    depends on which engine you have actually, 4.3L TBI is rated at 120 or 130 I believe, where as the "W" and "Z" vin 4.3l are rated at 190. CPI I believe is 180.

    As for 300hp..... only two ways to do that, nitrous or turbo from mach performance. 300 just isn't going to happen N/A and is pretty rare even for a supercharger. I think the ATI is rated for 270 at 9psi with an intercooler. hate to break it to you guys but it takes some serious work to wake these engines up.


    that's why I'm low and and slow :bigthumb:

    Just a quick question for you. Why ask a mod to delete it.... you can do it yourself. Go to the original post you made and click "edit". Then at the top click the box that says "delete" and then click "Delete" again.

    Anyway, I added 2 more cylinders, a set of GM Vortec heads, a cam, intake, carb, 10:1 pistons, and some other things and I have about 370hp or so. Oh wait... but I "just 350'd" it.

    Damn..u added 2 more cylinders? Props man...do they sell a kit for that?...and sorry for being stupid for asking but does a 4.3L v8 make much more power than a 4.3 v6? i dont see the point in adding 2 more cylinders...my v.6 has vortec heads...could i use those?....

    Well...the title of this topic is "4.3 numbers" and he replied to it saying "I added 2 cylinders" so the stock 4.3s are 6 cylinder 6+2=8 so he must have a 4.3L V8 or else he would not be posting on topic which surely he wouldnt do that...

    Note: Im not smartin off to chizwiz...do not take offense chizwiz
