ever growing. Motor mounts are broken. They were BRAND NEW when before I had them install the motor for me.... so I'll have to replace those. new injectors are in, so that will be interesting to see how it runs with those the old ones were GROSS.
I'm holding off on anything else till I actually get it running. because it seems that its going to cost me quite a bit more money just to get it running than I anticipated. But I think after it is running, new seats are in order, my stock ones suck and are worn out.

Got my engine 95% back together! Things I still need to do:
find/replace one of the bolts for the power steering pump.
Put the belt back on (waiting on bolt as it will be impossible to replace it once the belt is on)
Figure out where one large nut goes that I have left over.
Replace the throttle cable that I must have closed the hood on and snapped one of the times I was working.
I'll need to replace the engine mounts, but that is not critical for my current progress to see if this fixes all of the engine surging/racing/stalling issues I've had.

Double checked all of those, its a much larger nut than anything on the manifolds. Not quite sure what it goes to, I'll have to go over everything to figure it out.

Lately there been a rash of posts installing brown dog motor mounts. IDK y tho. Haven't researched them recently but I think they're poly so should last long but transmit a bit more vibration.

was just looking at brown dog, they have polly's for $10 more than the ones I posted, and rubber for $20 more. Not sure... I need to do something, but its all a lot of money.

If you go brown dogs go rubber...poly causes ALOT of vibration even at idle...
Although driving it felt like riding in a race car but as a dd I wouldn't go poly...
