ok yes i have sprayed it 5 or 6 times
i am fairly positive it is not a carb issue because it began with the 650 i had and got worse with the other, i also put a buddies 750 on it tht i know works with no luck, it IS oil on the plugs, if it looks like oil, and smells like oil it must be oil
i was recently told tht when i built this motor i did a big no no and reused the seals because i used the same headsafter they had been vatted
this is why i am leanin toward them as the prollem and because the plugs have fouled out 3 times in 1000 miles, the oil is all the way up on the threads of the plugs not just the tips
there are only two ways to get oil on the plugs right? rings or valve seals
i do not have a vaccume guage but it would do no good due to the fact tht it will not idle or run
and ya mopar lol ive had to change those a time or too jk :P

if you are getting enough oil down valve stems to foul the plugs then the guides are worn out bad.,,as I stated earlier , i have run heads with NO seals at all with no problems ( good tight guides) just my input

heres a thought i know my cam is way to big my carb way to small and my preformer intake to restrictive for my heads (ported and polished) and my car idles like crap when it does made small adjustments to carb and got it as best as i can. (found out recently the parts arent meshing) so my thoughts on this are that one ore more parts not meeting the requirements you need. and the 750 you borrowed may not be adjusted to your engines need hence the problem still there

How much nitrous are you spraying :?: And how much timing were you using :?: I just got a feeling this might be the root cause, When i ran nitrous i was tempted to use it when i shouldn't :!: :!: When you used it, did the engine make any noise at all :?:

After reading thru the carnage once more, I'm starting to think you may have toasted the rings and or pistons with the "squeeze" there BOWHAY.
It's not hard to do, add a little too much nitrous, not enough fuel, too much timing, and wham-bam thank you mamme>>>Smoked another SBC!!
Again, Just my 2 cents...

First time weighing in on this thread, i can say if it's oil, the rings or the guides have gone south. I don't run seals an any of my racing engines, but they are on alcohol, on my street engines i only run ford bonnets on the intakes. I donot run more than .002 clearances on the guides, any more than that i knurl them or replace them.
