I just became the happy owner of a genuine Nichels HEMI. It was raced in NASCAR and is all complete. It has 020 oversize NASCAR HEMI pistons. It will need a rebore to the next oversize, since two bores are scratched beyond what a hone job could fix. The pistons come with 1.09 pins, which was a unique size for the NASCAR 426 HEMIs back then. Rods are of 6.86" length and crankshaft stroke is 3.75".

The domes are huge. We calculated a compression ration of almost 14:1 !!

Do you know who could make me a set of custom HEMI pistons in 4.29" bore, 1.09" pins and less dome ?
