id like to start a thread to post what you have found that makes this swap easier and potentially cheaper. so far this is what i have
1) fbody headers are a near flawless fit
2)i personally am going to run my th400 and ive found that this guy has explained everything

3) this adapter will allow you to run an aftermarket oil gauge for the lsx motor
http://www.speedwaymotors.com/LS-Ser...ter,20928.html cost $11
4) i personally am going to make my own motor mounts just because i have the steel a plasma cutter and a drill press. heres a link

I have read that the blazer and sub gas tank are in the rear of the frame this could be a bonus to guys lookin for more traction, I plan to run an efi tank and hopefully get a walbro to work within that fuel tank hat possibly a 255

I would like to find a cheaper alternative to the novak ac relocate system
also more options for gauges. both options ive found on these seem to be expensive and out of my personal budget goal.

How cheap can you do #3? Free if you have an 1/8"NPT tap.
On left is oil cooler bypass or right is original oil pressure sender - it was broken anyway. Both drilled and tapped.


If you are running the R4 compressor take a look at this

I have a blazer tank in mine, not the efi tank tho.... had I of known at the time I'd be doin an LS swap. I would've got the 87 tank... the tank is 28"x 28 1/4" x 10" deep. using the stock tanks straps and '86 sending unit, and external whalbro 255 pump....keep in mind I have a raised bed floor, so the tank is mounted up high, and not visible from the rear....also I welded a 2x4"x1/4" across the rear frame rails for some protection.....

and if using blazer or truck efi tank setup you can use 96-97 chevy c/k 3500 5.7 motor fuel pump. direct swap and plug in on older sender unit. 60 psi spec .

did some lookin for my setup and found

griffin 8-70008-ls is same size specs as big rad for trucks but listed for car's with auto trans and gas motors. with 2.750 core thickness and 1.5" inlet and 1.75" outlet sizes .

griffin 8-70013-ls is same size specs as big rad for the trucks and speced for the truck with auto trans and gas motor . with core thickness of 3.00" and 1.25" inlet and 1 5/8" outlet size's .

gets you both hoses on pass side for cleaner install and trans cooler gets moved to left is only thing.

I dont know why people keep buying all these adapters for the senders. You can use LSX factory senders to power the gauges, they work off of resistance just like the fbody gauges.....
