Need some engine advice and suggestions...

[Hart_Rod]

I finally got my chassis and suspension squared away, now I need some suggestions/advice from all you motor gurus, . I'm trying to get my truck as streetable as possible (I drive it to work several times a week, ), yet still be very "salty" at the strip.

Here's a link to the chassis/interior updates:

First, let me say that I didn't build the motor or transmission. Here's a list of what I have done myself or have been able to determine that had been done by the previous owner. The motor was built by T&L Engine Development out of North Carolina (http://www.tandlengines.com/) and appears to be very well built. I have a lot of paperwork so I'll answer any questions the best I can. What I'm looking for are suggestions or recommendations about what has already been done or what should be done in the future to make this setup as efficient as it can be. Here's a list of what I know:

They dyno sheet I got shows 631.1 TQ @ 4900 rpm and 622.7 HP @ 5400 rpm. The run was only to 5500 rpm. Supposedly it's built to go to 7500 RPM.....

This is my first really high performance engine (and supercharger) and I want to make sure I don't break anything because something is incorrectly setup or something is missing. I'm open to any suggestions, recommendations, and/or changes to make this a strong running combination. Fire away at what you think is good, bad and ugly.........
