Good morning, I need a pair of 1970 HP big block exhaust manifolds. Casting numbers will be : L = 2951865 R = 2899879. I would be willing to purchase for a fair market price or...

I have a pair of nice 68/69 HP exhaust manifolds that I would be willing to trade.

Thanks, Dave ............

Aren't those the same? Maybe a dumb question, but I'm not a numbers guy.

No, the angle/clocking of the bolts attaching the head pipe to the manifold changes and the design and the angle/clocking of the heat riser changed..

70-71 design

I have a set of NOS 70 hp exhaust manifolds. Got them in a trade deal. Perfect new no rust heat riser is perfect. $600 +shipping from Indiana if interested. Can send pictures if interested. Thanks
