motor relocation

[T-Bagger]

say if you move your motor back in your chasi how far back do you move it before you notice a difference does it make a noticable difference i was just wondering because i have to have a drive shaft made already and i have enough aluminum laying there to do the firewall it looks like i can go back at least 5" and still keep my dash have you guys done this and how did you like it thanks Don

Let's say you have a g-body with a 108 wheelbase and you move the engine back 5" then you will improve weight distribution by about 4.6% x 550lbs for eng/trans = 25.5lbs. You also have to take into account for the mass moment of inertia of teh whole vehicle when moving weight around. By moving that much mass that much closer to the CG you reduce it's affects my reducing it's "lever arm" about the CG. Let's say you accelerate at 1G and the stock location for the engine is about 48" ahead of the CG. Then the force the engine will induce will be 550*4 or 2200lb-ft about the CG impeding rise of the front end. Now move the engine and the force is reduced to 1971lb-ft. You decide if it is worth it for drag racing. For road racing it will help alot more since more mass will be closer to the CG and allow for quicker cornering as well as the added benefit of weight distribution.

your going to have to put your motor in the back seat if you think that little small block is going to lift the front end.

Great web site. I had to visit it several times for a class I was taking. Lots of reading!

you cannot go wrong, well you can but its always good to move as much weight back as you can.

Dont forget the little things like being able to access the tranney bolts etc. Also have to remember crank centerline and angle...

Jeezus this thread is months old and Im replying...what a maroon.

OK bored at work.
