Subject: FTE Perf - 302 or 351 ?

I know I usually have tons of quesitons about FE's, but now I have one
about the Winsor family. Usually I can adlib this stuff since we have a
couple 70 302's and 69 351W's and just go look, but this is a bit newer.

My sister's truck lost oil pressure, and by the time I shut it down the
lifters were clicking. A dealership restarted it and claimed that the
motor was "hammering" Since this is my sister's truck (91 F250HD 4x4),
Dad's gettin antsy and wants to be sure she won't have any problems with it
on the road when she gets it back. She's got a 5.0 in it, its nice enough,
gets decent mileage and has enough power to move at an okay clip. But I
tend to think its a bit underpowered, especially when compared with my 73
w/360. Obviously since its a 91 its got all the EEC and multiport fuel
injection on it.

Now for the real question ... what would it take to swap a 351 in place of
the 302 (assume longblock switch)?
I'm pretty sure intake (lower), but what about the oil pan? Heard rumors
that those need changed. Computer module ? Sensors?

To add to the mess we've got a 69 Cougar with a 351 that dad just re did
... it is a 69 351 also ... how big of a pain to swap this long block for
the 302 ? Probably a much bigger pain, but just interested in seeing how
much work it would be.

Thanks to anyone who can help me out, I'm sure my sister will appreciate it
too :)

Deck height and CC changes dictated the valve geometry. When I rebuilt my
first 429 with parts from PAW, I used the wrong length and shorted the cam
lift and it's durations. I knew the block's deck height, piston stroke and
head CC. Like most back yard mechanics, my primary goal was to get it
together so I could stand on it. Took me awhile to discover the valve train
is the most important consideration in a quest for easy HP. Thanks to the
lists and some further experience, I won't put any more money into a
performance engine without using a measurable pushrod and ordering them cut
to size.

These are listed backwards, aren't they? As deck height increases, I would
think the pushrod's gotta be longer to reach (assuming the heads aren't made
shorter).
