Re: Cloning/427 questions
Thanks, but if I'm taking out the 427/390 motor, it will only be for a ZL-1. I've purchased an old Tunnel Ram for looks as well, ya never know, and swapping intakes only take 30 mins. any ways.

Re: Cloning/427 questions
Don't waste your time on the old aluminum blocks, not at the HP you're looking for...unless you like welding/grinding/resleeving. We have a Yenko aluminum block sitting in our shop floor that was split umpteen times...go wtih the new GMPP aluminum block, or even better, a Dart/Merlin/whatever version...

Re: Cloning/427 questions
Rob, I'm really leaning towards using the Dart/Brodix/Donavan blocks as they'll handle the power with thinking twice. I would consider THAT YENKO block of yours though. It would be nice to open the hood, and see the "YENKO" on the block, snowflakes on the heads and intake, with a "fly-eye" and aluma-coated headers.

Re: Cloning/427 questions
I agree with Rob on this one. You need a aftermarket Hi-Perf block. You could always get an aftermarket block and have Yenko Machined into it, or if you know some one who is really good with aluminum welding, they could recreate that raised crest found on a vintage block. With a new block you won't be scared to take it to its limits, but with a rare block like an original ZL-1 or Yenko, I think you would find your self babying the car more than really hammering on it.
Rob, I see that your ET has dropped substantially. What did you do to get from 12.10s to 11.70s?
