Re: Rod Bearings ???

Did the rest of the upper bearings still fit snug in the rods? When I spun a rod bearing due to detonation most of the upper rod bearings got hammered and lost their "crush". They basically fell out of the rod during disassembly.

Here is the Hillbilly way to check the plug wires for 'leaks'. Wait untill the sun goes down...raise the hood...put a little heat in the engine...Put the engine on the trans. or foot brake and see if you have 'light show'.

It is my opinion that your combination has more ign. timing than it wants. Could be that the timing being locked is making it worse.

What do you have for a spark plug?

Not only the hillbilly but also the redneck way too check plug wires or just grab them 1 by 1 and run your hand up and down them if it bites you you want to do the after dark test.

Those with pacemakers may want to opt for the "light show" method. Shocked

I got lit up by a 6al one time. I don't even want too think about a 7. Shocked

aint just the 7, its the pro power coil. Blaster coil is about 18,000 volts, pro power 48,000

So I will try and talk the new guy a work into coming over and checking my wires while she is running Laughing

The first two motors (DOVE heads) had autolite 45, last motor had autolite 25

Was looking at the third motor crank last night the bearing was hammering at BDC

Lem Evans August 8th 2013, 10:04 am

I'm not sure what a 25 is but, the 45 are too hot for the application i.m.o.

AR33 or AR32 would be better.

HELI-ARC August 8th 2013, 11:19 am

Ok I will use those next time. Do you have any theories on why its getting hit at BDC? Thats not Making sence to me as a timing or plug issue.

zrob90sc August 8th 2013, 11:30 am

Autolite 25 is a hot plug. They are recommended for stock low compression 2v clevelands. Pics of the bearings and crank would help solve the issue.

Is there a cool way to test for this? As I would like to sort this out on the next build. Just a note when the third motor was running at an idle I did check all the plug boots on the pass side and up the wires bare handed trying to find my intermittent miss and did not get shocked any where. Also like every other motor out there the wires are just draped over the valve cover (trick flow tall cast alum).
Thanks for the input to date

msd makes a in the car tester to test the msd box or distributor.i have seen the tester used to find a problem with an ignition turned out to be a pick up coil in the distributor.in his case the misfire would only show up now and then.
