From experience I do believe in about 125hp per liter for really good 2 valve N/A competition engines (in general), which would be 300hp on a 2.4L being a target on its own. Apart from the combustion chamber and more efficient valve angles, the crossflow design dramatically changes heat management which is a considerable challenge in endurance racing. So yes I’m willing to give it a shot to develop it. I’m into cylinder head / valtrain development and manufacturing anyway, and consider this as a personal side project. thanks, Ken

I also have a professional shipping guy near Miami who can arrange pickup and forwarding 👍 thanks, Ken

Last year I had the 520 truck sent over from the US, so yes I’m fully aware of the extra efforts, sea freight, customs clearance etc. I’m fine with all shipping or pickup options 😊 thanks, Ken

Very much correct. In FIA historic racing, you need to stay with a SOHC and 2 valves per cylinder. The LY head was homologated for FIA group4 racing. I’m into custom valvetrain development and manufacturing, so once I’d have the head castings it’s an open road to completion... thanks, Ken

Hi, does anyone have a LY crossflow head available for reverse engineering? I’m considering to have a small series casted and machined. All options and conditions are welcome! Thanks, Ken

Hi, I'm looking for a spare J13 engine for my 520 pickup (1968). Anything available from a swap? The truck is still 100% original and prefer to keep so. Thanks in advance! Ken
