Weight Reduction (who has the lightest engine)
This is a little different thread about weight reduction because I want to focus directly on the engine. What you have done to reduce weight to your C4 engine? I am sure most people have not weighed their engines but those of you who have been concerned about reducing pounds may have found something I have overlooked. If you have any ideas about reducing engine weight I would love to hear from you with your ideas, tips and tricks. 
Thanks,

He is not a forum member. He is the owner of Jensen Engine Tech in Nescopeck Pa.
His car is extreme. Carbon fiber body, tube chassis, and a 427 cube twin turbo small block making 2300 hp. Every time I look under the hood, I find something new. Even the back sides of the door handles are milled out on the bridgeport.

You need to talk to the guys that build sprint car engines. One shop in TX that has a CNC block lightening program is Wells Racing Engines
(www.wellsracing.com). Go to their web site and click on the "video" link and they have a video of their block lightening process.
Good luck,
Dan

I think his website is www.jensenenginetech.com,
but I will double check. Pretty sure he has a photo gallery on the site. I will check.
Edit: link is wrong, don't click it. I will find out the correct one.

i managed to get 13 lbs out of my original 86E engine block, mainly using an angle grinder and drill.....
i also cut 3-4 lbs out of the original TPI manifold base as well, before i switched to a miniram.
last time i weighed my car, it was down to 3,040 lbs, curb weight with a bout 1/4 tank of fuel. still had the A/C, and original 16X9.5 wheels on it...

Is your friend a forum member? Can you share any further details about things he has done to cut weight? You have my attention because I am trying to build a 2500 lb C4 and I have tweaked most of the car and now it engine weight reduction time. I have the basics done to the engine but I know there are people who have gone to the extreme...I need some extreme tips and tricks.
Thanks,
Sam

wow Trog, that is an amazing creation.
Doesn't say if they can do 1 pc. RMS.
They want a $4K deposit. Wonder what the balance would be
I wonder what is the lightest crank for us C4 vette dudes would be?
