I saw a 67 camaro with a 427 today. The engine was probably transplanted in so I was wondering if you could tell if the 427 was orginal by the vin# 124377N169499

 

Its not stock because that engine wasn't available in 67. I think the 427's didn't start going in Camaros until 68 with only a few being made, 69 was when most 427's went in, not exactly sure though.

427 came out in 65...

OBTW, AFAIK the 427 was the only big block that was ever offered with a 2-barrel carb (in '69 incidentally). Is that strange or what?

The first model year for the production 427 was 1966.

The only 2-barrel carb big-block was a model year 1969 396.

In Camaros I meant.

 

The first "official" 427 Camaro was in the 1969 model year.

1969 COPO Camaros with the all-aluminum 427 were known as the ZL-1. Very rare and very desirable. 50 or so were made. Very plain looking cars.

Other COPO 427 Camaros were also available but don't draw as much attention as the ZL-1s (Yenko and other 'tuners' come to mind).

The 'tuners' also offered 427s in 1968 in Camaros (as well as the Nova and Chevelle) but were/are not considered COPO cars by most people.

Since the 1968 cars, mentioned above, had as an option the 375-horse 396s, many of the 'tuners' kept the heads and intake/carb of the 375/396 (which are the same) and swapped in a 427 short-block.

With COPO cars available in 1969 with the 427, most 'tuners' just ordered them that way and made their own 'mods' to differentiate them from the 'factory' cars.

That would be COPO 9560 (aluminum 427s cranking out ~600hp), which there were only 69 made. The only other COPO was 9561, which was a iron 427, don't know total production or hp specs.

600HP?? I think it was 425HP for the aluminum 427 and like 420HP for the other.

 

I know the ZL-1 Corvette had 600hp, but I thought that the Camaro also had less than that.

I believe the factory rated the ZL-1s at 430 horsepower. Yeah. Sure. Whatever.

Sort of like when they rated the '67-'69 302 at 290 horsepower. Maybe at 1500 to 2000 rpm below their peaks.

Anyway, the 600 horsepower peak is different than what I've read.

My numbers say, on the dyno, 580+ horsepower! LOL.

The articles I've seen say there were two (2) ZL-1 Corvettes in 1969.

The ZL-1 with a cast-iron block was the L-88. Not a shabby engine either!
