Re: Which S10 style is lighter?
I had a 86 with a 4.3 that got 18mpg and removed it and put in a 5.7 tbi and got 19 MPG, had a chip burned and that changed from 19 to 25!. The main difference was the tune in the chip. Then after that I put in a alum headed 383 stroker with dual tbi's and it all started going backwards mainly because I stayed up on the revchip or close most of the time it was so fun!!Oh by the way it was a extra cab and weighed about 3400LBS with a tank of gas and had 3;42's.jim ps. yes I am aware that they did not put a 4.3 in a 86 truck so don't flame me for that. I built this one from frame up, building the truck I wanted at that time
