Can't edit. Might as well post the rest of the stupid vids. I don't think it dies at 4000RPM though.. I kick it at 4 grand in this video:

Here's the rest. Crappy, I know.

I don't think that kind of RPM is doing you any good , but if you build the motor then 6K is no problem for a 302 & will get there quick with the right gears... Lew

Right. But is it 'dangerous' for the engine in its stock form? And I'd love to have some 4.11's for my 9".

Just one of my 5 vids or so. Just showing it goes to 5k easy.

Yes, I'm spinning all through 2nd gear. I just held it at 5K RPM.
Wow, that is impressive! And think, a few internal mods and you can be revving to six or seven grand and be making power.

Yeah, I want to do some things to it, but dunno when I'll ever be able to. I'm thinking GT40 heads, headers, true duals, and around a .480-.500 lift cam with around 212 duration at .050". Not too much duration, I want some mid-low range power.

But, with my luck, someone will total my truck before I ever get to play with mods.

Don't talk like that Homie. It's never good to talk like that.

302's have a lot of aftermarket. You could really get some impressive power out of that thing. You're not from 200 horse already. A little money and you can be seeing 300 horse. True duals seem to really open up V8's, assuming you have headers. I like glass packs for V8's; I don't care what anyone says, a glass pack still flows better than a baffled muffler. Thrush glass packs have a 2'' inner core. Cherry Bomb's are supposed to be more narrow, that's why I'll only run Thrush.

Have you looked into adding OD to your tranny? Add OD and you can add 4.10's to your arsenal without hurting your fuel mileage too much.

If you ask me that motor already has a cam in it.. stock flat tappet 5.0 truck motor does not like to rev like that one... assuming the tach can be considered accurate.

That would be the 305 and 318 you're talking about.

Now those are two V8's I'll go head to head against.

I know without a doubt a 300 will out work a 305. Don't know about the 318. I think the 300 would simply be more efficient than the 318.

I don't know about that. Carb to carb, a 300 makes more power than a 318 in both horse and torque. I can't see a 318 making more than 180 horse with EFI.

Bah, let's just get a big get-together in the sticks. You know any Dodge guys with 318 powered trucks? We'll all bring some foodz and drinkz and see what's what!

lets not talk about 80s carb motors, since all across the board from every company they were terds. the efi 318 magnum however, made 230hp and 300ft lbs. which would lead me to believe it would be a fair fight for a 351, if dodge's transmissions werent so power robbing.

Holy crap, really? How did the 318 go from 130 horse to 230?

look up 318 magnum, in 92 they redid the whole motor with new cylinder heads, and of course efi.

The 80s motors all were really crappy from dodge, with the exception of the cummins, because this was when chrysler was just coming out of the brink of bankruptcy, so they just put everything together as cheaply as possible which made for really unimpressive engine packages.
