383 Stroker need to chip?

I recently blew the motor in my 1991 chevy silverado, I brought it to a mech shop and I am having them through in a 383 stroker crank. I have talked to a few mechanics and I have gotten different answers. Some of them say that I will need a chip to get the full benefits from my stroker. Some say that I will be fine without.. what do you guys think on the subject? thanx a bunch

Just to make one thing clear, a stroker motor is not just a crank but a crank and connecting rods from a 400 block. Also be SURE to use a 400 flex plate that is or has been balanced for the crank you are using or you could run into big problems.

I know what is necessary to turn a 350 into a 383, just need to know if a chip will increase performance and or gas milage.

Most likely you will need a chip because it will need more fuel. Also do not expect to be getting any kind of great gas mileage out of a preformance engine like a 383. My brother had a 383 in a cutlass once and he was getting approx 450hp out of it and there was times depending on the way he drove it, he was refueling it every second day or so. It will depend on how heavy your right foot is. The way i see it , if you are having a performance engine built what does gas mileage really matter.

From what i have heard a GM Max Micro tuner from superchips is top of the line. However if you want the best performance and cost isnt that much a concern get a nelson tune for the best computer tuning available.
