lookin for power gains... does that chip venom makes work

 

Actually, in most cases we can tune that "Big 6" for you - that is what we call those 300 cu in 4.9 liter straight-sixes that used to be very popular in these trucks - just give us a call at our number listed below if you'd like more info on this.

Glad to see another "Big 6" still out there running!
