6 pack pro's vs. con's

as some of ya know i was given an old 79 dodge truck which will become my new work truck when i put it back toghether.

anyway i was looking for a new 2bbl carb at this shop i go to down the road and the guy in there has a couple 6 pack set-up's in there (intake and carbs) anyway he says we could work something out for a set-up, but if i put one of those 6 pack sets on top of my 318 will it eat ALOT more gas or just a little more vs. a 2bbl?

do you think the extra hp it would make would be worth the extra gas it'll burn? or should i just stick to my OEM 2bbl?

carbs & mopar is new to me. i'm more of a EFI chevy man

Unless you have a very serious engine, 3 dueces will be over kill. Most six packs are set up to run off the center carb up to about 1/2 throttle, then any more pedal and they all go wide open. Its easy to drown an engine with that much carb. They look cool, but are not very effecient.
Buddy of mine had 3 twos on his Ram Air IIII Judge way back when. Engine was built to the hills, 4 speed and 5.13 gears. Pretty much untouchable from zero to 50!! LOL But a well tuned 4bbl did better.

When my dad and his cousin ( my second cousin ) both had Mopars, my dad had a 383 w 440 heads/ 4bbl/ auto in a '68 Cornet, his cousin had a '69 Road runner with the 440 6 pack/auto, which would stomp all over my dads '68 when he had the carbs tuned in, and they always needed tuned. If it is a DD than go 2bbl but if your gonna rod it, go ahead and keep the carbs tuned.

well i don't wanna keep tuning it, but i thaught it would look cool to have a 6 pack on my work truck so everytime i opened it i'd see this http://cgi.ebay.com/ebaymotors/mopar...spagenameZWDVW

you think i could get more power w/a 4bbl with about the same mpg as a 2bbl?

I have done a couple of 318's with the RV type cam, headers, dual plane intake and a 1850 holley. The power definately jumps, and once you finally get used to the power, the mileage also went up 10 to 15%.

If you have dual exhaust now, get a dual plane intake and a 4bbl with vacuum secondaries. It will get 2bbl mileage and 4bbl power when needed.
