Sorry if double post...seems the other went into the wind? .
Anyway, the car sounds very cool Mark...lay some pics on us if you can! .
Nice user-name too although w/ a famous name like Hodges, well I'd expect a different brand?! .
(Astro-Jets were the Canadian-Pontiac Mk1V Turbo-Jets...air cleaner stickers and all!)
I think L36's were the highest HP 'advertised' 427's available in '66-'69 Canadian Ponchos but the L72's flew as an order (except in '67 of course) since they were really a Chevy chassis w/ Poncho clothes. .
