I would like to wait till I get my FI plans sorted out, but I've haven't done a performance mod in almost a year, so it's time to try to maximize the full potential of this 6.0l N/A.

I currently have a tiny 208/216 .500/.500 113 LSA Crane camshaft and LS6 Springs. Reading up on the subject, I believe something more agressive and a bit more lift should give me noticable gains.

I'm thinking about the Vince "045" (216/224 .551/.551 115). It's advertised as "Powerful Choopy Idle and Dynamite with a Supercharger". Any idea how well this would translate over to a turbo?

I'll be upgrading springs, retainers, and seats also. Would the Vinci dual valve springs be too much? I already have hardened stock length pushrods installed that should get the job done.

Applicable mods are:
6.0l with ported/polished heads
Yank TT3000/Transgo
Intake/exhaust/ASM headers
Custom Tune

I know this topic is very subjective and has been discussed numerous times, but I would appreciate any comments.

 

I'm not too familiar with turbos, but I think that it would be good cam for you. Call Roger at Vinci and get his opinion, they're very helpful there. A lot of people think the Crane dual springs are not necessary, that 918s are fine which they are, but I think it is better not to mix and match different manufacturer's valvetrain parts.

 

Thanks. I'll try to give them a call this afternoon.

 

I'm interested in what Roger has to say about his grinds used in street driven, turbo motors.

Please report back.

 

I put a call in last week and they said they'll consult the engineer and get back to me. I"ll try to call again Monday and follow up, but I think he said they had that cam in a TT 408 that put down 600+ RWHP.

 

You don't need an aggressive came to make power with a turbo unless you are going all out. Mighty Mouse made 800rwhp with a stock cam in a 5.7. I was gonna buy a 212 218 cam from him. He checked it to make sure it was what he advertised and discovered someone sold him a stock cam.

 

The dream is to go all out, but I half tempted to go with the RADIX and call it quits since that seems like the most bang for the buck and time after all the tuning, stand alone fuel systems, and everything else that is cropping up to be in the top 10 nowadays. Heck, a year ago when Parish first got started, it all seemed too easy, but now I'm not sure.

Cheers to the big dogs!

 

Is that old cam going to be for sale?

 

I doubt it, I'd like to put it into my 5.3l which I plan on dropping into my CJ7. I'll let you all know if I don't.

 

OK, I got up with them (Roger) yesterday. If I remember correctly the 045 cam is the one in their TT408. He said that turbos prefer reverse spilt cams, but the 045 will work well, but if you're planning on setting any records, there are other grinds out there.

He also highly recommend the 066 for the lower 114 LSA because of the more more torque and it is a very well rounded cam that fits into many applications well. The specs are:

DUR @ .004" 282* / 286*
DUR @ .050" 220*/ 224*
LIFT .551/.551
OVERLAP 57*
LSA 114*

Rockers we also highly recommend too along with their springs, which I already anticipated.

I hope this is correct, there's some much info and options, that cams are a whole separte discipline which is hard to grasp quickly.
