i have a few 4.3 question

rev. chuck · 11-21-2008, 06:07 PM

anyone bought and used a carburetor setup on these yet?

is everyone rebuilding these motor's? 4.3's are notorious for going dead on #5 from improper piston sizing from the factory.

building your own mounts or buying them?

is there an adapter to fit the 4.3 to the toyota transmission?

i think thats all for now

Plenty of carb swaps out there as that is the easiest, Advanced Adapters makes all kinds of adapter kits you will need to look on thier site for the specific tranny you have but if you want to go auto trans- swap in a 700r4 then adapt to the toy t'case.
A good source for the adapters, headers and mounts is http://adventurous4x4.com//catalog/index.php
he sells the mounts for less than you could build them and has a very good discount on all the AA swap parts.
As for the 4.3 #5 cylinder problem, thats a new one on me. here in west texas we put alot of miles on our trucks and I know many people have put 200k to 400k on thier 4.3's with no problem. I put 270k on a '94 work truck before I overheated it from a heater core leak while trying to work it out of a mud hole.
We need more info on what you are trying to do. Year? model? tranny?

I run my 79 toy with a fuel injected 4.3 and a th350 adapted to a toy transfer case and i bog the crap out of that thing with no problems.
great little engine, and stick with the fuel injection, you'll like it alot better than a carb..
