95 ' F I Chevy 4.3 Ltr, How much power can you get from this engine Options

I have a 95' 4.3 Ltr FI engine that needs rebuilt,..what kind of power can U get from these engine's with factory ECU,..and spider FI system..?? Thanks

I think if your going to do a custom built V-8 in a 914, a 383 SBC stroker is the way to go. 400 crank in a 350, and you have an easy 6000 rpm redline. A great motor overall. Of course you can build more into it, but this is a very easy build, and the only build I would do on a small block.

this motor would be so outside the nature of what a 914 would need.

a 914 doesn't need stump pulling torque that a stoked out 350 would have.

better builds would be a 283, 327 sbc

or a 4.8 5.3 ls gm v8 and there are hybrid builds to do from these engines also
you could take the crank and rods out of a 4.8 and use the pistons nad block from a ls1 [5.7] or a 6.0L block and have the short stoke and large bore to allow better breathing heads.

the mid '90s lt1 v8's could build a hybrid from the "mini" lt1 that was a 4.3 v8 using the crank and rods and transferring them to 350 one piece main seal block and pistons for a 302.

Ah, to each his own. A 383 stroker loves to rev, makes power a bit higher in the rev range without sacrificing the benefits of low end torque. At least the ones I built. Is a much more tractable motor, with solid progressive power. That was my thinking.
