So, who's going to run an LSx engine package in their 67-69 F-body ??

We are about to do an LS1 in my neighbors 68 F-body. What issues will we have with install? Will the A/C compressor in the stock location clear the right frame rail? Any and all thoughts will be much appreciated.

Engine mounts, transmission cross member, clutch hydraulics and the oil pan..... just for starters. The AC compressor will not fit unless you use engine mounts that shove the engine foward.... but that isnt the way to go about it either. There are a few different way to go about the AC compressor but there are some good ones and definately some bad ones........

There are a couple of ways to go about this but just about all the parts you are needing are available through ATS.

What is the cost involved with this swap.

minus the engine/tranny:

A) what are the ancillary parts costs

B) can't think of a B right now

harness work 300-500
pcm reprogram 100-300
or tuner software to program pcm yourself 500-1000
motor mounts 100-200
trany xmember 100-200
fuel tank efi replacement or conversion 500-1000
oil pan 200-500
new or shortened drive shaft 300-500

other possible needs:
o2 sensors &/or wideband for tuning

So, how does all this make installing a LSx less expensive than a conventional small block, again (not including headers and the air compressor issue)? Granted, you could install a SBC and still pony up all these cost with it, but you could also do it without a single one of these items depending on what you might already have.

Ok.... 365 days later.

71 to 28 for going with. I think this one is done.

i doubt a lsx engine is less expensive to install than traditional small block. it is prolly cheaper than traditional small block w/ efi.

Most of these things are required if you are going to do an efi conversion regardless of LSx or SBC.
Some of these things you would want to upgrade or replace anyway no matter which motor you put in. (ie: drive shaft, motor mounts, and tranny crossmember depending on tranny put in)
The savings comes in if you get a complete motor.
For example a 6.0l LS truck motor can be bought complete for $1800 used. This includes ECM so you saved yourself $1000 from having to buy a BS3 or FAST. And you are making 350hp stock.

Here is an article that did a comparison to building similar motors:
