Holley/Demon Carb stumble
so i still have the problem of the brass restrictor in the bottom on one and in the top on the other. how is this going to affect the install?
Is there a restrictor in the top of that one? I don't see it clearly in the photo. If you say its there, then I'm sure it is.
I might try running it as is. High IFR on the secondaries doesn't get my panties up in wad. If it has trouble getting on the secondaries, then take it out and put the IFR in lower position.
If there's nothing there, then squirt something in the hole and see how fast it comes out the bottom. Like I mentioned before, there's a chance the IFR is presed in under the cap.
Since there's no vacuum port on this block, it came was either a secondary or from some other carb (not the 3310).
Only thing I don't know is if the enlarged angle channel? could cause issues. Is it enlarged or just faced?
BLP and Braswell i'm swimming in part# just like i an on Ebay with ProForm Metering blocks. 3 emulsion or 5. standard cal or race. one says it for a 3310 and another says it for a 1850,3310, 6778,6779 and i didn't recognise the last part number.
another one says it for a 4150,4160 and 2300 series...........
If you're looking at used blocks, post up some links. Can tell a lot by looking oif the photos are good.
Yep.
IMO BLP is your best choice if your want billet. Have them set you up with a block tapped for both high and low IFR.
Then all you need is to drill set screws or can use what they offer. Won't need to tap blocks or press in bleeds.
BLP even has (or had) some press in bleeds if you ask.
Reminds me I need to order some...
