Converting 72 Blazer to a BB, motormount/header questions ??
 

Just pick up a real clean 72 Blazer that had an engine/dashboard fire. I was told the engine was good, but figured it wasn't so I'm not terribly upset it needs an engine ............ I could easily just freshen the small block it came with and I'm sure that's the cheapest route, but I have a nice 454 with peanut ports that just makes sense for this truck. Couple questions I have before I dive in are .

#1 Do the BB POL mounts work well and leave the trans in the same spot as the small block did, or will the trans need some movement too ???

#2 Is there a header combo that works with the POL mounts, some say yes, some say no ????

#3 Is the truck really worth more with a 454 than a 350 ??? I figure the swap is only about a $500-$600 add on , being I already have the engine.

My plan is to build the truck super nice and keep it for a while, but eventually it may be sold off, so resale is important.

Thanks for the help !!!!

Personally I don't think a big block is an upgrade as far as resale value. Im not saying don't do it, just no value added, and possibly value taken away.

keep it a small block!

Thanks for the replies guys, I appreciate the advice. I've never seen any GM product worth more with a small block than a big block but hey, that's why I asked the question. I've also thought about maybe going LS as I've seen 5.3's going cheap but I have zero LS experience and don't really care to learn lol

Another question, What's the thoughts on air conditioning ??? Personally, I'll NEVER have the top on it so A/C means nothing to me, but I have to replace everything under the dash so aftermarket air might actually make it easier/cleaner looking????

I like the big block idea from an aesthetic view. Sure would look nice under the hood dressed up like 72 Chevelle.

I do not think you would get hurt making it a big block.

LS' do make them a little more desirable. But I think that is only on very nice Blazers.

All of the above is just my opinion. You know what they say about opinions.

I've decided to go BB, now just gotta make it fit lol

I started another thread on the engine and drivetrain forum about engine placement .........

Thanks !!!

Big blocks fit with SB mounts, they look nice.
