That 454 must be a late 80's - early 90's TBI engine. All '76 were two bolt as far as I know.

Is the 427 a true 427 according to the casting #'s? Some people take a 454 block, put in a 396 crank and call it a 427 (because that's what it's now displacing). But the casting #'s will always show it as a 454, not a 427.

Go big or go home.
Cubic inches rule.

454 all the way.

427 rolls off the tongue better than 454.

 Unless you are talking about a 1970 LS6 454............... then that is a different story.

Yes, the casting number would be great. If it's a car 427 and a four bolt main, it would have been a 425 horse originally.

Depends on what you are looking for.

For nostalgia sake and a few bucks more per hp, a 427 is your choice.

For raw hp and tire shredding torque its a 454.

My 454 build is fresh off a dyno break-in. 557 ft.lb @ 3200 rpm, 449 hp @ 5000 rpm.

More or less a budget build with some thump to it for my 72 Nova. I had a 454 in the shed with most of the peripherals in hand so 454 was a no brainer for me, but to be honest I never considered going 427.

As others said, you have to check casting numbers to see what actual options you have.

 The fact that your friend wants the 454 and is offering a running 427 should tell you something right there. Nonetheless a 427 is more in keeping with your car and era.

Nope, big bore but the shorter stroke for the win every time!

Especially after that ride I had in this month's feature car a couple of weeks ago. He revved that 427 up real nice!!!

(This is one of those topics that will never have a winner...)
