looking into buying a spare 3.4 and building me a smog legal hot rod motor. im just curious has anyone ever built a naturally aspirated 3.4 that makes any kinda hp? its not for racing but i need reliability out of it as well.
i have found rotating assembly's that are .40 overbore with will give it a couple more c.i. thinking maybe with some decent head work and some intake help it should make some decent power gains.
has anyone ever built one thats still smog legal?
Bad idea, are you willing to throw thousands of dollars at it to get less than 50hp?
Stock compression, stock cams, custom intake headers and exhaust, + maybe bore it into a 3.5 or 3.6. not even close to worth the hassle.
The only way to make power from an NA motor is better flow + higher compression + race fuel = off road only
Supercharge it (with fuel mods) or leave it alone. Trust me on this one, i know a lot about these motors.
I can turbo a 2.4 2RZ motor and get more horsepower than that 3.4 is capable of on its best day even if has forced induction..
Send me the money you were going to throe at your truck and I will send you a Tornado intake thingy for more POWA!!
