I have a 1995 S-10 4x4 w/ a V6 4.3 cmfi and was wondering what i could do to beef the engine up some? Everything in it is stock. And where to find it? I heard if I were to beef it up it could act as if it had the power of a v8 is that true, and if so how?
<font face="Comic Sans MS"> As far as I'm concerned that engine in that truck already acts like a V8 in a fullsize does. Raced one in a friend's 92 k1500 GMC with 350 tbi and the vortec S10 actually won. Just a thought</font>
As far as I'm conserned a 4.3 will never have the power or torque of a V8, but to help you could put on a
throttle body spacer ( I did, lot better response and top end on the hiway) Headers are good for hp and
fuel millage. Dual exhaust does alot as well

YES. Both Crane and Edelbrock make camshafts specifically designed for the computer controlled engines. Edelbrock also makes an aluminum Performer intake manifold for the TBI engines, Holley offers a high performance throttle body injection unit. JBA makes an excellent set of headers for numerous s-series applications. Then, there's always Nitrous Oxide, or a supercharger! GM Performance parts also offers such things as 4.3L Bowtie cylinder heads in many stages, but they're mostly for high-RPM power. Your only limited by your imagination or budget.
You can find them at any speed shop, like Jeg's or Summit Racing. There like $60-$70, or you can make your own cheaper. There more for top-end performance. The 4.3L TBIs intake has a spacer built into it. Just my $.02.
