Outer Limits 4x4 Board

as the title says, thats what i have now and i need to buy a new carby and was wondering whether to buy another 600 or not...everyone keeps telling me to go a 350???

put the original back on it and you might be suprised. i had the orignal reco'd in my old panelvan and the difference it made was incredible and it used a hell of a lot less fuel, this was on a blue motor, wb van 2.78 diff in it

What mods to the motor ???
if its smoking hot 600
if std 350

I would put on a 465 or a quady. A modified quadrajet would be the best option.

yeah its standard and its in a hilux

600 were ideal for the 5.8's but an over kill on the 4.2.

Well & truly overkill, a 350 is more than enough, my 253 was worked & the 350 fed it nicely.

Make sure you buy & fit a Fuel Bowl Vent Baffle, it will save you a whole heap of grief on hills.

Agree on a 350.
Also to improve torque out of sight fit a set of venturi sleeves to the 350.
A stock 253 has less vacuum then a 202. The sleeves get the air speed up and helps torque and throttle responce no end.

I moved this to Gen tech & left the shadow in chit chat I will remove that later.

The 465 might be a goos fit, I agree, but then a 350 can be too big for a stock 5.0 if it's not set up right as well.

Check with Holley what dispacements the 465 is suited too, it would be my option over the 350 because it will give you better driveability and economy when you aren't using the secondaries. The 350 just pours petrol in all the time and only really suits a small cube motor when large throttle is used.

On the up side you can keep your existing manifold too

cheers for the advise
