DHLA 40's are they big enough

I ran across a pair of DHLA 40s for $100 and I am wondering whether or not they are big enough to use on a 13b with a street port.

Too small, sorry
Maybe if You use both, but I've never seen a manifold for it.

Yeah, you'd have to make a custom manifold to use both. They might actually be too big, though.

I hear the 40's are equal to a weber 45, or maybe I am wrong... Let me check up on some things.

twm used to make a dual manifold, but not anymore.. if you ran dual 40mm carbs you would be fine.. a single 40 no way

man all this parroted knowledge ... one is too small, but two would kick ***. find an old TWM manifold as robert suggested. thay'd take some serious time to get tuned right but once you did they'd run like a bat out of hell. thruttle response and driveability with the 2 small carbs is better than 1 big one. all around great setup, but a bitch to tune.

p.s. I would buy them for 100 each and feel like I got an amazing deal. if you can't find a manifold the VW or old school Honda guys would buy them. I always wanted to put dual webers on a B18C5

I am backing myself up, looking in carb booklets because I believe what I typed is true, abet when I last had a 2 barrel was a little over a year ago.

And also, for someone talking about parroted knowledge, you seem to have just re-said what Robert just posted. Just a little fyi

LOL! Good response. It's been said that the Del 40's are equal to the 45DCO's but I don't believe it for a second. 40mm is a lot smaller than 45. It was a weber vs del thing in the 80's that spawned that. "A Del 40mm carb could be just as good as a weber 45, so if you buy a Del 45 imagine how much better it must be..." Just not true. The del is basically a reengineered weber with a smother and better transition circut which made them easier to tune, but they didn't stand the test of time like weber did. Weber managed to survive factory relocations from italy to spain and back 7 or 8 times and even survived a 5 year strike. As hard as weber stuff is to find these days dellorto stuff is even harder to find. They're still great carbs though. I'd like to play with them one of these days.

Not a lot of the manifolds still out there. they're really hard to come by. the last time I saw one sell it went for $450, but as Rob said I've seen them go for as low as $150. Check out Craigslist, eGay, and the for slae sections on all the rotary forums.

I have been in contact with TWM the past few days. Turns out they sold there tooling to pierce manifolds who I am now trying to convince to make another manifold for me.

This is a great setup, as said before tuning will take someeeeeeeeeeee... time

but the responsiveness is amazing much better then a webber 48IDA NO BOG

check out my vid I have a setup similar to that on my 4 Port 13b

Well I just got off the phone with the guys from Pierce (conference call FTW) and they said that no longer produce the twin mani for the 6 port so I will have to make the one for a 4 port to work.
