Latest Chevy Hipo BBC head test
AFR kicked butt again. Fully CNC ported Dart 335cc didn't make as much power as the AFR 325 with optional CNC Chambers. Everybody else didn't even come close, but their price was also closer to 2000$. AFR heads are about 2500$ with the optional Chambers, Darts are 3600$. Makes me wonder if the additional 1100$ more for full CNC port makes it worth it with any manufacturer?
Also, how long are the chamber be as efficient if they get oil ja rich mixture in them?

Chevy High Performance June 2008.
502cid, 8,75:1 comp, 245/250 @ 0.050 solid roller, .650 lift, big single plane, 100cfm Holley HP series carb
AFR 325 with optional CNC Chambers, 2500$ = 660hp
Dart 335 Fully CNC ported, 3600$ = 650hp
My point was that Darts costs 1100$ more for 10hp less.

Paid advertising VERY TRUE!!, Only they know how pulls were done on both. Were both heads fully tuned and maxed out, timing,jetting spacers etc..., We don't know it most likly was a paid add by AFR. Thats how the mags work.
