Dart Pro1 227 Platinum vs older 227

Hello all,

I've searched here and elsewhere, and I can't find much on the older 227s. Only that the later were developed with wet flow work and are superior.

Anyone have flow data on the older versions? Or, direct comparisons?

Thanks.
Dave

There good , but the Platinum ones make more hp per cfm so if your reaching for every last scrap of power out of your build they will assist that goal!

Are we talking their Cnc ported in house heads?
These would be even better if they did the 60/40 valve shift on them..

The current 227 is sold CNC'd only. I just haven't found anything to show how much better they are than the old 227s.
Thanks

i know this is a little off topic, but a friend has a set of the AFR 227 cnc heads with the 60/40 and they may be to small for a fairly serious 423. I don't know how they compare to the Dart heads.

Anyone want to share how much power or how fast they
Have been with the Dart 227 heads?
Anyone compared them to the AFR227 not just on flow bench
But on track performance or dyno?
