@@aaronhollingsworth6808 those motors are rare as hens teeth. That’s like saying every Mopar guy wants the 413 max wedge versus the more available 440.
Some people may want the 428 for rarity. But the 455 is the motor to get, SD or HO, preferably SD. But for value I put the Ram Air IV at the top. For authenticity we all know 77 would be a 400. 455 is a good practical choice.
That year trans am did not come with a 455. My guess would be a low compression smog era 455 if it was swapped at some point. Most people who are building pontiac motors at this point are starting with a late 60's or early 70's 400 block. If they are serious they just get an aftermarket block which is an improvement over the stock castings.
@@DavidMorgan-gg7ic LOL You act like this is my first rodeo in the Pontiac game. Of course it’s been swapped, the last 455 you could get in a Trans Am was a 1976. And there’s a lot of high dollar aftermarket stuff around this engine, including nitrous so I doubt it’s anything stock!
@@Tailgatesntoolboxes I never said I was gonna restore it. I saved it from the junkyard. It will yield quite a few parts for someone restoring one in much better shape.
A TransAm! 455! Glenn
Hope you got a good deal on it.
@@RobertEast-i4y I certainly did bud, $600 :-)
@@SladeM.wow! Thats great! Good luck!
Actually the 428 HO 390hp is the engine pontiac people want, or the SD 421

You cant just say 455. Is it a HO or a SD. BIG difference.
@@Matt-gb3mz maybe so,but with the availability of aftermarket heads , etc today. any Pontiac with a 455 is a score nowadays !

@@SladeM.I’d restore it, it can only go up in value.
@@David12101 I have too many irons in the fire otherwise I would.
@@SladeM. same here, completely understand! She’s a beauty though. Someone will get a deal… or you’ll make a killing parting it out. 👍
