To get to 3.7L - are you using a different crank? or will you really just bore it to hell and back and cross your finger?

Look at this thread. That's what I'm using now in the 3.4 250WHP Supernatural. SBC solid lifters.
The block is in machine shop getting the last bore correction to fit the pistons. The only difference between the 3.4 and 3.7 is the bore.
And of course, the entire rotating assembly is lighter. But to answer your question; yes, I'm working on it. I should have the the short block ready
in 2 weeks. I will not install it right away. I want to see how much more I can squeeze out of the 3.4 Supernatural and then the 3.7 will go in.



Glad to hear it! Sorry I thought I'd read that whole thread but I guess not. I really like what you're doing here.

LOL. Lou asked if you were using the 3500/3900 block. The LZ4/LZ9 block has a 99mm bore from the factory, but is incompatible with the iron heads. Try to keep up.

I believe they bolt up but since the bores are offset, things aren't lined up directly. I forget who posted a picture of one how it lines up... However it looks *possible* to use...
My engine builder was trying to sell me a 3500VVT block. It looked just like at 3400 block until I noticed the VVT menchanism and then I took note of the offset bores...

Lol!! I'm sorry Will! Louis made that question. I've been following your thread on your car and the lines look pretty good! When is it going to be ready?
