So I'm looking to pick the perfect cam for my application, my specs are as follows
- Forged 8.5:1 bottom end
- AFR210 heads
- LT4 intake
- Vortech T trim should make about 15-18lbs boost

I want a cam that will make power through the entire RPM range

I was thinking 230/242 610/615 on a 113 LSA

a friend has suggested 218/238 595/610 114LSA so as not to bleed off boost

any suggestions and reasons why would be great, thanks

 

On a 97ss 383 - ATI D1 pulley 7.6 to 3.4" dia. 15+ psi rated. AFR 190 heads with LT1 modified intake. I'm running a cam motion cam with the following specs...
231/240* @ .05" 114lsa/ .538 - .558" lift/ 110* CL intake. rpm 3500 to 6800.
Makes good power. This is my 4th cam. I had a comp with 218* duration, but it did not have as much rpm potential.
The cam has about 8* overlap which I think is all the obd2 pcm can handle. I have it running very good now with my tune on LT1_edit ver 2.2.
I'm running 72# injectors with large intercooler and h2o-methanol injection.
I have hard piped all suction and pressure sides which made huge differance in performance. Hope this helps. B,

 

I notice a lot of members here run with large duration on their blower cams. You are right about too much overlap since you'll be forcing air/fuel through the exhaust. The cams for blowers / nitrous need a bit more on the exhaust than N/A to help with the added combustion.

 

I would call Brett. Alot of guys have good luck with a 224/236 114lsa. I went a little smaller for low end torque 224/230 113lsa.
