Sometimes that is true yep. Maybe me and dustin should go hit a race or two, see just how good a 351 efi with an auto does against a little ol 302 with a manual 
Ive always kinda thought the stock 302 vs 351 worked like this, the 351 does have more power, but doesnt quite had the speed factor. Thats just from the few 351's Ive raced against when I was young, and thats not many.
Ive beat my buddies 91 f150 4x4 with a 351 auto. Mine has stock manifolds, well stock everything except the custom leaky exhaust, and his had headers and sweet dual exhaust. So stock for stock, in the speed department, you might be surprised!
I cant stress enough how much power an stock auto tranny takes away from an engine.
But you probably know that, right?

The one with the tinted windows will be faster...
Seriously though, I think stock they would be close but mods then the 351 may come out on top. I've seen a stock 86 302 be even with a stock 84 351 4V. Could be interesting!

i don't mind heavy if its tough, i should look into some shift kits though, and some sort of friction eliminator if there's such a thing...

Like collin said, there are tons of mods a guy can do to them to make them better.
Unless I go with a tranny with OD, when I build that 460 and put it in something, Im gonna have to do the same thing, build er up tough.

there's so much difference from the c6 era tranny's compared to todays trannies though... the '83 kick her down and it goes instantaneously... the new stuff has a little too much slippage for my liking...

You can fix all of that though. They arent supposed to slip either, so quite possibly you drove one that needed some repairs too!
I forget which one, but I THINK its the e4od that is basically a c6 with an overdrive put in it. Computer controlled of course, D'oh!

maybe slippage is the wrong term... but you know what i mean... its not an instantaneous whomp, roar... its a slower, more hesitant, impossible to describe movement... nature of the beast, not a problem...

Yeah the old ones always had more of an instant kickdown feeling but the newer ones seem slower. I know my 04 has that delay due to the electronic throttle but apparently a tuner like an edge or something gets rid of that.

Like when you pass someone and don't need to floor it, just give it some gas, there is a delay before it shifts down. It is more that the throttle response is sluggish due to the delay between the throttle pedal position and the actual throttle blade opening to where the computer tells it to be. The old throttle cable was better IMO, but a tuner could make the new ones feel just as responsive.
