Hi everyone, just joined the site. I have a 1989 Chevy K Blazer, and the engine needs work, but the truck is 20 years old, so, lol. I have a 74 Olds 442 which has a 455 rocket, and I have contemplated putting it into the Blazer. From what I have been seeing, it is possible, if I use the motor mounts from a 6.2 liter chevy diesel. The 442 has a TH 350, so this engine is not the stock engine. The blazer has a TH 350 also, but has been rebuilt. So I guess another question I would have is would a 89 TH 350 tranny bolt up to an Olds 455. The engine has headers, so that will be another issue in itself, lol. Have a good night.
