New set of Thornton W Z big block manifolds - bought these a few years back from Parts Place for use on a 455 build which hasn't moved forth thus never installed - so hopefully someone here can use them

from Thornton's site: Brand new castings of the original 1970, 1971, 1972 W30 exhaust manifolds W&Z. Our Thornton Reproduction custom brings you this this larger version. With a larger body overall, and larger ports, you can expect better flow and better performance. Larger exhausts can be used with these. These W&Z's were made for 2 1/2" exhaust pipes.

-These will fit Oldsmobile engines in A body, G body, and B&C body 1970 and newer. Made for big block Oldsmobile 400, 425, 455 with dual exhaust. For small block engines, consider our 350JR's or our shorty headers.

-They were also used on 1969 big blocks; the difference is that in 1969, the left manifold had a heat riser. Some cars up to 1969 have the steering box in the way, and the only option for dual exhaust is our set of GM S&W manifolds.

-If you are looking for performance gains for racing then stick with long tube headers. These are not made for racing; they are made for better flow and to offer another option that performs better than the stock manifold performance.
------------------------

Looking for $175 + shipping - noting these are heavy so possibly at least $50-60 ship costs within lower 48? These would be a great local Tampa area buy in that regard.

thanks

Good deal. If I needed them, they would be sold. Happy Thanksgiving sir.

 

I'll take them if these are the oversize outlet reproductions they don't make any longer

 

Thanks Android - there is a tentative sale for these but I will update status before day's end. These are 2.5" outlet manifolds per the Thornton site description I included in my ad, if that's what you're asking.

thanks

scott

 

Sale pending

 

If both tentative buyers fall through, I'll take them...

 

These are sold
