I thought the 44IDF would be too much, but might work with the smallest venturii. Seems you figured all that out and even that the smallest venturii wouldn't work well. I'm glad you do so much documenting -- I point people to your well documented Rambler pages all the time. You might want to stress a bit more that your engine is HIGHLY modified needs the 38/38 over the 32/36. You do point that out, but someone quickly reading over the carb page might miss it... I've been known to quickly scan a page while looking for info. I didn't have as much trouble as you with a WCD in turns and drove my car more aggressively than most would... or maybe I just didn't pay enough attention? I do recall a couple instances where it "stumbled" a bit coming out of a turn, but only when pushed real hard... as you do a lot in your rally driving. Most of the issues people have with the WCD is just worn out cores... especially around the throttle shaft. That 44IDF info might come in handy for someone with a larger engine. It might work well on a 232, if not that certainly a 258. The higher rpm capability as well as 36 more cubes of a 232 might just be enough though... but I'd try the smaller 32mm venturii ("chokes"). The 62 more cubes of a 258 should be enough for the larger 36mm for sure, especially in a built-up engine with better cam. I'd think a Clifford or Offy open plenum intake with an adapter plate would be wonderful with a 44IDF, but could mod a factory 2V intake or even a 4.0L EFI intake for a cheaper way to go.

(of course there is a middle [high performance] path -- that's what engine builders do! existing metal re-engineered. and of course that can be fantastically subtle. i was speaking off the cuff for the point... not stating clear fact.) yeah, chopping this carb up not worth the substantial effort. i had the 38/38 DGV right there on the shelf... also each bore feeds it's side of the engine, so progressive wouldn't work there. yeah the 44 IDF would be great on a 258! (umm, i think? lol). i actually bought a pair of 32mm chokes (aka venturis) but while they were in transit i made the realization about driving in the switchover area so they sit in the box. but usage really matters -- drag racing is completely different from sports-car use, where the engine is most of the time somewhere in midrange. there, smaller is better. the smaller DGV tunes up fantastically easy. idle mix is dead-on 1 turn, an eighth turn either way is quite sharp. transition off-idle narrow and no flatspot. with the new plenum it needed a main jet; it was running 14.9 to 15.2 afr on 140 jets, with 145's 14.4 to 14.5 afr. |
