318 Stroker????
« on: June 28, 2009 - 08:32:52 AM »
Does anybody know anybody that has stroked a 318?
It looks like there are kits to go to 349-355 or 390. I've got a buddy that says that would be like building a time bomb. I also hear that when it's all said and done from a $$$'s standpoint, I'd be better of with a 360, a cam, and some good heads.......................

I'd really like to have close to 400 HP and some torque, what's the cheapest, easiest way to get there?
I'm in northern (Elkhart) Indiana if that make a difference, I'd like to work with someone within a couple hours driving distance.

Since 360's are so plentiful and cheap I would start with that as my building block.  Bigger is better.

You can go big with 318 these days. Whether or not it is a time bomb depends on how you build it and how you use. For a street cruiser use it may last a long, long time. With premium parts it may last a long time. As a high rpm screamer, it may not hold up.

Yes, starting with a 360 gives you more inches more quickly, which reaches big numbers more easily. However, using that logic, swapping to a mildly built 440 puts you over 400 horses with a comparable amount of torque with a good solid rebuild and only a few speed parts that is all available under 5000 rpm. That is why big block are so popular; big power easily achieved.

The problem with 440's is they are harder to come by than a 360.

I agree that cheap 440s in salvage yards are not always easy finds these days, although 383s are still easy pickings. Usually best bet is to ask around. For example, I've got two 440s sitting in my garage I'd part with at a reasonable price, but all my local advertising has not netted any takers. At $200 and $500 you'd think they would be gone, but there they sit. So get the word out locally and you might be surprised what pops up.

451 / 400 block has to be the cheap way to go , 400 are cheap to get &with all the strokers a good 440 crank & rods are easy to get as well , but then you have to change the tranny ,mounts & rad so the cost increases , 360 s are cheap & everywhere ... your call

360 looks like the way to go, but I still wonder, does anybody know of someone that used a stroker kit on a 318?

I know a couple guys with them. They are out and out better than any 360. But, you need the same better heads to get the power there. 318 heads are not enough. A set of mildly ported J style, or RPMs will work well. They can be stronger than any 340 or 360 too, because there are some 318 blocks that have a lot thicker bores. Around me, any engine can be gotten pretty easy. It comes down to cost... 340s are $500 for a good std bore block, 360s are about $100, and 318s are free.

moper,
It looks like there's 2 basic 318 stroker kits. You can go around 350 Cu. In., or 400 Cu. In., I'd be concerned about heat and wall thickness at 400.
 At around 350, it seem like you could have a great ''little'' motor. But you need a Cam and some GOOD heads to make it go.

Can you get me more info on the 318 builds you've heard about?
THANKS!

I didn't build them and these are "pen pals" of mine... so my info is not first hand nor very complete. But, I can tell you one moves the '68 B body it's in to high 12s on skinny tires and pump gas in WI. The owner loves it, it looks totally stock down to the Quadrajet on it (the fuel enters the front like the factory 2bbl) and the single snorkel air cleaner that was modified to fit the 4bbl neck. It's the 390 setup. (4" stroke) He also knows very little about how cars work..lol. So asking for details is kind of pushing it with him...lol. The other one is in FL, he's on Moparts under teh name tbFlyer or soemthing like that. His engine's been thru a couple incarnations but I believe it was in a Diplomat and he loves it. I agree on the bigger inch package. The 4" is fine IMO and is a great balance between power and longevity. I had one planned for my truck but then changed my mind to stay with the LA 360.
