Which one is best as far as towing, and fuel mileage? I'll only be towing a couple thousand pounds.
i own a 4.6 and drive a 4.9 pretty often and i prefer the 4.9 seems to have alot more power and i think the fuel mileage is a little bit better but i could be wrong. I only get 12-14mpg with the 4.6
Both are good but the 4.9 is argurably the best motor ford makes. The 4.6 That we have is very picky about oil it only likes castrol 5w-20 but is running strong after 160000 miles the truck is falling apart though.
4.9 or 300-6 had been in production for 30 years of ford history, it is diesel gasser, most of them last 300-400k before even overhaul. It tows better than newer 4.6 for sure.
I think I would pick a 4.9. I really wish that engine was still an option. Hard to belive the last year for a 4.9 was 1996.
I agree, that is a great engine! I also wish I could still get a new truck with that engine as an option.
The 300 cid I6 is the best motor Ford ever made, and it's not even close. They are like the slant 6 Mopars. If there is ever a nuclear war, the only thing left will be mutant cockroaches driving slant 6 Dodges and Ford pickups with the 6 cyl.
I've never heard anyone complain about the 300 I-6 engine so popular in Ford trucks. As a general rule, most inline engines offer more torque as well.
And those that do are somewhat uninformed.
The 4.9L six like other guys have said has good low end torque, but the 4.6 V8 is a much more modern engine and depending on year will have 60-90 more horsepower than the old 4.9 and better performance in daily driving. I have driven many Ford vans with both the 4.9 six and 4.6 V8 and the 4.6 has much better acceleration. Nothing wrong at all with the 4.9L six though.
