Hi guys,
    Sorry for not having responded earlier, but there was a problem with [me] being unable to log in for the past two weeks.
James to the rescue! Thanks for your help James.

The block is a factory 2 bolt block.
Using ARP main studs, half fill of Hard Blok.
Bored and subsequently honed with deck plates.
Internally balanced (two slugs mallory metal) scat ultralight crank.
6" rods.
Fabbed oil pan with full kick out and directional screening for windage control.
The carb was the focus of a lot of detail stuff.
Perhaps all of it unnecessary, but heck I just plain love doing the work.
Quick rundown: choke eliminated, shaft holes plugged.
All sharp [leading] edges in airhorn radiused, irregularities smoothed and blended.
Thinned throttle shafts, button head screws, knife edged throttle butterflies, both vertical vanes and 'bumps' (800cfm carb) removed from primary venturis.
Cleaned up booster rings etc.
Thinned fuel transfer passage from main body to fuel discharge point in booster

A lot of painstaking die grinder, dremel, and hand work with fine enery strips (in boosters) etc.
Made screw in idle tubes (with 10-32 set screws)  for easier removal and replacement.
Standard stuff such as fuel well plugs replaced with screw in variety etc
Relocated POE to under air valve.

I'm missing a bunch of stuff, but kinda rushing as I just lost an entire (over an hours writing) answer I tried to post previous to this (I'm slow and went over the time limit?)

If you have any further questions, I'd be more than happy to help out.
I have a number of detailed pictures of the carb work, but I'm hopelessly incompetent with computers and how to post them etc.

Probably is a way to PM here? If so I'd be happy answer anyone who wishes to see some detailed
pictures.
Cheers
