i got the same thing.....
and if thats case, as stated b4, they are the same, pretty much, i'm sure w/in about 10 hp anyway.
'87-'92 was all rated exactly but in fact, in '93 ford changed how they rated hp, in '89 there was different cam, '89+ was mass air, and minor changes in the exhaust throughout the years, '93 did NOT use forged pistons....again, nothing notably changed, but slightly different.
personally i think it's because the lt1 was available starting in '93 for camaro's and TA's, and the 5.0 could still kick it's ass, so by calling it 205 hp compared to 275 hp corvette motor...you know, kinda adds insult to injury.
so w/ that being said....if you want free or super cheap performance try this........
set timing to 12*-14* (use premium now, and drop if it's hot outside 12* is fine all the time and usually 14 is as well)
remove the intake silencer (if it still has one) bolted on the back of the airbox on the lt. fenderwell. then use a k@n filter in the box
use a 180* stat, stock is 192* and 160* is too cold, you'll run phat all the time.
set the tps to .980-.990 w/ key on/engine off
make sure the tb is fully opened w/ the foot to the floor from inside the car, not by hand(pull the tube and have someone stomp on it).....many many many cars from the factory need to be shimmed, and it's like your not fully WOT
next biggest gain is about $400 total, ring and pinion. other than nitrous, your biggest bag for the buck. i like 4.10's but some people are scared of them, and only want 3.73's
you can tell your stock gears by the door tag, "ax code" M=2.73, Z=3.08 , and E=3.27 (aod's only avail.)
ok, thats all for now.........i'm out of breath.
