Hey every one. I just wanted to know if I build a 408w stroker....will I have to get my block clearenced or should it be fine. Right now it has the stock 2-bolt mains. Any advice would help?

Most stroker kits require clearancing of some kind.

[cindys_sn95]

it really depends on which rods you use, but as paul said it will most likely need some.

You will need to clearance a small amount off the bottom of all 8 cylinders. Easy enough with a carbide burr. There is a "stroker clearance tool" made for the Windsors. They sell them for the 351w to 408w and a 302 to 347. Its just a template you bolt to each main 1 at a time then draw the marks in the template with a sharpie, then grind all the sharpie marks off and viola a stroker clearanced block.
