Bracket for accessory belt tensioner complete but rough, grinding and painting to come. Still the belt lines up very well.



That means that the belts are done, now on to wiring.

Rant: i now have 5 electrical things on Freya that need to be fixed. The headlight motors, the windshield wipers, the radiator fan, the tachometer, and the remote trunk lid release.

Cant seem to find fixes for these bugs. Very frustrating

Been a long time since i posted. My motor is now out of the car. Built a beam in the attic with a hook down thru the ceiling. Once the motor was unhooked from the rest of the car, it took a max of 15 minutes to slide the motor out the side. i expect i will have to put in in several times to check the measurements. My motor mounts are going to work just fine, i think. Gonna have to angle my angle to the cradle too. i spect that i will be able to measure and build a dogbone, and tack it in place to the alternator tensioner bracket.

i'm trying to mount my engine on the cradle for a test fit and my motor mounts are too far forward on the cradle.



When i braced the forward tranny mount, as often discussed, i put the bolts on the drivers side holes. Maybe i should have put the bolts on the passenger side holes as this would have shifted my motor rearward. Any thots?



Would moving the tranny bolts to the passenger side holes cause a problem?

No they are not too far forward, they are in the correct spot. i need to modify my motor mounts to fit.

Yep, now the engine is too far back in the compartment and i will have trouble with the exhaust. Plenty of room in front to clear the hinges. Gonna move the engine 3cm forward and mount the forward motor mount on top of the cradle.

Would moving the tranny bolts to the passenger side holes cause a problem?Yep, see above.

And some detail pics:



The SC roller with the ICM cut off.



The tensioner for the accessory belt, with the dogbone mount, tacked up till final fitting....



N the dogbone bracket in place - looks low, i could raise it up 1cm.



The coolant fill from a duke - this is the second iteration - the first one was too tall. i might have to modify this one as well.....

Well, that "catches me up" to today.



Fuel lines hooked up to filter and fuel rail. The fuel injectors have been cleaned, new filters and o rings installed, but one washer on bottom broke....



Throttle adaption. The pink are slotted holes to allow bracket to slide to the right 5mm. The yellow arrow is where i widened the slot to allow the lead of the cable to fit inside. The green is where i slid a bolt thru to hook the ring from the cable. The white is where i modified the 84 cable to fit in the 3800 slot.

While some of you might do this job in no time, for me this was a good day's work. i also found the other bolts and nuts from the fuel rail, they were lost in my parts bin...

Engine is in, all wired up, vacuum lines run, won't run on gasoline. Quick start causes her to run. Gonna test the wiring to the injectors to see if they are firing. Still, i am happy that Freya looks like a car again, not a pile of parts in the garage.

Thanks to all that have assisted me in this endeavor.

Freya is back on the road with her 3800SC. Still some hiccups but she starts fast, shifts easy, sounds good, not too loud. Maybe i will post some pics of her build.....

from an RPM perspective?
5500 - 6000 is yellow and 6000-7000 and beyond is "danger to the manifold"

Thanks Prodigy. i got on it last nite merging onto the freeway, and was listening to the whine of the supercharger and the motor cut out. i backed off on the throttle and she fired right up. Then i noticed i was in the orange of my GT speedo. Thats why i am asking today.

hmm, there is a rev limiter, I think set to 6000? been along time since I've checked..
but I dont think that would shut you down...maybe a speed governor? how fast were you going?
