Tim240z Posted April 1, 2005 Share Posted April 1, 2005 That is sweet, but I bet a second mortgage will be required!! Quote Link to comment Share on other sites More sharing options...
Griz Posted April 1, 2005 Share Posted April 1, 2005 GM parts has the part number, not the price. They say available in Fall 2005. Maybe only a second mortgage required. Quote Link to comment Share on other sites More sharing options...
qwik240z Posted April 1, 2005 Share Posted April 1, 2005 GM parts has the part number, not the price. They say available in Fall 2005. Maybe only a second mortgage required. My guess is around $12K Anybody else? Quote Link to comment Share on other sites More sharing options...
jsap Posted April 1, 2005 Share Posted April 1, 2005 I am guessing around arond 15~17K. Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted April 1, 2005 Share Posted April 1, 2005 There has been much speculation over what the price will be on the LS7 in crate format on some other forums I frequent. One individual (who works for GM) said that word around the office was that the price would be around the 15k range. It is one killer engine though! If you're looking for other exotic powerplant options... check these out... http://www.brammo.com/content.php?content.16 3.5L all aluminum V8 that weighs only 340 pounds. Dual exhaust ports, supercharged, very trick! 560hp at 8000rpm and 420 # torque at 5500rpm. They'll also slap a pair of turbos on it if you like! http://www.falconerengines.com/prod04.htm Then there is the Falconer V 12. 600 cubic inches, only weighs 500 pounds and makes 800 horses and 780 # torque on pump gas! Oh yeah! Or get the race gas version which puts out well over 1000 horses and gobs of torque naturally aspirated. If only I had the money.

boodlefoof Posted April 5, 2005 Share Posted April 5, 2005 grumpyvette, I wholeheartedly agree. And, I have that article burned into my memory... from the time I first read it in the magazine on the newsstand I thought it was an excellent buildup. I had always wished that they would revisit the engine and see just how it would do with more compression and a bigger cam. If it could run 11:1 on 87 octane and a short cam... I imagine 12:1 would be pretty simple. Or, think of forced induction... Quote Link to comment Share on other sites More sharing options...
Mikelly Posted April 5, 2005 Share Posted April 5, 2005 To further complicate the mix... While at VIR two weekends ago, I spoke with a source who shall not be identified, but was present the previous week when GM was at VIR WITH their new Z06 platform testing. The new LS7 has some issues with SLINGING the crank pulley OFF the front of the motor... STILL have not resolved the issues concerning that and GM is wringing hands over it! Might require a bit of "WAIT AND SEE" before they get my hard earned coin! Mike Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted April 5, 2005 Share Posted April 5, 2005 another book to throw into the mix... For those considering playing with turbos. I'd recommend "Maximum Boost" by Corky Bell. I also hear that Mr. Bell is coming out with a new updated version soon. Quote Link to comment Share on other sites More sharing options...

Michael Posted April 6, 2005 Share Posted April 6, 2005 Is the difference between LS6 and LS7 so enormous, that the latter justifies a > 100% price premium? Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted June 21, 2005 Share Posted June 21, 2005 Just wanted to update this thread... I've been told that Scoggin Dickey Chevrolet has released their price on the LS7 engine complete from intake to oil pan and including exhaust manifolds... $13k. Not sure if this includes the wiring harness or computer. Quote Link to comment Share on other sites More sharing options...

Might require a bit of "WAIT AND SEE" before they get my hard earned coin! Mike[/quote'] I think they torque to yield on the crank bolt similar to LT-1, this is a practice that was adopted for certain critical joints like pressure vessels which require insane flange loads to keep the flange from being the failure mode of a leak (this method was adopted empirically). But without torque verification, and if done by a grease monkey, it could have disastrous results. The trouble with this method is with higher strength bolts like ARP bolts at higher than grade 8 strength, is that they are brittle to begin with and when you torque to yield your yield strength is nearly equal to the tensile strength, but in a cast crank, or even a forged crank it's ok because the yielding is being done by the threads in the crank not the bolt. However, put a high strength alloy crank against it and the bolt may very well fail just a few ksi above what you've stressed it to using torque to yield. Then you add to the equation a damper that has a different (larger) coefficient of expansion than the bolt and it expands more rapidly than the steel bolt when heated and "pop". Newer thinking is to actually think about your torque spec and bolt choice instead of torqueing to yield, then things don't go "boom". Let me know if I'm off base here, but I think they should hire me. Quote Link to comment Share on other sites More sharing options...
Guest dancaprar Posted June 27, 2005 Share Posted June 27, 2005 i would hire you...but then again i tend to kiss *** when it comes to people who know A LOT more then me when it comes to automotive type things.....come to think of it THATS why my upper lip has been stinkn for so long.
