Started this project months ago, but just got around to posting. 1955 Chevy on a 2006 Chevy Trailblazer SS chassis.

That worked out well, and that dash looks great

[Fast Chevy]

Thanks, actually using firewall and floor pan worked out good for lining everything up. I did have to remove about 11/2 “ off each end of dash though. Added a few more pics. Moved bumper back about 2” , didn’t like how it stuckout. Console went in good, used back part for interior fuse box.

Looking forward to updates

I think you have the right idea, this is a cool swap and will make for on every nice 55'

Stance with new wheels n tires.

[dsraven]

what size of tires did you end up with?
looks good.

[Fast Chevy]

Ratio out back is factory which I believe is a 4.10. Haven’t driven it yet so don’t know about what effect changing tire size will have. I need to finish bed n interior but it will slow down now that weather is getting nicer. I can take a better photo of front n give u some measurements if u like, rear won’t matter cause bed not set where I’m going to leave it.

check your pm's when you get a minute. s'mores come first, lol.

[dsraven]

are you using the original bed with the wood floor or changing it up to something else, composite, steel floor? have you got the bed mounted yet? gonna use the trailblazer spare tire under the bed or run without a spare maybe?

[Fast Chevy]

Probably going with an oak bed since I have the oak( make furniture too). Don’t have bed in final location yet but close, probably put spare tire back on but it depends what I come up for the rear end, thinking about bending some metal in a quarter circle underneath tailgate n then mounting my taillights in it. Still up in the air on it.

I found on mine that the 235/60r17's wouldn't quite fit under the box with the original spare tire carrier because the truck sits pretty low. I pinned the suspension at ride height with the original envoy body on top then stripped it off and put the old truck cab on top of the frame with the rockers about even with the bottom of the frame. that way there is prolly no surprises if it were to bottom out on speed bumps etc. the floor in the truck is about 2-2.5" lower than it used to be. is that roughly what yours works out to? I have the spare tire style rear fenders so will likely just use that method. it would be interesting to see the tail light system you have planned. I see you recessed your firewall a bit. does that affect the steering wheel depth noticeably?
some pics of your dash would be nice. you made that look awesome. mine is shortened and mocked up but not finished yet. looks about the same a yours for fitment. I will likely get another whole dash because this one is from a chain smoker's vehicle and the smell just doesn't go away. being a non smoker I really notice it. mock up is good anyway. get this one right and then copy the new smoke free one.
are the ss heels 20"? I like the 17's you have picked out.

Wow, that's slick!

Nice work!

[mongocanfly]

Nice!!!!!....

[Fast Chevy]

Thanks Greg,

Man, that turned out great!!! I'm impressed with the number of things you fit under the hood!! I was running out of room quick. Well done. If you have them, post detailed pictures so we can all study.

[Fast Chevy]

Didn’t take alot of detailed photos, but if there is something u really want to see let me know n I’ll see if I can take a photo of. I removed alot of the 55 metal wheel well to give me more room under the hood n replaced them with the plastic wheel wells from the trailblazer.
It worked out pretty good, had some cutting n fitting to do. I have tried to use as much as I could from the trailblazer, even utilizing the SS n Chevy emblems instead of buying the expensive 55 emblems.
Jeff

[dsraven]

looking good. what does that dash look like when it's all done? did you have to fill in the end vent and headlight switch due to narrow cab?
did you set the firewall back from the original 55 firewall location? kinda looks like it with the fillers at the top of the firewall. it came out really nice anyway, great skills you have there.
just curious, with the smaller OD tires, whats the cruising rpm on the highway like? I/m thinking of using 235/60r17 or 235/55r17 just to keep the rpm a little lower at highway speeds.
nice job on fitting the stuff under the hood as well. my battery will live under the box.

Very nicely done. The narrowed dash looks factory. Did not read where your wheels came from. Choices are definitely limited. When I studied putting the entire floor and firewall in, it felt like I was running out of cab room to put seats in. Stayed with factory '59 floor. Will you be using smaller than the TB SS seats? Mine came out of a Saturn Vue. Mini Cooper seats looked promising too. I lowered the body onto the TB frame as low as I could reasonably get it. As a result, my front tires rubbed the top of the wheel opening when I was reversing and turning and when I was going forward up an awkward driveway ramp. When I replaced the front strut assemblies, it all stopped. I must have gained a little height with the fresh springs. Any bigger wheel/tire combo on mine would have not worked.

Dash ends aren’t finished, but if I were to do it again I would cut out 1” from door where the dash meets it, like some new cars. I set back the firewall about 3/4” so that dash would fit better n I could give the firewall a more finished look( needs painted yet). I have not driven it on highway yet to check rpm but I did do calcs n Rpm will go up. Wheels r Moto Metal from BB wheels, not much choice for trailblazers, they were on sale, with tires less than $800. I’m using factory seats, alittle tight, but I’m not planning any long trips with it n using them everything just plugged right back in n I’m not that tall (5’9”). If I were to do the cab again I would have added 6 to 8” for more cab room. I believe Raven is doing that.
All n all was a pretty easy project. Thanks for your interest.

here is a thread for a stretch cab on a trailblazer where the doors are extended instead of extra behind the doors. it would look better than adding the material behind the door if not going for enough stretch to add a window. my opinion only. the issue becomes the door skin I would think. the door skin is tapered on the body line front to rear so you may have to fab a new skin. not the end of the world though. the rest of the door stretch would be pretty straight forward if you have the skills to do the other part of the cab and frame swap. haha.
I cut my dash on each end but then the vents need to be made smaller and the headlight switch needs a revamp. not that far yet as I have other stuff on my plate right now.
