Awhile back, about 3 years ago, my friend showed me a website of a custom engine builder that made DOHC conversion kits for the Gen. I SBC. My only problem is I completely forgot what the website and company name was!
I know this is a pretty vague question, but it's not everyday you see someone making DOHC for Gen I. Anyways, any help would be greatly appreciated. Thanks alot!
Here is one of them, but I would almost bet there are more. This IS America's greatest racing engine, you know. This is the conversion kit on a 302.
Are you thinking of the SOHC conversions from Pete Aardema?; http://www.aardemasohc.net/index_files/Page313.htm
If you go to his home page he's developing some Infiniti head conversions, but doesn't sound like they're ready yet.
The Moser DOHC setups that HRP put up are the only DOHC one's I remember, and they haven't been around for more than 30 years.
Hot Rod Magazine was always featuring this sort of thing. You might get on the net and try to find feature articles.
I did a quick search and found this. I still would not be surprised if someone else developed one. There was a lot of research for Indy engine conversions too.
