Question about 1997 Chevrolet Astro
I plan to build an AWD buggy. From what i've read i need to select drivetrain as a base. I have a bench built 4.3L Vortec V6 from a S-10 Blazer, so I figured I would use that if i could. Because of the weight reduction, i was planning to use a mid-engine configuration if feasible.
Will the S-10 Blazer motor mate with the Astro transmission?
Will the Astro drivetrain handle the Vortec powerplant?
I've done it with VW motors for buggys but will a mid-engine setup work with the Astro drivetrain and V6?
Are there any special considerations to prepare for using Astro drivetrain?
Anything i'm missing?
All depends on the 4.3 your going to install. The transmission are the same, that both use the 4L60E. E being that the transmission is controlled by a ECM with the engine. If your running a Aspirated 4.3 and not fuel injected, your going to have to run a 4L60 transmission.
As for the AWD the new AWD system on the Astro works off the ABS system as it runs on 2WD till the PCM detects the lost of traction then the transfer case is activated by the ECM.
The earlier Astro and Safari AWD 1991 to 1994 had a true AWD and stayed active, but was not that great off road since it had a 40/60 split ratio front to back transfer.
Good luck and hope this helps.
