I'm boosting a 5.3 with a typhoon intake with a garrett gt4594. I want somthing mild. Titanium valves, mild port. Going in a 240 with a full manual auto.

Duration at .050 intake 215.0,exhaust 219.8 Valve lift w/1.7 rockers intake 0.598, exhaust 0.551 lobe separation angle 117.8

please tell me what you think.

 

diffentley a turbo grind cam, yeah looks good. the only thing i don't like is the titanium valves, atleast on the exhaust side. i would change the exhaust valves over to stainless, if it was my motor.

 

why on the valves?

 

high exhaust temps and titainum don't mix very well. the life expectancy of the exhaust valves will be reduced.

 

good info thanks, hows the valve overlap?

 

looks fine.

 

I think it's -18.2.

 

got a copy of the cam card close to you? i will tell you what to look for.

 

no, I dont have the caRD. I found a calculator online that used duration and lsa....

 

those calculators are close enough, nothing beats the actually card, and then degreeing it in to make sure the the open/closing events are where they need to be.

 

does anyone even make titanium valves ?

 

Delwest, nascar stuff.
