Nice work so far!

Edit: Wondered what was with the dust...until I looked at the date stamps. I'm not the only one who put his engine swap on hold for a couple of years!

Looks like the engine was sitting in the car w/o the decklid and exposed to the elements for a couple of years. The concern I would have would be the open PCV ports on both heads likely allowed water and dust/debris into the engine. When you power washed it, if you didn't plug those ports, then that process likely put more water into the engine as well.

I would suggest you pull the valve covers and oil pan to inspect and flush any contaminants before you try to start it up.

The debris around the oil filter housing also should also be carefully cleaned and the ports flushed. You don't want any debris left in the ports and go through the bearings.

Put an inline filler neck on the top connection and run it to the left coolant pipe.

Run the lower connection (thermostat) to the right coolant pipe.

Dropped the engine again because the guy that helped me didn't remove the cross bar on the cradle and blocked the oil filter and exhaust manifold so we took it back down and fixed it it's going back on this week

I would recommend the oil cooler the engine bay is quite packed with the N* and the oil temp gets pretty high ,especially in stop and go traffic. I would also use only Mobile one synthetic oil for the same reasons.

I just saw that and assumed you were going to be running a remote filter.

In order to incorporate a cooler, you'll need either the OTHER factory filter adapter that includes filter connections, or CHRFab's remote filter mount plate.
Also check out Pure Power oil filters... stainless steel mesh, reusable and high flow.

That's my method using the stock bracket. The guy in your pic fabbed a new upper alternator bracket. If you do that, you can use whatever alternator you want.

Going to weld up a cover for that hole in your strut tower?
You don't have to cut off that much of the body side dogbone mount

How much did you cut off the hinge box?

Looks like the left side of your engine is higher than the right side and that it is slightly twisted, left side closer to front of car.

Sounds "flat", I don't think it's running on all 8, good work getting to this point.

It could be a lot of things (stuck injector or 4, improper IAC placement or minimum idle air, improper MAF table, vacuum leaks, etc)

I would try to keep it running with the throttle (even if you have to run it at 2000 rpm) and let it get up to temp and remove any air from the fuel system. If you have an IR temp bun, it would be good to check the primaries to see if they all are coming up to temp or if you have some that are cooler than the rest. If you have a scanner or tuning package, it would be nice to hook it up and see what all the sensors are doing. Otherwise, you might want to run it a few times until is sets some codes that could help pinpoint the issue.

Are you saying that the regulator was adjusted too high?

It sounds like it's idling well in the video. What was the problem?

I've used a '95 Corvette fuel pump for years. You could also use a Walbro 255.
