Default New Truck Guy Looking for Advice on 318 Rebuild

SO, I'm the proud owner of a brand new (to me) 1974 D100 w/ a 318. I'm looking to rebuild the engine so I can get more years out of a truck that I payed $700 for. I would like to up my hp from the stock 150hp to the 200-300hp range just for better daily driver capability, but I am much more concerned about being able to drive this truck for years to come. I have plenty of time for the rebuild (6 month before I will need to drive again), and I am looking to stay under $1000 total. Any advice would be GREATLY appreciated. Any and all questions are welcome if more info is needed. Thanks!

i don't know if you will get 300hp out of a 318 for under $1000 but you may be able to hit 200hp. i think one of the biggest mistakes people make with trucks is that they over carburate them. for a 318 in a truck you really don't need anything bigger than 400cfm carb. trucks make all there power down low. by the time my 81 hits 3400rpm i am doing nearly 90mph.

Yea the hp boost is really lower on the list compared to running right and longevity. I really only want a little more to make driving around town a bit better.

what carb does it currently have on it? if it has a holley carb you may just need something like a tow/rv cam tossed in on a stock rebuild. could also do a compression test to see what shape the engine is in. this may allow you to save some money and just toss a cam and new valve seals in the engine. i know i was quite surprise when i got about 150-170psi of compression out of my 81.

I really dont want to do an engine swap, I would rather just rebuild what I got. The carb is the stock carter.

After more digging I found a have a model BBD Carter, which had varying cmf depending on more specific model numbers. At most I'm getting 365cfm. Would replacing this with a Holley be a good investment? Im going to stick under 500cfm, so would a 2 or 4 barrel be best?

if it works good you could try keeping it. i just know some of those carter BBD carbs don't work that great compared to the holley 2 barrel that was also used on a lot of dodge's. if you get the right 4 barrel and set it up right it can get you good gas mileage if you can keep your foot off the gas and it would also get some good power. the 2 barrels usually will get you decent gas mileage even if you have lead foot and also allow for good off the line power.

2 barrels would be easier to find and work with. I think a 4 barrel could be nice if it was a style like the Carter Theroquad, tiny primaries and HUGE secondaries.

Plus the 4 barrels just sound awesome.

So this is my plan so far:
Headers (3" collector)
Aluminum intake
New 2 barrel carb
Everything else cleaned and freshened up

With this plan in mind, would a different cam other than the stock cam be advised? Im trying to get a little more hp just because I feel like I really have to get on the gas just to get the truck to move, which could also be just because it runs a little rough now. Not sure....

there is no point sticking an aluminum intake on it especially if you plan on just sticking a 2 barrel carb on it. you are better off to just clean and paint the stock intake. stick a rv/towing cam in it and you would probably get a bit more of what you want. they give great torque off the line and also offer good power up high. i know i wouldn't mind sticking the summit 6900 cam in my truck if i had the money to do it.

Oops I didnt mean the 2 barrel, I meant 4 barrel. I've been looking at the Holley Model 4160:

Gives me a small 4 barrel without too much sacrifice to mileage.

I would get that cam Crazy has a link to, and a Carter or Edlebrock carb, and do an aluminum intake. Stick with a carb in the 390cfm though.

when you work on the carter BBD it has two screws that go throu the top casting all the way down to the bottom casting. be sure to NOT over tighten them that will warp the castings. make them just tight enough.

They take it great, as long as you dont go crazy on CFM's. I have been running a 5.2 Magnum with an Edelbrock 4 bbl for about two years. Only reason I did that though, was because it was alot easier, faster, and cheaper to carb the Magnum that I dropped in my '78. Now that I have time and patience, it is getting replaced with a 5.9 and Fuel Injection.

Well, that's cool. I didn't realize you were running a carbed Magnum. I thought it was an LA 318.

Cool beans dude.

When are you going to get us more pictures though?

I just found this. 280 horses and 340ft/lbs sounds nice.

Here is the parts list, but with different headers

http://www.summitracing.com/parts/cc...iew/make/dodge
http://www.summitracing.com/parts/bi...el/d100-pickup
http://www.summitracing.com/parts/dcc-4876334/overview/
http://www.summitracing.com/parts/dem-1282010

If my offhand math is right, its about $1300 for this setup, but I'd say you could probably sub out some parts to get that down some.
