    LA360 initial timing too high - are there different timing covers?

    Just to update... Installed the Comp 260H cam this weekend. I installed it straight up, and double checked with a small homemade degree wheel. Based on this homemade setup, CCL and open/close were about 2 degrees retarded. But I figured that could be well within the margin of error with my...

    LA360 initial timing too high - are there different timing covers?

    nm9 - Thanks, I'll trust your specs. I couldn't find this cam in Elgin catalog, but found it on a speed shops site. I did use a felpro gasket when I installed the heads. The pistons didn't seem to have much dish (I've seen worse), but this is my first SBM - so no real reference. Although they...

    LA360 initial timing too high - are there different timing covers?

    I pulled the cam. Its an Elgin E1223P. I found the specs online. I guess this was the guys idea of a "mild cam". Camshaft Model Or Series: Performance Year: 1964 - 2003 Make: Chrysler Engine: 273 - 360 Camshaft Type: Hydraulic Flat Tappet Intake Valve Lift: .441" Exhaust Valve Lift: .441"...

    LA360 initial timing too high - are there different timing covers?

    Thanks Cudafever - I replaced the timing gear, and it looked like a standard key, but I'll dbl check when I go to pull it. The set I removed was a single keyway, and the set I installed was a 3 keyway 0/+4/-4. I did install on 0.

    LA360 initial timing too high - are there different timing covers?

    New gauge, but I'll try to verify it in something. Not that high, 1200' or so. I don't think the engine is worn all that much. I've had it running for a while over several driveway idles - round the block trips. There was no noticeable oil burn or blow-by. Keep in mind that the lifters have...

    LA360 initial timing too high - are there different timing covers?

    Its not polarity. I'm using a pertronix ready to run disty. Only two wires, red/black and they are correct. I dbl checked rotor position, and at TDC the rotor is pointing at #1 (I had checked that early on, but a lots happened since then and needed to refresh my memory). Now for the good (or...

    Spudders when it's hot..

    I added one of the add-on shrouds for my fan since I didn't have the stock one (see pic). In the pic. its hard to see how close your wires are to the wiper motor, but mine are really close and while adjusting time had accidentally gouged one of the boots. This would cause an arc to the motor...

    LA360 initial timing too high - are there different timing covers?

    Thanks - but the excessive initial timing it wants has me stumped. The carb is a new eldy 600. I set it up by adjusting both screws to 1.5 turns; then adjusted each (turning both the same amount in 1/4 turn increments while also adjusting idle screw) until I got max vac. Then tweaked both...

    LA360 initial timing too high - are there different timing covers?

    It does have choke plates. The engine was fully warm and choke open when I was trying to adjust and got 19". At one point in this process, I did adjust the choke to be about 1/3 closed warm. If I recall, I could get the timing a bit lower with more choke but it was still popping out the pipes...

    LA360 initial timing too high - are there different timing covers?

    Thanks MN9 - I will get a compression reading and reading on where the disty is a TDC this evening. Thanks

    LA360 initial timing too high - are there different timing covers?

    Thanks AJ - For clarification I could not get the idle to stabilize at 750, in that range it would sputter and die. Idle smooths out around 900-950 range, but even there would die moved from Park to a gear. I dropped my compression gauge, so I don't trust it. I'll pick up another this evening...

    LA360 initial timing too high - are there different timing covers?

    Thanks for bearing with me... Yes, I assumed the ext had leaked down some. When I tried to measure lift, ext was in the low 0.360 range; while int kept reading around 0.430ish. If my vac gauge is accurate, it was pulling right around 19 at idle, with only about 0.5 fluctuation. Unfortunately...

    LA360 initial timing too high - are there different timing covers?

    I put a degree wheel on the balancer, and used a dial gauge to measure int/ext opening closing (keep in mind its not ran in a few days, so I'm sure the lifters are down some). But I did get something close to normal (although it looks like ext closes a bit late too me; However, I'll be the first...

    LA360 initial timing too high - are there different timing covers?

    AJ - I think you might be right. I pulled the timing cover, and the marks were in the correct position. You are also correct on ATDC//BTDC - I mis-remembered the marks. See pics. It would help if I knew the cam that was installed, but unfortunately I purchased this thing as is and the person I...

    LA360 initial timing too high - are there different timing covers?

    Thanks - The rotor was pointing almost straight forward - where my number 1 is wire is.

    Correction. After TDC, not before.

    LA360 initial timing too high - are there different timing covers?

    Hi AJ, correct it is an assumption. But what I didn't mention is that with the air in the cylinder - I rotated the engine and the leak almost stopped at around 40 degrees BTDC (engine was fighting me with pressure in it, so hard to be exactly sure where the leak stopped), so the valves are...

    LA360 initial timing too high - are there different timing covers?

    Thanks all, I think I've figured it out. It is a valve timing issue. The pic below is after using the piston, stop. The black marks in the red boxes are were it stopped on each direction. I didn't measure, but can see it is close enough for government work! Now that the mark was proven, I then...

    LA360 initial timing too high - are there different timing covers?

    Thanks for the replies. The original balance looked correct for a 360 (based on google searches), the after market one was a summit pro street - It has graduated marks up to 60, which I thought would help me figure things out - pics attached. The marks are on the driver's side. I do have a...

    LA360 initial timing too high - are there different timing covers?

    Hello all. I've lurked around here for a while (lots of great info that helped me on my 73 Scamp project - thanks), but I've not been able to find info on my current issue... Timing way to high. Background, 73 slant car that I transplanted a 78 360 into it. I bought the 360 used, but was "told"...
