Hello all,
I have the lovely truck listed above that I am planning to mod up a bit here shortly. I was wanting to put a LS1 that came from a 2000 camaro SS, but wasn't sure about a couple of things. Does out intake bolt up directly to this engine. Also, i wanted to supercharge this engine, what supercharger would i go with the one for the original truck engine or the year for the LS1 camaro?
thanks,
Drop it in with the truck accesories and intake, and truck supercharger
Yessir, it's a one for one swap. You'll need a tune update but it will be worth it.
Oh ok u meant "drop". Lol. So use the 5.3 accessories brackets and intake on the ls1 and order the 5.3 supercharger. So the ls1 heads have the same bolt pattern as my 5.3?
yep. The only real visual difference from a distance will be the color of the block. And up close the head casting numbers.Quote:

Absolutely. If you got the extra cash that is. Swaps can sneak up on you money wise. IMO If you have extra money, do a cam swap while the motor is out of the truck. Youll need new valve springs, pushrods, tune. I would also get a new timing chain. LS2. And some Long tube headers. O and a 3k+ rpm stall. If you buy used you can really save a lot of money. With all those mods, you will be haulin some glute.Quote:

Long tubes diffenitely, I was already going to order that. Tune but of course my good man. 3k stall, can I run a 2500? The tranny shop rebuilding a 4l80 I got will give me a 25k for free but another 500 for a 3k.
All depends on your needs. If you want lots of lope, stockish idle, highest power possible, depends. you tube, ls1tech.com both have good numbers from LS1's with cam swaps. Check with the site vendors for a cam, or ebay. Ls1 cam in search. The valve springs usually depend on the cam. But patriot performance has prc duals good to .650 lift with guides, titanium retainers, locks ect for $255. Good for just about any cam that will fit without PTV clearance.Quote:

known performers of the LS1 are cams like the ''MS3'' ''MS4'' ''TRex'' ect. I personally like the MS3. Sounds nice, and proven to make over 400whp with boltons.
There is a nice used cam for sale here on this site. As well as Ls1tech, and Performancetrucks.net, and eBay Motors - Autos, Used Cars, Motorcycles, Boats, Trucks, Parts, Accessories, RVs and Other Vehicles has some nice nice deals.
I want something with a very close to stock idle. Would that require something with a 114lsa. I saw a video with a LS1 with a 228r I think but can't tell how close to idle it sounds like. So is the 25k stall sufficient?
So.....what are your goals or plans?
I was planning 420-440 on the rear wheels with the supercharger. What can be expected out of an LS1 supercharged?
at least that much. A good blower cam with a stockish idle is the GT2-3.Quote:

I'll just move to a 3k then, i found the cam and springs on a website for 480 bucks, should i change my pushrods as well?
Always a good idea to change pushrods that have been in a motor for a while, Especially since you are going with a bigger cam. Better to eliminate variables now that could possibly cause you greef down the road. But on the other hand if they are fairly new, still in good condition, and the right length then it shouldn't be a prob.Quote:

Any thought on the GT7 cam. I found it on a 01 corvette with the Maggie supercharger. It said it only put down 410 on the tires though. All it had was cam, Maggie and intake tube.
Hold on there guys.. Are we talking 241 heads? The stock ls1 was 10.25:1 compression wasn't it? I suppose some bowl work might get it down there enough for some boost.
Also your cam should be different for a boosted setup. Most guys run at least a 117 LSA, like a stock LS6 cam. The supercharger will push intake air through the open valve if you have any overlap, such as the cam you mentioned with 114. there is an overlap calculator around here somewhere...
And the cam will run great even if you never get around to the supercharger
Well the GT7 and GT2-3 are both meant for supercharged engines. Those are the usual ones that get put in the LS1 or LS-6. I have 3 cams that cam with the engine when I bought it. First the stock one, second a LS6 cam, and third a LS2 cam. I rather put in a new cam and get more HP though.
