Sorry, I haven't checked back in for awhile guys. First of all when I said I wanted to make around 350-400 rwhp I'm not expecting "increased" gas mileage as someone said I just need a build that is gonna get gas mileage that is "acceptable enough" to be able to use as a daily driver and not just a race/weekend truck. Really it would be nice to still be able to get 10-15 mpg. I know some are gonna say that's impossible but I'm thinking if I went with a 390 stroker kit($2,400 for the good one plus machine work), a set of eq ported and polished heads($1,500), and something like a turbo set up which would actually help improve efficiency and power(around $3,000 +/-) that it would be easily achievable. I would also probably throw on an aftermarket intake, small/efficient cam, and 1:7 roller rockers. Someone was also assuming I have an automatic transmission but i actually have a manual nv3500. The only thing holding me back is being able to come up with a huge amount of money, but I could probably just make payments every month as someone mentioned. When I said 400 rwhp I was just stating an estimate but what I really want is big seat of the pants horsepower. I just want a daily driver that will still whoop some newer stock muscle cars butt, yes I understand this is hard to do. From what I have read my 96 club cab truck weights around 4,000 lbs. Isn't that around the same weight or just a little more than these newer muscle cars ?
