Since a bigger than stock size bore is allowed it should be a cakewalk.
3.79 stroke. Forgot about that one. A friend has a 340 based mill with that stroke.
If an NHRA stock class 2 barrel 318 can run mid 11’s which it does, 10’s are obtainable with $$$$. Steve Dulsich has built a few 400+ teeners in mag articles.
If it's a 318, perhaps he's just not been caught yet ??Just a few minor corrections, the car pictured is a 65 Valiant. It can't have a 318 2bbl because the 318 wasn't available in 65. I believe it's a 273 2bbl, running in Q/S. The index is 13.65, so mid 12's is more likely. There's a few 318 thermoquad equipped cars and a few 273 afb equipped cars running mid to upper 11's in stock. In Super Stock form the 273 afb and the 318 Thermoquad equipped cars often run well into the 10's.
Yeah, I don't expect a lot. I think post 3 was a good'n. I fully understand most will grab a 360 because they are just as easy and cheap to grab, so grab the extra 42 cubes. But I'm just looking at what I have already, and "why not just see" what it can do.... ???? .... was more of my thought. 275 hp 318's are all over. If I do something with this 318, I want it to be something a little more radical. Other than that, I'm not very interested.
The Enginemasters Challenge runs the engines from 2500 to 6500 rpm. Notice in the article that at 6500 the hp is still climbing. i'm pretty sure the engine in that configuration would want a 7000 (or more) rpm shift point. And a 4500+ converter. If you recall , B3422w5 said they installed a smaller cam before it went in his car.Here's the 477hp 318 B3422w5 was talking about.
Don't know why everytime people think a 318 has to be a super high winding unstreetable mess to make decent power, just needs a bit more rpm than a similar 340 which is only 5-7% bigger depending on overbore.

And yet some members swear by them, post about them and lead other members that there magical slide ruler calculations are perfect and if you’re fails, you did something wrong.NEVER trust online calculators! 100 percent wrong on my combo!

I'd be curious about why he thinks the calculators are bad. I'm guessing his car ran about a second slower than the calculators said it would.....And yet some members swear by them, post about them and lead other members that there magical slide ruler calculations are perfect and if you’re fails, you did something wrong.
It's just how people use them, like some rule of thumb calculation is more accurate than a dyno, which we'll never able to verify the 1/4 mile calculator since a dyno can't be trusted in their view.I'd be curious about why he thinks the calculators are bad.

Are you asking me this question?I'd be curious about why he thinks the calculators are bad. I'm guessing his car ran about a second slower than the calculators said it would.....
Not really, Rob. Rhetorical. I don't know anything about his combo, or why he thinks the calculators are garbage.Are you asking me this question?
You have a 318 that dynoe'd those numbers? Is it still 3.31 stroke? What head/intake/cam and compression if you don't mind ...Hey Steve, never had it down the track. 450 H.P./ 490 FPT.
W2's would be a bit more than I'd care to spend on this particular project. The other thing is I'd use the engine I already have, which is the '85 roller engine.
490 ft/lb with a stock stroke 318? That i would like to see (HARD to believe).You have a 318 that dynoe'd those numbers? Is it still 3.31 stroke? What head/intake/cam and compression if you don't mind ...
Flat tops near zero deck and closed chambers are a old hot rodder trick. It just works.'85 roller engine has the 302 heads and the 9.2:1 cr flat top pistons. 040th down in the hole.
That stock roller cam runs out nice with a 4 bbl on it. If you are lucky that early roller will have the long snout cam with the eccentric on it for the mechanical fuel pump.

the '85 will have a long snout and fuel pump eccentric because the 85's were carbureted.'85 roller engine has the 302 heads and the 9.2:1 cr flat top pistons. 040th down in the hole.

well, that's why I asked him for more specifics to see what the build is. Yes, a lot of torque for a 3.31 unless there is boost.490 ft/lb with a stock stroke 318? That i would like to see (HARD to believe).
Stock duration and lift of your choice? ?I agree. I have been considering using a stock class cam
a stocker cam does not have a "factory stock" durationStock duration and lift of your choice? ?
Uncle Tony is doing it (10 with 318) with Bottle rocket no...?
I know you have a recipe to make a measly 450hp 318. Let's hear some ideas.Since a bigger than stock size bore is allowed it should be a cakewalk.
