How much horsepower can you get out of a Dodge 318?
It can easily make 400 plus horsepower and still has great street manners. If you’re building for fuel economy, the 318 beats the Mopar 340 and 360, hands down. The 318 was produced in three versions: polysphere, LA series, and Magnum.
How can I get more horsepower out of my 318?
IF you just want to make BETTER power than a tired *** old 318 has, that’s easy. Have the stock heads rebuilt with a 3 angle valve job and new guides, possibly even shaved for a little more compression, get a set of ****** headers, Edlebrock intake, a medium street strip cam say about 280 degrees of duration.
How much boost can a stock 318 handle?
You shouldn’t run any boost without the right fuel and no more than 4 PSI without dealing with timing. A 318 with many rigs out there is running as much as 25 PSI.
How much HP does a 318 stroker have?
At least that’s what we used to think. Two months ago, we did a theoretical build of an LA engine using a 318 as the foundation….Don’t Spend A Lot Of Cash; Try This . . .

Is 318 a good motor?
The Good And The BadIn terms of durability, the Mopar 318 is robust. The bottom end of most 318 engines used a cast-iron crankshaft, and though these are not as desirable as a forged crank, the cast-iron piece has proven to be very reliable.
Is a 318 a good motor?
Is the Dodge 318 reliable?
Will 360 heads fit on a 318?

What kind of camshaft does a 318 Mopar use?
Slide into your block any stock, non-rollerized camshaft from a 1980s truck 318, as well as the matching valvesprings and lifters. This very mild cam will allow your engine to maintain a nice low-end power delivery and idle as smooth as glass.
Is there a 5.2 liter Ford 318 Mopar?
However, close examination will prove the 318 (and its later 5.2-liter Magnum descendant) just as performance-capable as any 5.0-liter Ford, 302 Chevrolet or 340 Chrysler. Begin with any 318, preferably one manufactured after 1973; these blocks had far stronger forged rods than earlier units.
Which is the best cylinder head for a Mopar 318?
Mopar ‘302’ High Swirl Cylinder Heads The small chamber of these heads give your 318 a higher compression ratio, which is good for both power and fuel economy. If you need to build a low compression engine, these are still the best heads to use, but run them with dished pistons.
Do you need a core for a Mopar 318?
For one thing, if you already have a 318, it’s not “just as cheap” to build that 360. First, you’ll need to get a 360 core, which will set you back $250 or more. The 318 and 360 engines are balanced differently, so you’ll also need a new flywheel or flex plate and torque converter. Then there is fuel economy.
