The GM crate 427/480HP engine, is 10:1, uses the same 224/234 110 LSA the ZZ502 crate engine uses. The 427 makes 480hp around 5800rpm. The ZZ502, makes 508hp at 5200rpm. Same heads, same cam, 9.6:1.
Im almost positive that cam is a BILLET core, and availble for 200 bucks new
Camshaft Type (P/N 12366543)

I'm sure power was left on the table compared to a modern roller but I wasn't too concerned with that, besides have you ever heard one of these cams?

oh yeah the 427 cam, well the car was a 390 horse at birth, and when I got the car in 1973 I just had to stick a 425 horse flat tappet solid GM cam, last year I rebuilt the engine and actually installed the updated Crane version of that flat tappet cam. I want to run that car out route 66 soon so I went to a relatively calm driver cam. But I did put a nasty little Bullet flat tappet Cam in my 302 cougar with headers 2 years ago when I rebuilt that engine.
I think we all must have a sickness taking engines on a Saturday night!

GM 3959180 2nd design L-88, ZL-1 cam, also used in the LS-7. I'm just finishing up on my street car and found a NOS GM one that I used with Crower EDM lifters.

FYI:
Check those crower EDM lifters real closely!
I just bought a set last spring / late winter and one was absent the EDM hole.
I had to send it back and get a replacement.
Probably just a fluke, but just a heads up.

after doing some research i decided to go with a crane 168741 cam.in this small 462 cu in engine i think it will pull hard to 6400 or so and still have more low end grunt than the car can use.the heads came today and i gotta say they are a thing of beauty.the polished cnc chaimbers look awsome.
