TSP 228R right for me?

I'm an M6 guy but I'll take a stab at this. 114 lsa and go a bit bigger on the cam. The 323's and stall will be a big factor in your cam choice. I'm sure an A4 guy will chime and help you out. ttt

It is a good thing that you already have the converter portion out of the way. Are you planning on heads in the future as well? You could probably get away with a tighter LSA like a 112 but I think that you would like having a more broad powerband throughout with the 114. Cam looks like it will be a good midrange performer with still some good low end power. Which is also somewhat dependant on your LSA choice as well.

that is the cam i'm running with a m6.it drives well now that it is tuned alittle better than when i was cam only but tuned properly it will be a great dd cam.mine is on a 112 though but it topped out around 6100-6200 rpms.

I have this cam on 112 with M6. Mine pulls strong to shift point @ 6600 rpm. See dyno #'s. This is with stock pulley and intake/tb. It has ran 11.8's @120 full weight car eith 4:11's. I would say get it and don't look back. Dyno #'s don't win races.

Get the 112 and for 150 extra you can get a mail tune from TSP.
It is a no split cam, on XE-R lobes, easy for tuning and idle (even) 112.
I would run 7.425 pushrods with that cam, 918's will be fine.

My .581 XE-R was .09x smaller which translates in .045 longer p-rods needed (7.445).
The closest without going over is the 7.425
7.40 will be noisy and too light on the preload.
Basicaly when doing a cam swap (stock gasket and stock unmilled heads), you should increase the p-rod length by the amount of the difference in radius of the new cam base circle:
Stock base circle 1.55
Stock radius .775
so extra p-rod length = .775 - (new cam base circle/2)
I hope this makes sense.
