Cobra Front to rear weight balance
Ive seen people write on this forum about the f - r weight balance. It seems most SBF cars have a near 50/50 balance the norm being 48/52. What im interested in finding out about is how the balance would be for a iron FE / iron jag diff vs alum FE / iron jag diff and alum FE vs alum diff.
How does everyones car stack up on this weight distribution balance??? Thanks guys |
Not quite that simple-need more specifics. EG:
My iron block, ally head / waterpump /intake in ERA w / jag IRS is 48 / 52 w / half tank of gas. Measured with digital corner weighting scales. It's 47 / 53 with me in the seat. The 'whole FE is nose heavy' is myth believed by the small block guys. |
I'm similar to Chas -- iron FE block, aluminum heads, manifold, water pump, and flywheel. Here are my numbers both with me in and out of the car. Half tank of gas and small bag of tools in the trunk. Digital scales, of course....
Left Front 646 (703) Right Front 666 (667) Left Rear 663 (756) Right Rear 678 (725) Cross Weight 1328-50% (1319-50%) Left Weight Percentage 1309-49% (1456-51%) Rear Weight Percentage 1337-50% (1478-52%) Total Weight 2651 (2846) |
ERA Chas - Patrick , you both answered my question. Seems it is all myth...
Is the FE engine positioned further back towards the firewall ? |
I doubt it. Acton or Kirkham could answer better.
|
Chas and Patrick are right on point here. When the entire engine is mounted behind the front axle centerline and the engine DOESN'T weight that much more than than a windsor, then looking for a beak heavy boogy man is gonna be hard to do.
|
Of course, a lot would depend on the chassis and other options. An ERA will have a differant balance than an FFR with the exact same drive line. And how the chassis manages that weight is also important.
|
The biggest extremes I have seen is 47/53 to 52/48.
A lot of people with small blocks would like others to beleive it's much greater than that, but it's not. And there are many, many other factors that will affect handling beyond just the weight bias. |
Big Block guys forever trying to make the case that there is no weight/distribution difference between a FE and a Windsor. Absolutely laughable, you can't argue with physics. Spend some time around the road course guys who WIN and see what they are running lol.

my jbl f-r is 45/55.:cool: |
No, no, no... it's the small block guys constantly trying to justify, and explain away, their poor decision.
Yeah right, take it up with Bob Bondaurant or the Shelby guys. Bob was one of the 1st to state the 351 Windsor was a better balanced Cobra for racing, you don't think he knows what works? When Shelby put their spec racing Cobra out it was a 427 body with a 351 Windsor, like those guys don't know how to make a properly balanced race car? ---- |
If it's a 427 car, and it doesn't have an FE in it, then it could have a uranium enriched phase engine in there that takes you to the next dimension and it would still be wrong, wrong, wrong. And everybody except guys that put wrong engines in their cars will all be nodding in agreement with that statement.:cool:

Bernie, bail now. Here's where all the good information in your thread goes straight to hell...........

I have see SB cars with more weight percentage wise on the front than some BB cars. A lot depends on the car make, options and such. |
