looking to find specs on 340-X heads.
To stir it back up.
For a fact.
I have a pretty original, but rusty 70 cuda, it has a 340 with X heads. Engine is still in the car.
And I pulled a set of J heads off a 1971 360 county police cruiser when I was a young, around 1982 that had 2.02 heads.
OK, I deserved that. I did mean stick out of the deck.But I thought only 68 and 69 . I have a 68 340 out of GTS I bought a set 20 over of KB 243KTM-020 Hyperkenetic Pistons and a set of Eddy 60179 heads stock deck height and .050 Eddy Gasket set . Would like Comp. ratio opinion . I was reading this post because I didn't know what X head CC volume was .
