can I bolt a LT1 out of a '96 caprice to the 700R4 in my '90 RS?

 

yes

 

Yes it will bolt on. Making it work right will require you to purchase about $250 in parts. Ranging from detent cable, intake bracket, throttle body add on bracket, Tcc lock up and vss things. All this of course for a proper swap.

 

Another reason why the 4L60E that comes with the LT1 is a better candidate

 

LT1's came stock with a 700r4 in 92-93

 

His 96 LT1 came with a 4L60E

92-93 LT1s came with a 4L60

 

well this is prolly going to be digging into my pockets wayy deeper than I can, so looks like I'll just have to find a regular 350

 

700r4 and 4l60 are the same thing. It may have been 'called' a 4l60 in 92-93 but its the same transmission.

To answer the op's original question: Will a 96 LT1 bolt to a 700r4 - YES

 

Why not pick up a L05? Upgrade the cam to a l98 add some 1.6 rr and have a tune sent to you? Would of been my route if I stayed with gen 1. Tpi is nice but even 305s can go for 400-600 and l98s I see go for 400-750. This for good ones (under 110k).

 

What are the parts that cost the most? I figured you just needed the stock cables and such from a 93 lt1 fbody and the stock 93 throttle body? What are the proper parts for it?

 

You do but finding thpse parts for me and the past 3 weeks have been impossible. Next up are aftermarket offerings. Throttle bodys range anywhere from $130-$200 and even stock ones I have seen go from $75-$125.

 

Oh wow. I've seen those parts literally given away for free locally. Wish I had known..

 

Keep in mind this is only 92-93 Lt1specific items.
