good tune up parts for a 327

[Keith B.]

for my dads 67 original 327/300 vert tried to get it out for the first time this year. but we had a lot of problems so fair. tried to start it and here the battery was died. so gave it a hot shot. tried to start but had no fuel. looked over everything here the inlet fuel line to the pump was pinched shut. fixed that. gave it another hot shot got it to start but it ran very poorly. would not idle correctly etc. so we are thinking its time for a major tune up. whats on there now does not look so high quality. in the past we always bought AcDeclo parts. is that still a good idea. last year when we put it away it ran fine and like a top. and for the battery we did have a battery tender on it but it appears the cut off switch that we put on failed somehow.

You need to do more diagnostics beginning with a thorough visual inspection of all the ignition system components. Then put a dwell meter and timing light on it to check dwell and initial timing and proper functioning of the VAC. Inspect and check all the secondary components - cap, rotor, and wires including their resistance not to exceed 5K ohms per foot.

BTW, when the the last time the distributor was disassembled, cleaned, lubricated, and inspected for proper assembly clearances and operation?

If the ignition system checks out okay, your problems are probably with the POS Holley - the worst OE carburetor ever installed on a Corvette engine.

All "tune-up" parts including those marketed by Delco are made by Standard Motor Products including Echlin, Neihoff, BWD, Standard (and their Blue Streak brand) and most of the other traditional replacement brands.

But beware, there are parts made by no-name overseas manufacturers that are not as good as the basic SMP line, so buy any traditional name brand and you should be okay.

Delco is just a marketing organization. They don't manufacture these parts any more - just buy them from SMP and put them in "Delco" boxes.

Duke I could not begin to say if and when the distributor was ever rebuilt or checked over. dad bought this car 4 years ago. we know the engine was rebuilt over 15 years ago.

Re: good tune up parts for a 327

I'd bet that the thing has never been disassembled. The dist. is one of the most overlooked components on the engine, yet its operation is critical to proper engine performance.

It's an easy job - procedure is in the '63 Corvette Shop Manual and later COMs.

It's also been discussed here many times in the last 10 years.

As Duke says, I think the SMP-manufactured parts will be fine, regardless of which branded product you choose. Personally, in this day-and-age, though, I like the ignition parts available from Accel. They're more expensive, but I think they offer a better product. This includes points, rotor, and cap.

thanks for the help we will look at it more tomorrow and see what we can do. having 3 old cars in the house makes every weekend full of things to do

Think you guys are missing the point here. He said last year it ran like a top.
First thing I would look into is bad fuel. Bill.

Re: good tune up parts for a 327

I wondered why a fuel line would get "pinched shut" in storage, but decided to let that go.

As far as distributors go, I bet about 90 percent of the cars owned by NCRS members have distributors that are in need of a thorough overhaul.

It's very common to find sticky centrifugal advance mechanisms and dead VACs. Also, the upper bushing is lubricated by a small grease well, and most find that this grease well is long dry, and once the grease dries out upper bushing wear accelerates.

Overhauling the dist. is easy as long as the bushings are okay. If they need to be replaced, most should sent the housing out to a specialist with experience as the bore should usually be align honed after bushing replacement.

Keith, I assume that you are talking about the blue '67 with the original paint. Is it going to be a driver or correctly restored ? PT

I would go with a good tune up an good parts.

But the first thing I also thought of was the fuel dried up in the carb and left a gummy residue.

Duke

the reason why is it has the common service replacement pump that has the inlet line pointing the wrong way. we did a quick bubba fix by putting a spring in the fuel line until we get the correct pump.

Joe you wouldn't know the Accel part number for their point/condensor kit with the high tension points spring by chance. 67' 327-350hp

The local FLAPS here are clueless, one place didn't even know what ignition points were.

Don -

The 28-32 oz. tension Accel points are their #8104.
