Turbo cam recommendation needed
This is for a 383 LT4 with 9:1 cr. The car is a daily driver and will be putting the turbo on later. The Comp Cams guy recommended these specs.
0.555 lift I/E, 236 (050) degrees (advertised 281 duration) 114 centerline.

Here is my problem. My engine failed and have to go with a rebuild of course. It is my daily driver so I don't have the time I want to get educated on the turbo world which is very frustrating. I don't have the money right now to go with a turbo so I will be drving around for a while NA. I am looking for a cam that would work properly with a turbo.
Since I don't have a turbo in mind I suppose I can not expect an optimal cam setup right now. I would be happy with 600-700 rwhp. The stock ecm is good for 7200 rpm so maybe 3000-7200 for the power range.
I just want to get the engine built correctly so I don't have to go back inside it again when it is turbo time. Of course I am getting getting forged internals.

However I would definitely upgrade the heads with some additional CNC porting and upgrade the, rocker arms, valve springs and retainers to make it suitable for 7000 RPM.

Well I decided to build the motor NA because I do not have the time to do the research I feel is needed for me to be comfortable. Anyway, my mechanic has built 50+ 383 motors with 525+ fwhp with HR so I feel better going with something that is a proven winner. I just did not like all the unknowns hoping a turbo engine would run well NA.

Remember the KISS method? KEEP IT SIMPLE STUPID 
Sometimes like when I am having to replace my blower belt I wish I would have just built a killer 396. But when I stick my foot in it afterwards having a blower is pretty rewarding. I wish someday some one would come out with a new Dart M or similar casting for a LTx block. That way I could build a 454 LT4 engine, then I would get rid of the blower.......or how about a blown 454 LT4

I would kill for a block I knew I could 1)afford
2)put 30+psi on without worrying myself to sleep
