No.
Don't try to.
Rip that turd out and replace it with a more powerful motor.
Like a 2 barrel 3.8 V6.
Not trying to slam your car(just your motor),but I had one of these bricks 10 years ago.Useless POS motor.Pulled it and installed a 2V 5.0 HO from a wrecked '82 GT;only supposed to be 157 hp,up from 110,but WOW what a difference.Cost me a total of $339.00,and all stock accessories etc.fit ,as did trans,exhaust etc.
A year later,a 351W from a pickup went in with a Crane cam,Edelbrock P.351 intake and a 600 cfm Holley 1850.Again,same trans(different flexplate).Car then ran low 13s,and the whole 5.8 pkg added $1196.00 to my $400 '81 hatchback
Get rid of the 4.2 and move on
Don't try to.

Basically,an '82 T-bird IS a Mustang.The entire front suspension,k-member,motor mounts/trans mounts,all of it is the same from '81 to '88 on T-Birds.Also the same as '78-up Fairmonts,'79-2004 Mustangs/Capris,some Lincoln Mk VIIs....
It would be EASY to do this,with junkyard parts even.I had an '81 Thunderbrick and eventually had the entire drivetrain and interior from a '90 Mustang GT in it.EFI 5.0,5 speed,rear end,geared of course to 3.73,and the whole dashboard.Cool car-on the outside it was white with WHITE VINYL TOP.Ran high 13s regularly.
The parts needed to do this would be stock 4.2/302 motor mounts,stock trans(C4),modify the exhaust if necessary because the 351W sits an inch higher;stock exhaust MAY no fit properly.You also need to change the flywheel to an early 302(pre '81) or any 351W.Then it's just drop the sucker in and go.See?Easy.
