Offroad Carb for 350 Chev SB

johnboy007, Jan 23, 11:44pm
Currently running 4 barrel Holley carb and having issues with it flooding/starving on uneven terrain, need some suggestions for the following:

Alternative carb solution
Possible places who specialise in modification/tuning in Auckland
Other suggestions for resolution

In its current capcity it runs a little rich but runs well onroad, not sure if the offroad floats are a worthwhile purchase or if I should cut and run and move to an alternative.

Thanks in advance

Go to the holley/colt indutries web site. they used to or maybe still do make a special narrow float and chamber for hydroplanes, for the 4 barrel carbs, this minimses the '"bounce"' of the float that opens the needle and seat and stops it from flooding and stalling. they also offer a blanking plate with a hose fitting for the top vent for turbo applications. good luck

Google CSL Automotive, they do fantastic work. See what he recommends, I'm not a carb specialist.

Put in an electric fuel pump to feed the carb.

I used a 600 vac secondary on my 327 in a FJ40 for years and years
Every angle (except upside down ) it never missed a beat.THE SOLUTION
Is a "Float bowl breather whistle".It fits over the float breather tube extending it up towards the top of the bowl.Any good 4x4 out fit should sell them.i can get them through our Hotrod shop but cant promote it on here.If ya can get me your details some how i can help ya

Thanks everyone.

Wellabolla, email me at john-camps at hotmail dot com. Wouldn't mind getting hold of the parts and get some ideas around a suitable fitter.

Chuck it and put on a Carter AFB with the off-road spring-loaded needles kit. But make sure you put a 9600A adaptor between it and the manifold.
