I agree D_B that would be awesome, GM basically replaced it with the diesel engine. Some of the fleet mechanics on the net swear by this engine. It's not without it's problems but they are not major and fixes have been documented.

I find a little piece of sanity through my vette project, other than that I rely on Jesus.

That being said, I wanted something different that no one else has. Something modern that will make me smile when I do hit the gas. I know it's not for everyone but it pleases me and that is what counts. I love the fact that I can get in it and it cranks and drives away without stumbling before it warms up. I like the fact that it will get 14 to 17 MPG unlike the old BBC that get 6 to 10 MPG. The best thing about it is if I dont like it I can install it in a boat, generator, water pump truck or anything else that needs monster torque and drop a LS in the Vette.









So here's to the BBC 496

I hope you have a build thread for this, i have been wondering about using that engine but havent seen any threads about them.

That Vortec8100 is impressive. I'm a bit old school too. A 496 can be built for way less with a .060 over 454 and a 4.25 stroke, and bolt right in with no effort. No hassle with electronics, mounts, hoses, exhaust, or anything else. Do some fooling around with Desktop Dyno - the class idiot could build one and come up with 650+ horsepower. A bit of tweaking here and there and it's 750. The one I came up with was over 750HP with an 850 CFM carb. Swap the intake and carb to a 1150 CFM, and you can't stick an eyelash between the top of the HP curve and 800HP.
Add $2300 for an aftermarket block and jump right up to 540 or 565 inches.

For my 540 I purchased a GM bowtie sportsman block from a gm dealer in Kansas. IT is rated at 800 horsepower. It is the low-deck version of the 572. They can be had for a lil cheaper than a dart block. The only part of the block I had trouble with was the timing chain. A double chain will not fit on this unless the block is grinded down, and i did not want to do this so I just used a single GM unit. I was at first going to build a 509, but a lot of guys said just go ahead and build the 540 for it's outstanding torque. The motor is built, I just have to install the fuel system to feed it, stainless lines, fuel pump, regulator, hoses, etc. hook up the Accel gen 7 wiring and fire it up. Should be soon. I can't wait to hear this thing.

My curiosity was more because the the 8.1 was built using research from the LS engines(from what Ive heard) except in BB form.
