Pls give opinion on which Cam would be more responsive for street. Here are details:

2000 T/A
Forged 5.7
317 heads 9.3:1 CR
4l80E trans 3k stall
Factory exhaust manifolds
3.08 rear
STS style 76mm intercooled
60lbs injectors twin fuel pumps
running 8psi/15psi

Cam A) 0.472/0.479, 202/210 on 117

Cam B) 0.595/0.601, @.50 232/236 on 112

 

...no opinions? Just want to make sure it won't be a dogg off the line.

 

the smaller cam will run smoother and will be much easier on valvetrain

 

Thanks for the response...just did not want to be weak from stop light

 

An 03 ZO6 makes for a great streetable cam for a 346 CID setup.

 

The duration of cam #1 is too small and cam #2 is WAY too high. Dont run either with a turbo. You need something around 225/225 duration on about a 590 lift and 114 LSA if not more. I wouldnt go any more than about 230 for duration. Some like split duration but depends on whom you go with for a cam.

 

Agreed. If it's a rear mount and stock heads, I'd give atleast a 6* split to the exhaust though.

 

Thanks for the input...unfortunately Cam B is currently in (from before Turbo) and Cam A was a choice because it is free $. Cam B has good power from roll but will not spin INVO 295's from stop with out brake boosting Tune has been optimized but Cam B just not too compatible with this config. Will just have to chose battle situations carefully for now.

 

What is the duration at .050 on cam B? It's not 281/285??

 

You are right I corrected to show @.50 232/236 thanks...

 

I'd go with cam B on a 117!
