I have bought a few engines from shafiroff through the years, including his 632's set up for pump gas single big dominator for my bigyellowcat. I don't think you will be over 800 hp but I could see low 700's hp and mid to high 700's ftlbs and be reliable.

did any of the engines you bought from them have the cnc ported heads? i just bought a 540 for my protouing 67 camaro from them, and it made 100hp over the base 540 they sell due to a full cnc port job...

i just want reliability and fuel mileage

the 632's had full cnc port job, they were supposed to make over 800 but in reality they made around 700

if you want fuel mileage I would use diesel. the diesel's will get more then double the fuel mileage.

Maybe you need some turbines.

Has two dominators, but at that point fuel would be the cheapest thing.

If you are looking for engines I have 2 new 622ci engines at Chief Performance in Ft. Lauderdale that are ready to go. These engines will make 725 to 750 hp and have a single carb, and all accessories. They are complete drop in ready for bravo application but can change bellhousing for transmission setup. Changing direction of project and motivated to sale. Can send pics and talk price if interested.

Fuel mileage in a 41 Apache with big power....hmmmm....something doesn't add up.
