Fuel system options---what do u think?

[Jake]

Ok guys,On my AMC 304 Im currently running a 4bbl holly with a edelbrock performer (non egr) it will not pass ca emissions, so every 2 years I swap back to the stock 2bbl and manifold(egr too) for 1 day. This last summer wile on rubicon, the engine cut out on the steep's both ways. So here are the options. Run the 2bbl year round;(. Elec fuel pump? TBI w/ 2bbl. TBI w/ new 4bbl preformer with egr. Not sure the best route. Is the TBI excessive? Can a elec fuel pump make up for the 1 issue I have?

I would appreciate any advice or ideas,

Thanks

Jake

I run a Howell TBI 670 cfm. They are 50 state legal and meet CARB. I'm very happy with this setup on the trail, no more stalls. I would make some calls before I purchase to verify that it will pass in your area.

A dual system with propane injection is also an option. you can run those upside down with out stalling.

I run a Howell also, I've been very happy with it both on and off-road.

Do you notice a huge gain in power while running the 4 barrel around town? (I assume so... ) and want that power for around town...

Personally, I would weigh running the 4 barrel around town, and when going to elevation, switching to 2 barrel (and during smog check years... )

Try out the 2 barrel with some climbing, see how it does... My 2 barrel gives me plenty of power for off road, as half the time i am not punching it... though when i do it gets her done...

Are you close to central Cal? I go up to Prairie City for my off road testing (unfortunately have not gotten past the "testing" lately, every time I go out there come back with something new to fix )

We'll have to meet up sometime up there on the con man!

Thanks guys,
yeah, JR i like the 4bbl for every day use and thought the 2bbl swap might be nice for the alt and steeps. Ive never been to prarie city, i will let you knoaw when we plan our trips for next summer. Gonna do a run to watch the hammers in feb .... no toys...I have heard a lot about the howell system, it seems to be the best way bust costly...like everything else... maybe it will be next winter's project. im not ready for propane just yet

Will an elec fuel pump make any difference?

thanks
