Last October I found a 409 crank on Craigslist. I then searched this site to find out what a guy could do with a 409 crank and 348 block from 58. This site and the people on it are very helpful and filled with useful information!! So my original plan was to trim my 348 piston skirts, put them on 409 rods, wrap them around the 409 crank, bolt my 409 333 heads on the engine and I've got this cool combo!!!! Nope can't happen don't do it. Trimming 348 cast piston skirt enough will make them real weak. I was advised well by members on this site. So I came close to ending the plan and keeping my money. I started a conversation with Don Jacks!!! He had this cool idea. Take a KB-Icon forged piston for a 4" stroker bolt it to a BBC stroker 6.385 rod then wrap it around the 409 crank. The results are 380! Well i got my parts and finished fitting the assembly last night. It all fits! Its almost a zero deck height. Compression is around 9.5 with standard heads and gasket. Mine lower because I'm using 333 heads.
Hats off to Don. Heres some pics.
