Anybody Using '68-'70 340 Hi-Performance Exhaust Manifolds?

[Dibbons]

Might use the 340 performance exhaust manifolds when I replace the factory 318 with the 340 I am building for our '72 Satellite Sebring Plus. Anyone with experience doing so before me that can give me a heads up on whether to use a 90 degree oil filter adaptor as well? Thank you.

My understanding is that HP 340 B body manifolds are extremely hard to find and expensive. The application should fit and work good.

I bought the repro 340 manifolds a few years ago and did use the right angle oil filter adapter. I have a 21/2" exhaust and use the smaller Wix filter. Although my car is a 74 Duster, so less room than a B body car.

I used HiPo 340 manifolds on my 72 with LA360 and right angle filter adapter. Was able to go with a standard size filter. I then swapped to headers without right angle and then 5.9 Magnum. No issues.
2 1/2 exhaust.

The manifolds were available in 2018, and I guess lucky I bought them at $600.

Sure they make copies
