Flat 4 Vw Engine build 74mm stroker crank 90.5 piston 1904 performance engine

I have never built an 85.5 x 74 or an 88 x 74 because we have access to machine shops to open to 90.5 cyls. But from the research I did plus Chris has taken them apart. the pistons on the 85.5 and 88 will need to be clearanced. Most people do this DIY. but you need to have a gram scale, strip down the pistons weight them before and number them. put the weights on a piece of paper then make sure the weights are in spec after your done.
