For the time being Im going to get as much out of the Vortech S trim as possible since there is no upgrade program for the T trim. It would cost me 2K to "trade" up to a T trim. So when I get the house and wedding done I will be going with a turbo to feed the new 408.
For now Im going to get what I can out of the 5.3. Im going with a 212/218 low lift cam and am not sure about pulley sizing and shift points.
The max impellar speed for the S trim is 50K but many have spun them 7-10% over with no probs.
With the 3.12 pulley and 6500 shifts I would be turning at 56250.
If I went with a 2.95 and 6000 shifts I would see 54915 and see more boost sooner. Which do you think would be the better setup and why? Will that cam make that much more power at 6K+ to make it worthwhile?
Opinions are welcome too. Im looking for the most fun, not necessarily the fastest time as this is just to bide time.

 

2.9 and the lower shift. that cam will run out of steam right around 6200 so why push it, plus give you better throttle response and hopefully you willhave less lag with the smaller pulley.

 

2.9 and a lower shift point. As long as your belt won't slip. I think it's easier on an engine to get 30 rwhp with more boost as opposed to 30 more by spinning it higher.

Plus, your drop to rpm after a shift will be roughly the same regardless of the shift point because of your stall. So the 2.9 would be putting out more power at the bottom of a shift.

 

Thanks guys. That was what I was leaning towards myself, I just wasnt sure if there was that much more power to be had in the upper rpm range.
