[tirebird]

I was at a car show this weekend at saw a guy with a modified first generation Firebird. What really caught my eye were the 421 badges on the front fender and, of course, the tunnel ram intake with two big stacks.

So, after he parked, I asked him if that was an original 421 in his hoodless car. He said it was, except that he recently bored and stroked the original 421 and now it's a 460!! He changed the intake too.

I left scratching my head thinking how many of us would do that to a relatively rare muscle car engine?
