Hello All,
I am a newbie here but have owned many Dodge vehicles. I have had a 1986 dodge d100 for about 8 years now. The motor and clutch are tired. I plan to rebuild the motor but have a couple questions for anyone who cares to answer. The motor is a 318 with a 2 bbl carb. and a 4 speed standard trans. It is also 2 wheel drive. I do not want to make this a dragster! It will smoke the tires just the way it is. I was thinking of a little bit more cam, a 4 barrel manifold, 4 barrel carb and headers. What I have been reading is that a small carb would be better than a big one. Any suggestions will be greatly appreciated.
Thanks

 

The 318 is a great motor. Over looked sometimes but you can make some excellent power for minimum .

Before you do anything do a compression check on the motor. Adding power to something that has a potential problem will leave you disappointed. Make sure the cooling system is good too.

A dual plane aluminum intake manifold, a used (or new) carb in the 600 cfm range and full length headers will give it more power but more importantly more "breath". It will rev better, make a flatter torque curve, and if driven lightly wont hurt gas mileage..

 

86 I think is still the LA motor. I would go for a 600 cfm carb with electric choke for street, Dual plane intake Headers and dual exhaust, ???? dual cats ???
Some of this depends on what your states emission requirements are !!

 

Depending on the cam that you decide to go with will determine the manifold and header style that you should get. If your cam is designed to create power from idle to 5500 RPM, you want an intake that works in that same power range and a set of short tube headers. Ig you are planning on the power range being 2500-7000, then get long tube headers.

Short tube headers are great for making power in the lower RPMs, like when daily driving. Long tube headers work better for motors that make power in the mid to higher RPM range.

 

thanks for the replies...
I will rebuild the engine first, but was thinking about a mild cam and intake and carb. I have a set of long tube headers already.
Back in the day I always heard guys talking about "camper cams" I assume they were just a little hotter than stock. I will probably go that route.

 

Camper cams will build more power in the low end.

 

Our '88 318 has 600 vac holley. Ed performer and a Comp XE 256H cam. Very nice combination with nice idle, a little rummble and lots of torque. It's in our 2wd auto pick-up.
