Escalade engine
I was looking at buying a good used LS1 motor for a project car but came accross the GMPP Escalade engine which is rated at 345HP and is very competively priced at $3790 see:
http://www.sdpc2000.com/catalog/120/...ate-Engine.htm
It has a 6 liter iron block and weighs just 65LBS more than an aluminum block according to GM.
I will be happy with about 400+RWHP so I intend to swap out the cam initially to achieve this level of performance with a slightly better redline of 6200RPM hopefully and as time progresses perhaps use AFR heads to bump up power some more.
Questions:
1) Is this engine a viable proposition for my purpose?
2) Is it going to be able to withstand the higher RPMs (briefly) without a head swap?
3) Is 400RWHP achievable with just a cam swap?
4) What will I need to do for an ECU/harness (basically a hot rod application)?
5) Will I need sophisticated fuel remapping for the cam swap or is the stock ECU able to handle the addition of a new cam?
6) Do you guys have a better solution/ideas?
Thanks in advance
2) under 5800rpm unless u change valve springs, which i hope ur doing with a cam swap...
3) u'll need a big cam, but can be done, most likely 380-390 with an auto trans
4) 1 of the computer companies who specialize in FI engines in older cars... can't think of a name now, guy i work with had 1 made for his '55 with LS1/4L60e
5) will need some tweaking, depending on cam size, trans and other stuff
6) sounds good to me
Thanks for the information - the engine is going into an ULTIMA GTR.
I want to start with around 400+ RWHP until I get familiar with the car. I am an old Porsche guy (no flames please) but built a few small blocks about 15 years ago. Still love the chev small block; I think the GTR is the perfect chassis for it.

The iron block is somewhere between 65lbs and 80lbs heavier than the LS1/LS6 block.

Thanks for the comprehensive reply - it will definitely help me make the correct choice for an engine purchase.

BTW, there is a vid in the multimedia secton of an Ultima GTR with a GM small block doing 0-100-0 again in around 10 seconds!

I would go with the 6.0 Iron block, you can't believe how much power you can into this motor, without problems. It's well known for it's ability to handle enormous amounts of power, and if just want to keep it stock, it's life expectancy would be superior to an aluminum block engine. They are very smooth compared to any of the smaller Gen 3 engines. I think the 6.0 stroked to a 408 is a master piece to put in your car or truck. Give me a call if your interested in one of my 6.0's 817-988-4760

Thanks - I will be calling you soon
4) What will I need to do for an ECU/harness (basically a hot rod application)?
Speartech can make a harness and has decent prices.
5) Will I need sophisticated fuel remapping for the cam swap or is the stock ECU able to handle the addition of a new cam?
A dyno tune would produce best result. If your not close enough to someone for a dyno tune, you could get a mail order tune.
Thanks in advance[/QUOTE]
345hp is at the fly not the ground so they say. I had a budy do 375 at the rear though his lq9 with a cam only.
You will need to have the PCM tuned.
My buddy was spinning his lq9 to 6500 all time so i would asome that you could do the same.
