So here's a funny story about driving like an old lady…
Anyone who reads my tech stories in the magazine knows that I like to do my own work. There really isn't some deep-seated distrust of others or anything like that, I just like a challenge and love learning new stuff. That said, I try to get my hands dirty whenever I can. It's a love for the hobby that I can't deny.
There is a problem however; when something breaks, I have to fix it. That's not always fun.
And so, fast forward to the point where I've fired up the supercharged LS327 in my '68 C10 and I'm tooling around the city that surrounds our tech center. I've checked the oil level at least five times, the coolant is topped off, and everything seems to be working as advertised. There's only one problem. It sure doesn't drive like a truck with a supercharged LS …
This goes on for a couple of days until I'm driving home on the 405 freeway one Friday afternoon when a thought crosses my mind.
"I haven't pushed this thing past 2,500 rpm."
Remember that bit about not liking to fix stuff when it breaks? Well, it seems that I was using the old "kid gloves" approach to my hot rod truck in the hope that I wouldn't hurt anything. Time to buck up and have some fun!
So, I decided to take an exit near my house where I knew there was a nice, open stretch of road with a 50-mph speed limit where I could let the motor wind up a bit, at least in the first few gears.
As it turns out, I found that powerband I was looking for. In fact, it was there the whole time; I just had to look for it. And when I found it, it was like getting hit in the face with a frying pan. That sedate LS truck motor turned into a fire breathing, hot rod mill once I put my foot into it a bit and let her rev past 3,000 rpm. I now know where in the rev range the blower makes boost and it works awfully well if I do say so myself.
I'm glad I "manned up" and beat on the truck a little bit, after all, that was the whole point of the build. I wanted to be able to go out and have some fun and not have to worry about breaking things. So far, it seems like it's all going as planned. I have over 300 miles on the C10 over the last few weeks, with a couple of dyno pulls thrown in for good measure. I'm saving the numbers for when we cover the engine specifics, but it's looking very good and we haven't put much of any boost into it yet. I think you guys will be impressed with the figures once it's all said and done, and from a truck engine no less!
And the moral of the story? Go out and have some fun, breaking stuff is okay sometimes!
