what bore is it and has anyone built one?

 

4.250 bore 4.370 stroke. I don't know of anyone who has built one yet. I have seen a set of heads and they look awfully small to make serious power with that many cubes. They have cathedral ports like the LSX engines. The exhaust ports were extremely small. I'd like to see some flow #'s if someone has them.

 

I have, Using Raylar heads casted by Pro-Filer. Forged crank, Eagle H-beam rods and Mahle pistons. I seam to be the 8.1l guru for truck by default. If you have any questions just ask. Look in the multimedia forum I have a track vid up.
