454 into a trailblazer

[xravenx]

well i'm just board at work and decided to make an account here and come up with some ideas of what to do with my 2002 rwd trailblazer...

though this may seem like a pipe dream and could be costly but one can dream

i was looking around and got the idea about putting a goodwrench 7.4 ltr carbed re-manufactured crate engine in a trailblazer rwd. probably get 12mpg but be a lot of fun with its extra power


anyone got an idea of costs for this to be done... the engine is 3.4k
and i can do most of the work for the install so labor cost are not relevant

Interesting swap. Why go with the carbed reman engine? For 3.4k you could have a 6.0 and 4l80 complete with tuning and a few other things that would be in my opinion better than the 454.

[xravenx]

yea a 6.0l with 4l80 would be a bit more affordable it seems... but how many 454 carbed TBs do you see out there. just thinkin of a way to be different haha.

Most likely never gonna do this swap cus id rather save for a 98-00 c5 for a summer car.

Thnx for the reply zeake

Is there even room in the engine compartment for a BBC in a Trailblazer?

[xravenx]

Prolly not (but maybe so, idk)... but you can always make the room with some modifications

isnt that illegal to do? i was always told u couldnt do things like that bc of some EPA junk

FWIW, in states that have emissions regulations you cannot put in an engine older than the original vehicle. If GM has not put a 454 into a light duty truck in any truck the year of his TB or newer then it is illegal. True, BB power is tough to beat but it sucks to own a vehicle that you can only trailer to car shows or dragstrips. I know your love for the BB, I want one for my 93 OBS truck, buy me a Musi/Edelbrock 555 with fuel injection and I'll put it in my truck and you can come down and drive it any time you like.

Maybe the states that used to allow older motors are the states that don't have emissions inspections at all now? Possibly the rule you mentioned always applied and I didn't know, because I've never had a fast car that wasn't available with a big block from the factory at some point. I don't know where the OP is from, but maybe he lives in a state that doesn't check for emissions.

But yes, it would suck to make the truck not legal for the street because of the motor.

A 555 would be nice. The way things are now it costs about the same to build any size BBC up to somewhere around a 572. All the parts are off the shelf parts and the prices are about the same for many different displacements.
