Markus56 Posted December 22, 2011 Share Posted December 22, 2011 Hey guys whats up. What the heck happened to the Board? :-\ So what do you guys think about putting a holley 2 barrel (that i believe is 500 or 350 cfm, not sure yet) on a dual carb EA-81 block? Any ideas or experience with that sort of thing? I was going to port a single carb manifold and i already have an adapter plate to mount it with, and drop the whole shebang into my 85 wagon. ~yohn Link to comment Share on other sites More sharing options...

El Presidente Posted December 22, 2011 Share Posted December 22, 2011 I think the board is a little slow because of holiday crap.. What holley are you planning on using? What are you using it for? I'm running a modified Holley 5200 off a 74' ford pinto on my ea82. I'm still working out bugs, but I'm happy with it. Josh Link to comment Share on other sites More sharing options...

Has externally adjustable center pivot float, sight glass, 30 cc accelerator pump...but it's a square bore carb and wouldn't get the fuel mileage that a spread bore carb will. And, that's a huge carb for 109 ci, needs supporting mods. Exhaust work, free flow air cleaner and such. 5 speed, and a bigger cam to go with it.

Markus56 Posted December 23, 2011 Author Share Posted December 23, 2011 I went to my local junkyard and talked to them about the carb. Its a 500 cfm off of a ford. gonna clean it up today and start working on the block. also, doesnt the dual carb motor have a different cam than the regular one?

El Presidente Posted December 24, 2011 Share Posted December 24, 2011 A 500cfm 2 barrel is HUGE for a 1.8 and is going to be more trouble than its worth. Some of the motorcraft 2 barrel carbs ford used flowed almost that much, like the bigger 2100's. I know Ford used 4160 holleys on some of the early mustangs, but those were 4 barrels and those flowed at least 500cfm. A holley 5200 is a basicly a weber clone, moving around 370cfm @3"Hg and its almost too big for a 1.8l. Do you have any pictures of your carb?

spazomatic Posted December 28, 2011 Share Posted December 28, 2011 That carb would make for a miserable drive. the engine won't even come close to suckin that much air. Ironically, a 600cfm 4v would make for better driveability than the 500cfm 2v (the 4v primaries being smaller than they are on the 2v = better vacuum signal) get a weber. drives great and it's sized right....er. a stock 1.8 still doesn't use all of it's potential either Link to comment Share on other sites More sharing options...
