Re: thinkin of swapping in a sb 400
I built a 400 for my blazer and loved it. I know lots of people with 400s in everything from race cars to daily drivers. Nobody I know has had any bad experiances with them. A good friend of mine built one for his late 70's 3/4 ton tow rig. All he uses the truck for is towing. I have heard of them having heating problems, just like many other people have. I just haven't personally known anyone who has had problems. If I am going to build a small block, the 400 is MY first choice.
