What do I do now (engine swap)?

[Gary]

Ok I got the 85 home, it's a real beauty (see sig)

Now the "dilemma" the 305 just ain't cutting it for me, it's not very strong and I want to replace it.

Now I got that 72 sitting there with a pretty strong 402BB and it's likely gonna be a year or more before I get that 72 done so that motor's just gonna sit mostly, should I:

A: swap motors, then when I'm done with the 72 either swap back or just get a monster motor for it
B: leave the 72 alone and just order a nice crate SBC for the 85 truck?

The 85 has a 3 speed auto (TH350 I assume) and I really want to swap over to 700r4, the 72 has a 700r4 and I love it, I'm hooked on the overdrive I must admit.

So what do you think I should do and why? Right now I'm leaning towards swapping motors and getting a fresh 700r4 for the 85 from bowtieoverdrives, if I buy a motor the pocketbook won't really have enough room for a new transmission TOO but if I just swap motors I can get that fresh 700r4 too.

The 72 is only gonna be driven around to get worked on for quite a while to come so that tired 305 will be fine for that. Frankly so would the TH350 but that truck already has a 700r4 so I ain't taking it out.
