    Anyone tried a 4BT (Cumins) conversion for a 6.2. I hear that the 4bt is a direct bolt in and was available in chevy step vans. Its a turbo 4. There is also a 6bt which is a turbo 6 and it should fit also. Anyone try this? I thinking about the 4bt when my 6.2 kicks it /forums/images/graemlins/frown.gif. with the turbo it makes about the same power, less weight, more mileage. /forums/images/graemlins/smile.gif
    Thanks Guys

    I havent personally put a 4bt in, but if you can get the motor mounts and brackets and such, it should be a direct bolt in since the P30 Step Van chassis is the same as any other Chevy truck chassis. Its 105 hp and 300 or so ft lbs or torque, but can easily be brought up beyond the levels of even a turboed 6.2 and get better mileage to boot.
