The V8 Owners Forum -

Thank you Dimitri. The D&D link is very good info and the budget stroker option very tempting. Are the Rover 5.66 rods standard "classic" items? Now I know what to look for.

Mark Lagrou at D&D is very helpful. If you dont get a reply to email just ring him. Its quicker that way

new stroke will be the (whole) difference in journal diameter, not half. You get half the difference in diameter in the throw of the crank, but by the time the crank does a lap that half distance is doubled for the stroke .
