[QUOTE="sur_real1, post: 15678360, member: 42850"] In my honest opinion, you really seem to be right about where I would expect with your mods. Your cams aren't very aggressive, nor are they a matched set. Your headers are actually small for this motor, and probably your setup. (yes, I know there are lots of opinions about this, but these motors have enormous 4 valve heads that flow tons of air, more than any big block head). You have amazing, solid mid-range power, which is what you wanted in the beginning of your adventure. To make more power on these motors N/A, you will need to let go of the need for strong mid-range and focus more on the higher range. Which requires more aggressive cam profiles, a larger, quality header, and possibly more fuel or different fuel. There is a thread with a gentleman making about 477+rwhp with a similar setup, but with 1 7/8" headers and Comp Cams stage 3 cams and he spins it to the moon. Honestly, your setup now kinda lends itself to some boost and that's where I would go if you aren't willing to tear into the engine again. You're motor is strong and looks like it runs really well. Good luck! [/QUOTE]
