ZL-1 City
This is something you won't see everyday. Two original ZL-1 engines sitting next to one another. We brought both back from the dead. Cylinder explosions, cracks, etc. One is out of ZL-1 #17 and the other is out of car #34. Both made stellar hp on the dyno in bone stock condition w/180 camshafts. Used some of my Stock Eliminator tricks and different ring combinations. 543hp on one and 558hp on the other. Made about 10 pulls on each one. Like to see what I could make with some mods?? The 302 in my new 67 Z28 race car makes 475hp. I'll have to post dyno sheets. Both 427s made just under 500lb ft of torque.
Enjoy, Jerry

Re: ZL-1 City
Chris,
You would have loved my ride back in the late 1970s and early '80s. All steel 1966 Chevelle original SS396 car with an old worked over Super Stock 427 that I built. Back then it dynoed over 660hp. This 3500lb tank went 9.70s and 9.80s at 132 mph in the heat! Note the 9.83 dial-in on the windshield. This photo was taken at Maple Grove over 25 years ago when they still had a walking bridge across the staging lanes. The NHRA NED Bracket Finals. Those were the days. When you stepped on the gas, it got your attention! I still miss that car! Jerry

Re: ZL-1 City
Jerry;
Very nice, and very "believable" numbers! If I may ask, what kind of dyno do you use, and do you run sweep or step tests? Eric

How much tq did you get out of it? Got a dyno sheet for it? A friend of mine is considering building a 302 for his 3rd Gen IROC Z and wanted to see the curves on a well built 302.
