Interesting. One thing I do notice it doesnt seem to pull at the upper rpm range. My NA motors always like 7400 rpm. This flat tappet and turbo deal doesnt seem too.

Now is that because of the cam or because of timing so far retarded. Needless to say on the rev limiter by 1000ft at 7400 so needs a gear change. Question is 4.56(which I have on the shelf) or 4.30 or 4.10

I will also play with the converter next year. Nice to have a guy do my stall changes for free...
