598 CI AFR 385CC CNC BBC Heads!!
AFR 385cc Fully CNC Ported Magnum BBC Cylinder Heads
Supercharge 598 Ci would like to know if this head would work good with my set-up.:lolhit: |
it will work great,,,,, you could also get the AFR 405
|
It should work great, if you are planning on spinning to 6500RPM+. Could be a little big but someone more knowledgeable than me can answer that better.
|
what size cam are you goig to use?
|
Unless you are going solid roller and high RPM, I would go a little smaller.
|
What boat, what supercharger, what HP are you looking for ?
|
Too big. Drag racers are spinning 8000 rpm with those heads on 598's. Also, there are guys here that have made 1200hp supercharged with AFR 315 cnc heads. Stick to the 357 cnc and maybe have a set of 2.35 intake valves installed.
|
you can use those heads,,,, there not to big you just have to put the right cam in....something around 254 264 650 655,,,you will make more HP with big heads and a small cam than if you had small heads and a big cam,,,,
|
345 is the optimum head for a 598 in a boat !
its about air speed , not volume !!!!! |
Thank you for youre advice but im going to contact RMbuilder for help I here hes the man!!
