faultymechanics Alright, I will get my Dad to take some pictures of it next time. Also RPM wise the jeep was pushing 37s with 4.10 gear ratio. Now though I am bringing it down to 33s. Also this jeep will just be used for light trailing, beaches, camping and my DD (hence the tire downsize). ALso I haven't heard any knocks from it running for a while though I haven't used it enough to know for sure and the only detonation I know of, was when my dad flooded the cylinders trying to start it haha.

Gunner Take a couple of pictures of what you've got so we can determine what you have as a starting point. Duffer is right.Basics first then look for outside problems. You say it runs/starts good when it is warm outside. Big journal 327's were camaro/fullsize/truck motors in 69 and most were 2 bbl low compression.

At the risk of being narcissistic, you can never have too much power. But way more importantly is where that power is at, specifically, where the torque is. For the wheeling I do, I love having 200-300 ft lbs below 1000 rpm-the hell with top end hp. If properly camed, a 350 works extremely well in a Jeep.

JEEPDON You might also wany to make sure valves and heads are up to burning unleaded gasoline if out of a '69. I know most have been updated; but with something that old, one never knows. Also, some of these engines ran pretty high compression for the sheeit gas we have today. Could wind up with detonation/knock problems.

faultymechanics Yeah I have read various things on the 327 and the 69 corvette. It says that it was the 350 at the time but there was also a strike by the workers at the time and parts were outsourced and I have read in a few places that some shipped with the 327 still. I plan on checking the block number when I am home from school and with the jeep. Manual choke swap is probably my best bet.

duffer Not to pop the bubble, but the 327 was not offered in the 69 Corvette, only the 350 and 427. 1969 was the last year the 327 was used in any GM applications. Are you sure it is even a 327? Since both the late 327 and 350 blocks are the same, if you don't know the history of it, even the block casting numbers will be of little use to tell what is actually in it. Could be anything from a 302 to a 383.

That aside, I have never had any small block Chevy not start in cold weather and most will do that without a choke. I actually prefer a manual choke.

I think if this was my problem I would start with the ignition and make sure timing/points/spark/dist advance are on spec and then deal with the fuel system. problems with any of it can make for hard starting.

faultymechanics Yeah I am 99% sure that is what I have on there. And are there any kits you know of to stay away from. They are super cheap so I don't wanna put a piece of junk on something that starts my jeep.
03-17-2013 10:18 AM
Gunner That should be a quadrajet 4 bbl Carb you have there if it is a corvette motor. That is a mechanical choke that was operated by a heat source in the intake manifold. You can pretty easily get one of the cable type systems and convert the choke to a cable unit.

faultymechanics Do the electric to manual choke conversion kits work well? Is that something worth doing?
03-12-2013 05:23 PM
faultymechanics Yeah it doesn't have anything to pull for a choke so I assume it is automatic. This is my first carb'd vehicle if you couldn't tell. I believe I looked up the carb a while back and it said something about electric.
03-12-2013 02:43 PM
lynn What kind of choke does it have? If electric/automatic, it may not be working correctly.
I always preferred a manual choke for that reason.

faultymechanics Don't think the carb was rebuilt but the motor swap was recent and the jeep was rarely driven. And the PO said that he was always on top of maintenance and would take it to his shop and tell them to fix anything needed for the tune-up. Once it is on it runs perfectly. I think I can get numbers for last tune-up but my phone is dead right now.

I was just figuring that with an engine from so long ago that I would need to modernize the fuel sending or something? Could it just be the carb? He said it starts up easy in the summer, he never drove it in the winter.

Raiderfan001 When was the last time it was tuned up? Spark plugs, plug wires, fuel filter, etc. Has the carb ever been rebuilt?

Carb'd Chevy 327

Hey so my 85' CJ7 has a Chevy 327 out of a 69 Corvette and I was wondering if there was anything I could do besides a FI conversion to make it easier to start in the cold. Any suggestions would be great, I have no idea where to start.
