MOPARMAGA said
Hey fabo friends,
I'm looking for help picking the right carb for street & strip, I have a guy from fabo that is a builder & going to have him help with the stuff I can't do.
Here's my build so far;
70 dart swinger, aiming for 2800 pounds
630 casting 73' 400 block
Molnar 3.915 crank
6.70 rods
1.320 SRP pistons.
Compression should be 11.3:1
I have trickflow 240s
I have a couple choices for intake, rpm & trickflow track heat.
Cam is a howards solid flat with 260@.050 intake & 264@.050. .616-.620 lift.
Automatic with 38-4200 stall,
I think thats all the info needed???
I have a #80509 830 classic hp holley now,
I don't have the budget as of now for a fi system so I'm not worrying about that.
What do you guys think?

If you had the cash for the carb Rusty posted I’d Beal, for that.

Aside from that, what you have is fine. I’d pin gauge every hole in that thing and write down every hole size.

I’d start with making sure you have only 2 emulsion holes ~.028-.029 and blank off everything else. Depending on what metering blocks that has, it may have 3 or 4 emulsion holes. If 3, block the middle off with a 6/32 brass set screw. You’ll probably need to to for that. If it has 4 you block 2 and 4 from the top.

Next up is to add transition slot restictors. I use a brass 8/32 set screw for that and start with about an .080 hole.

If you don’t have the tools to do it, you can buy them cheap or pay someone to do it.
