small displacement turbo cam
this will be going with an iron 5.7L (5.3 block) and MP T-70 front mount turbo... probably only around 9psi boost...
the cam currently in is cut for n/a and some bottle.... I know the overlap is going to kill me with bleeding boost... I was looking at something smallish in the mid 220's duration and high 500's lift with a reverse split and wide LSA.... let me know what you guys think. Current cam is a 224/227 .576/.588 113+3
I've already been spec'd a 228/222 .581/.581 116 any other suggestions??? just trying to gather as many opinions as possible to research and look at.
Thanks in advance... this is my first stab at a custom grind f/i cam...

thats about what I figured, Thanks for the speedy reply! what about the reverse split vs. single pattern vs. traditional split pros/cons??? i know the cam choice isnt quite as critical in a motor with boost as a few lost hp can be made up with a psi or two... but I would like everything to run as efficiently as possible.

this probaly is to do with a different brand of engine.
we dynoed a tt sbc , std heads, std valve size , flat tappet cam
75 dyno pulls over 4-5 days
355 cubes
around .510 total lift
3 cams used
237 / 237 @ 114
256 / 245 @ 114
258 / 258 @ 114
ALL cams made the SAME power, give or take a bit due to different air temps etc , from time taken to change cams..
the cams did change the characteristics with the engine coming onto the converter....
don't get wound up in cams too much
for street stuff.... go with the general consensis
BUT if a race application, yes,,, lots in cam changes
eg 258 @ .050 dur to 276 @ .050 ( wooohoo)

Like I said... I know the current cam will "work" but I'm going to be replacing the pushrods and timing chain and a few other things while I'm doing the install of the kit. I might as well put a better cam in while I'm at it. The springs aren't very old (new 918s) plus I'm going to keep the lift fairly mild.
What I'm looking for is a cam that will serve my purpose better than my current one...

no others?? the cam will be stabbed in my 5.3 until it goes pop (125K mile motor) then when the motor is rebuilt, it will be reused. I dont think the few cubes will make any real difference since the motor will be boosted....
