New Form Minnesota

April 04, 2020, 10:22:21 PM by JoshK | Views: 17 | Comments: 1

Hi All

I picked up my first ever project a couple weeks go, 1983 Short Box. It has very minimal rust but needs some love. The guy I bought it from used to drag race it 10 or so years ago and has been driven very little since. It currently has a Big Block with a cam,heads,MSD ignition. Its backed by a TH400 and 12 bolt with a posi.

The garage is already starting to fill up with new parts, I can't wait to start tearing into it. The forum has already been a big help!

-Josh

i have an 86 k20 350.... i'm fairly new to these older engines.... the tube on the passenger valve cover that connects to the pcv breather inside the air box.... this tube very easily moves back and forth on the breather nipple. is this ok/normal or does it need to be tighter?? it won't come off on its own, it's just nowhere near airtight.... thanks

Ok, in the rush and excitement of taking out and putting in the new transmission, i did not draw or take any pictures of the emergency brake cable routing.

Are there any diagrams or maps available?

My 84 K10 could use better brakes..What should be done?

I have an 84 chevy k10 SCSB that could use better braking. I'v been using it as a daily driver for the last 6 years or so and have made a lot of changes and a few have made things a little better but still not what I think they should be.
Here is what I have:

84 K10 Born a 305 with power disc in front. I assume the booster and master are correct for what it came with factory.
Truck has a 4" lift and extended braided front brake lines have been added.
Front and rear axles are off an earlier truck. 73-76 I think. Front is a Dana44 with stock disc and I have replaced the pads and rotors and bled them.
The rear is a 12 bolt with new drum hardware. It seems adjusted good but I know I have to apply pretty good pedal to get the rears to do much.

Lastly The truck is equipped with a 5.3 vortec I installed from a 2006 chevy pickup and it is all stock and should provide plenty of vacuum. Wheels are MT Classic III's 16x10 with some cooper A/T 35" tires.

Do I have a bad combo in there or is there something a should change to improve things?

Vapor lock issues - maybe??

April 03, 2020, 04:01:44 PM by Chuck Step-a-side | Views: 901 | Comments: 7

I believe I'm having vapor lock issues. The truck idles and runs smoothly until about an 30 to 40 minutes of driving and then when coming to a stop it will idle rough to were it's almost ready to shut off. I will maintain my gas pedal at 700 rpm to keep from the engine shutting off . The 1984 Silverado truck originally had a 305 and now has a pre-80s Chevy 350 (no center bolt valve covers) with an edelbrock 1406 carburetor and mechanical fuel pump with 2 outlets. The truck has a steel vapor return line that runs across the radiator cross-member and ends on the drivers chassis. I think there was a charcoal canister that connect to the vapor line at one time, but now it is open line and there is nothing hooked up to it. I have no idea where the charcoal canister was mounted or how it is connected to the return line.

So - should I install a charcoal canister or a phenolic carburetor spacer to help prevent the vapor lock? I appreciate any help. Chuck
