Had a good time at the races with friends. Chased some gremlins but the car ran 10.30's calculated. Had to run the 1/8 due to a crosswind.
Put my "Pontiac" tools away and got my "Chevy" tools out. The Chevy tools are smaller and make less torque so you have to work harder.
Anyway, swapped the March underdrive pulleys from the 88 to the 85. Fortunately the front of the 4.3 is the same as the 350 so
the newer tensioner,idler and belt were swapped also.
I had it worked out that with 4.10 gears (up from 3.42) combined with the underdrive everything will be turning at the same rpm as stock
at any given speed. Well not everything, I got the AMP series so the alternator will be spinning at "4.10" speed.
Never put my meter on it but used the stock gauge for the following:
The gauge would read 1 notch above the 13, no load at speed, read on the 13 loaded at speed, 1 notch below 13 at idle, loaded.
Now the gauge reads 1 to 2 notches above the 13 no matter what. The battery will be happier and more importantly the cooling fan will have all
the power they need.
Also found the previous owner had spliced a CS 130 plug on the harness but the alternator is a CS 130D, "round hole , square peg", literally.
Dug up a CS 130D plug and crimped it on for now.
Last, adjusted the sway bar ends with the hot wrench to better match the mounts on the lower control arms. Hope to have it mounted
permanently tomorrow.
Can't happen soon enough, overloaded with camping gear, full gas tank she wallows a bit!
