Hi all just after opinions on these cams, as to wether they would be suitable for my turbo setup
383 strocker
ported heads
Single TC78 @ 16 psi boost
current cam is a mild comp turbo grind
220/208 .554 / .564. 115 lsa
Looking at a couple of Kelford cam grinds
230/238 .600/.600 116 lsa
or
236/248 .610/.610 115 lsa
I'm after something with a reasonably tough sounding idle and great drivability/ street manners and a bit more top end then my current cam.
Have heard the 230/238 it sounded great and drove well on a 5.7 but is sold as a blower cam, will it still work well on my turbo setup ?

Epp blower cam 232/240 .595 .608 115 lsa
Pretty close to the first kelford cam
yes would be keen, just would work out quite a bit dearer and probably take 3 weeks to get here going by past experience, New Zealand is a long way/echange rate/shipping/import duty, yada yada.

If i can't get a bigger AR housing,I will look at a bigger turbo at some point.
Looking back i think 383 was a bad move for this turbo, much better suited to std cubes.
Don't want to go to big, just my current cam is pretty small, idles like std
and would like a bit more mid range top end.
I have the engine open at the moment to replace an oil pump, so would be easy to do the cam while i'm in there.

Don't kick yourself too hard. My 388/T76 has gone 146 mph in the quarter at 3800 lb and only 17 psi. It will go over 22 psi if I want.

1 to 1 , 1 psi of backpressure to 1 psi of boost would be considered very very good, most setups would be more like 2:1 and 3:1 would be considered high
