I'll be really surprised if it gets close to 400 HP,I was cutting my teeth on hot cars and hot rodding in the early 1960s, lots of Ardun powered street rods got their clocks clean regularly by dual quad 1957 Chevy 283 motors that had been hop up a little in 1957 Chevy bodies Those little carbs don't help either. Do you know which block was used and how many C.I. it has now? Those blocks only had three mains caps, spin them up to far and the pin would fall out of the grenade and go BOOM Sorry to be a party pooper. I really hope they break or make over 350HP Please keep all of us in the loop

I don’t mean to take anything away from a very cool build, but I would think 400 is extremely optimistic. Ive never had a chance to look at those heads in person, but I agree with Cab. If the airflow is there, with the small bore/ displacement, you still need RPM to make HP. And as said, three main caps on these blocks. Thats a lot of unsupported crank span! Very neat engine. Hope his goals are achieved.

Not an Ardun (yet) but the 290 ci blown FH I built ok There's quite a few 325-250HP mild boost, blown FHs getting around that are not Ardun headed. I built mine with a 4 1/8" crank, H beams, Ross forged slugs and all three studded caps are billet steel. A short fill to the block, I ported it, added 1.6 in/ex valves, a custom blower cam and adjustables. Dual Stromberg WW 2 BBLs, it runs 8lbs of boost on pump 98 down here. Other than a popped head gasket, its been dead nuts reliable and after a recent teardown / inspection the bearings looked brand new

The ARDUN heads were originally designed for garbage trucks because the OE flatheads didn't have enough power.
I've never understood the infatuation with the pre-war relic platform. Seems like a lot of trouble for little horsepower.
Then again, people still race horses...

I can appreciate good work no matter what the platform. Just not for me. I guess it's what you grew up around.

My only experience with a flat head ford was with my neighbor. He’s building an “A” hotrod. Wanted me to relive the block. I had no idea what he was talking about, until he showed me😀. Turned out nice.

IDT 400 hp is going to happen. That exhaust tells me that the cam is mild.
