Stock 6L 4l80e flexplate Strength How strong is the stock flexplate?
I will be making 550 crank N/A and later hope to make 700 - 800 with a turbo
Heavy 6k lbs street truck, gonna get a semi-built 4l80e behind it at some point

See if you can find a 6 groove, 3" diameter pulley to slow down alternator.
try a Delco # 1986832
Pulley was stock on 85 Buick with 94 amp 12SI
You can probably get it to fit your AD244, that's what I use on 4.8 Liter that likes to REV

I still gotta tig weld the cracked part of the trans case where the top bolt goes through, But yeah I'll make sure to get everything in just saw a video someone was replacing a motor because they didn't put dowels in with the trans. probably didn't have the right clearance flex plate to TC either.

they got a high performance / HD one on rock auto by pioneer. Called the guy said the 2 are exactly the same and rated for 500hp and SFI certified where as the stocker is rated for 350. should I just go this route even though I may eventually make 7-800hp crank or should I be getting billet?
the price is real good too, but I've always wondered why the aftermarket stuff is only 3 bolts not 8
EDIT - just gonna buy that when I order some stuff from rock auto, people have been runing them to 800whp I'm sure it will work fine on a street driven truck
