Guy thanks for your help. John Garutti at Cobra Automotive has got one for me. Apparently they have a standing order with Scat for 4340 forgies. Here in Australia if you want to race in pre '65 historic classes you can only use the stroke that was available in the day. The stock crank is a beauty but no matter what you do even cryo treatment they will eventually let go which is ok I guess but the damage to the block and rods is the problem. Happy Trails RV
1.149". There are Chevy pistons out there that are very close to this compression height. This plus a 5.7 Chevy rod makes for a nice combo for a high winding 289.where do they find a piston with a 1" compression height????
