318 with 360 heads and compcam build help

[mygasser]

Speaking of cars, where’s your A-body Dan?

 

[66fs]

That's what I have said before, only thing is that there's only one piston and that the KB and I think that it's CH is 1.810" The other pistons are forged and he doesn't need those for what he's doing

You would do well to read a whole thread before jumping in at the end. There are many ways to gain compression, milling heads, head gaskets, decking a block, but if you are buying pistons anyway, you can skip all that and the headaches and expense that goes with it. You just have to do some research and figure the combination out. AFTER you decide how you want to use your car.

 

[66fs]

HOW DO YALL FIGURE THIS OUT. Is there a class I skipped or something?

Most of us learned by doing, either for ourselves and/or others. If you want a little education, call someone about a custom cam for your engine and car. Racer Brown, Isky and others guys here can recommend. They will start with what gas do you want to run? What car, how much does it weigh, intended usage, gear ratio in the rear, standard or automatic transmission? Then you get into the engine: cubic inches; head castings; compression ratio; carb; exhaust? And I'm sure I'm missing something... There are drag racers, street strip, autocross, and street, and they are all different.

My old 318 in my dart. 75 318 bearings and rings. Isky 270 mega cam 221 at .050, .465 lift on a 108 Lsa. Stock 360 heads shaved .050. .028 head gaskets. Performer intake and 650 dp . Stock converter and 3.55s. 3550 lbs. stock 14in. Tires. Had to come out of the hole easy or would spin badly. 2.1 60ft. 14.0 at 100mph. A converter and good tires maybe 13.50s

I guess this is what I was asking I’m more looking to mimic someone’s build that I know has worked.

Speak to text. Pretty sure he meant FOR 700 dollars.

I was pretty sure I said I was using voice command and things usually get wrong...
Is that yay-Who dan the man? Still not have a car or any experience.And i'm still giving you out advice???...
Good Lord The last person the young man should be listening to....

And you’re right behind Dan. The real number 2.

Agreed... There's people on here that give top fuel eliminator advice only, and if you don't follow it, you are a fool... (to them...)
Maybe he should just put the cam in there and find out what happens.That way he gets to learn something...
It's not like it's gonna blow something up..

Exactly

I guess this is what I was asking I’m more looking to mimic someone’s build that I know has worked.

First, what are we working with ?

Is the 70 Swinger on the road or in a 1000 pieces ?
Is the 67 318 and 8 3/4 already in it or is it still a slant 6 car ?
Have you done a Compression test to the engine ?
What's the condition of the engine?
Is the car stock or already got some modifications ?
Are you willing to upgraded gears and stall, if so how far ?

What's the budget ?

 

[Scody21]

It's possibly in California as I'm going to be bidding on it

But would you fly out and get it? I’m in your neck of the woods, just got a Kenworth and Trailer in KC. Like right now in KC…. If you really want it you have to JUMP on it… Going back to Cali, Cali, going back to Cali…..

 

[273]

Can we stop turning every thread DTM post in, into will he won't he buy a car.

 

[273]

I'm willing to bet you that I can give him advice on how to build his 318 and he would be satisfied with its performance. You seem not to what to give me credit for anything.

Why you so baffled by this, lol

You've done a 1000's threads asking us how to build a mild 318 over the last few years, haven't done it, now try to school others, including the ones that tried to help you and you can't figure out their frustration with you, same with this buying a car non sense.

 

[273]

I'm far it. I can't say anything and somebody always has to start something

Your in between a rock and a hard place, you made this messy bed now you got to lie in it.

That was for jpar because he insulted you.

You are far less of an issue that that liar.

Keep your head down and keep learning.

You could give Jpar advice but true to form he wouldn’t listen.

 

[Dartswinger70]

Ill tell you what an old feller told me when I was about to slap 360 heads on a 318 the old coot said" If ya do that you'll kill your compression..."

 

[junkyardhero]

Use the cylinder heads that he already has... clean up the bowl area and short radius side

can you expound on this? i don't understand. specifically what do you mean by "clean up the short side radius"? how is this done and what are the benefits.

be as detailed as possible, so that i and others can follow.

 

[junkyardhero]

I guess this is what I was asking I’m more looking to mimic someone’s build that I know has worked.

step one: figure out what you want. but this is the kicker, everybody thinks they need that 400+ hp johhny kick *** motor that "has that chop" at idle.

and that's where most engine builds begin to unravel.

be truthful with yourself about how you drive, how you use the car, what you want the car to be, how you would like to use it in the future and what your expectations are. and i can't stress this enough, you have got to be *realistic* about this.

do all of this before you even start *thinking* about budget.

once you're got that, then you can start looking for a recipe to copy that's within your budget.

 

[66fs]

Okay so say I sell the comp cam kit and the 360 heads and the 360 block and another 273 motor and a few transmissions I’ve got in my garage now I’ve got some money. And my parts list looks a little different now it’s a 318 with 318 heads a chinesium 4 barrel intake a couple Holley 4 barrels and a 4 barrel edelbrock carb I want some more performance what do you suggest I do to raise the performance?

Ok, what raw material do we have right now? Engines, what year 273, transmissions, rears? All to go in a 70 Swinger. Is the 318 in the Swinger running now? Pictures? Sell the cam for sure.

here we go again......

I am very happy with my inexpensive street performance 318 combination, h
Here it is: 318 bored .030 over, stock crank, rods, flat top pistons, trued up deck and trued up Magnum heads giving me a legit 9.0 :1 compression. Cam is 212/220 at .050, .480/.512 lift on 110 lobe separation. Stock electronic ignition curved for a 360 by @halifaxhops. Edelbrock Performer air gap intake and a Edelbrock 1405 carb. Street stall max torque converter from A and A. Rebuilt 904 with stage 1 shift kit. 3.23 sure grip rear end.

This pulls my 67 4 door Dart plenty for me on the street. I imagine it runs low 14s or high 13s. It's just fun, it works, sounds cool and not crazy which is what the OP wants.

 

[CLAY72dart]

Yes you have to think how everything interreacts, so it's a process of figuring out what your generally gonna need and keep going over the plan refining it till you have a solid plan and even after it's built you probably gonna have to refine it some more to dial it in how you exactly want it , I'm pretty sure he's just saying don't pick a random cam and try to make the rest of the car match it.

To me you first figure out where your not willing to compromise, like gearing, stall, cid etc.. then try to design for/around that. Example, If you must run 2.76:1 2,000 stall and like to keep NA 318 and want to do 11's something got to give, like NA and or cid and or 11's.

I have a ford 9in rear that’s 3.5:1 and I want a na 318 in just looking for a good performance motor from a roll I would like to keep the stock converter and the 904 trans I have I can add a shift kit if necessary I just didn’t do that when I built it the first time. I’m just looking for a good reliable performance motor. Nothing crazy I would like to use my 4 barrel intake and a 750
CFM carb obviously I can rejet it if necessary. I want the 318 but I don’t have to have 318 heads I want to keep the rotating assembly but will change piston heads. If that puts it in perspective.

I’m thinking selling my 360 heads might be my best option here as far as compression goes I don’t know the difference between magnum heads but I would be willing to look into it. I wrote another reply about what I’m looking for and it’s good to hear other builds. Do you think the shift kit made a lot of difference?

Here is everything mopar I have.
I have a 750 edelbrock carb
750 Holley x2
China 4 barrel intake
360 stopped block
360 heads 1/2 stripped
Running stock 318
273 motor and heads
Msd distributor
Msd box x2
3 904 transmissions
One 904 is rebuilt and has the red eagle clutches
Ford 9in rear at 3.5:1 ratio
Stock 7.25 rear the shitty little thing
I have a entire disc brake kit
I have a 70 swinger and a 72 dart custom
Custom is the parts car for the swinger
I have that huge cam kit
With some rods for the adjustable heads
I have a full exhaust I got made at a shop that connects to the little hugger headers
I have 3 sets of stock manifolds
I have other little stuff but it doesn’t play into the conversation.

Changing to magnum heads is a little complicated because they oil differently than LA heads. You can stay with your 360 heads and probably see similar results to mine with a similar cam, good intake, and carb. The stage 1 shift kit was well worth the low money investment, it gives a shift that means business but doesn't give you whiplash.
