• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

power for the diesel

I am just getting into IH trucks. Moving over from the muscle car area. I drove a nice looking mid 70s diesel IH the other day but it really had now power at all. It looked mean but lacked the performance that its looks had. I research and saw they really only had about 90 wish hp and also about 190 of torque I think. I started thinking about it and yes as a kid i remember them lumbering around as the gained speed.

Am I correct on these not having a lot of speed and power or was there something wrong with this one?


The naturally aspirated ones are especially turd like. The turbo versions are a bit better, but you're talking mid-70's small displacement. Basically, the dark ages of diesel engine technology compared to modern engines. The performance is just never going to be like a Duramax. You kinda just have to learn to enjoy it for what it is and take more time, or do a drivetrain swap.

I've wanted to put a VT275 in a Scout for a long time. They are becoming affordable now that CA has outlawed pre 2010 diesel trucks.
