1970-71 LT-1 radiator shroud to hood seal

[Mike E.]

This is an early 71 car, and TIMJG says "those with the power bulge hood used a three-piece seal in 1970 and 1971 up to about s/n 8000......"
There are adhesive remnants on the radiator support that would indicate that is true. However, those remnants give me the impression that the center piece may have been narrower (front to back) than the two side pieces. The reproduction houses are no help--they all have their kits, and all their kits disagree with each other.
What has been found on 70 and early 71 original cars?
thanks

Going from memory my old 71 LT-1 S/N 1914 the center seal was slightly wider and taller then the 2 outboard seals.

MY early 1970 has a long strip on the radiator. A 8" strap on top of the core support by the fill cap & about a 12" piece on the drivers side nothing in the middle. a long piece goes all the way across in front of the core support.

My 70 LT1 #4441 has three seals on the top of the core support. The two end pieces are 3/4 inch wide and approximately 12 inches long. The center piece is almost all gone and measures 1 1/8 maybe 1 1/4 inches wide and approximately 12 inches long. It is a coupe . Hope this helps Curt

How thick is the center piece? Same as the other two, or thicker? (Top to bottom?)

Re: 1970-71 LT-1 radiator shroud to hood seal

Unfortunately, I could only guess because so much of it top to bottom is gone. My guess is that it may be slightly higher, but only a guess. Thanks Curt

Dave yours is the later single seal design not the early 3 piece design.

Paul,
Wanted to add a one piece to the thread. I was hoping I had a good photo from my 70 VIN 16803 (July build) but I don,t have any. Car is buried until April. That is a 3 piece for sure.

Here are several pics of the top of the shroud area. You can clearly see the adhesive remains for the two outer seals. The middle one left very little to go on.PC192548.jpgPC192552.jpg

Where you glue is where my seals are & the same length as your glue strips. I see No evidence of glue in the middle above the bracket. Feb LT-1 # 3893 it has 19000 mi.

Interesting question Mike. Here is just some of what I had to chose from today. 5 -1970-1972s here and two others stored elsewhere. All original. I think I got a little bit of heaven today.



To answer your question: center piece is 3/4-inch front to back, however the late 1970 LT1 shown has only one piece of foam (center), and so does a late 1970 LS5. FWIW: 1/2 to 5/8-inch high and 11 3/4 long. My best recellection of mine (which does have three paces) is that the center piece has different dimensions than that. My car is not reasily available at this time.
