a very nice story clem....  Smiley
Did you use the same broom handle that they used to hold up their hood?  Smiley

J/K..
if what I did had not worked they may have used the broom handle on me.

a few years ago i was at a stop over point for the interstate battery great race. those are the real old cars that do a road rally. there was a 29 chevy there with a noisy engine so i told the guys get me a broom handle and start the engine. i used the broom handle on each cylinder and the noise was coming from #1. so i told them shut off the engine and remove the spark plug and give me a rag. they restarted the engine while i held a rag over the spark plug hole and out came a piece of metal. put the spark plug back in and they were on their way to finish the race. i got a nice write up in the rallys magazine later that year.

Thanks guys.

I hear and odd sound but it does not sound like rocker chatter. It sounds more like an exhaust leak but I don't hear it through all the rpm ranges. This is why I was asking about adjusting the valves. I have tightened up the exhaust system to the manifolds and tightened up everything else around the exhaust system (air tubes) and the sound is still there. I will keep listening and poking around.

I don't think it is time to adjust the valves based on what ya'll have said. I am not sure what type of nuts are on the studs. The car has been driven 6000 miles since last adjustment.


use a wooden dowel or wooden broom handle on the rocker cover with the other end in you ear and listen for a different sound. same for the fuel pump. you can check the fuel pump by just removing the bolts,pull the pump away from the block and with the fuel in the carb the engine will keep running but the pump will not be working. my new 70 454 450HP chevelle had a knocking fuel pump the first couple of weeks i had it and that is how i found it.

the tighter lash will hurt your bottom end power and with a close ratio trans starting out from dead stop could be a PIA with a taller gear. 302 are not loaded with a excess amount of torque

the original spec for 346 cam was .025/.025 but GM changed it to .030/.030 because the FI corvette engine did not like the closer lash setting lowering the idle vacuum. I would not use the .025/.025 on your Z/28 unless you have a 4.10 rear gear or deeper.

i am most likely the only person on this site that owned a new 68 and new 69  Z/28 ...................

use "PAL" nuts on top of the stock ones as a lock nut. the concave area goes against the adjustment nut

"On the issues with Jerry" section of the Ebay report, check the 4th paragraph in which the distributor number is short one numeric. 
It is most likely a (1) ..  All else is sooo specific..  Mebbee a typo.?.?
he made a mistake on my Z/28 so why not on this one ??

Does anyone know which car this engine came from? http://tampa.craigslist.org/hil/cto/4052796554.html

i believe a 69 engine should have the VIN stamped on the block from the car it came from.

If you had a carb with holes drilled in it like that is there any way to repair it and bring it back to normal ?
I would take a scrap carb and cut and machine disks from the choke tower for a press in fit to the holes. if you ream the holes for a precision press fit and machine the disks on a lathe this would work.

came from the same dealership as my special paint Z/28.b http://cgi.ebay.com/ebaymotors/RARE-1968-CAMARO-Z28-TANGERINE-ORANGE-AND-STRIPE-DELETE-/281160200929?pt=US_Cars_Trucks&hash=item41767432e1#ht_1178wt_1096

Why not just buy a double pumper carb to start with?
I was doing that before holley came out with the four shooter. I have a letter here asking about the fuel volume problem I was having with the pump and they told me I was wasting my time. I ran this setup on AFBs for years before holley became the carb of choice for GM. AFB carbs were not a problem because they had a larger volume pump. they also had a perfect place for the second squirter in the secondary thermal vent. we won a lot of drag races till they caught on as on the holley I drilled the squirter discharge holes in the air cleaner stud boss that squirted into the secondary capped off with a air filter stud.   Cheesy

the thinking now days about headers is not equal length as it wideneds out the torque curve.  the new grand am corvette race cars even have unequal length fuel injection intake stacks for the same reason

I would think a wider torque curve would be desirable, no?
yes it is on a road course
