Re: hp #s for 351 and/or 302
The 96 and up 5.0 HO all have about 225hp. But they are very easily built to whatever HP you can afford.
You can easily get 300HP/340ftlbs with well chosen bolt on components, a good choice of cams, and port matching the heads. I had mine Dyno'd in Vegas at about 275hp at the rear wheels, but that was when I was running the E303 Cam. I have since swapped in a B303 cam which gives up a little HP for more torque and stronger power band in the lower RPM range. My engine came out of an 89 Lincoln Mark VII has about 89K miles on it, and nothing more than bolt on mods, and port matched stock heads.
My engine is very strong, it can easily idle in 3rd gear at 400 rpm under heavy load, then excelerate to 3000 rpm in about a 1/2 second without side stepping the clutch. It is about as good a rock crawling engine, as you could ask for.
