Not to mention that you will be without a truck for weeks while doing the swap

Doesn't sound very cost effective to me

yeah but with a 350 at least youll have some power.

this thread is not to argue the pros and cons against pulling the 4.3 for a larger V8. it's to give information to 4.3L owners that would like to modify thier current engine. if you'd like to start a debate of pulling a 4.3L for a 350, by all means, start a new thread. i'll be happy to post my opinions in it.

Im in on that one the number of posts for mods has reached to be lower than the number of regular questions and comments about ho wlittle power there is and mine is now one of them. any add ons to the 4.3 V6 greatly appreciated keep them coming. mine is in the works.

comp cams makes aluminum roller rockers for the 4.3, they are especially narrow for the center bolt styled head

i hope that you are planning on getting only about 8psi out of it if you are boosting at 15, turbo lag is a more than operative word, you should ask some shops if they could match or beat that price, and an intercooler would be a good thing to... engine longevity and more hp.

They make 'em for the 4.8 and 5.3. I called about the 4.3, but I have yet to hear back from them.

[JCFREAK]

The same kit for the 4.8 and 5.3 will work on the 4.3 with little modification.

the fact is...it's going to be difficult for anyone with a V6 to up and buy a kit like that without proof that it will install easily.

[JCFREAK]

The only change that will have to be made is where the intake hooks up to the throttle body. Nelson Performance carries the tune for the V6.

Not really a power mod, but it'll help your times if you have a manual:

Hurst Competion Short-Throw Shifter www.truckperformance.com $219.99

Nice thread..

Significant gains are to be had with stall converter (3,000rpm+), comp 266hr/270hr cam, head work, and some traction aids.

Or a blower of course. Combined with a comp cam and some stage II heads your looking at near 400rwhp.

I run another site based on the S10 truck and have been for awhile working with a few manufacturers on 4.3 ideas. One is complete, a Wynjammer S/C for the 4.3 truck that runs $2395 with programming, it nets 67 RWHP and is a simple addon that takes 4 hours. NO FMU or the likes!

Within the next month we should be getting the final word on a new intake from AFI. Predeterminded base ideals was it to make 10-15 h.p. on a stock platform truck and allow the changing of the injectors as need. $1500 was a target price number and looks to be doable. It'll have a seperate piggy back controller for running the injectors.

I'll keep you up to date and information becomes available but for those who want to follow it closer and talk to those who have used the Wynjammer and the AFI intake when it does become available, www.sicgmtrucks.com !!

will this "simple addon" also bolt up to the FSC 4.3?
