Don't have the flow figures handy but can dig them up next week. Ideally 2 x 45 dcoe's and am chasing manifold and linkages if anyone has them. It will start life with the su's just to get it mobile again but am well aware what a pig it will be until I get appropriate carbs. Kinda figured duals are the way to go, are the beehives a big step up? Who in Aus. supplies springs? Also another chap just mentioned they are GM lifters and pushrods so presumably they can be had here too? Next does anyone in Aus have or produce extractors for them?
The 142 is going to be a bit of a toy and I am not really concerned about low speed drivability (within reason) or fuel efficiency, am chasing as much power as can be reasonably had. Don't want a full on race motor but as close as is reasonable without mass mods and such.

Cheers.
