v-6 in early A-body

[QUOTE="BillGrissom, post:"98% disagreement sounds like bad math." your post was 200+ words, I agree with 4, "it bolts to 904" 200x.02=98%
" The consensus I have read is that the V-6 Magnum was a temporary solution. Perhaps it continued longer because there were extras to use up." Alpar being your source? "Perhaps" would infer you are guessing.

"If that crank sensor bracket you show is factory in Magnum engines, that makes it easy. I assumed one had to fab a bracket to work on a 904 bell-housing. "No", I have never owned a Magnum engine, only picked parts from them at a junkyard." Assumed indicates you dont know, yet you are giving advise to somebody?

"While the 3.8L is a more optimal V-6 design, it won't bolt-up to a 904 (I assume), so would require using a Jeep 2WD transmission w/ probably the same custom tunnel mod's, plus one would be pioneering the engine controls. Is there something inherently different about the 3.8L that makes it a low performer? Mine has a modern intake w/ long runners, pushrods like a Magnum (and Chevy LS), but a coil-pack which is better than a Magnum but worse than current "coil on plug" designs."
More assuming, the NSG370 6 speed is larger than an nv3500, expensive $1500-$2000 used, and has a 4.45 first gear as well as 4.0 reverse, not a great choice for car. You again state "fact" that a coil pack is better than bomb proof Magnum ignition, which is the 3.8's Achilles heel, with common failures and not up gradable like magnums .

"The 3.8L "toner ring" slots are much different. Rather than 1 per spark, equally-spaced like the Magnum, it is a coded pattern of unequally spaced slots. The flex-plates suffered cracking (mine, see photo). Like the Magnum, the toner ring is welded to the flex-plate, which also has the starter ring teeth."
Again, even though I posted a pic clearly showing the flex plate as one piece without a starter gear, you state "fact" "like the magnum, the toner(tone) ring is welded to flex plate, which also has the starter ring teeth(ring gear)"....which is clearly incorrect.

You accused me of "fuming" which I was not doing, I just pointed out that most of the "factual info" you gave as advise was dead wrong. I spend 1/2 of my day taking calls from people that got their "facts" off the internet and correcting incorrect information about Magnums. I do take offense to people posting total bullshit about something they know nothing about. If you dont know what a factory crank sensor looks like, you have never looked past the valve covers on a magnum while pulling "left over parts" off ram vans. The thought of putting a 3.8 in an A body is completely ridiculous as the pcm is not swap friendly, it would be total fab job, much harder than tunnel mods to install 44RE, there are no motor mounts, trans has dump truck gear ratios and they were just not a great engine. No matter how you slice it, its a mini van engine and would be a nightmare to install or wire pcm to actually run. On the other hand, you can buy a whole Dak 3.9 for under a grand, it bolts in with $150 mounts, uses V8 radiator, parts available at 7-11, it bolts to 904(your moment of truth), harness is available for $500 plug n play and they are a fun economical bomb proof engine with a ton of aftermarket upgrades for cheap.

I dont know or care what you do for a living but I build magnum vehicles and I dont go on dentistry forums and tell people how to do root canals or crowns because I dont know anything about dentistry other than it hurts and its expensive. I could assume you just cast a tooth mold in stainless or gold and then glue it on but I am sure not going to tell posters that on the dentistry-help forum.com
Please stop giving info on subjects you know nothing about(magnums). The OP wants to install a cheap easy V6 in his early A and the 3.9 fits the bill to a T.
BTW My 1.8L Audi makes more power and torque than you minivan but I would never consider putting it into an A body and if your 3.8 mini van impresses you, you need to drive some more cars, perhaps a 3.9 2wd Dakota so you can then give an opinion based on experience.
