Have you run any of these with a stall of 3k or higher? If so which model? All the models just say the gross vehicle weight and btu's, this tells me nothing. I know the gvw of my car but dont know how the stall speed affects the heat generated compared to gvw. Thanks
Yes. Of my current cars, I've got an M7B on my '68 w/ 340, 727, 9.5" converter. It works great. My big block '66 has the H7B, but it's not on the road yet. My old 408 had the M7B if I recall and it also worked perfectly.
If you have both, a B&M and TruCool cooler in front of you, you won't tell a difference. They're the same cooler, just branded differently and usually the Tru-Cool units will save you a few bucks. Those stacked plate coolers work very well.
