TTI headers/exhaust
« on: October 26, 2008, 02:01:05 PM »

After browsing various sites for headers + exhaust systems, TTI seems to be the overall best for the headers.

http://www.ttiexhaust.com/Exhaust_Systems/2.5H.htm

2.5" should be plenty for a 318


They even have the Torque Shaft Assemblies for the driver's side header

Anybody have any other suggestions or ever used these guys?

Headers are a waste of time on a 318. . .Just get a dual exhaust made for it.  See your other thread.

Will the stock 318 manifolds fit with 360 heads?

Yes they will.
Even better is if you can grab a set of Magnum logs off a Dakota  91 or 1992.
I agree that headers are a waste of time and money on the big C 318.You need bottom end grunt to move that heavy slab and headers will hurt your torque.
Depending on what year of 360 heads you get,anything 1976 and newer will have smog holes under the exhaust ports.Be sure to either match up the logs or tap and plug them thar holes.
Be sure to plane the 360 heads as they will drop your compression if not done so. 
As for exhaust,2-1/4" pipe is more than plenty on a stock or mild 318.
2.5" is louder  and again you will lose more bottom end grunt.
 
I did a 71 Coronet with duals in its 318,factory logs and 2-1/4".That thing surprised a lot of people!!

The maggy manifolds you need are the 92/93 but teh later ones will work too...just the exit opening in the manifold os a bit smaller.   If you go this route you will need to upgrade to a cable kickdown since the rod style will hit the manifold bolting flange.

Also any smog 360 head will outflow a stock 318 head...planing them is good advice too.
 
And I agree on the 2 1/4 pipes...a 318 will bog out with anything bigger.

There are other things to consider as well with the magnum head swap.  Oiling the calves.  The rockers are oiled by the push rods.  You'll need to use AMC push rods.

Stay with the 360 Plan.  I have the smog heads. . .  They need to be done over.  My guy can do them for 200

Yes indeed Steve,I forgot about those 302 heads!! Closed combustion chambers for better quench and flow.
Mike grab aset of late model 302 318 heads off a Diplomat or 5TH Ave.Dirt cheap to buy as cores and cheap to rebuild.Designed to run on the corn swill we call gas.
Those and the Magnum exhaust logs will be perfect for Big Mikes Big Green.
When Big Mike,Mobby and P are cruising it it you can call the big Plymouth

I disagree guys...those 302 will bump up his compression too high and do not flow anywere near a well as the 360 smogger heads.   He'll have to buy a higher octane gas and have less power and flow...so I suggest going with a good set of smogger 360 heads for the best bang for the buck.
 
Also those 302 are very prone to cracking.
