This thread is a spin-off of the "Exotic "SOUNDING", high revving V8!" thread, emphasis of actually building and running a production road going V-8 Z car with a custom single plane crankshaft, whether that crank be scratch built in house or manufactured by one of the few custom crank shops around.
I’d like to keep all discussions pertaining to actually building this, not just a bunch of wining and crying about "why it shouldn’t be done", or pointing out obvious issues that have already been discussed and addressed etc. We already know a 6 and a 12 cylinder have an exotic note. Lets keep this on topic of 8 cylinders, in a V configuration.
1) To have an exhaust note that is similar/mimics the Ferrari V-8’s and/or inline 4 cylinder sport bikes in a road going street Z car that will see some autocross detail, back road corner carving, leisure jaunts across town, and to various local Z shows. Not a race car nor a daily driver.
2) Big power numbers is not the priority, exhaust note and drivability is!
3) Be the first to actually build and drive a one of kind V-8 project that is often talked about on many technical high-performance car forums, yet no one has done, (that we know of any how) and do so on a "Datsun" budget!
A question I’m sure many of you have; “Is this practical?” I’ll be the first to admit, NO, this is NOT practical! Generally we go to such fabrication extremes with our power plants for the sake of building more POWER! This project is for an exhaust note! I guess this project can be seen as an exercise in “aural bling”. So before anyone condemns this project as ridiculous, we already know it’s ridiculous, but we want to do it anyhow! Tony D. summed it up best;
Some people have a problem grasping a Machinist's Quandary.
Why does a machinist make a round ball captive within a cubic form?
Why does a machinist make a chain from a solid bar stock?
There are countless Machinists' Quandaries out there, and the reason to do them is always the same: To do them.
The thought and engineering that goes in to the front end of the Quandary is the reward. It makes the machinist think, actually think about what the project will need to be brought to fruition.
I said it elsewhere, this is not a narcissistic trumpeting of his accomplishments, but rather an informative blurb on what he is doing, and why.
1) Do so with a 8 cylinder piston engine, in a V configuration, (sorry, no rotaries, 2 strokes, turbines, 4, 6, 10, 12, 16 cylinders etc.)
2) Do so with as many off-the-shelf new/used/wrecking yard parts as possible, (keep cost down)
3) Small Block Ford or Small Block Chevy as the foundation, (leaning strongly towards the SBC).
4) Either scratch build the crank in house or order a custom manufactured crank from one of the various custom crank manufacturers. (Our lathe has enough clear swing over the bed to allow the manufacture of a 2" stroke crankshaft...)
