If you can't get a 9.5 360 with a xe268H to run on pump gas, you need to turn in your man card. FFS

maybe not turn in your man card, but somebody should definitely take away your tools at that point.

1989 was the first year for roller cam 360 block. Just picked up a 91 360 with 110,000 miles the other day. Haven't pulled it apart yet.

That carb is leaving 20hp 20 lb ft off the build

360 heads are open chambers. You cannot get any Squish/Quench out of that combination

I believe Jim Laroy has made north of 700HP without squish or quench. Not only that, but millions upon millions of engines came right out of Detroit without either and some were pretty dang hot. The 440 Six Pack Engine was but one of many examples. I'm not saying quench doesn't have benefits. I even have a quench built slant six on the stand. It's not the end all be all for making power, though and you shouldn't come across like it is. Maybe you should try helping people use what they actually have instead. Just a friendly suggestion.

Ok, cool. Thank you sir! My knowledge starts thinnin out the later model the engine is.....but then, my knowledge is pretty thin to start with. lol

Milling of the heads will take care of that.

To the both of your replies…

Your correct. My understanding is that the crate engines were .020 over for this reason. And Mother Mopar added cooling ports along both sides of the upper center head bolt boss...Mag'n the block is mandatory.

I have a stock 73 Dart 318 automatic that I would like to get a little more out of it. I am not interested in fixing up the 318 at this time. I have gathered the following parts, an 86 360 that needs to be bored 40 over. 360 heads with 202 valves, Edelbrock dual plane intake, Edelbrock 600 carb, Roller Rockers 1.5, MSD Distributor & MSD 6AL2 box and coil, Headers & 8 3/4 Suregrip 3:55 gears. I am looking for a mild build. I am looking for recommendations for pistons and cam.

I have some H405p ? .040” pistons I would sell to you for $160 plus shipping.

1.637" compression height, 0.984" wrist pin, and 5/64" ring grooves

Is the 86 engine a flat tappet or roller LA? If roller, that's a lot of territory already covered.

I believe 1986 is the beginning of roller engines for 318’s and 1988 is the beginning of roller engines for 360’s.

Is that a roller block, and do you have the roller lifters, dog bones, and spider to reuse?
What heads # do you have.
You can't go wrong with the aforementioned kb107 pistons for price, but even though not a big horsepower loss, I still personally avoid 5/64 ring packs anymore
