yes
A 1974 Chevy Impala frame would work
Check with your local Chevy dealer on that.
no
I would guess about six quarts...
The online website 'Car Parts Discount' is one place where one can purchase authentic Chevy Impala parts. Another site to check out would be GM Parts Direct. One could also search Impala parts.
Chevy already put the 5.3 Liter V8 in the Impala in 2006. It makes 303 H.P. Putting a 5.7 could be done, but the expense would be great. I would just look for a factory V8.
ON the 2006 impala that whining noise is actually the electronics when you accelerate. Its more or less electronic pulses/signals My 06 Impala is the same.
Weight of the vehicle
Could be Warped Rotors. Have them checked.....
No, this would not be a direct bolt in.
Which one would I get good as miles and would be comfortable for me nd my wife. We are ages 66 and 64?
It would depend on the size of the suit cases.
