Porsche 5.4l DOHC heads on BBC

[bretcopsey]

The recent issue of Hot Rod contained this interesting article:

And within it, this was written:

briefly describing how these DOHC heads were adopted to a 427 BBC. I cannot find any more info than from the photo caption. Does anyone know any more details?

Ardemas is local to socal I think I see his cars alot at local shows. He is also at the big 3 swap meet every year. This year its on RTTC weekend. He machines everything himself. Very inovative!

I read that article too, pretty cool stuff; Nissan Titan heads on a SBC IIRC. Neat stuff.

If you're looking for something out of the norm. Check out http://www.araoengineering.com/ too; 4-valve SBC/BBC/LSX heads (fords too).
