Before you go too far down the rabbit hole with the 74HRT you should know that as of last October Whirlwind has quietly stopped supporting the 370/375 engines. Check their specifications tab on the all the RV props (i.e. 300 series, 74HRT, etc), it's in red letters.
I called them 3 times back in November to find out what is up. Unfortunately, despite several promises of a call back from the lady who answered the phone, they never returned my call or answered my question as to why the change of heart on the 370/375 engines.
Hmm...well, that's good to know. Really interesting to see the change of heart, just last August in an email they told me that the 74HRT would "certainly be a perfect match" for my IOX-370-equipped RV-8.
The lack of any information in that change is a bit disheartening.
