    I believe he has a 465 gear box.

    It seems to me that they would swap.

    All Chevy v-8's since 1955 have the 90 degree bellhousing , all inline sixes since 1962 have the 90 degree bellhousing , the diesels and 90 degree v-6 have it too .

    Correct me if I am wrong, but wouldn't the bell from the blazer have the slave on the driver side? I know for a fact that the 88 up "K" series have the slave at about 5 o'clock on the passenger side, in order to clear the IFS diferential.

    Oops, re-read the question, and yes, the SM465 is the same between the 87 blazer and the 88 K3500. The 88 K3500 has a different top cover which relocates the shifter rearward about 5". Can get pics tomorrow if needed.

    if the 88-up has a 5 speed no it wont work as that tranny has a molded on bell.

    but some early 88-89 trucks had 4 speed 465 trannys. these might just work but i have not tried this.

    and as for the nv4500 no it wont bolt to a 465. bolt spread is bigger and center hole is bigger.
