I'm doing a 9:7:1 2.4 and I'm wondering what cams I should use. I was thinking Gsc s3 or possibly s2.

 

Gsc 2 cams! Going to s3's would be pointless due to only being able to spin the 2.4 at 8,500rpms max..

 

I think you could spin the LR2.4 higher then 8,500rpm, youmust be talking about the 2.3

 

My 2.4 is going to be a standard not long rod

 

Gsc s2, kelford 272, cosi no going wrong with any of those cams

 

It will take some doing to make it idle correctly on an VIII but I would go with the S3 if you have any headwork done. The S2 will make good power on a stock head, like this-

I have fp 4r in my std 2.4 and its getting the job done and sounds great but cant go wrong with GSC s3 or s2 as John bradley has stated

 

The trick to getting large cams to idle is playing with the intake cam timing, btw.

 

What's the cost difference between the cams listed? I am going to do stainless standard sized valves and not sure which springs because different cams require different springs. With a s3 I will have to go with a dual valvespring for sure right? What is the most cost effective springs?

 

not exactly. you can use good single beehives like kiggly or gsc's.

 

S3's. You're moving a ton more air than you would be with a two liter. I think the S3's will be just fine. MRTALON20 made almost 100whp with s3's over his Kelford 272's on his 2.4 6262 set up.

 

Anyone else think the s3's will work withthe fp black well?

 

I'm definitely thinking about giving these a try for my fp black setup.

 

I would go S3s. You have a 2.4 so spool will be fine. You want the extra flow capacity in the higher rpms
