A 340 cam does work great in a 273, 318, and came from the factory in all 340's and high performance 360s. A cam has so much to do with how your engine runs, I would always recommend calling a couple cam companies and talk to them. You need to be honest with yourself and all the particulars of...

My 66 Barracuda was born with a 273. When I got it there was a 360 in the engine bay. I wanted to go fast so I installed a 170 slant six :)

Hello all and happy memorial day, I have a 318 LA engine that I'm rebuilding, it ran fine but leaked everywhere. I'm using flat top pistons and the stock heads so my question is how big of a cam can I put in this with the stock heads? I'm aware I'll have to change the valve springs which I was...

Cool. Def keep me posted on any success or lessons... Is there a thread here on your project?

I have heard in my travels that, with a LA 318 the stock cam is best in terms of economy reliability and power. Stock lift on an LA 318 cam is below .400" I know most wont want to accept that but , I'd bet there is something to it. Without heads, ( and I don't mean ported stock 318 heads, I mean...

Hello there! I’m new to the group here and I came across your post. Been a few years I understand but I’m looking for some education on doing the same exact thing as you mention with a 5.2 magnum in place of a 273/ 2 barrel in my 1965 barracuda. If and when you have time of course, any advice or...

To be honest, I love everything old school Mopar. But the 318 is my all time favorite engine, for exactly the reasons I've outlined. A mild cam, a set of closed chamber heads, and they are peppy enough for daily beater duty. I currently have 20 318s, a few 360s, half a dozen 383s, two 400s...

I see it the other way around they unlock 80 hp. The stock 340 x heads are good for about 400 hp gross with a reasonable build. So say a stock 340 does make 275 hp gross so there's 125 hp waiting to be unleashed what's mainly holding it back, Cam, Exhaust, Carb etc.. why wouldn't they add...

I don’t bother recommending cams. For a long time now. It’s not the pissing matches that idk me but it’s ether splitting of hairs on similar cam specs or its wildly different and sometimes absurd cam recommendations. Now, if asked, directly or via a thread, it’s just a general recommendation...

that's a whole bunch of cam for a 318 with that compression... the heads and intake will support it and you likely already have a converter and gears seeing that you were previously running a 408. but, still, that's a bunch of cam without the cubes and compression to make the magic.

I like 318s. It's a 5.2L v8. Put good heads, cam, intake and it'll rip. Plenty of 500 hp LS5.3s around. A 318 is a good set of heads away from the same glory.

check the cam bearings.. they tend to literally fall apart depending on the year...

Well remember, 318 guys are always citing " budget" I figure if I need the 360 heads why not look for a whole engine....? I do realize the value of a closed chamber aftermarket aluminum head though on the 318 . I personally would not grind and port a 318 cast iron head unless I could flow test...

Never heard one person say the 1.88 valve 340 head was the way to go for a 340 and see people swap out the X heads for that ground pounding torque of the mighty 1.88 valve. To me you can't just look at the head it's the whole combo but especially head and cam being the main two factors. What...

Ok you don't like the 340 cam which is fine there's a ton of options out there, What about a comp cam xe250h with a 51* IVC or maybe grind stock one similar on a 108 if possible? Does anyone even make a stock spec 340 cam anymore?

I ran one of those when I pulled my 318 out of my 1976 dodge van and built a 360 For it back in the late 1970’s. J or X heads, aftermarket pistons and towing cam, headers and a 650 Holley. She ran and towed great.

on a 9.5:1 318 with ported 302's and a MP P4452761 (.450/.455 268/272 110LSA) with a performer RPM and 750 3310 i laid down a respectable 330hp @ 5750 with aftermarket heads and a airgap, i don't see why you couldn't be in the 350 range as long as keep the compression up. chasing much more than...

THat should be a decent combination with a old 340 grind.

Just filling in for Karl. . Pulled the heads off today. Going back together tomorrow. Debating if I should put it back the way it is, or put the Weiand intake and valve covers on I have been saving for the 318 Roller cam motor.

That's kind of what kind of combo I was looking at using.

Nothing will convince people to change their minds, if they aren't open to receiving, evaluating, and acknowledging new information. Some people are just stuck in their ways and perceive everything that doesn't 100% agree with them as some kind of personal attack. They just go into fight mode...

I have a 65 dart GT with a .030 over bore '68 318 with wiseco 10:1 pistons, comp xe274 H cam, dual exhaust (stock exhaust manifolds), dual plane weiand with 600 cfm edelbrock, '73 stock electronic ignition, balanced, high perf valve job, ported heads, carefully timed etc. and it is very fast...

Friend of mine raced dirt track, ran a 318 with 340 heads. Fastest car on the track.

The deal breaker for me is the expensive intake manifold needed for the Magnum engines. Your car uses a complex kickdown system that would have to be addressed. If the car is a factory air car-some of the compressor mounting points won't be there on that new intake. The electric fuel pump, the...

Right now there are two issues I am facing: stumble right off idle and major bog when secondaries open. Idle mixture screws set for highest vacuum (21" Hg). Accelerator pump in either position did not affect situation. Metering rods adjusted 2 rotations from bottomed out. Air valve wound up...

j heads on a 318 doze one fine job! have had 2 and both were screamers!!

Correct. But how far does he want to go and how much money does he want to spend on a 318? Unless he's going to add a roller cam, some exotic heads, turbo or blower, he's not going to make a huge difference from what he has now. That's why I recommended sticking with what he has.

What power level you trying to get? Sounds like streetaability is important to you so probably 0.8 to 0.9+ hp per cid about 256-290 hp. Not really that hard there's slightly different ways to get there, mainly different head and cam combos, less flow more cam, more under .450/.500" flow less...

Ill just say the 70s 318 is cheap or free for a reason...:)
