Replaced the spark plugs and changed the oil using castrol 20w50 holds good oil pressure under just about any condition.
It has the "350" so when I mash it it goes. I can beat almost anything on wheels including all imports. The only thing that will outrun me is the 7.4 "454" V8's - the 400's can't compete. I am very pleased with this truck!!! I can run 10's on the quarter mile - hows that for performance?!
10's? Man, you must have built that silverado to the teeth, EVERYTHING would need work... My uncle has a 72 camaro with a 350 that put out 460 some odd horsepower at the wheels, and it runs 11's...What does your MPG look like? haha.
Probably pulls 1G on the skid pad too...
10 seconds in the quarter mile? Call Guinness!
Lucky if was 10's in 1/8 mile. What is that 350 really a blown and nitroused 383?
