Blown Stroker BBC Head Test! @afr_heads 315 vs AFR 335. The 335s definitely flowed more, but more head flow doesn’t always make more power! Not even after you add an 8-71 @weiand_official supercharger and dual @holleyperformance 950s. The 8.5:1, 496 featured forged internals, a @compcamsofficial BR300-14 cam and Victor 454 R intake (NA). We compared the two AFR heads on the 650-hp NA combo then added the 8-71 blower running 1:1. Even with the boost, the blown big block had all the cylinder head flow it needed with the 315s. That’s why we test. Make sure to check out @richardholdenerperformance for all your cams, turbo and fuel system needs (DOD kits, waste gates, BOVs & tunes). Also check out our partners over at @briantooleyracing (BTR has cams and lots of other great products) @vortechsuperchargers (Vortech has blower kits) @scatcrankshafts (Scat has forged internals) @afr_heads (AFR has some serious heads!) #turbo #boost #junkyard #tune
