Holley makes throttle bodies that fit the standard square bore flanges.
http://store.summitracing.com/default.as...t=egnsearch.asp What kind of a distributor are you planning to use to get to sequential fuel injection? The siamesed intake ports would seem to be a problem for batch fire FI. Based on the firing order and the batch fire scheme (multiple injector pulses before the compression stroke), the cylinders will alternately run rich or lean. TBI or Sequential MPFI would solve this.
