JQ, take a minute to get the twist out of your panties, bud. I'm not trying to call out (or messing with) anyone in particular, you most likely just took that personally because you spray that 1st gen to death. I'm not interested in any of the builder's accolades, especially the length of time he's been a member of any forum. I am absolutely criticizing the build style of that truck in the video - stock everything, big charger, big timing, injectables. If that was a test run on the way to an efficient build then so be it, but don't use that as an example for someone genuinely asking for advice. Weston hit the nail on the head, that video did nothing towards pointing the OP in the right direction.
For the record, Scat and JQ, I am not disputing the power claim, and I have no idea what you are talking about. I question claims from time to time, as the vast majority of people on the Internet are incompetent. Wild claims abound, and I'm not the only one that calls people on things like that (especially around here). If you still feel wronged, feel free to fill out a standard "Hurt Feelings Report" and forward it to an admin.
OP, I'll try to bring this home and stop the derail. I'm not a pro, but here's what I learned in my days as a 1st-genner. The VE (in 12mm form) 12V is not known for fueling hard at high RPM or spooling big chargers quickly, so the idea is to fuel hard and get spooled down low because you have a short window in which to make power. I also learned that once you get over 400 rwhp, you start fighting tooth and nail for more power. The charger I ran was an HTT 62/65/14 and it was great, it spooled fast and the truck ran clean. Problem is, if that truck made 400 HP I'd be shocked. If you really want to make more HP (useable, efficient HP), you need compounds. One of the guys in this thread has, IMO, one of the nicest and best-built/setup 1st Gen trucks on the planet. It makes great, clean HP, and backs it up with solid time slips and a smooth dyno curve. That's what you should be shooting for.
What are your uses and goals for the truck?
