New ZL-1 Block "Finally" Dynoed & Installed
There seams to be a lot of interest on this site and others in the new and the old ZL-1 blocks. For those that have an interest, "finally" my new 053 ZL-1 block is built, dynoed and installed. Built to factory specs with the exception of 10.5:1 comp ratio. Not bad for a factory rated 425HP plant.

Awesome!! Wish I could hear it run! What type of AC/heater block off plate is that? Just what I've been looking for.

Re: New ZL-1 Block "Finally" Dynoed & Installed
Thanks for the comments. This is my third ZL-1 engine with the previous two being 052 blocks. Both had there issues. neither looked that great and both had porosity problems that were easily solved but still a concern. The new blocks are vastly superior in every way less the nostalgia associated with the vintage blocks. I built the engine as well as the Camaro using all the necessary ZL-1 components that would have any noticeable effect on the way the car ran, drove or looked. The engine was built with correct 7115 crank, 403 bell housing and ZL-1 clutch configuration, 620 lift mach. cam, 074 heads, 198 intake, 4295 holly carb., ZL-1 Hurst shifter, 69 M22 4sp, Eagle rods, TRW forged pistons. For example, no BE rear end because that has no real effect on the way the ZL-1 ran or drove. They may have lasted longer but added no more to the way the car ran than the 4:10 12 bolt posi that I have in the car. When I drive the car I want to know that this is the way a real ZL-1 ran and drove when it was new. I hope to have the project completed by this Friday. I'll post more pics as soon as I can. I don't consider it a clone. It's simple a 1969 ZL-1 427 Powered Camaro.
Thanks again Rick
