EA-81 H.O. Build

Featured Replies

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.

Also i have all the parts to make this project happen. :headbang:

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.

Hey,

 

I think the 350 cfm adapted to a SPFI intake would be a great combo, I wouldn't use the smaller carb intakes though with that carb.

 

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.

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?

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?

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
