SupraGlue Posted February 14, 2002 Report Share Posted February 14, 2002 I was doing a Google search on some stuff and found this info on the big block Chevy. I had no idea... "The 2001 truck line includes a new 8.1 liter 496 cubic inch "8100" big block. The bore will remain at 4.250", but the stroke will be increased to 4.370". The firing order is also new 1-8-7-2-6-5-4-3 and features individual ignition coils mounted near the spark plugs, similar to the LS1 Gen. III smallblocks. CR is 9.1-1 and it uses Sequential Fuel Injection (SFI). All 8.1 liter BBC production motors come with an internally balanced crank, four bolt main caps and redesigned heads with equal length port runners. The 2001 model 8.1 liter BBC uses a roller hydraulic cam and makes 340HP @ 4200 rpm and 455 ft./lbs. @ 3200 rpm. You'll be able to get either an Allison 1000 5-speed auto trannie or a new ZF S6-650 six speed manual gearbox with this new big block. Both trannies are built for a maximum of 520 ft./lbs. of torque. The Marine versions of the 8.1 liter big block comes in two power levels, a 375hp/490 ft./lb. model or a 415hp/490 ft./lb model." I believe that I am going to need one of those at some point in the future. Quote Link to comment Share on other sites More sharing options...
Guest stevil Posted February 16, 2002 Report Share Posted February 16, 2002 WTF?! I never heard of that... I wonder wow big those are? Hmmmmm. smile.gif I'd expect more power out of a 496 though, whats up with that? 496 LS1 would be nice. Quote Link to comment Share on other sites More sharing options...
SupraGlue Posted February 16, 2002 Author Report Share Posted February 16, 2002 Look at the compression ratio - 9.1:1 and the peak torque 455 ftlb. It's obviously set up for low-end pulling more than peak horsepower. I'll bet it's a great motor to build, though. Quote Link to comment Share on other sites More sharing options...
tandm Posted February 16, 2002 Report Share Posted February 16, 2002 that's ummm big Quote Link to comment Share on other sites More sharing options...
Guest stevil Posted February 17, 2002 Report Share Posted February 17, 2002 Yeah, I saw the torque. smile.gif I guess I meant thats what I want, my expectations of a 496. Quote Link to comment Share on other sites More sharing options...

Trouble Maker Posted February 17, 2002 Report Share Posted February 17, 2002 My uncle's f-250 has a fuel injected 460, he just got it rebuilt (lots of miles) .060 over. That thing, even before, can pull ANYTHING. It has so much torque it is unbelieveable, 3000lbs in the back, no problem, 6000 on the tralier, no problem. By no problem I mean you barely even feel it in the truck, he does have quite a bit done to the suspension too for towing. He says he wants another old f-100 some time, he used to have an old one before he got this, and wants to biuld that engine for hp and make a race truck out of it. I hope he does it.

Guest Blown4HerPleasure Posted February 18, 2002 Report Share Posted February 18, 2002 the horse power is low becouse we have a thing called emissions. Quote Link to comment Share on other sites More sharing options...

SupraGlue Posted February 25, 2002 Author Report Share Posted February 25, 2002 <BLOCKQUOTE>quote:</font><HR>Originally posted by Vette80: torque is what really matters anyway<HR></BLOCKQUOTE> For pulling dead stumps out of the ground, perhaps, but not when it comes to accelerating a mass. Area underneath the power curve over the given RPM range utilized by the gearing is what moves a car. Try shifting just after your peak torque on a run, then try shifting after your peak horsepower on a run, and then compare timeslips. I'll make a gentlemen's bet with anyone who would like as to the outcome. Quote Link to comment Share on other sites More sharing options...
Guest WS6Dave Posted March 10, 2002 Report Share Posted March 10, 2002 Hmm... think I could cram a 496 under my hood?.... Quote Link to comment Share on other sites More sharing options...

Anything is possible with the right ammount of money and patience. I think it would be much cooler and cheaper to just turbo the engine you have in there right now. That would be a site to see though, a v-10 out of a viper might be more fesiable, abliet more expensive, but even cooler. Quote Link to comment Share on other sites More sharing options...
