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

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.

The 6.0 LTR iron block weighs approximately 100LBS more than the aluminum lS1 block. The iron block can handle way more abuse the aluminum block can. Alot of the LS1 nitrous guys run the iron block for strength.

The obvious choice would be to go with the LSx

Unless you want to go 8's, there is no need for an iron block. What I am saying is do not have any worries about either block you choose.

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:

I am installing a ProCharged (D1SC) LS6 on the new hydroformed sub frame from DSE. My engine is being built by Golen Engine Service. I am purchasing all FAST equipment, which is almost a grand cheaper going through Summit, and I am using MSD ignition. This is not the cheapest way, by far, but it's going to run sweet.

Ok coming in late on the thread but just now pulled the trigger on an LS7 for the vert with a 4l60. Had to edit this because I just looked at my logged name. I've never been a "junior", somehow it makes me feel youthful, I'll think about that after my nap.

are you doing anything to beef up the 4l60e?

What mounting brackets are you using to mount the Procharger? Custom brackets or a production Procharger kit?
