Re: engine power which is the max approved force for the blazer K5 4x4
my '72 had a 383 stroker at 400hp. You wouldn't know it from outside the headers and intake. I had to replace it with a crate 350 at 300hp. Again, it still looked almost identical to factory. Do you have any obvious modifications? By the engine #, what is the HP rating? Of course, a restrictor plate could easily drop your power, making any mods merely cosmetic. The SPID on my truck simply lists a 350 CID engine.
