Good Streetabe Power

[cookietruck]

you literally typed that.

and what's the duration of that cam?

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

again, apples and oranges

As for duration, is a 236* solid quite similar to a 226* hydraulic?

it can be. it depends. lotta in's, lotta out's, lotta what-have-yous

 

[ch1ll]

limiting factor for valve size and cam lift to make high hp.

What?????????

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.

"Only" 224 degrees is subjective. Comparing to factory camshafts, that's getting pretty big. That's "about" what the factory 340 cam was and they weren't slouches. Especially if you use the solid lifter variety, you'll have something.

Sure it ain't small but it also ain't overly big, it's still in the range of being fairly streetable for most, just before what I'd consider more of a street strip type cams 230-250+.

 

[toolmanmike]

225° was always a line to cross for needing a converter and/or rear gears to help it out with a 318. 340's and 360's, not a problem.

What?????????

Think!!! lol

Think!!! lol

Not a big enough bore size difference to matter to either of those parameters.

 

[PRH]

Good streetable power?

500 sounds about right

When you get to a 2.05 or 2.15 intake valve size there is

Probably could with a bbm and the right top end, but I'm thinking where most live in the 300-450 hp range.

Here another interesting one for streetable power on a bbm 431hp 383
Comparing two HFT cams 214 vs 231 vs a roller 214 which gave the best of both.

There is literally no logical reason to ever build a 318 except maybe for fuel economy.

For the most part, but why does have to be logical ? Out of all engines out there is even the 360 the most logical engine to build ?

Thanks for correcting me, you're right. There's no reason at all to build a 318. Great catch!

 

[ch1ll]

When you get to a 2.05 or 2.15 intake valve size there is

Who would use those size valves in a stock cast iron head or stock block for that matter?

No one.

On top of that a 224 cam is not suitable for those size valves.

This thread was not about all out race engines.

 

[fishmens67]

When I was younger I would have done the modern hemi swap, that would be logical at the time.

Yes I agree there's really no reason to build a 318 over a 360 or whatever engine beside /6 and 273, other than you want to, all the reason anyone needs.

 

[273]

That, but really the most logical even though not a fan of the swap would be an LS, availability, parts, support, ability etc..

I thought it was, there's a dyno comparison for a BB 383. lol

Man your talking to a guy that had a 63 Nova with a 327 and 4spd for his 1st car who jumped on the Mopar wagon after driving my cousins 68 383 Super Bee.
You don't pollute a Mopar with a brand X engine, you just don't.

Did very well even with the small 214 FT cam, don't know why people are so anti 383.

You finally say something I can agree with.

Lolz.
I wouldn’t build a 318 coz the bore is too small for a 2.3” intake valve
