Nos 69 Chevrolet heatriser
 

Wanted a nos Chevrolet small block heatriser valve part number 3887023. Thanks call 9063371025 cell 9063373928 shop or email [email protected]

There is one on EBAY now John.

Ive got one slightly used not even rusty. I will have to check on the part number but Its off a 70 396 Nova.

Big block heat risers are larger than small blocks, unless the small block has the 2 1/2 inch manifolds that were used on Corvettes and 62, 63, 64 300 horse full size cars.

All I see on Ebay are repo ones.The one the Parts place has listed they list the GM part # but not saying NOS and not showing a box.

What is an NOS one worth?

Yep, going back to the ad I see were they said Part Brand as theirs.
GM part numbers re-poped by them I guess.

i believe u can get them from gardner exh as well

This guy had one on the Corvette forum last April, 2016 for $30. I am sure it is gone now.
Seems very cheap seeing it is NLA from GM.
