Re: new 489 ZL-1
 
so, how it this running? Make any passes at the track yet? Mine is under way as another motor in the shop got in the way as it's going to LeMans to run in a vintage 'Vette. They used some of my "other" parts of another 427/433 I had. This one is a 4" stroke, .030 over pumpgas deal. Steel block that WAS mine. 074 heads and my 163 intake with a 680 cam and she made just over 740 Hp.

My 476 we hoping to get in the 800-850 range with 074 heads and 163 intake. A lot of R&D went into the "LaMans" motor that we are putting into my 476.

Albert, talking with the engine builder on Sunday, man he's PUMPED about this. Now this shop builds some pretty wild motors. and for them to get this worked up is pretty good for me. There's going to be a lot of time and effort put into this.

I really wanted to go with a stick, just don't think I can. so most likely a T400 and a gear vender. Goal is to be able to run in the 8's with it ON MOTOR. That will be a tall feat for sure i know, but I'm quite confident that 9.50 are the without much worrying. Trying to keep as OEM original as I can but for the headers. So when I open the hood, people think it's just a stock car. &quot;MIGHT&quot; run a FAST EFI set-up with a single thottle body for better road manners and we &quot;think&quot; we can pump gas the 13-1 comp.

But here in Ontario, it's a long winter, so will keep the updates going as they come. BTW here are some of the know specs.

- 052 block @ .100 over
- Eagle 4340 crank (lightened)
- Eagle H-beam rods 6.535 long
- SRP 13-1 piston (messaged)
- ARP bolt and headstuds everywhere
- 074 heads done by AFR and cleaned up some more [img]<<GRAEMLIN_URL>>/wink.gif[/img]
- 163 intake, cut, welded, complete redo on it
- Solid roller cam in the mid .700 range
- .904 Jesel lifters with priority oiling
- trends pushrods (trying to run 1/2&quot; double tapers)
- Titan sportsman pump.
- COMPLETE Calico coated bearings
- Cometic gaskets.

Going in my '69 Nova SS396 car.

So that's it. I have a few carbs I can run, but would like to try the FAST EFI and my buddy is the head tech guy for them and we've talked about what we can do.

Albert - what do you figure your weight savings is over a similar iron block/ iron headed engine?

Albert, just a little streetcar motor. Now for the serious build, that might be the 1200+hp 498 in the '67. That was a serious build

Albert, just got a bit of &quot;unsettling&quot; news from the machine shop. They say there must have been a bit of &quot;core shift&quot; in my block as there is not a lot of &quot;meat&quot; around the lifterbores on the drivers side of the block. So meeting with them next week to discuss and might have to drop the lifters back to an .842 from the .904's. Rest of the rotator looks good. Was warned about the amount of nitrous this motor &quot;can consume&quot; as they want to keep it under a 400 shot? Piston is out-of-the-bore buy about .015&quot; too.

I was glad to hear that the head stud's are a custom piece. Once removed, it was noticed that the threaded end into the block is about twice as long as normal and block holes are deeper then the OEM chevy? Must be why this motor made some jam and helped stay together. WE also have some trick's to help keep the 074 heads from coming apart too.
