I have heard that trucks with 4.3L 6 cyl actually get worse gas milage than
the same truck with a 305 so just because it is a smaller engine doesn't
mean it is better on gas milage you have to remember the smaller engine
needs to work harder to move the same amount of weight (generally speaking.)
I used to have a '93 c1500 with the 4.3L in it. It got 18-19 mpg on
the interstate. I pulled my fishing boat and car trailer with it just
fine. Sure it didn't have the power of a 350, but it got the job
done. Also had 216,000 miles on it when I got rid of it, original
engine and tranny still running good. I think that if you have
somthing you can't haul with this engine, then you are asking too much
of a 1/2 ton truck in the first place.
Don't get me wrong, I love the power of a 350... Just had to defend
the good ol' 4.3L.
i got a 305 in my '89 2500 w/ 5 spd...feels like it has more balls
than my work truck which is a '90 454 in a 3500 auto, both are long
beds. could be because of the trannies, i really don't know but fully
loaded with sand, the 305 really hauls...it really impressed me
especially when i compared it to my old truck which was a '88 f150
with a 302 5 spd, short bed.
nope, had a fleet of 6 3500 c's and k's, 4 with utility beds, 2
fleetside longbeds, all 454, 4 speed auto o/d...all operated the same
(same power curve - which was somewhat lacking, brakes overheating -
especially when going downhill, drank gas like it was beer -
especially while towing, window regulator rotting away, etc.). the
ones with the utility beds were the worst performing. now we're down
to 2 - a utility bed and my longbed...i got the 2500 for free (i had
to put a little work into it) but i was kind of hesitant in taking it
because of my experiences with the 3500s but i'm glad i did...turns
out to be a pretty good pickup.
Cool to hear. I can notice the difference between the 305 in my K5
(carb) and the 350 in my Jimmy (FI) but it didn't rock my world like I
thought it would. I'd still like 4 on the floor.... just love drivng
Stick with the 350 for ALL the reasons above! And for the fact that when it
needs a rebuild it will cost 1/3
less to put the exact same stuff into a 350 compared to a 305!
| will a 305 bolt on to a 350 5 speed tranny. i love the power in my truck
| but have the gas pumps. would i notice any difference( getting 14 on a good
| day currently ) if i went to a 305. thanks. no major towing in the future
| for this truck.
STICK WITH THE 350 IN ALL ITS THE BEST ALL PURPOSE ENGINE...THE 305 IS
JUNK..UNLESS IT'S A HI-OUT PUT 1 !!!!..WORST THING ABOUT TE 305 IS THEIR
POOR HEADS ...SPARK NOCK CITY NO MATTER WATT OCTANE YOU USE
