Default engine swap

I have an 86 F150 4x2 that was originally a 6 cylinder carberated engine that now has a 84 302 HO motor with a Cam & headers and a 600 CFM Holly Carb. I want more power should I go with a 351 crate motor? The 302 rear main seal is leaking pretty good. The transmission is a Tremec T170/Clark 4 speed overdrive. How much power can I accept without tearing anything up.

A 351 crate engine sounds like a nice bump in grunt. As for the trans, Go0gle it and look for it's torque rating/torque capacity. They can differ sometimes depending on what 1st gear ratio they have... I know the T-5s do.

Have fun. I remember those days of engine and trans schwappin'. Did several over the years when I owned a '63 Fairlane hardtop. The zenith of that enterprise was a 347-inch 302 making 395HP and 420 lb.ft. and running that through a late-model bellhousing (and a cable clutch linkage), a FRPP King Cobra diaphragm clutch, a Motorsport T-5 with a 2.95 1st and a Bill Thomas-built 8" 3.80 Trac Loc. Car was set up for twisty roads rather than the drag strip and with street radials and no traction still ran 13.6 @ 107 MPH.

Blah blah blah... good times.
