1969 Camaro ZL1 on Dyno
~~~Please Read Description~~~
I UPLOADED THIS FOR MY DAD, I KNOW NOTHING ABOUT THE CAR. SORRY.
Engine ZL1 427 all aluminum, pro top line head, comp cam, 1000 cfm holley,
5 speed tremec, 411 gear.
TWO PULLS: 1st pull inconclusive. Tires spun on rollers. 2nd pull,
tightened ties some more. Pull was better, but tires still spun (that's
the blue smoke)
I guess stock poly glass doesn't work with all this power. Will try again
with slicks on.

1969 Chevy 427 ZL1 Engine Dyno Test 534HP 501FT/LBS TQ
The 1969 Chevy 427 ZL1
It is an engine that is as synonymous with factory performance as is the
426 Chrysler Hemi. Few have ever worked on, owned, or even seen one in
person. In 1966-67 Chevrolet was getting there behinds kicked in Can-Am
racing. The 327 CI small blocks they were using were too small of a
displacement to get the job done on the Can-Am circuit. In 1968 the
development of the all aluminum racing 427 for the Can-Am racing series put
Chevy powered cars finally on top. Their success was so great that GM
decided to market the engine to the public for other racers to purchase and
would make a wet sump version to be offered, the ZL1. GM never intended to
offer the ZL1 in a production car, however, some Chevy dealers knew how to
get around GM hierarchy to get factory built race cars made using the COPO
(Central Office Production Order) backdoor ordering system. In total 69
1969 Camaro's and 2
1969 Corvette's were produced with the ZL1 engines from the factory,
complete with a factory warranty.
Promar Engines was chosen by Kevin MacKay of Corvette Repair in Valley
Stream NY to resurrect the original prototype engine used by GM for there
testing of the ZL1 engine in 1968. Promar had custom parts made for the
engine to recreate the engines internals. Upon completion the 1968 GM
Engineering Prototype ZL1 engine was Dyno tested and everyone can
finally know what the actual HP of a stock ZL1 is. The Dyno results are 534 HP at 6300
RPM and 501 Ft Lbs TQ at 4600 RPM. Promar Precision Engine is a
remanufacturer of all types of engines. High Performance, Marine,
Automotive, Diesel, Gas, Alternative Fuel, Restoration, and medium duty
truck engines are the main focus. Promar utilizes modern machines and
machining techniques to supply its superior quality products to the general
