Cam isn't too big for sure. Stall may be a little tight. the 80e 2.48 1st vs a 3.06 of the 60e will make a difference. I wouldn't worry about turning them over, though you should be able to, if your spinning you aren't going anywhere.

Yea but he had an 80e with his 6.0 and radix so that shouldnt be affecting what he feels because it didnt change

But with that size of cam even on a 408 you are going to be somewhat low on tq below 2000. But who cares about tq below there if you are stalling above that?

Hahah I'm not worried about being able to burn out for the sake of burning out , I'm using it as an indication of 2400 RPM torque I have. I did a few test launches last night in 4wd and they felt extremely weak.

Thanks for the ideas so far everyone, keep em coming!

Spark Plugs, I am amusing that you bought new ones, but were they the ones for NA or Boosted like you were used to buying? Just a thought.

oh thats bad. I say add 5* timing and see what happens. Your timing sounds a little low to me. Also try increasing spark dwell 2ms.
