Is it a 426 or a 392?
Thanks in advance.

If the Distributor is in the back, it's a 392.
The 426 has the distributor on the passenger side of the front of the engine.

If it's got the Chrysler Firepower logo on the valve covers, it could also be the earlier versions of the same engine.....331 (1951-'55) and 354 (1956). The 392 was built in 1957-'58.

Just FYI, the 426 engine of the '60s is an entirely different engine than the ones built in the '50s, and Michael is absolutely correct about the distributor location.

A lot of articles list the engine as being a 426, but this photo of a model clearly shows a REAR distributor, making it the earlier design, definitely (at least in this model)

The recent 5.7 family of 'hemi' engines is an entirely new design again.

That's why I was uncertain.My dad listed it as a 392 because of the Firepower heads,(the model it's going in is a replica of a 55 F-100 he used to own) but I saw multiple articles stating that it was a 426.

Does anybody also know what transmission it has? It looks to be an automatic(which is what I actually need).
Thanks in advance.

Yes, the photo of the model appears to have an auto box peeking out. Articles on the car say it's a Chrysler 727 Torqueflite, and that appears to be what's in the model pictured. To be sure, post a clear pic of tke kit gearbox and we'll be glad to identify it.

The BHE is probably not the best parts donor kit to be honest. Maybe the Moebius '55 Chrysler would be a better source, depending upon which specific trans you are looking for?

There doesn't seem to be a consensus regarding the engine's displacement, but it's definitely an early Hemi, with the "Chrysler Firepower" valve covers on it. Those (and the front wheels) were the best parts in the kit IMHO.

I am only using it because i have it on hand, my dad told me he didn't think his was a 727, as his had a stock trans from a 57 Chrysler.

I'll try and post a pic of the kit trans tomorrow if I get a chance.

Yes, and as I said above, many articles (including that one) site the engine as being a 426 hemi (from the '60s), when the photo of the model I posted above clearly shows an EARLY (ie '50s) hemi. Confusion abounds.

I found a few detail pictures of the actual car and it is NOT a 426 based engine.
The magneto is in the back which means it's an earlier 1st generation based engine- and my gutt says it's either a 354 or 392 ( both are very similar ) .
