Is the really a 71 LT1?

Re: Is the really a 71 LT1?

Terry, I was not sure if the EVAP sysyem was used on LT1 car's. That is why I stated I wasn't sure if the Yellow label was also used. I do know, if the car has it's ORIGINAL White Emission Label or part of it intact, with the 2 letter code (believe is AX) or the label part number #3994020, I think it would be very hard for someone to dispute that it wasn't an LT1 car originally. FWIW. Dave

I had a 1971 LT-1 where the air cleaner hit the BB hood. The definitely need the clearance.

Bunky------

I don't understand that, at all. If the LT-1 had a stock manifold, carburetor and air cleaner, it should not have contacted a big block hood. The big block hood is the same configuration as the 70-72 LT-1 hood.

I agree. Actually thinking about it, the hood was cracked at the peak of the air cleaner, but it did not hit the hood when I owned the car. Maybe a former owner made a mistake such as a longer air cleaner screw or something. But part of the air cleaner had definitely hit the hood at some point.

Another common mistake is to forget that the oil filler cap was placed on top of the air cleaner while adding oil, then attempt to close the hood - CRACK!

Re: Is the really a 71 LT1?

from all i hear about the car its probably not an lt1. several ways to tell.
1) high rpm tac, 6500 red line
2) single fuel line from tank. you can look at the frame on the inside passenger side and see the fuel line. only the lt1 had a single line. all others have 2 lines.
3)ti amp module. located under the hood in fromt of the wheel well on drivers side. if its been removed you will see the 3 holes where it was bolted on. you can look in the wheel well in front of the tire at the top and see the bolts and holes without opening the hood.
4)aluminum intake and holley carb.
5) this one gets the fakers every time, the ujoints on the half shafts are held on by cast iron rectangle caps/ bolts and nuts. not u-bolts. big blocks also have the caps.

these are a few easy ways to tell them apart.

...or somebody used a fatter aftermarket carb spacer/gasket. Even 1/4" thicker will cause interference.
