hello I need help please!
Im having my Vette painted and I cant find any information about which engine is in it. Except that its numbers matching and according to the vin/engine stamp it says it has the base engine for my 75. In 75 there was an option to upgrade from a L48 to an L82 for a fee. The person I bought it from waas restoring it, and put the L82 emblems. so I dont know what emblems to put. I want to put the correct emblems on the hood, The last 8 on the engine is 5S410374. Any info helps, thanks in advance!
If it's numbers matching and the VIN code indicates base engine it can only be a L48. 5th position of VIN J=L48, T=L82. The end of the VIN is only the build sequence.
Sounds like you got it figured out. The L48 came with painted stamped steel valve covers. The L82 came with finned aluminium valve covers. The L48 has a harmonic balancer that is just under 7" in diameter. The L82 has a 8 inch balancer. There are of course many more differences. But these 2 are easy to spot.
Many owners of many cars put badges on that don't really belong. It's a pretty common thing. It's there car and they can.
As stated above, if a factory look is what your after, the L48 did not have badges. The aftermarket actually makes L48 badges, so you could put those on if your looking for a bit of bling.
2060 is the number of M21 transmissions which were only available in a L82. You could also get the M20 in a L82.
So the remaining 4000 L82s had either an automatic or M20.
