How much HP can you get out of a 318?
A street-worthy 318 can easily make 400 horsepower, about what a lot of street 360s put out.
How can I make my 318 faster?
the easiest is just dropping some used stock 360 heads on it along with some used headers and a 4bbl carb. The open chamber heads KILL your compression, but the flow improvement, along with the headers and carb can put you at an honest 300hp which is plenty enough to have a tire boiling good time in any a-body.
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 many miles will a 318 last?
Like any engine, it depends on routine maintenance and how the engine has been treated over its lifespan. Some may last 2 miles, some 400,000 or more. There are a few things that need attention at higher miles just like any engine.
Can a 318 be bored to a340?
just not possible. IF you want to use the 318, put a stroker crank in it and make a 390 out of it or build a 360 and be done with it. i’ve heard some say that the 68-69 la 318s you could bore . 090 over because of the steel that it is made out of and the walls are thicker.
How do you turn a 318 into a 340?
to achieve 340 cubics with a 318 you will need a stroker crank. yep, to get up to 340 with a 318 you’ll need a stroker kit. around 1500$ or more for a kit with everything you need, including the crank, bearings, pistons, rings, and connecting rods. Get a 360!
What is a 318 stroker?
Mopar’s 318 small-block engine is the ultimate sleeper engine. One of the most common Mopar V8s of all-time, the 318 is reliable, affordable, and readily available. Since most 318s are extremely durable too, the unassuming little engines make the ultimate foundation for a potent stroker engine.
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. It is worth the trouble to get a computer in it and get it done right so you can make twice the power.
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.

Can you put 340 heads on a 318?
The 2.02 valves on a 340 head are complete overkill on a 318 unless you are running it constantly in the higher rpm’s. The larger valves can actually hurt your low end.
Will 340 heads fit on a 318?
The problem with all the 340/360 heads on a 318 is the chamber measures about 70 cc, which will drop the compression to an unworkable low ratio on a 318. You can forget about decent performance with these heads and the stock pistons, so again, a set of moderately priced aftermarket pistons is the answer.
Are there different versions of the Mopar 318?
The 318 was produced in three versions: polysphere, LA series, and Magnum. Each are good engines, but for performance use, you should stick with the LA or Magnum because performance parts for the 318 Poly are hard to find. This article focuses on the LA version. Why Build a 318? Why build a 318 when it’s just as cheap to build a 360?
Which is the best head for a 318 engine?
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. Some builders report that for two otherwise identical engines (including compression ratio)]
What’s the difference between a 318 and a 340?
the la blocks where developed past the earlier a blocks which stood for alloy la standing for light alloy. the 318 and 340 are almost exactly the same except for bore size and the 318 used cheaper parts. to do a successful 318 build used a 340 forged crank 340 rods will fit as well
Which is better Honda 360 or Honda 318?
Then there is fuel economy. Almost 12% smaller than the 360, the 318 should get about 12% better mileage, all else being equal. When it comes to building for power, the 318 is also a great choice.
