511  Camaro Research Group Discussion / Mild Modifications / Late model master cylinder that will fit 69? on: June 12, 2007, 01:51:46 PM
I am looking for a late model master cylinder that will fit a 69 brake booster.  The flange needs to be approximately 3.40" center hole to center hole to fit my booster.  I am looking for the aluminum body with a plastic resivoir for a late model look and will function properly.  I was looking at Wilwoods 260-4894 and like the looks.  However, the flange holes are only 3.20" and will not fit.  I want a more late model look...what do you guys recommend that will fit?

I am wondering if my problem is just that I flooded/fouled/burned up a set of plugs and all I have to do is install a new set of plugs.  Is this possible.  I will try this next but I would hate to put in a new set of plugs and foul them up as well at a cost of about $4 ea.  Also, the spark plugs have writing on them saying "AC Delco" and "4" underneath that.  How do I find out what plug this is or will the parts store know if I bring them the plug.

I compression tested all of the cylinders and got a consistent 190 psi from all eight of them.  So I am guessing that the head gaskets and heads are okay.  So what do I try next?

Pulled the carb apart and the power valves are okay...so that is not the problem.  I cleaned the plugs but they foul in minutes.  I put the #1 cylinder at TDC and the rotor points exactly to #1, so I do not think the timing has jumped.  During initial first startups, the motor got hot as I did not have the radiator full with coolant and water.  I don't have the temp gauge installed yet and don't know if it just seemed really hot because I was working on it at the time or if I got it too hot and blew a head gasket.  Could these symptoms be caused by a blown gasket?  I want to check the compression in the cylinders...what would be the correct pressure? 


If you have any ideas that have not been mintioned, let me know as I will test anything to see what the problem is. 

As always, thanks for the help.

Also, how could a distributor be out a tooth or two.  I find that it can only be exactly right or 180 degrees out.  Sure the teeth will let you skip one at a time, but there is a "bar" or whatever that allows the distribtor to only fully seat in these two positions and will not lock down all of the way if you are only a tooth or so out.  Any opinions?

I installed a holley 803bp regulator and a return line and it did seem to help quiet my complaining electric pump a little, but not much.  Fortunately, the exhaust is louder so you can now only hear it upon initial turning the key startup.

Here is the latest.  Brand new ZZ502 with brand new Holley 850 cfm Model 4150 (part # 12366996) that supposedly has blow out protection on the power valve.  While trying to time the engine, I had one very loud back fire followed by a couple of minor ones.  The wax in my ears fell out on the first BANG.  The engine ran horribly immediately and the plugs were badly fouled.  Finally, the engine would not even start and would just sputter and backfire.  I cleaned the plugs and put them back in and was able to get the engine to run again, though still rough.  As stated above, the power valve in the carb has the blow out protection.  How good is this protection.  Could the power valve still be messed up and need to be replaced?  How do I check the power valve to make sure this is the problem?  Finally, any other ideas on what could be wrong and what I should check or try to do?

Thanks guys,

Steve

I am not sure of the third gen seats, but I put a set of fourth gen in my 69 and the only mods I had to do was the rear outside brackets needed to be turned inward and the rear near the tranny hump needed to be drilled out.  They fit fine in the front and the height was decent.

It is a holley 850 dp.  What should I check to find out if the problem is the power valve?

521  Camaro Research Group Discussion / Mild Modifications / Timing is out on a new motor. on: May 29, 2007, 08:58:42 PM
I installed my new engine and it ran fine.  I have never removed the plug wires since new.  During trying to time the engine I had a huge backfire after.  Now I have to set the timing to where the vacuum cone hits the carb just to get it to start.  It still runs rough and backfires slightly.   The engine timing acts like the distributor still needs to move even closer toward the carb just to run right, but O can't move it any more as it is at its limit and hits the manifold.  This is a brand new crate motor.  I don't think I could jump the timing chain on a new 502 with no miles on it and only about 10 startups (no?).  It ran great before the backfire.  Anything I should check?  I am sure if I moved all of the wires over one on the distributor it will run fine again...but this they are now set at the factory plug ins and ran fine before.  Any ideas.

523  Camaro Research Group Discussion / General Discussion / Need Camaro Pics for the Homepage for June on: May 29, 2007, 08:06:15 AM
Hey guys,

I need you to send me pics of your cars for the homepage for the month of June.  Especially 67 and 68 (why am I always begging for these years?).  C'mon you 67-68 guys...I get more 69 pics, but your cars were produced twice as long.  So, send em in.  I need all years please.

Send them to:

sdkar@bellsouth.net

The first 67 and 68 I received gets to be on the home page for the entire month of June.  How cool would that be. 
524  Camaro Research Group Discussion / Mild Modifications / Re: Serpentine belt setup for a big block on: May 14, 2007, 01:38:24 PM
Okay, here is the solution I used.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&viewitem=&item=330111429548

I found the brackets all over the place at the local junkyard.  I got mine from a 90's blazer for $40 for the brackets, idlers pulley, other pulleys and tension pulley. (Bring a steering pulley puller).

Anyway, the setup installed quite easily and I have a very nice stock look to my 502.  The setup also fits nicely with just enough clearance for the dual spal fans and the be cool radiator. 

If anyone else if looking for an inexpensive serpentine setup for their BB, I do recommend this.

525  Camaro Research Group Discussion / Mild Modifications / What is the purpose of a fuel pump relay for an electric fuel pump? on: May 09, 2007, 02:33:57 PM
I installed my electric fuel pump and wired it directly.  It works fine.  Why do I need and what is the purpose of adding a fuel pump relay?
