i bought what should be a lt1 out of a 94 z28. The numbers on the side of the block say 327!!!! when i got it the heads were off and the intake. So i just need to know if i got the shaft and should go busting down doors. The numbers on the rear passenger side i can't really make out but i think they say "10125327" and the driver side has the gm 5.7LG SGI(or T) with F164 under that. Any help would be appreciated
If it says 5.7 then it's a 5.7 (350). 327 is just the last 3 digits of the casting number and it was a coincidence that it said 327, that doesn't mean it is a 327ci.
Everyone is correct. 327 was the casting number and has nothing to do with the engine size. The L99 (the 4.3 v8 many confuse with the LT1) has like 805 or 508 or something like that cast in the same spot.
Nothing to worry about. You got exactly what you paid for.
thank you all, i really didn't want to sound like a dumb @$$. I knew 5.7 is 350 it just kind of made me second guess myself. I always just seem to have that kind of luck, you know without bad luck i would have no luck at all....lol. thanks
