Anyone know of any performance upgrades out there for the 8.1 engines. And what is it capable of, hp and torque i mean. I am thinking about a swap into my 69 chevelle.
thanks
Josh

There's only one source I'm aware of.

Have fun. Very expensive. My 8.1 is still un-used because I can't find a computer, harness, and throttle body at a reasonable price.

I like the thought of the big block, but it is expensive. The big block looks good under the hood...I've found the conversions at a decent price, but 340 hp seems a little weak for me for so many ci.
But it's a TRUCK engine with gobs of low/mid range torque where a truck needs it!
