i know if you bore it .40 over with a custom 3.75 crank would put you up around 280-300 Cui

but i found this out, interesting

Note : The Original design on the 4.3 Crankshaft's are to weak to stroke. The only option available is the Billet Steel Crank at this time . We are aware of companies that are stroking the stock 4.3 cranks , but with any serious power these cranks will break .

interesting

thanks guys, and to those "put a v8 in it" people... save it for the v-8 threads, If I wanted to motor swap thats where I would post, I want to stick with my mill, and make NA hp from a v6 because its different, and less expensive and hassle, plus I can keep the truck to daily driver standards with some more mild upgrades.
Thanks for the info on the crank however!

put a V8 in it.......:D







sorry if the truth hurts, but if you really want more displacement, a V8 gives you more for less..... plus it sounds better, and runs smoother.

If you think rebuilding and stroking a 4.3 is less expensive than doing say an Lt1 swap you have to lay off the crack because it will cost you twice as much for the 4.3. I am almost positive that when you stroke the 4.3 you will need that billet steel crank and just that is about $1000. That is almost the same amount you could buy a 350 for that is pushing 300+ hp.

MOST LT1 motors i looked at are 1000 on the cheap end and missing alot of stuff...then you need all the install parts and harnesses and to run the exhaust and if the motor is over a certain mileage like 90% of them are then youll wanna rebuild most of the motor anyways....and if you do find a 350 for $1000 its probably one of the piss poor 180hp gas crunch 350's or youve found an ungodly deal on an already built 300+hp 350ci V8
