I was looking on the internet concerning building an antique JD-A for pulling and came across your article dated 12-19-99. I have a 47 A-JD I pull with which has a power-block with Hinrich hi-compression pistons and stock head thats shortened. I was wondering if you picked up any tips or connections for making more HP out of an A-JD. Would appreciate any info you might have gained about your JD-A built up.

Hey Bub use the after market piston,like from Powr-Seal (Old M.W. piston maker)they are located in Desmoines Iowa. The stock John Deere LP Piston have a tendency to crack in the skirt and pin area,I just restored a 70 LP and they were cracked.I'm at work and don't have ph.#. Their is another piston supplier Henricks his piston look just like stock lp pistons but thicker,If you want to stroke use Funderburks short skirted pistons,he's located in Pageland,S.C. Email me sometime and I'll dig up some ph.# Gman
