Most likely the first to put a manual trans behind the 2020 GT500 engine. I need to do some research and get more details on the Leno Bronco engine swap.

That thing can Rev ! WOW ! 7600 RPM ! Impressive !
Funny thing is, he's running it up to 8500 RPM with the supercharger. They stopped at 7600 RPM because the stock injectors were maxed out.

Another video...


Says stock shortblock should be good for 800-900hp.
His current cam is running 0.900 inch lift on ported stock casting. :shock:

The 7.3 gasser is a boat anchor. Ford took a MONSTROUS 10 year step back in technology to appease a small crowd.
No, it's literally meant for towing. Consistent, heavy towing. In that regard it's more efficient than a diesel with less complexity. That's the entire point.

Palm Beach Dyno is putting one in their 2005 mustang.


Side notes, OBR already has and aftermarket ECU and harness for the Godzilla. Palm Beach Dyno will be offering a swap kit for S197 owners once they get their swap down.

Here is someone swapping a 7.3l into a s197 that currently has a coyote with a cracked block.

More interesting dyno results.

100HP gain with mild head work (stock valves and springs) and cam.

190HP gain with intake, mild head work (stock valves and springs) and upgraded CAM.

According to his post, these results should be able to be improved upon as well.
