I thought the rangies had stromberg sidedraught carbs? Be good on angles but you'll have to make up a manifold for it or some type of adapter to go on top of your manifold.

X2 It might even work, as opposed to spending forever trying to tune something that wasn't designed for the car.

PS Forgive me if SU is another name for Solex or stromberg, but I thought old rangies ran SU carbs?

SU's have a dashpot mechanism that's basically a large piston for the vacuum to act on and thus control the metering needle. This makes them quite tall. The others use a diaphram in place of the piston and are more compact. They basically operate on the same constant depression ( CD ) principle

They can be made to work well, but like all carbs tuning requires expertiese and access to parts. Needles are more adaptable than jets, but if you have to modify them its a precision job.

Also many CD carbies don't have accelerator pumps - making their tuning all the more critical.

the motor came with the holley on it when i bought it and i thought a solex would be cheaper cause there a millions of dead rangies with 3.5's up here.. the side draft strombergs and the solex look very simular but the solex carby is a knock off of the original... they are practically the same but the dome bowl on top of the solex carbie is lower and wider than the stromberg.... if i could find a nice stromberg for a fair price id jump on it.. i was just lookin at my options... if i could find a set of SU's off of a old 1300 mini id go the custom manifold and be the king of carbie fed cool

I got twin su's off an old datsun thing for a very very reasonable price and i'm halfway through making the manifold for em. Dunno how they'd go as they are off a 1.6 i think. I should really pull my finger out and weld all the parts together and try em out.
Old jags and volvos (i think) had the strombergs too. I downloaded a manual from somewhere on how to tune strombergs too. Not much use to me now that I got su's tho.

yep, i had a SU here for a while, i never bothered to put it on but im pretty sure it was off of a merc. i think they run on all angles much the same as the moto carbies the yanks use....

subaru carbies are almost a bolt on swap and are awsome on side angles they use the ones of EA81 motors but they can be a hassle unless you know where all the vacume lines go.
