was a chevelle small block engine option starting in 67 I think.
Sure as hell seems that way..and the're also ALL of the HIGH horse variety too.. For vette restorers, a real one can be the holy grail....for hot rodders, if it's a usable block with the right ci it makes no difference what it came from... I get the biggest kick out of it when guy's tell me they have a vette motor..... Unless it's a complete mechanical injected motor i could care less.. You are right, just as whats been stated already about 327's stopping in 69.. And, the 68 and 69 were actually large journal motors based on the 350 block. Same bore, different rotating assembly with shorter stroke.. The true 375 hp were small journal motors, and again, as was stated, are worth thier weight in gold to a restorer.. Sad part is, many guy's buy these thing's with the understanding that they are what was told to them and never check numbers to prove it..so, in some circumstances, they are only going on what they have been told, and in turn, tell the next buyer the same thing not having a clue they're wrong... Anyway, it's NOT what he's saying it is, period..whether he know's it or not.
The 327 was offered in HP ratings of 250, 275, 300, 325, 350, 365, and 375. Possibly at other horse power ratings as well. The 325 horse motor was introduced in 1967, same year that the 350 horse was discontinued. These were the same engines except the 325 used a cast iron intake and the 350 used an aluminum one. 1966 Chevy ll's with the 350 horse were competitive in A/S classes, 1967 models with the 325 horse motor and 24 extra pounds became the terror of B/S classes.
the earley vett was also 375HP 30x30 cam and 202 heads, as well as a problemed injected system, I always felt they were under rated. no SBC ever rated more then 230 HP without at least a 4 BBL.
Also, in 1968 the Camaro was available in 327 in 210 or 250 horsepower (2 bbl or 4 bbl.) It had 175/150 valves. Some of the blocks and heads in the 68's were cast in last 3 months of 1967. Remember, he who removes ID numbers has more than a little to hide.
