Hi Guys,
Has anyone mounted one of these on a Sonic Injection manifold that you can get for the greys?
and if so how did you go,any dramas i should be aware of?

Re: Carb and manifold combo
Edo,
That's the big 32/36, good for 270cfm@3"Hg (it's little brother has 23/27mm venturis and is good for 235cfm). Bear in mind your standard Strommie is 163cfm, the red motor BXV 210cfm and a WW 280cfm. You will want a pretty healthy grey to run the 32/36, but it is not out of the ballpark.
Cheers,
Harv

Cheers for the response Harv.
Is there a better option out there for single carb?
My 138 is pretty much stock.

Re: Carb and manifold combo
It depends a bit on why you want a new carb. If it's just for the cool factor, then any of the options below will do it. If you are after more grunt, then the carb alone will not be very noticeable - needs to have exhaust and headwork before you'll feel it.
For a simple single-carb swap, it is hard to go past a larger Strommie. The factory manifold can be used, though the bolt spacing needs to be changed for the carb-to-manifold joint. This can be done by adaptor plate, welding up the old holes and offset drilling new ones, or by using the old BXOV-1 throttle body (sacrificing a bit of flow). There are minimal changes to the linkages, vacuum, fuel or choke... essentially a bolt-up job. The original BXOV-1 Strommie with its 1 1/32" venturi (162cfm flow) can be upgraded to the BXUV-2 (1 3/32” and 201cfm) which is about right for a basically standard grey. You could go a little further with a BXV-2 (1 5/32”, and 210cfm), or go nuts with a Falcon BOV-2 (1 9/32” and 287cfm) though these later carbs are likely to give you pretty bad throttle lag in anything other than a roundy round or drag screamer.
The only drama with the above is it still gives you a fixed venturi. The variable venturi SU is a nicer carb. You can use the standard manifold with an adaptor (essentially a glorified 90º bend), which come up from time-to-time on eBay. Thre will be some work making the linkages, vacuum, fuel or choke line up. Going for a simple H4 will give you 188cfm, though the HS4 at 201cfm is probably the better choice. The HS6 will take you out to a whopping 297cfm, a little overgunned though compensated a bit by the variable venturi.
For a "cool" carb, there are manifolds available (second hand) to fit a Stromberg 48. This will give you a little more (175cfm) but is a fiddly swap for so little benefit.

Re: Carb and manifold combo
Cheerz Harv,
not really worried about cool factor,just after a bit more response, it has a larger exhaust and extractors.
Still trying to make up my mind about keeping the grey or getting hold of a HR disc front end and going red motor and trimatic.
Its running the hydra and i want something with more go so i can do highway ks and longer trips.Ive been told fitting a red six is as much work(engineering approval wise) as a V8 so not sure if i can get this grey running more efficiently or bite the bullet and go the red.Will a trimatic bolt to a grey with adaptor plate and if so can i still run my stock gear selector?,i want to keep it off the floor and avoid the T bar.
