All my questions into one topic; sure they've all been asked before....
Gonna be asking many questions here, so PLEASE bare with me.
First off, which set of heads are best? :
afr 185's, Victor Jr's or Trick Flow Twisted Wedge? If I got a stock 91 or 92, and stuck heads on there, would I get 50 horsepower?
Without changing the bottom end, and without having forced induction, what is the most horsepower I could get out of a 302?
What does H/C/I stand for? >_<
I hear of people boring out their 302's to a 306.... Am I missing something really obvious here, or is that a really small amount to bore an engine? Can someone explain this?
What are some of the best intake manifolds; is there a good combo (heads, upper, lower?)
What are some good 347 kits?
About what will the difference in compression be between 60 cc heads and 70 cc heads?
Do the stock 5.0's really have 300 ft/lb tq stock?
About what is a stock 5.0's 0-60 mph time?
Thanks guys, please help me out. I'm trying to learn as much as I can before I buy one in a few months.

RE: All my questions into one topic; sure they've all been asked before....
all those heads perform well, ive seen an article in some magazine where afr heads gained 40 hp on a completely stock 302
the bottem end isnt the weakpoint, the block itself is, on a stock block most people say about 450-500 hp
HCI means, head cam and intake
306 is a 302 bored .030" over yea it is a small amount, no real power gain either, you bore the block when you rebuild it,
cobra intake is good, upper intakes will all perform about the same
as for 347 kits/short blocks, there everywhere, try coasthigh.com and dssracing.com
yea 5.0s had 300 ft/lbs stock, at least they did when they were new, this was a long time ago, and depends on how well maintained the car is of course

RE: All my questions into one topic; sure they've all been asked before....
on a naturally aspirated 302 (not running boost or nitrous) the 165's are supposedly the best heads.
i wouldnt push a stock block over 500hp
people bore to 306 just to clean up the cylinders.
Trick flow makes some good intakes (street heat for low end torque, track heat for higher end power.)
the edelbrock RPM is a good intake (RPMII for higher end power)
the compression between the 2 heads will depend what pistons your running.
and the stock 0-60 time is around 6 seconds with a manual.

Wow, thanks for the answers!
AS for me asking about how much horsepower I could get out of a 302, I was really trying to ask how much I could get simply by upgrading everything (except stroking and adding forced induction!)
If I had good heads, headers, intake, 70mm tb, u/l intakes, rockers, exhaust, 24 lb injectors, fuel pump, pulleys, advanced timing, etc
About how much horsepower could would you guys estimate? Would that get me a solid 80 horsepower to the wheels?
Stock pistons, stock deck height

RE: All my questions into one topic; sure they've all been asked before....
it would get you way more than 80hp.
a decent H/C/I set up should get you that alone..
cold air intake (CAI), underdrive pullies, larger MAF sensor, throttle body, injectors, Fuel pressure regulator
so those things, (bolt-ons) im probably forgetting some other bolt ons.
but with just all these minor mods a 5.0 should be putting from 350-400 to the wheels.

Oh, you've made me a happy person! I knew I might've been underestimating a little bit, but dang! My extremely rough estimate for all those are about 3500 bucks, sound about right? No wonder people love thier 5.0's.....

Yea, did seeem a little high. Oh well, I'm an easy man to please. 
Thanks for helping me learn all this stuff. Did that price sound about right though? Think I could make 325 to the wheels?

325 to the wheels w/ a nice h/c/i package and all the minor bolt ons..... YES. But make sure you spend some time on your suspension because alot of people forget to go that. You dont need that much power to run low 1/4 times (if you even care about track times). But for ex: there is a guy on here who has 225rwhp and runs 12.8's w/ a beffed up automatic.
Also, make sure the first thing you do is swap out your gears; its the best bang for the buck. If its a manual I would recommend getting 3.73 or higher and if its an auto a I would say 4.10's or higher.
