really off topic, for you gearheads

ok, absolutly nothing to do with archery here, but i know that about half of yall are mechanics in some way shape or form, so i figured id ask you for your oppinion. ok my truck is an 89 dodge ram d150. it has a 318, (5.2 L), carburated, i cant find an exact number on the horses but according to google its between 140 and 170 and its in decent shape. i got a tranny problem right now thats priority to get fixed. it works fine in drive, but dont like reverse. idk whats up with that. but anyway after i get that fixed i want to start playing around with the motor some. im thinking start off with a new edelbrock intake manifold and either a four barrel or three duces? im pretty limited with my tools, so i cant really take out the motor to change cams or anything like that, i just got to play around with what i can with bolt on stuff. its not much to start with, especially just working with that little 318, but i got nuthin better to do. do you guys think i can get any performance out of this old thing with enough work?
Yeah i know im an idiot, but hey im seventeen, whadaya expect. ::) ;D

well speaking in great honesty as i have quite a bit of mechanic experience with drag cars as well as 4x4's. Especially with a truck, your not going to get a noticeable amount of power from bolt on's. infact when i vehicle is designed from the factory it is designed to have efficiency and suitable power, when you add a new intake\carb, that may help a bit but probably be about 8-15 hp. tops notvery uch gain for the cost. you will most likely dump lots more fuel and have very limited gains. 3 dueces is a poor choice for a truck, they are meant to dump air and fuel all at once. you will overload the engine and destroy any gas mileage. just remember, a big carb and manifold may provide more air and fuel but if its backed up by stock cam, valves, compression and exhaust you can actually lose power along with mileage. and when you have an older truck with high miles and it still runs sound, its b\c it has worn and aged together, if you add new performance parts you are often times asking for trouble.....but if your anything like i was at 16 or 17 your gonna do it anyways..cant really blame you, thats how i learned...lol so for an intake you want a very mild low rise dual plane. edelbrock performer intake manifold, idle to 5500rpm. i wouldnt go any larger and definitely stay away from single plane intakes. and get a holley carb no bigger than 600cfm but 500 or 550cfm would be better. mechanical secondaries are easier to work on but will waste fuel in a truck (4150 series) i would suggest a standard holley 4160 series with vacuum secondaries. and when you adjust the secondaries to open, read the manual very carefully, most ppl want the secondaries to open fully all at once like a mechanical carb....but they are not meant to...remember its not a race car. i have the same combo on my 85 bronco with a 302 along with shorty headers. not a powerplant but it does what i need it to. only reason i even put a edelbrock intake and a carb on it was b\c it was cheaper than buying oem parts...lol true story.

I agree with most of what T.L. said you may find that a really good tune up will surprise you I have owned a few Dodges with that setup and they can be really hard to get tuned properly.JMHO. Ronnie
recurve shooter:
lol well i figured something like that was comeing. ;D i guess i'll just go with a good tune up, new tires and shocks, and maby go pull a motor off of somethin in a junk yard and set it up in the shop and start rebuilding it. ??? man this is gunna be a longer, more expensive process than i thought, lol. ;D
thanks guys.
Ryan_Gill_HuntPrimitive:
sounds like you got a good idea. keep your good truck for normal use, just tune her up. if you want a offroad truck get another one and rebuild the engine for more torque, that way your daily driver isnt down when you start busting driveshafts and axles. oooohhhhh yeah, you know it gets more expensive. a great drag car builder told me long time ago, the faster you wanna go the more money you drop, but each horsepower gets more and more expensive until your paying $1000 per 10 horsepower. and it really does!!. for example. my old mustang i built. i had a .585 lift hydraulic cam but only 9:1 compression and a 1500 stall converter and i wasnt smart enough to realized that just 1 high performance part on a low performance engine will hurt worse than no high per. parts at all. they all have to work together and be matched to one another when i finally got the car together the way it needed to be i had a 351 cleveland w/ 11:1 compression, .612 lift solid roller cam, 2.19 1.73 canted valves, 800 cfm demon carb, full length custom large tube headers, 4200 stall converter and about 12K worth of parts in between. but it also ran 11.3 seconds quarter mile all motor and 10.7's on a mild shot of nitrous, man i do miss that car...but it doesnt do me a lick of good here in Montana...and i choose mountains of mustangs in the grand scheme of things. and your never finished either if i didnt sell it i would still be buying parts.
