Would 915s have a J on them?
They did replace it in 74 but then left in 76 with the A body.
Assuming the same size valves, not a damn thing other then the different letters.
I tell you brother......had Chrysler EVER put 2.02 heads and 2 eyebrow flat tops in the 360, the 340 wouldda been done for.
Yeah but with wheezer compression.....that aint what I said in the quote. lol
A 10.2:1 360 (same as the early 340) with all the 340 trimmings including heads and cam wouldda blasted 350 plus HP through them HP manifolds. The 340 wouldda been a distant memory.
Yea it would have. Sorry I ment to quote Abodee
No problem....good discussion. Lets keep it goin. Maybe somebody that actually knows somethin will show up and tell us all how it really was. lol
Stroker would the 915s have the J on them?

That makes sense. Still though......the 360 never had the 2.02s. But plenty of 340s had to have 2.02 heads with "360" cast into them.
Ok I guess the only way to confirm is to pull the heads right?
Alright I will see if I can get the head off tomorrow and snap some pics for you guys to look at.I would assume so, yes.
So the reason they stopped producing the 340s is for a tax right off?
The "J" head is a 915 casting.
They may have a J, O, U, N or nothing at all on them. J is a generic term for the head.

The different letters were to keep track of the different molds in production. If they discover a problem/issue, they need to be able to trace it back to fix it.
