Stingray V12 build....

[Richard454]

I've been working on this swap/rebuild/restoration a little over a year and ½....

Matt AKA DB- graciously asked me to bring the build over here- where I might get a little more appreciation or rather a perceptive recognition of the quality in the build rather than how sacrilegious it is...Heaven forbid an European Engine in a Corvette...Personally I think Duntov would dig it -
“Zora Arkus-Duntov was born in Belgium, raised in Leningrad, and educated in Berlin.
He brought his European automotive high-performance experience to bear on the just-introduced Corvette”

Here's what I'm placing between the frame rails...



A BMW V12 circa mid nineties- it's an all aluminum 60 degree with 322HP stock NET....10:1 compression-roller single overhead cam which weighs in around 500lbs.
Dimensionally it's about the same size as the LS5 that was originally in my car...but the "numbers matching" motor was long gone when I bought it in 1980....

I'm not going to have to mod the body or frame- but I'm having to dry sump it for front crossmember clearance.

Here's the mounts- using the stock chevy motor mounts


Here's the custom oil pan-

How it started life-

[Richard454]

Heres's the serp belt set up- using stock BMW pulleys and Denso Mini 75amp alternator- and a custom machined adapter to spin the Peterson 3 stage pump






It'll be backed up by a Richmond Overdrive 6 speed- custom bellhousing utilizing a BMW E31 (AKA 850CI ) flywheel drilled and pinned to fit a Chevy 10.4" clutch.

The suspension- Vansteel full coilovers front and rear ( w/ offset trailing arms) and Boss 338 18 X 8 front and 18 x9.5 out back

I can dig it.

Richard, thanks for posting. I'm totally digging the project from start to finish and I can't wait to see more.

I agree, as will many others, this is an awesome project.

There will always be someone who doesn't agree with what you're doing but I just hope they can keep everything positive and try to respect all the hard work and imagination that goes into this project.

No room for a Negative Nancy in this thread.

That's the "Reader Digest " version....

I've used a couple of the older V12's as mock up- I just purchased a 1996 low mile BMW 750IL parts car- and this is the motor that's going in it-





Comments -good or bad- WELCOME!!!

Matt-

If you need dimensions on the mounts- not problem at all sharing...AND if you're really looking for a V12- I have a line on a great deal- but you'd have to pick it up in PA... less than 4 digits- REALLLY!!!

Looks like a very ambitious but well-thought-out project. I wish you much luck with the endeavor. It will be worth it just to hear the exhaust note.

Just curious as to the weight of the BMW V-12 powertrian versus the stock Chevy 350?

A bare SBC iron block is around 180 lbs. Fully assembled with iron heads and iron intake it's nearing 575 lbs.

A fully dressed BMW V12 is a hair over 600 lbs. Now, knowing that Richard has killed a few of the accessories he may have dropped his V12 down to SBC weight.

I dig it

I love people who can do this kind of thing.
I would end up with two junk cars.

Great build! Keep the pictures coming. That is going to be a sweet and unique ride when you are done. The suspension looks great too, btw.

Thanks for sharing with us. I like upgrading a c3, Chevy dropped the ball in the 70 s with barely enough power to get the Vette moving. This will be a interesting build and one to follow. A lot of people tell me I shouldn't put a 8.1L in my Vette because it is a truck engine, but I just smile and think about all that torque it produces. I've been thinking about naming my Vette torque monster, you'll have to come up with a name that fits the v12 thanks again Mark

Nope....The FULLY dressed 5.4l (328ci) V12 weighs in at 529lbs- including AC, PS and a big ass 140amp alt...Mine in it's current state will be right around 500lbs.

Read somewhere of an actual weighing- but BMW rates it at (the older V12 circa 1988-296HP) at 1.77lb/Hp- or 523lbs....

It's really light - where as the crank doesn't have a lot of counterweight due to it firing every 60 degress and the vee is 60 degress- It's really smooth....

Coin balance...
