Pretty sure the diameters are 50mm - I believe it's this kit?: http://www.efisupply.com/inglese_efi.htm
The engine builder is Barnett High Performance in MI. BR Cars in Colorado is doing the rest of the build.
I have been pretty much leaving it to the team - with my requirements defined obviously...I will have to ask about the oil pan. I still want a new/larger fuel tank on it too.
It is intended to be a cruiser that I can roll up and down the coast of CA, so I am not super concerned with every ounce of potential - I have access to faster cars to run fast track times with :-) I just want it to run strong, capable of highway cruising, and lay big burnouts :-)

For one who may be looking for the "9's", or just to utilize the greatest potential possible from the engine, if of an I.R. design, note that stack length will/is compromised from the potential "ideal" for appearance & packaging (hood clearance), and that the small individual air cleaners will interfere with top-end performance.
Also, at this level of build, did your engine builder discuss oil pan options/concerns? The unit as seen in the photos appears O.E.M. production, or at least of the same approximate holding capacity?
