i need to I.D. this distributor cap and find out what yr/make its for.... cuz the distributor cap on my car i believe is the wrong one.... btw... i just bought a 92 camaro with a mid 80s TPI vette engine... or so they say... how can i I.D. the engine... anyone know where the vin for the engine is? the valve covers have the bolts in the center instead of around it. ty

 

Looks like stock large cap HEI.

 

I believe the '85 TPIs still used the large cap distributors. Any 82-86(ish) LG4 would have that dist. as well. If I'm not mistaken, it's also the same cap used on any pre-ECM (81-older), HEI distributors.

You basically have two choices, a large cap with a coil in it, or a small one with seperate coil (86ish-up).

I could be easily wrong but, I think any of the 'vette TPI motors had alum heads and the EGR valve was not under the plenum either.

 

well thats a pic of the dist cap im looking for cuz the one i have is a cap with the coil to the side.... and the wires i have hanging around near the cap and coil are pink with black strip and white. my main problem is i have 12 volts going into the coil and the wire becomes hot when key is turned but i get no spark at the coil. it has a new cap, pick up coil, coil, and control module was tested 5 times and it passed, so im thinkin its the wrong coil/dist cap set up on my car

 

'80'S Vette engines have 3 letter code starting with Z

 

k, kool.... next step is to i.d. the engine, then check ECM...cuz im hoping the didnt rig it up with a diff harness.... kinda looks like it. they had the electric fan and a few other things in the loop of the ingition wire that goes to distributor lol

 

You'd have the wrong distributor then. The caps are not interchangeable between the the two styles of distributors.

 

well the thing is, is that this car used to be a v6 and they put in a v8, but i dont know if they ever had it running.... and the wires hooking up to that dist on that pic are 2 of the 3 wires i have just hanging around, but ima try to I.D. the engine tomorrow to have more insight and post some pics of what it all looks like

 

The wires look correct.

 

i found a stamp under right cylinder head and it read MOO and it had three numbers on the left side of the engine kinda near the crank pull that read 638. anyone have an idea of what i have?

 

The deck stamp is next-to-useless. The 638 on the side of the block means the complete casting number will be 14093638. It's a 1 piece RMS 350 block.
