Engine Power Show is gonna try to ultimately get 400 hp out of a 318
- Thread starter 273
- Start date

Stock low Cr 2bbl 318 with manifolds on their dyno did 186 hp around 4500 rpm and 275-284 tq from 1,500 ish to 3,000 ish their charts are hard to read. Sound about right from the couple of other dyno'd stock 318 out there. Pretty sad really, at least there's room to grow

Pretty low bar but I guess it's a budget type build
They did a multi level 302 VS 305 build ended up at 460 ish hp for both, they said people complained they left out the 318 don't know if they'll end up takeing the 318 that far.

400hp is a nominal 1.25 hp/ci.
Meh.
This was from over 30 years ago.
With a big 2bbl(650cfm)
This is with a 500cfm 2bbl-

Thanks for the link. It looks like a clean solid piece to start with. It will be fun to see what they can get out of it. Nice increase with some timing.
Not bad NA and just bolt on's. We'll see how far they go and how they do it.

I will say they picked the absolute worst year range 318 block to start with. If they would have crack checked that deck surface it would probably be in the scrap bin.

It's not just "bolt ons" they are boring/honing .030 and replacing the pistons with ICON forged pistons
I hope the do it in stages between stock to 400 or whatever hp, for most 318'ers 250-350 hp is where most will end up. But be cool if ultimately they wind it out to 7 grand like the 302 and 305.
And there isn't anything wrong with a 350 horse small block under the hood of our old cars.
The rebuilding this is just stock parts with domed slugs and a cam upgrade. The cylinder head choice escapes me at the moment but of course, that’s the power release component.
It’ll be good for what it is.

+.030 with a hone and not a boring bar?

I see they have heads with the AIR ports in them. 302's may be? It will be interesting what heads they use throughout the builds.
Agree, If you look at most muscle car small block dyno numbers there all basically in the 330-360 hp with 350-390 lbs-ft which is within the 318's wheelhouse without having to turn too many rpm's.
That hand held belt polisher is interesting as well.
Picking domes seems like their limiting themselves to open chamber heads.

Diamond abrasives
Yes and no since they have a full shop and are not rookie at anything really, machining or die grinding the dome down to shape and fit the chamber can be done easy enough though time consuming and not a quick and easy thing like printing instructions out.
Depending, ultimately speaking, the shape & size of the doom and a thicker gasket can possibly solve the problem. I’m sure they will not ignore the quench.
I forgot how much they overbored the cylinder. I was hoping for a 060 over bore.
.090 would have been awesome. If possible.
LOL
Just .030 with a hone.
Don't forget the 4 barrel 273's. Domed pistons (crude design) with closed chamber heads.
I'm pretty sure the ICON domes are designed to fit most of the available aftermarket closed chamber aluminum heads.

Maybe because you have it, most think that they are undesirable, too small throw away, like the /6. I have a '68 318 that I got for free, if I ever get to it, I will stroke it and it will run as good as a 408.
