I have a custom cam motions hydraulic cam and brand new CamMotions springs/retainers/locks for this particular cam for sale. This cam was in my 355 LT1 for about a year. After I tore down the 355, I sent this cam to Cam Motions so they could inspect it and verify that it is in perfect shape. They did so and verified it's in perfect shape. If you need verification from Cam Motions themselves, I'll give you the invoice number and contact info at CamMotions.
The custom cam part number, verifiable again by CamMotions, is : X2291-2391-12, Core: 5310010

The Spring set is CamMotions part number 723030. To see the spec's, installed height, etc on these springs go to this PDF and use the PDF search for '723030'. http://www.flowbenchtech.com/porting...ion%20cams.pdf
The brand new 10 degree split locks are on that same .pdf. Look for part number 891000. The brand new retainers are steel and match up to the .pdf part number 894060. If you want pictures of the cam, springs, retainers and locks, let me know.
I paid $275 for the cam and $232 for the springs/retainers and locks. I'll sell them all together for $400 plus shipping. The idle was very aggressive and lopey.
Here's my CC 224/236 cam at idle.

This CamMotions idle was a bit more lumpy.

 

That cam would actually probably work pretty well with the turbo setup....

 

What? The cam motions cam? or the 224/236?
BTW-My Turbo shortblock is coming together nicely. I have;
4340 forged 3.48" crank (yes, I'm going back to a 355 from the 383)

4340 forged 5.7" H beam rods

Standard bore bare block bored to 4.030", splayed 4 bolt main caps w/ARP studs/bolts

-22 cc Diamond Turbo Pistons w/Total Seal AP series rings.

Just waiting for the rods (due here day after tomorrow) and the pistons/rings (due here next Tuesday). Erik at Victory Racing spec'd out my setup and the theoretical Static Compression ratio should be 8.8:1. Very boost friendly. I'm shooting for 14 to 17 psi at this time.

 

Both cams believe it or not. The more I read about setups the less I am convinced that the cam makes a big difference when you are under 240 degrees@0.050.

What cam are you going with now?

 

I requested a cam quote from Cam Motions on a custom turbo cam. This is what they sent back...

I know EngineerMike is using a 224/236 114LSA and is quite happy with it. He said he tried a turbo specific cam and was subsequently 'underwhelmed' by the performance so he reinstalled his prior cam.

 

I actually have a 224/224 .573/.565 114 + 0 that I will be running for my 383ci t88 setup, but I only wen that small because of the sniffer for MA inspection.

 

T88? ouch... What's the projected RWHP?

 

800rwhp @ 15psi pump gas.

 

Wow. That should be fun to pilot!
