just curious if you have run the numbers on the block. I know the valve covers of your new motor say 327, but 327's had a casted fin on the front of the block just above the water pump by the passenger side head. it's the only outside identifier of the 327. it's hard to really tell from the pic, but it doesn't look like it has it. just something to check out. but, either way a v-8 s10 can be a very fun ride
