1994 blazer cpi to carb swap
 

Looking to swap cpi to a carb ... was wondering if trans and transfer case will still work or what I can do to make them work. THANKS

I'm no expert, but I think everything is too tied together for that to be a simple swap Seems like at the least you would have to come up with some kind of stand alone ignition. The transmission talks to the computer also, so maybe you need to swap in like a 700R4, or manual? Assuming yours has the 4L60E.

Keep in mind, I'm talking straight outta my rear end right now

Edit: why do you want to swap to a carb?

I am building an autocross vehicle .... just trying to figure out what easiest and cheapest way to go .... swap carb , trans , transfer case or buy high psi external in line fuel pump ... already have access to all parts but got a make sure trans is gona function as it should .... I mean it mite get into 2nd gear

You're going to autocross a Blazer?

Yeah nothing major just local fair autocross .... but need to know if trans or transfer case will work correctly after I remove stock fuel injection and ignition

What's wrong with the fuel injection? Without any engine modifications and upgrades, I really doubt you'll make any more power with the carb, and you open up a whole box of worms with figuring out the transmission and ignition

Little hard to answer without knowing what trans u have - A 7004R can be set up non computer A 4L60E needs the computer

Ignition is the easy part, it all goes back to old school without the hand full of sensors for the computer and has one switched positive wire to a old school HEI dist.
Bowtie Overdrives carries the kits - TV cable to carb, - solenoid's and such to non computer the trans if it's the 7004R

Yeah, I guess the ignition wouldn't be too hard to set up. 1994 would have had the 4L60E, though, I think.

You may be right.
My toy was built out of a 1992 GMC Jimmy and it has a 7004R
And I have checked into what he wants to do for my 4X4 RX7toy and if he buys all new parts for engine and trans he is looking at almost a Grand in cost
