I bought a reman engine, switched it out, did the toothpick trick to get it close to in-time, but when we started it it immediately revs so high I have to cut the engine. We messed with the timing a little and can only get it to run wide open immediately or or runs extremely rough and sluggish. Is this only timing? Or could there be another issue? We feel pretty confident we got all the vacuum lines on correctly. Do I need to take it to the shop and have it hooked to a computer or what? Very frustrated right now.

If it is the model with a TPS check these wire connections. Sounds like it is not monitoring the throttle position correctly on startup. If it the carbureted model, could be a stuck throttle linkage at the carburator.

Your air intake manifold isn't properly seated against the head. It is leaking from there and allowing air to bypass the throttle valve inside the throttle body.

Can the manifold gasket be put on backwards? It had pins so it can't be upside down, but it seemed to fit either way.

It's not likely the gasket, more likely is the intake manifold was simply not positioned properly over the small positioning studs on the head. It's common, someone asks about this issue here at least a few times a month.

Do you have any tips on how to position it correctly? I think I made it even with the head, should it be a little lower?

That's simply a judgment call, I think you'll be able to see how to reposition it now that you know it is easy to get it mispositioned. No one seems to have a problem getting it positioned properly the second time once they know they have to take their time to get it right.

You guys are awesome. I love this forum. I loosened all the bolts, repositioned the intake, starting tightening them down, got to the bottom front, heard a pop, then the back popped, finished tightening all the bolts....fired right up!! Now the check engine light is on tho and idles rough when you first take off. Then it goes away and runs fine...kinda sounds like it's getting too much fuel at first.

Turned the "distributor" to 0 degrees (pointing to the firewall) and it runs perfect now. No sputtering.
