Great idea but I'd do a 6.0 instead for the added torque. With the price of gas these days, it would pay for itself in a hurry.
How Are The 6.0's On Gas Though?
You should get 14-16MPG in that pig.
Alot Better,i Wonder How Easy They Are To Find ,i Need To Start Looking,i Wonder How Many Extras Ill Need To Get Together To Do The Swap?
I Get 7 Now 4 If I Use The A/c With My 4:10 Gears
I Would Do Away With The Coils And Do A Distributor Kit They Have For The Camaro Ls1's In The Gm Performance Book
Ouch!
Buy a complete pullout with everything they'll give you. Harness, accessories, hoses, belts, PCM, flywheel, air cleaner assembly, exhaust and flanges minimum, starter...anything already bolted to the engine.
Then you'll need the harness converted, PCM setup with a hotrod tune, motor mount adapters, electric fans(optional), electric fuel pump(if the V8 isn't injected and can't push 60 PSI of pressure)...
Check out the OBS to LS1 conversion topic to see an overview of things you'll need to do during the conversion.

If It Will Work ,convenience Of Not Having All Those Coils,a Distributor In The Front And A Carb,less Wiring Issues,but Ide Have To See If The Plate Would Fit The Front Of A 6.0
