I have no stroker but a fresh 340 with 500 miles in the last month--wait--I rack the miles up quick, lol. I got 3.91 gears, 26 inch tires and a 3,000 stall tci streetfighter con. I been driving it hard and quick, just limiting my wot time to a few seconds till it gets its oil changed again, very soon I keep telling myself, lol
Its gets 8 mpg.
Good luck!
