Engine Info
I own a 93 Inline 6 4.9l and wondered what years these engines were produced . The F-150 runs great and wonder why they stopped making them . could it be they just last too long or is it some safety issue . Any opinions . These topics may have been addressed before but I am new to the board so please excuse my ignorance .

Stopped for a variety of reasons:
1) Cost. Since the 300 shared nothing with any other Ford engine, they had to maintain a separate production line. The new 4.2 is based on the 3.8 and shares parts.
2) Styling. The 300 won't fit under the extremely short hood of the "stylish" new F-150.
3) Performance. Most truck buyers don't want trucks anymore. They want cars with big trunks. The 300 doesn't meet their performance expectations.
4) Emissions. It was getting increasingly harder to meet targets with the 300 and the old Windsor SBF engines. Ford just dropped them in favor of their new and IMHO junk Romeo and Essex lines.
Hang on to your 300, they literally don't make 'em like that anymore.

Ford introduced the 300 I-6 in 1965.Starting in 1987 the 300 I-6(4.9L) got EFI. The last factory EFI4.9L engine was produced in 1996.Broncos had the 300I-6 from 1980 through the 1992 models. In 1993, the Bronco's base engine became the 302 V-8. F-150s were the last vehicles to get the 300I-6.It was the base engine for most models.

Ford still ran the 300 I6 for other uses after it was dropped from the F150. Last year I could go to the Pitt Electric site and see the 300 I6 advertized there, but sadly, I went there this year and don't see it anymore. Instead there is a V6. Too Bad. At least there are a lot of these engines around out there so they should be avail for restorations for many years to come.
Would love a Superduty (the new body style) with a 300 I6, but a 97 F250 with a 300 would be pretty cool too. In both cases I believe you still got twin-I-beam. What a blow, Ford dropping the 300 and twin-I-beam at the same time.

The only F-250 to get the EFI4.9L was the under 8,500 GVW models. The HDs...4x4 models,anyway, got a standard EFI5.8L V-8.Maybe HD 4x2 pickups got a base EFI4.9L six? I think I saw one or two. A friend of mine had a 1988 under 8,500 GVW F-250 4X4 with the EFI4.9L hooked to a granny-gear 5-speed. I think the axle ratio(s) were 4.10:1. It pulled really well for a 300cid six placed in a big pickup.We had a 1989 Bronco Custom with the 4.9L,a C-6,and 3.55:1 axle gearing.I think it needed 4.10:1s.

Hey guys, I just was looking at a 1996 Commercial Trucks brochure,and YES the F-250HD 4x2 got a standard EFI4.9L.So did the F-350.These were regular cab models(133" wb).The F-250HD 4x2 Supercab also got a standard EFI4.9L.The GCWR(4.10;1 axles&automatic tranny) were 11,000lbs. for all three of these combinations.Curiously,they list only the F-250 4x2(under 8,500 GVW) as being available with the 4.9L/5-speed...and it was limited to a 3.55:1 axle ratio.Maximum tow rating was 3,200lbs. .The F-250HD 4x2 with 4.9L&4.10s:6,200lbs.,F-350 4x2 with 4.9L&4.10s:6,300lbs., and F-250HD 4x2 Supercab with 4.9L&4.10s:6,000lbs.In one other note,I knew the 4.9L six was available in the E-150&E-250 vans,but Ford also put them into E-250HD&E-350s.Two gearing choices are listed:3.55:1,and 3.73:1.

The 300 in 6 started life as a full sized car engine as a 240 cu 6. Same motor, different head and crank. We bought a 1960 Ford Fairlane with the 240 in it. so the design is quite a bit older than the 1965 date. 1965 is the correct date for both the 240 and 300 in a truck though. If you want to get a little more compression add at 240 head to a 300. Works great. Herman
