straight six performance
i have a 270 GMC straight six that runs great, but its hard to keep up with the v8's, i NEED more power, how and where??!! i've looked all over the internet and i've only found one place that sells some stuff and thats Clifford Performance, my 59' has the stock 3.91 gearing if that makes a difference
THANKS!!!!! |
