88-98 LS Motor Swap Pics......

CTS-V or a Hummer H3 oilpan may work better for you.

Add Colorado/Canyon to that too, same as the H3

The only thing I could see there is that if the H3 pan cleared, it would be just barely, and with the f-body pan, you will have plenty of clearance layed out.

Are the 1" set back plates absolutely necessary on a 88-98 Truck? I have the regular plates that I used on my 1981 K5 Blazer 2wd that I am going to use in my 1994 Crew Cab project.

No they're not necessary. I used the standard plates for a while, only changed to 1" to gain some header clearance while the engine was pulled.

You can't go wrong with the F-body pan, plenty of clearance. The LS2 corvette pan may also be worth looking for.

using the 1" setback adapters, the existing transmission can stay in it's original position? that's what i've gathered on those setback adapters.

I can't say for sure on that, I've only had transmissions with cable shifter linkages. When swaping into a vehicle with the rod style linkage your positioning is gonna need to be fairly precise.

I've been trying to research all I can on these adapter plates, info I got is that if switching from regular small block to LS, the 1" back plates compensate for the differances in block dimensions to place drivetrain in the "normal" position foryour truck. Also, there are different opinions on adapter plate thickness. One manufacturer says anything thicker than 5/16" will raise the height of the engine thus changing pinion angle and possibly creating trans. tunnel problems. Maybe someone here can straighten us newbies to the swap club out on the subject. I'm interested cuz I have an LS2/T56 combo to drop into my '93 rcsb 2wd. ALSO, I have heard lots of good about the Shoenfeld longtubes, they look good and the price is right.....just wondering about clearance, performance and what the easiest way to go from their 3" collectors to a 2 1/2" system would be...........what is a low restriction/good sounding muffler????? THANKS !!!!! Almost forgot, GM has an all inclusive pan kit for swaps, they advertise it for LS swaps to older cars such as Nova's, Chevelles, dimensions are close to a stock truck pan........part #19212593.....$153
