Folks, I'm primarily active on the pickup side of the board but a buddy has asked me to help him "recover" from a bad engine swap. Basically, a "friend" of his traded him swapping in a butchered "Corvette" 327 for the stock 454 in his '74 automatic Blazer. Needless to say, it's a mess - welded up PS bracketry, etc. We have the 327 pulled to see what he can get out of it, but he wants to put a mild 454 back in. We're starting to plan that engine build now, seeking a rebuildable core.

I'm completely new to Blazers, so I'd appreciate some broad guidance as well as a few specific answers:


Are Blazers the same as P\U in requiring the proper "towers" for BBC vs. SBC? If so, are the BBC towers available?
I ass*u*me that a different bellhousing/flywheel/starter is required (TH350)?
ALL the bracketry for the alt and PS are missing - is this stuff avail aftermarket either stock or upgraded (March, etc.)
Does any have some good engine bay pictures with a 454 in a 1974 Blazer?
Anything else I should be thinking/worried about?


Thanks, folks. I'm sure I'll have a ton of questions, so I'll thank you in advance for your help!

Kinda surpised with the lack of response here...

The blazer is same as truck in everything except rear driveshaft length. Big block or small block both take the same trans, mounted the same way using the same (i think) crossmember. Flywheel is different and starters depend on the year, some are the same, some are different. Best bet for accy brackets is a doner truck. The only thing to be concerned about is a stock th350 holding up to a big block. Th400 would be a much better choice.

Thanks! Looks lik I'll be building a 383 for him. Would be great to have some underhood pics!

I have an 84 Burb with a 454 in it. Maybe it will help out a little bit. I'll try to get some pics of it over the next couple days.

A 383 will is an awesome choice for the Blazer too. My friend has a 77 with a 400hp 383 in his K5.
