Whats up guys, i'm about to build a 347 stroker next month with a CHP kit.
I've been looking for head and cam combos and i want to run AFR 185cc heads with the 72 combustion chamber.
as for cam i was looking into getting a XE274HR or a XE282HR.
which would be a better cam for those heads?

its a 5 speed. tremec tko
with the probe pistons i should be at around 9.5:1 compression.
i got an rpm2 intake

Why are you going with the 72cc chambers? I was just on the Probe website and with a flat top piston your compression would be 9:1 or less. The 58cc head would be about 10.8:1. I'd go with the 274 cam with the lower compression or the 282 with higher compresion.

My neighbor has the coast flat top 347 kit with TW 170's and the XE274HR cam, even with a crappy Typhoon intake and 1 5/8" headers it still runs good. Very torquey engine. Makes nice power.

I calculated with the Probe pistons flat -4 piston head volume id be over 10.5:1
with even the 60cc. i wanted compression at around 9:1 to 9.5:1 max. which with the 72cc it would be at around 9.48:1 pretty much perfect.
but which would be a better cam for the heads and compression?

Hey 89 this is not MATCH.COM haha :no

Like someone else mentioned go with the trickflows, the 185's and a custom cam and that thing will make WAAY more power than with those afr's and a over the counter cam.
