1969 Chevy C20 396
New to forum. I recently bought a very clean 1969 Pickup. It is a two wheel drive and has a very clean body with no rust.
the timing seems to slip, seems to the retarded side, causing it to lose power. I'm looking to do some easy horsepower fixes for under 800.00. any one have suggestions to wake up this old 396, I know it has much more power than it is presently doing, it's kind of a dog. electronic ignition and carb work?, if so, what kind works best. I just use it as a daily driver and may tow once in a while with it. (small boat) It presently has a small holley carb on it. (i actually prefer the old quadra jets) (high school days) Also what kind of carbs go best on these? I had a 396 in high school and it was much more a power keg than this truck. anyone know some good mechanics in salt lake area? I will post pics. Last edited by phil2013; 03-26-2013 at 01:28 PM.

Re: 1969 Chevy C20 396
first welcome... Those are cool old trucks. The 396 that year was peppy to say the least.
second, what do yo mean the timing seems to slip? Is the distributor moving? Does it still use points?

Re: 1969 Chevy C20 396
yes, it has stock dist and has points. the bolt is tight on the dist but seems to slip? prev owner said it has an rv cam, but i can't confirm that
I was told this orig came with a 350 but they had a mechanic do a 396 conversion in the mid eighties, (have the receipt) from the prev owner. |

Re: 1969 Chevy C20 396
Welcome to the board from a fellow Utahn.
An HEI and a good rebuilt Quadrajet would help wake that motor up. |

I run a stock HEI; I think I got it from a 1978 Chevy or GMC truck. It works great. You'll need to upgrade your wires, and make sure you have 12 volts to the HEI; the stock distributor uses a resistor wire to get 6 volts. |

Re: 1969 Chevy C20 396
welcome to the forum from Texas...what everyone else has said is a good place to start, also if the dist. shaft is tight it could make the dist. slip around. make sure it spins free..

Re: 1969 Chevy C20 396
If the distributor slips, that could just be it has a wrong hold down on it or the bolt isn't really tight. it could be a few things. I'd mark the distributor positon, pull the hold down off and check bolt, hold down and block to make sure they are all like they should be.
I have also seen caps that have the notch smoothed or broken off still work. They don't lock onto the distributor like they should. Check that. With points when the rubbing block starts to wear, it does retard timing and increase dwell also. You may want to look at that when you pull the cap to look at the notch.

Re: 1969 Chevy C20 396
Stick a HEI in it some new plugs and some good wires and maybe a new Street Avenger Holley carb, maybe a good aluminum intake.

Re: 1969 Chevy C20 396
I'd check that timing, dwell, vacuum. Check the choke pull-off to make sure you are not running around on just the primaries, check for burned plug wires. BTW, welcome to the forum.

Re: 1969 Chevy C20 396
When you found your truck for sale was it parked right near Interstate 15 not to far South of Salt Lake City ?
