Will this motor have 308's?

[jasontlit]

Sooo, it is 1/2 price weekend at the junkyard.

I cruised it HARD, and spent some time trying to identify some 308 heads.

I did a few searches here to try and answer my question(s), but am still not sure about what I saw today.

So, when were 308's getting pumped out of the factory?

Any other tell-tale sign of them w/o pulling a head and looking for the casting # underneath?

An otherwise stock 318 will never have 308's...right?

Will a 1992 vintage 360 have 308's? On that particular motor I didn't see any exterior casting letters or #'s.

I did pull valve covers off one 360 and a bunch of 318's, but didn't find any #'s tht confirmed a set of 308's.

Fianally, would my 340 like a set of 308's? Some specs are in my signature.

Thanks!

The 308 heads come on 87 to 91 360.these are suppose to be the best non W,non magnum heads out there.1992 360 were magnum engine so you wont find a 308 head on 1992 and later engines.i think your 340 would like them if they worked good.help this helps

[eric414]

Oh if you buy the 576 head though MP and i believe is the same head as the 308.i used the 576 on my 10 sec 360

So, I went back to the yard Sunday (still 1/2 price weekend) and saw that some of the engine hoists weren't being used.

I grabbed one and pulled a 360 out of a 79 Magnum...stripped it down to a long block. I thought about pulling the 360 out of the '92 van, but the hoists are better suited for cars. The van firewall was looking to be a problem...and I was working alone so the magnum got the nod over then van.

Turns out the 360 is a re-man from Pioneer, and it is a 1984 vintage (no big deal there)...the only thing that is a bummer is that it has 302 heads on it. But, by the time I was looking at it that closely it was out of the car and for a price of $85, I'm not worrying about it that much.

It is going to get a full tear down, so who knows what'll end up on the top end! I'll probably go back soon and pull the van's heads...or maybe the whole motor. Not sure if the van motor is a Magnum style as the van may have been built in '91 for the '92 sale year.

Plus, I got a gauge cluster/panel and a pretty nice glove box door from a '69 Valiant Signet.

Love half-price weekend!

Hey, I'm in San Jose... grew up in Pacifica. More info on this half-price weekend? Which yard(s)? Unless you don't want to give away your secret to fellow Mopar guys. I'd love to have a rebuildable 360 for $85!

Magnum engines have 10-bolt valve covers and port E.F.I, LA engines have 5-bolt valve covers (same since the 273) and throttle-body E.F.I (since 88, I think.) There are other differences but the valve covers are the easiest way to tell the diff.

[jasontlit]

I grew up in Pacifica too! Linda Mar. Terra Nova class of 1986.

The sale is over, but it was at all the Pick-n-Pulls...even the ones down in San Jose that I never get to. Even without a 1/2 price sale a long block can still be had for under $200...if you don't mind doing the work.

Dodger1: thanks for the info. The van motor definately is the old style (might still have a roller cam?) Who knows...maybe I'll be yanking that one too!

EFI since '86 !!

[racintracy]

Another easy way to tell a magnum engine is the massive beer keg lookin intake. You can see the thing sticking up form 50 ft. away.

[jasontlit]

My RC has that intake...I just wasn't sure if that was on all the new style motors.

[swingin72]

Uh oh... I went to Oceana... rival schools! Not really though by the time I got through (class of 98) since we no longer had any sports (lame ass decision IMO).

Pick-n-pulls... I've only been to one here in San Jose and they seemed to be really pricey. Wanted $9 for a little piece of trim and $45 for a side mirror that they wouldn't even let me trial fit on the car I had in the parking lot. Seemed like real bastards. Maybe I'd have different luck at a different pick-n-pull location (there are 3 in SJ I think). Not too many mopars either although I saw a kid pulling disks from a 73-76 dart. Good find for him!

um um um, a 302 head is a 85-91 318 (small port head) as far as 302's on 360's, i never seen any, do you have a 318? or did the re-man guys put 318 heads on a 360?

[dwc43]

Common to find the wrong heads on a reman engine.

[TK]

yeah, i was just asking though, in case he thought those were 360 heads.

[jasontlit]

No,...definately 302's on a 360.

But, like I said for 85 bucks I'm not too concerned.

I was just in such a hurry to pull it that I didn't bother to check which heads it had.

I didn't even notice the Pioneer warranty badge on the heads freeze plug until the day after! HA HA!

Is the only difference b/w 302's and 308's the intake valve?

[TK]

port an dvalve size, 302 a small port 318 head, good head, for a 318. i bet that 360 was snapp y at low rpm!

[dwc43]

Better find some 360 heads if you want it to make any power after 3000 rpm cause that's about all you'll get with those 318 heads on a 360.

[jasontlit]

Yeah, these heads will probably go elsewhere.

Who knows, maybe a set of Eddy heads will be in the future.

I have to figure out what this motor's purpose will be....does it go in place in the Challenger...or rebuild it and and put it in a 340 Duster I'm thinking of picking up from my friend, because the 340 in the Duster is about to die.

decisions, decisions!

[TK]

hey! they can go up here! i only have a couple sets of 302's! the 302 is a good perf head for a mild 318, it is what they called "swirl port" the only drawback is the pushrod hole is into the intake port pretty bad, so, if your hogging out a head, the old 675's are best. but, hey! wanna sell them? i bet someone on here could use them!
why do you want 308's? they have the same intake problem that the 302 has, actuallly, its even worse on a 360, cause it overbreathes the begginning of the port.

[jasontlit]

Actually, I'm not positive I want 308's.

I read that they make a decent street head and the bigger intake valve is good for a 340/360 warm street set up (over the 302's smaller valve). But, as you said they both have the intake port pinch area.

$30 plus shipping and they are yours.
