Now thats funny!!! Honey it was only cough..... I feel you.

You would be amazed at the cams you can run with these motors and still have better driviblity than the SBC. I ran a 232/242 113 and the car idled great and just ripped my vette to high 10s in the 1/4mile!My motor puts down 450rwhp I'm looking at getting a new cam made for the L92 heads looking for 500rwhp N/A with the same motor with my 240z.

Having had all gens of the chevy small blocks I would only consider buying and building Gen III/IV motors. Sbc and LT1 would not even cross my mind. I have put many cars together and worked with all the small blocks. I would have to say LSx motors are by far better than any sbc and LT1. They are easy to work on superior designed and just all around a better motor. My dad just pulled out his afr headed sbc in his 240z to put my 2004 LS6 in it. I'm currently going to be putting a LS2 in my 240z. My LS2 cam out of my 2004 Z06 and it made 450 rwhp and drove great. You just cant beat the tuning with bigger cams in the LS motors they drive great and make awesome power even with large cams.

Let me just throw one more thing out there. the tr6060 is basically just a newer version of the t56 built with a lil more beef from the factory but as with the older ls motors you can build a built proof t56 for a decent price. I abused the hell out of my last t56 450 rwhp and lots of drag racing it held its own. Seriously check out ls1tech you can find similar deals from their sponsers too. Anyhow good luck with your build.

Yeah a boosted ls motor in a 2400 car will be fun. My motor makes 450 rwhp right N/A. Comp cams just released 27 new lsr cams. I'm looking to make 500 Rwhp and 470tq with one of those new cams. Any how I will watch this build. In the future I want to slap a Magnacharger tvs 2300 on top of my motor I would like 650 rwhp lol. http://www.ls1tech.com/forums/generation-iii-internal-engine/1017087-comp-cams-new-lsr-series-cams-27-new-grinds.html

No prob anytime. ls1tech is a great source for info and parts. Yeah the rod bolts are just cheap insurance for your boosted stock motor. Another head to look for is one gm is soon to be releasing. I'm not sure what they will be calling them. I have the larger bore versions my self they are called L92/LS3 heads. mine are L92 and I have the matching L76 intake which came from gm parts dealer for like $550 and intake included fuel rail 39# injectors and 90mm throttle body! I believe the L92 heads were under $200 a piece bare too! any how look for the small bore l92 heads soon they have similar size chamber as the 317s but flow like a set of cnc'd head right out of the box.

Also before taking the plunge look at some the gm sites I have been on ls1tech.com for a long time there is like 130,000 members there. Lots of stuff on there to check out. Personally I would look at a motor built by a speed shop and look a wrecked car to get the trans acessory and pcm from. ♥♥♥♥ for $10k you could get alot. If interested I can pm you some sites but you can get an ls3 stroked to a 418-427 for $7400. the other $3000 you save you could get everything else. I personally have a whole bunch of LSx parts I have aquired over the years. I'm going to be running a 2005 forged LS2 with 2007 LS3/L92 heads and intake. I'm gonna use 2001 fbody acessories 2000 fbody wire harness and 2002 pcm, oh yeah a 2002 fbody t56 transmission.

That price seems high to me. But on the other hand you dont have to piece anything together. My dad had fbody(camaro) acessories in his 240z. I think I have seen corvette acessories on some too. The difference between the vette and fbody is the placement of power steering pump and alternator as well as the crank pully. The vette pully is just a little shorter and inturn the acessories are a little closer to the block. The vette alternator is up high on the driverside and the power steering pump is lower. the fbody alternator is low on the driverside and powersteering is up on the driver head. The reluctor ring dosent matter as long as you have the computer to match it. Personally I think the 24x ring is more popular right now, but the 58x computers are far move advanced and can be tuned really cool with say a 6speed automatic. most 2005 up gm stuff is 58x fyi I believe I posted in here the other day explaining it a lil. Good luck with your project!

What heads are you using with your set up?

Well I've been around LSx motors since the begining so let me chime in. Outward appearance of the LS family of motor as well as exhaust flanges are all similar and accesories are usually interchangible. Kinda like the Gen 1 chevy small blocks from 50s to early 90s. So for example you can put a 4.8l truck motor in your z or a bored and stroked 440ci ls7 they fit the same! Now interenals can vary on the LSx motors. You need to run a computer if you are keeping efi that goes along with that style motor. Example 2004 and earlier LSx motor have a 24x reluctor ring on the crank. this ring is what is used by the pcm to know where the cranks current position is. Some 2005 all 2006 and up factory motors have a 58x reluctor ring on the crank. Now rings can be bought and changed at a machine shop so just beaware of what you have. An LS3 unless bought from some of the sponsers of say LS1Tech or some other modern gm sites will have the 58x reluctor so Plan accordenly. Just to put it out there while I'm rambling. 2005 GTO LS2 have 24x ring while 2005 corvette LS2 have a 58x ring. Truck motors I believe went to 58x in 2005 as well. Anyhow I hope that helped a lil bit.
