His comment about "the hit" and too violent of a hit is the clue.
With some of the new converters that have a hard STR rate I see the same TOO MUCH HIT. Especially on some lighter cars.

The nice thing on our Plus Sized Cars is that we have real 4-link suspension.
The weakness are the attach points on the Frame.

For some reason when properly stripped they can get fairly light even with BB.

Will what was the lightest weight you got your car?

Dan

for some reason i remember 65-70 fullsize chevies having a 3 link (2 on the bottom,1 on top) on the base models with small blocks....or am i just dreaming?
seems to me the 4 links were the higher HP models...

Tom , most (if not all ) of the 12 bolt cars had the 4 arm suspension.
Most of the 10 bolts did not, although I have seen some 10 bolt 4 arms.
The holes are all there in the upper cross member, so the 4 arms bolt right in...

Hey Joe, good hearing from you. Yes, Carl is taking pictures and video. I will be posting a new pic next week of the rear frame gusseting work. Only way to make these boats survive!

Rob has the motor in South Carolina with the 1976 Ford F100 truck i bought down there. He has been using the truck w/ the new house. Don't know if I can use it as a tow vehicle, being a Ford and all!! LOL

Dan, the lightest I had the 68 was a the minimum H/S weight or 3950. I added a 135 pound bar to the back to make I/S ! If you want i can e-mail you a pic of the rear work I did on the car so you can show your chassis man.

That was the X - Frame 1958 - 1964 Chevy/BOP/Caddy
Yes the 58 got the X-frame as GM began installing heavier engines.
GM always boosted about the ride quality.
The Lower Links were angled toward the X-Frame and no Panhard Bar.
This frame required 2 - short drive shafts and a Center Link prone to snapping. (I know that so well)

65 - 76 went to H - Frame 4 Link set up with Panhard Bar.
Spring set on the Lower Suspension Link.
Used much heavier U-joints.

Then 77 up to 96 D / B Body used the earlier 1964 & up Chevelle/BOP Mid sized car H-Frame set up.
Upper Control Arms were angled eliminating the Panhard Bar.
Spring mounted on the Axle.

The 91-96 used a 8.5inch 10bolt that has a history of being very rugged.
Someone said you can put a larger 8.75 12 bolt Carrier in it.
Never understood why they were not put in Camaro/FB?
The Drive shaft rarely had any issues.
U-Joints lasted the life of the car regardless of abuse.
For racing gears just needed a balancing and the weight tab removed from the Yoke...and still keeping the original U-joints.

On my 1995 Impala SS purchased a Dick Miller Frame Connector for the upper and lower control arms.
Think he makes it for the Plus Sized cars too.

Hope this helps..

For the record:

65-70 full size ..3 or 4 arm (right or both uppers). Panhard bar, and springs on trailing arms.
71-76 ..Std 4 trailing arm, springs on housing , except for f/s wagons ,which were leaf springs.
77-96 Std 4 trailing arms ....7.5 rear standard in these cars... even in f/s Chevy wagons.

91-96 all got the 8.5 inch Rear, at least the 5.7 liter.
Have them on both my 94 Caprice Wagon an 95 Impala SS

The Camaro/FB got the little ones

Nope....you didn't say 5.7 cars, which may be true.
305's came with 7.5's ...I had one...with a 2.56
That gives you about a 1.80 gear in OD..That's how it got 28 mpg @70 with the a/c on.
