Yes 5 stage dry sump. Kay Sissle Has been gone a long time but was famous for his 6 cylinder race engines. He made a 12 port aluminum head for the 250's and 292's. Made other heads too but they don't matter. Mike Kirby had worked with Kay and took over the shop. I believe Mike was a fireman. He's still doing stuff but is getting up in the years. He's a great guy and has helped me with my build for a couple of years. Always ready to give advice. His crowd is 1000 HP 292's. I'm no life long friend or ever met Kay but that is the way I understand the story. The Chevy inline 6 racing crowd isn't that large so people tend to know each other.
While I did not know ' Kay Sissle ' --- I did see him Race , back around 1968 @ " Green Valley Drag strip" : he was racing his 6 - powered Batam.
I've been a 'SIX - Guy' pretty much since then . My 69 Chevy Nova still has the 'matching numbers 250ci - 155hp six. Just the last few years; I've installed the
Holley 390 - 4bbl on an OFFY intake -- just running the original 250. Then, too make it more fun - - I installed a Borg-Warner w/c T 5 .
That up-grade made my Nova - - - a FUN Car too Drive , again . Thanks for th' memories .
