Stroke a nailhead?

[Mike T]

Back in the late 50's-early 60's Tommy Ivo and the other Buick racers used to stroke the nailhead to about 460+ c.i.d. Supposedly with stock rods and Jahn's pistons.

Anyone know how?

:beer I believe they used rods from a 364 engine with the smaller journal size in a 401/425 motor. Buford

I figured it was via offset grinding and custom pistons but didn't have any idea about the rods.

Dave Johnson from NW Buick Performance in WA was doing stroker kits for the nailheads before he went to work for TA Perf.

Mike would be familiar with it - give him a shout.
