528 hemi swap
without a doubt....yes
the heads have nothing to do with the bore / stroke cubic inch displacement.
The reason I asked is, I was wondering because of the block's size difference, if the heads were physically "bigger" in size, due to the bore...
As in some pictures I've seen (not been up close to both engine sizes as the same time, "side by side" to note that they are the same size, but in some cases, the valve covers on the 528 look a bit "bigger" then the 426....Now saying the bolt pattern is the same, but overall "fit" is pretty exact, see, Thats something I have yet to experience with Hemi's, side by side to see that the size externally, are the same.
I have seen other "Hemi's" side by side, the 331, 354, and 392, the old ones, first gen. are different! Unless what I seen was factory valve covers on one, and after market stuff on another.....Sadly, I didn't get to ask the questions then as I didn't really even think this deep into it as I am now!
I just thought that the different combustion chambers from the 426 to the 528 would have warranted the heads to bolt slightly differently from one engine head to the other....so they aren't Chamber specific heads!
Needless to say, interesting!
Which explains how someone can take a 528 or any of the "larger" Hemi engines and set up to look like a stock 426......They look the same on the outside!
