CRAP!!!! Might have been smart to mic the bores before I started. This one is allready .040 over and well worn, so looks like .060 over it shall be. This block does have good sonic check numbers, the thinnest spot I found was .220 so I'm not worried at all.

I think this 318/328 engine will surprise some of the Naysayers.

Thought you already had pistons? Do you have a set of 060 over?

I allready had the .030 over ones here, but the only other 318 core I have is fully assembled, so because I'm lazy, mostly, I just ordered .060 over ones. I will most likely have to weight match them to the .030s but that's easier than tearing down another core.

BTW, you have your own dyno also? And i have my own business, it's nice to be able to tell a customer... i don't think this is the right place for you.. There are some you just know will never be happy

No, I have to go to another shop for dyno testing.
 
And to circle back to what was discussed previously, I have decided I'm going to use the speedmasters "out of the box" although I will check seat/valve runout and guide clearance. So it will be very representative of what could be done by anyone, no special machine work, no porting, and a shelf cam.

This is gonna be interesting to see the results of
 
That’s a good plan, and about the minimum for bolting on a set of heads OOTB.
 
Just read the thread.. i wasn't around when it was made. Did you ever pick a cam? i overcammed mine a bit i think.. kinda love the little 318 with trickflows though it moves pretty good for what it is.

I was planning on a custom grind, but I think I will forgo that, I like the idea of a bolt together "catalog" parts build. Summit has a comp solid flat tappet in stock, it's a 236/242- 502/511 and I plan to use 1.6 rockers for a theoretical lift of .534/544 (minus lash) but I believe it will work well

yeah, i like the bolt together from standard parts thing.. it's what a lot of us do.. and that cam is actually a little bigger than mine. i'm horrible at picking cams :)

How driveability, part throttle response and off the line ?

Been near perfect, for how bad it sounds it hasn't given me any issues in drivability at all.. plus that street demon makes life easy

Having firsthand experience with what he can do with a pile of parts, I will guarantee you that this motor will surprise people.

So internet wisdom is wrong again then lol.
A low cr 318 with fairly large ports and decent size cam can perform and have reasonable driveability who's gonna tell AJ ? :)

AJ and i had a long conversation bout my engine.. he is a smart guy.. And yeah my idle is stupid lopey but off idle, tip in and driving the motor is honestly one of the happiest motors i have ever had and the only tuning i have done on the carb is putting in the lightest metering rod springs i had due to making low vacuum

That’s gonna be rowdy on 318 cubes. I like it. It’s almost the same specs as one I put together.
 
People who aren't familiar with the build will never believe it's a 318.
 
I would like to see a stock stroke 318 with good piston’s, forged lightweight, with enough port, cam and carb to make 450hp. It’s very doable I have built a 292cid 289 W Ford that makes 455hp at 6200rpm so I would like to see it done with a little mopar. My little Ford makes 90 percent of its peek torque by 3000 rpm.
The little Ford has a great idle at 725 rpm so no crazy cam here.
I think the 318 has been the under rated two barrel for ever, so a nice 450hp lower budget build to show how much they can make would be great.
