We havent purchased Jim Hand's book yet but is on our list. Maybe we should aim a little lower on the HP. Our convertible may not handle that much even with frame upgrades.
Great question Doug. Jim Hands book is a must. As fas as the engine. Do it once. Dont wish you had spent another 500 or grand more. But on the flip side . You have to be happy with what you have. There is someone always with more $$$$$$$$$$. Read the combo packages in the back pg 120 to 133. Awesome info.
