Indy LA-X vs. Eddy heads

and do you gain more than if you were to just bore out a 360 a bit?

Were getting off the OP question, but a better detour then the bickering(If we ignore it, it goes away by it's self!:clock:

any Hoow, you couldn't bore the block to equal the CI of a 4" stroke.

the 340 was marketed as the BIG BORE Hunter because of it short stroke and big bore. The bigger the bore......the bigger the valves the more power you make(at a high rpm)

The 340/360 with a 4" stroke can have larger valves(with in reason) and more CI ......could make the same power at much less rpm.........longer life of valve train.....and cheaper valve train.

Also for the same power level, the stroker is much better street manners.
