Mudge Posted April 3, 2003 Share Posted April 3, 2003 http://www.camaros.org/copo.shtml Some ZL1 Camaro dyno configuration numbers are listed, it goes from 375HP to 523HP, both from parasitic drag and of course some "hop ups" like headers.

Mudge Posted April 3, 2003 Author Share Posted April 3, 2003 Umm, ok? First gen Camaros are one of my favorite all time cars, and the ZL-1 along with the Yenkos and Baldwins, were thee sheet of the day for GM. Quote Link to comment Share on other sites More sharing options...

DavyZ Posted April 4, 2003 Share Posted April 4, 2003 Another interesting "Mudge" article. rofl. Is it a Camaro thing? I'm missing something. Maybe it's like my dad used to say, "Son, if I have to explain it to you, it's no longer funny." Davy Quote Link to comment Share on other sites More sharing options...
Mudge Posted April 4, 2003 Author Share Posted April 4, 2003 I think I get it now, I think its because I posted a few 'articles' and things lately I wasn't getting it for awhile though... The ZL1 was a bad mother, although 375HP is sure not as astounding as 500+, considering the 396s also claimed 375HP configurations. Then again with 14x6" wheels on so many cars back then, and polyglass tires.... they weren't going anywhere very fast anyway LoL Quote Link to comment Share on other sites More sharing options...
David K Posted April 4, 2003 Share Posted April 4, 2003 How much real power?Although rated at 430 horsepower by the old method, Chevrolet never released actual power figures for the as-installed production ZL-1 engine. Numbers were tossed around for years until Bill Porterfield decided to find out. Bill had acquired an original block from one of the cars and enough NOS parts to complete another engine. The engine was subjected to 5 levels of test. RPM was limited to 6750. Engine Test Configuration Result ---------------------------- -------- All accessories, production 375.7 HP exhaust manifolds, Camaro chambered exhaust system, 36 degrees timing As above with 2-1/8" headers 418.9 HP replacing the manifolds Air cleaner, alternator, AIR 447.2 HP pump removed Carb re-jetted, timing set 444.2 HP to 39 degrees Chambered exhaust system 523.6 HP removed The ZL-1 was a legitimate 500+ horsepower engine. Almost 200 more HP just from removing the stock restrictions?!?!?! Holleeeeeeeeeee! Quote Link to comment Share on other sites More sharing options...
Mudge Posted April 4, 2003 Author Share Posted April 4, 2003 In all fairness removing the alternator doesn't say street car, some guys pull the wiring on them at the drags though. Quote Link to comment Share on other sites More sharing options...
