The HP in these engines is in the heads, intake and carburetor.
One shop may squeeze 15-20HP more out of an engine than another. shop. Another shop may use Oliver rods vs. Dyers or Carillo. Same with pistons... I THINK the RY45 engine use a Mahle slug... there are other companies willing to design or copy any part.
The secret is in the details... many different approaches to clearances, oiling mods, assembly techniques, tunes etc. No one guy does it the same as another.
Bloomer is smart enough to choose his engine supplier with great care. He's not the guy who simply buys what the engine shop is selling... his experience is valuble.
If he has confidence in Custom there's a reason.
