    4.3 V6 question :)

    Okay so I have a 4.3 Xtreme and I was just wondering if it would be a good idea to get rid of the stock fan and go with an e-fan. Are they worth it? Im not looking for horsepower really. I just noticed when I was juicing the truck up with P143a (freeon) that my fan was throwing REALLY HOT air at me. If I do get one it will probably be one of those doubles or w/e. Do they help better when engine heat? As far as after i shut the truck off will they still keep going?

    What are the pros and cons?

    Thanks for any help!

    there arent any cons. electric fans are always better. they dont rob power off the engine, they can be wired into a switch so u can turn them on anytime u want or even kep it on, and their smaller (thinner rather).
    as for the hot air blowing at u thats what its supposed to do. the hot air is the heat being pulled off of the radiator.

    id suggest geting a pusher fan (mounts on front of radiator and pushes air past rather than pulls) it will reduce engine bay clutter, and 4.3 s-10s are cluttered, they need all the help they can get

    I was running a taurus Efan on my Xtreme and it worked great.Those engine bays are cluttered pretty bad..It was a pita putting headers on mine. They are fun trucks and you can make them run pretty good if you play your cards right.
    I lost mine in Katrina..got around 3' of salt water over the roof... ran a 13.22@102 1/4 before she went swimming tho,spraying the house down

    i have a 4.3 in my truck... their alright but they dont have any technology in them and they dont make a whole lot of parts for em.
    gm knew they were getting rid of those engines soon so they didnt bother putting any of the technology in em like they did the 3800s
    they are torqy sobs though

    I love my 4.3..its a tough little motor, bottlefed98 thats a beautiful truck..its rare to see the single cab bubble butt Xtremes nowadays.


    Was it hard to wire in the E-Fan and did it help it run cooler?
    Also, did it mount good or do you have to rig it?
    Heres mine

    nice truck,I miss mine.That pic was taken as soon as the water went down.Its nobodys fault but mine tho.It was left parked about 300 yards from mobile bay.
    I mounted mine with some universal mounting rods from the parts store.It didnt really help it run any cooler but it did free up a few extra ponys.If you really want to wake that truck up get a good tune.

    What all would they have to do as far as tuning?

    I feel like the truck has some "hidden power" in it..i just feel like it has so much more than it puts out.

    a cam, computer tune, and gears will take care of that

    the cam i got these specs from i dont think will fit the 4.3... but these specs would work well on a 4.3
    Basic Operating RPM Range: 2,500-6,000
    Intake Duration: 284
    Exhaust Duration: 292
    Intake Valve Lift: 0.509 in.
    Exhaust Valve Lift: 0.528 in.

    the problem with the 4.3s is the power ban is stuck so low in the rpms
    although u may not gain a whole lot of hp... getting the rpms in a more effective position will do it a lot of good

    its been a while since ive researched parts for these engines

    i think stock cam specs are

    intake duration: 185
    exhaust duration: 195
    lift: .420in

    depending on how serious u want to race a stall prob will be more trouble than its worth and it will definetly reduce ur gas mielage

    im prety sure stock stall is 1500 i wouldnt go any more than 3500 if u do put one in

    but gears by far will give you the most noticible gain id do either 3.73 or 4.10s
    and put a shift kit in the trans (a real trans pack not a computer one)

    i used to have big plans on fixing my truck up, but i decided to go with a car... im working on getting a camaro/ta to put a carbed 383 in

    stock converter is 1300-1400 I think,and you should have 3.42's out back.

    I havent had the truck in almost 2 years I not sure what the 1000ft was but it usually ran 8.50-8.60 in the 1/8th mile track here.
    Its a good ride to the closest 1/4 mile track so it only went down the whole 1320 a few times.
