Re: Why no Ardun hemi head SBC conversion?

As a bit of trivia, In the 60's Ed iskenderian made several sets of single cam (per head) desmodromic heads for the SBC. They were very successful in tests. He advertised them in several magazines for a brief period but apparently the market was not ready for them so he didn't persue it. That would...

Re: My next debate: origins of the canted valve Ford cylinder head.

Big round ports were tried after "schooling" from Harry Weslake Ford small block heads. First used on the 427SOHC , the engineers took that path for "ultra performance" head designs. The 302TP had at least thirty port design changes during the time they struggled to make the head work. The canted va...

Re: SBF Dry Sump & ASK Numbers

As I told you I have many ASK parts myself . Blocks , heads , intakes. I have been trying to get in touch wi...
