I have built a 1995 4-door Tahoe. I would like opinions and suggestions. What could be improved? What would you have done differently? Are the dyno numbers looking good? My objective for this build is to be a fun street machine. Not a daily driver and no track time. It's driven a few times per week. BTW, I average 12mpg city/hwy driving. I am pretty happy with this setup but I always welcome experienced opinions.

Honestly, there is not much that I'd change. I'd get a dyno run on a roller dyno, the hub dyno's are known to not show correct. I'd guess you're more around 350-375hp.

Looks like a well thought out and executed build. I agree your dyno numbers are probably lower than what it's making.
Only thing I'd do is add a wheel and tire combo. Right now it's like showing up to pick up a hot girl for a date and her hair ain't done. Not a deal breaker, we're still going out, but damn, why not finish it up....

I went through a handful of different wheel combos before deciding to stick with the OEM. I feel it perfectly compliments the 90's theme with the side graphics. BTW, those graphics are all real paint. No decals. It was a dealership option at Capital Chevrolet here in Austin back in the day. There is something quite 90's classic about those wheels. Like it's 1995 and I'm 14 years old again :)

I respectfully disagree. Nobody cool ran stock wheels back then, the custom choices just weren't as big as what's available now. Even if you're dead set on keeping the wheels, the tires are way too big for a period correct street truck.
In 95 I was 25 and still lived in California. Granted I drank pretty heavily and poked a lot of smot, but I can remember what the style was.
That said, it's your build, and as long as you dig it, that's all that really matters.
The graphics being paint is super cool, and I love the truck. I'm nitpicking because you asked for opinions.

I know what you mean. I even tried some 15x10 centerlines. Which at least here in Tejas, were the big rage back then. Especially with these graphics. But they poked just too much for me. After trying out about 4 different combos, I settled. I can't even think about trying more wheels anymore. Thank you for your input though. Anything you would change with the engine/trans/gearing though?
