VCCA Home Forums TECHNICAL - 1945 AND NEWER 1965-1970 Rear Lights wiring/wood for bed

Was wondering if anyone here could help me out i have a 65 chevy short c-10 fleetside and cant seem to figure out how to set the wood around the sides of the bed. also does anyone have a set of wiring schematics for the same truck i cant seem to find any without having to pay for them.

Thanks for the info. Was thinking of going to 12 volt not because I thought it was necessary as my other vintage tin is 6 volt and never any problem. Was thinking the 261 might have higher compression which would nessitate staying with 12 volt. In the back of my head was remembering that was part of the reason Chevy went to 12 volt in 55. They deemed 6 volt hardly adequate to fire the plug with the increased compression of the 265. But that's a different animal. I now remember the 261 was introduced in 54 which was still 6 volt anyway. So I guess I'll stay with the 6 volt and go with the 216 starter and flywheel. Was thinking the increased power(torque) of the 261 would make possible a rear end ration in the range of 2.90 to 3.20? But only a guess on my part. Maybe too underpowered? What kind of reduction in rpm would I expect with 3.55 compared to org 4.11? In a Chevy PU parts catalog I have they have new high speed ring/pinion. 3.55 ratio for 40-54 and 3.38 for 55-62. I guess the higher 3.38 isn't manufactured to even be able to be installed in the older rear housing because of the difference in the rears between the years. I have a 59 Chevy which, I believe, has 3.55 gears. Would it be possible to install the gears into the 46 rear and keep the orig torque tube?

If you have a passenger car it would be very easy to install the 3.55 Powew Glide torque tube and carrier. If you have a truck you would need the special ring gear and pinion now being made.
Going from 4.11 to 3.55 would be about a 15 percent reduction in engine speed. This reduces the engine RPM's at 60 MPH from 3100 to about 2600. Makes 65 MPH easy.
Any other late axles would require changing to an open drive shaft and a later transmission.
A 1959 car with a standard transmission would have a 3.55, a P.G a 3.36. The parts would not interchange.

Saw this on Chatter II before and is a nice thing to go to. If you know what rear end ratio you are using or want to use and you measure your tire diameter that you plan on using, this web site gives you the answer on their opening page as to rpm you are looking for.

KenK, May I ask why you started 2 more new topics for 46 engine swap (46 engine swap 2 and 46 engine swap 3) rather than replying to the original thread (46 engine swap) about a 46 engine swap?
This is not a good idea, You are not getting the replys together on one thread.
