Default Which Kelford Cams? (stroked ej22t bw s363)

I'm building a 2.35 stroker ej22t setup currently. Already have Wisecos, new hardened STi crank, ACL's etc. and have a set of Carrillo pro-sa rods on the way. I will running a BW s363 .88 single t4. Going to find an n/a manifold and I'm looking for high rpm power. I need to be able to rev at least 8k (and make power, I don't want the power falling off at 7k and just making noise at 8). So I'm planning on running a pretty aggressive set of cams (don't think my BC 280's will get me there).

I was first looking at Kelford 199-G (282's actual 240 duration). But with the STi crank I'm thinking it would be better to run Kelford's STi cams... say the 199-D's and just plugging the AVCS holes. Am I over camming for a theoretical peak power in the 7500-7700 or higher range and good power to 8000-83000?

I did a light port and polish on the heads, probably will be running Supertech valves (stock size). So I'm looking to the turbo, cams and intake to move the powerband up top. Looking for some thoughts from those who have experience with Kelfords? Thanks for sharing your knowledge guys

This isn't exactly my department, but I would recommend larger valves for higher flow at higher rpms, also porting out the heads more.

I think you may need to read up a lil more ... The crank has nothing to do w/ the type or size of the cam you should run.
If you plan on running AVCS then yes,the Kelford R 199-c cams are a good choice.( or R 199-x?)
Otherwise the 199-E or 199-G are more applicable .IMO
I'm sure others will chime in .

when I got my kelfords I called and talked to the owner Kevin Ban himself and told him my setup and what I wanted to do and he made me a set.Just email him your info and goal and he will hook you up with the right cams for your setup.

Actually I did some research that suggested that stroke length can have an effect on cam choice...

News to me, but that 's why I'm asking...

Port velocity > CFM, but you know that!

199-E's are a good place to start for specs on a 75# turbo, but I'm not sure if you'd want something with a higher lift (K's).

Kevin emailed me back yesterday, said with my setup he would lean towards the 274/274 (234/234) w/ high lift (the 199-K). He thought the s364 .88 t4 isn't enough turbo to utilize the 199-G cams and that the K's would provide power up to 8k. That part about the turbo surprised me, that's a pretty large snail, but I'll trust the guy to know his camshafts!

I wonder how much more aggressive these k's are compared to BC 280's (actual duration is rated the same, and the BC's have less lift.) If I'm going to change cams I want something more aggressive and more rev capable than the BC's. Even though the duration at .050 is rated the same, my guess is the k's are a fair bit more aggressive!? And of course they have a fair bit more lift....

Higher lift even with your stock sized valves was a surprise, but like you said, he knows what's up.

Yea, I'm usually a fan of higher duration - when looking to push the powerband to the right), but I have to assume these cams with a pretty big turbo, good intake manifold, proper cam timing should rev out pretty well.

Anybody have an opinion on GSC s2's vs. these 274 199-K Kelfords? I've been leaning towards the Kelfords hands down, just thought I should ask in case I'm missing something...
