4.3 v6 need help
 

i know that a v6 is not the best thing to have but i am still wanting to have some fun. i know that there is intake and exhaust but i am not sure of other things that would goood to do.

throw some ideas at me and if you know the names to any of your ideas let me know so that i can look them up.

nitrous the shit out of it!

I tried on my 2004 4.3L v6:

K&N intake
JBA headers
removed cats, single mandrel bent 3" exhaust
electric fans
march underdrive pulleys
CFM-Tech bored throttle body
75hp wet shot NOS
MSD 6a, accel coil, MSD wires
4:10 rear gears
HPTuners tuning software

..and with all of that. It was alot more fun to drive compared to stock, but no where near as fast as a V8 with the same parts.

So I swaped my 4.3L for a SBC and used alot of the 4.3L performance parts

a tune will help out to.ive read that nelson has done a few 4.3's

when you throw nitrous and sh*t on these 4.3 how well do those transmissions take it?

V8 swap :judge:

It's a pain in the ass, but worth it. Just going from a 4.3 to a 4.8 was a big difference. Now I've found myself wanting more and probably gonna go with a 5.3 now, but this time it'll be alot easier :D

Tune, CAI, exhaust, and take some weight off (lighter wheels, spare tire, fiberlass hood)




SilveradoMMk any noticable difference with the march pullies? How much you paid for them, and where can I find some?

Yes

the price keeps going up, I paid like $40.00 a few years ago.

What your truck ran man? Mine with the mods listed ran 15.8 on a GPS....from cabelas:devil:

I don't have track times... My Gtech claimed

0-60: 8.04sec
1/4: 16.01
HP: 237@5300rpm
TQ: 300@3200rpm

We'll see what the new V8 can net
