I did a 351 on a tight budget for a daily driver, after I gave up on going 393 when gas prices went crazy some years ago.
Only 170cc port 1.9 intake valve Performers, lo miles used for $600 is why, Explorer top over
Ford GT40-351 lower just port matched, (those GT40-351 lowers are hard to find cuz Ford quit making them quite awhile ago so for a mild driver I'd go Edelbrock Perf or Perf RPM efi upper over their 351 truck lower for good street throttle response & torque) stock shortblock for 9-1 comp ratio with the Perf heads, shorty headers, 2-1/2" catback. I started with a stock HO cam and put it on the dyno just to check air/fuel ratio. Cam was WAY too small even for a driver, so
it just went 315 hp at 5200 & 340 tq at 4200 with an AOD which sucks lots of power, even with 1.72 roller rockers. Then I switched to a trick flow stg 1 cam, still with the 1.72 rockers and it was night and day esp above 3000 even with the small heads. Never did dyno it, but was an amazing difference, so I figure maybe more like close to 340 hp and 360 tq or so. With the small heads on the 351 it starts to choke out around 5k or 5200, could use bigger heads. But budget budget budget. At least is fun to drive and gets good mileage on my long trips.
Definitely go a good quality roller timing chain setup like Cloyes tru-roller. I went with a different supposedly good aftermarket set but when I changed cams at only a few thousand miles it was already sloppy. And go stock capacity oil pump, hi flow or press just robs power on a driver motor and a stock pump is plenty adequate.
If you're roller cam, you need a 351 efi distributor. Only the last couple years had roller cams in 351's in light trucks, for the steel gear. Swapping gears is a royal PITA. You can figure out which motors had roller cams oem by looking at lifter listing in i.e. O'Reilly's website.
Here's my swap write-up.
It's into an 89 Lincoln Mark VII LSC, but that's pretty much just a longer Fox chassis.
Lots of little tips in there you don't normally find in swap articles. Also some good links.
