Should I keep these heads?
Not to add fuel to the fire, but the 340 installed in the '64 Valiant shown below is my car circa 1972. I dropped a complete '71 Demon 340/4-speed into a '64 V-100 2-door post.
I say "dropped in," because that's what I was trying to do.. to get by without having to buy headers,
Well, as you can see from the picture, it ended up with Hedman fenderwell headers on it.
When I lowered the engine into the car, once it was in place, the exhaust manifolds (1971 340's) hit the inner fender panels solidly on both sides.... no wiggle room at all.
Undaunted, and determined to use thee cast iron units, I drove the car to an exhaust shop that did custom fabrications to have them make me some head pipes to connect the manifolds to the mufflers.
After about half an hour of trying this and that, and measuring, to try to get around the clutch linkage, the guy gave up and said, "Go get a set of fenderwell headers for this S.O.B.!!!"
So, I did... as you can see in the picture. BTW, this was an original 273 car, although that makes no difference, probably (except maybe for the steering link oil pan depression.)
I guess production tolerances just result in some cars having slightly different parameters than others. I have a buddy who put a crate 360 Magnum into his '69 Dart GT and even with brand-new front engine mounts, he has to space the engine about an inch higher to keep the steering components away from his new TTI header$.....
Go figure.....
