This came in my youtube feed and thought it be interesting for people looking to build so called streetable power. The test is basically what power you can make with what many would consider a streetable duration 224 @ 0.050" basically to me the mid point between RV and Street & Strip and around when torque peak starts moving up in rpm enough the 1st level of higher Stall and deeper gears may start to become necessary.

Would make an all around decent package for most and with these examples 5.0l, 5.3l & 5.7l nothing crazily big and none have to turn too crazy of an rpm to make 312-440 hp just the right top end to go with it. No reason couldn't go a step down if you wanted eg.. 218 and give up a few ponies. With the right top end and a reasonable cam should be able to squeeze decent power even out of a 302, never mind 318 or 360 etc..



I dug this one up to show what a 5.0l in our case a 318 should be able to do with better heads/top end, 418 hp with a 224 & 0.050"

 
You will never convince me to build a 318. lol
If I'd have known what I know now I wouldn't have junked all of them 360's and 400's in the early 80's, at least a dozen or so. lol

No ones trying to talk you/anyone into building a 318, all these test show with the right top end and reasonable amount of duration aka 224 you can get decent power even out of smaller displacements, no reason you can't do similar with 383-500+ cid, but does show a 318 should be capable and not need a crazy cam, cr etc.. to make good power.
 
and the debate rages on... 400 hp 318...

"no reason why".... "could".... "should"...

this tires me, for i am weary. the cam wars left me battle worn, reasonable offers has ground me numb to outside influence... the great dyno races, any smarter man would've called it quits... but alas... here we are again.

Point of the thread ain't about what you can do with a 318 but what you can do with only 224 degrees of duration.

Plus there shouldn't be a debate if a 318 can make power or not but unfortunately there's people out that thinks physics happens differently in a 318 and some think the same with a 383 or even a stock stoke 400 :)

isn't about what you can do with a 318, immediately mentions 318 in the first post.

why 224? why not 225? or 223?

I mention 318 and 360 and etc.., point was if a wee 5.0l can make decent power at ok rpms with 224 degrees plus same with a 5.3l & 5.7l than for us with 318 a decent size bigger than a 302, and 360 etc.. basically meaning any V8 we got, besides 273 should be able to do well with the right top end.

nit picking obviously doesn't exclude other duration, he probably picked 224 cause it's a common duration and he had various dyno examples of it, point is you don't necessarily have to stuff a large cam in to make decent power, he made 375 hp with the stock 5.0l cam.

Well I'm glad were all are on the same page now and everyone now knows a 318 doesn't have a 4" bore unless your able to bore it out 0.090" :)

wellllll.... the whole "should make" and the "could" this, that and the other... yeah, if it had a four inch bore and comparable heads, it should make the same power.

apples to apples n' all that

Who said has do exactly as well as the 302 ? I said words like decent and good power never promised identical power, I guess we'll find out when NC dyno his 318 how well a decent 318 makes., Again not the point this thread.

you literally typed that.

and what's the duration of that cam?

oh, that's right... 236/242

again, apples and oranges

Show evidence where the 318 bore kills a lot of power ?

Got any evidence or are we going on theories of should and could. Unless you got any proof it’s just speculation on your part also.

you're the one that likes to race dynos and speculate. you tell me. i'm sure you have a graph? perhaps a chart?

also, define "a lot"

i didn't start the thread. i'm only asking questions. *shrugs*

How about you back your **** it with actual apples to apples proof

Your the one making this thread all about 318's

The thread supposed to build off the concepts Richard started but modified for our engines or any engine.

yes. yes. concepts that don't directly apply. gotcha.

unlike you, i've actually built the motors. i worked in a dyno shop. but that's cool, let's push some paper around and bench race some.

on second though.

*yawn*

this bores me. later, skater.
