Before I would look into a chip, I think stubby headers and duals would work wonders. I sure have slight pinging under load using 87 gasoline which might be a hint of a chip? The Mustang's started using a roller cam in '88 models,but trucks used a flat tappet cam with the same Mustang roller block thru 1991 models. The 351 was rated at 200 in 1993,but 1988 through 1992 were rated at ,800. This type of indirect fuel injection places the injectors in the engine's intake ports instead of directly into the combustion chambers. Brand new dual magnaflow exhaust, straight back, with chrome tips.
That would lead me to believe '92 was the first year for the roller cam in 302 truck engines. Another good source for info is F. I have so much stuff, it's literally all over the place. That's interesting about the 87 302, Ford did some updating in 1987 over the 85 and 86 models. Maybe a few truck engines got them??????? Part of the rating is due to the roller cam change in early 1992. The Ford 302 was a Windsor small-block, 90-degree, V8 engine. The 1992 Ford 302 engine uses electronic sequential port fuel injection.
There's nothing like talking about engines-n-stuff. Thanks again for the input! Both fuel injected and carbureted 302s have two valves per cylinder head. Since the truck engine was transplanted by someone else, I don't know if they had the time for some performance mods, e. If you are asking about a car or truck you own, try reading your owner's manual. Guess thats where the 10hp came from? As for your '93 engine having a roller cam. I get a lot of stuff from Ford, and I could've sworn that with the info. There is no way to answer this question without more information, i.
I can say however that there are some ratings changes from 1991 to 1992. There was no ratings in the regular non-commercial brochures for either year. I can't dispute his claim. We liked the engine then,and we like it now. I have both the 1992 and 1993 ford tech books and they both state 195hp. Short wheel base, no rust in bed.
Right now the truck has manifolds what year I don't know and single cat into single exhaust. Ford has a 1-800 hotline which they can answer questions like horsepower ratings,and the like. Same thing is said in wife's 97 F-150 manual about the 4. In the 1990 book it states:315 lb. It was developed in 1968 from the Ford 289 by shortening its connecting rods for a 3. Several members here have claimed that late 1992 was the change-over year, I can't say for certain I know.
I will post again if the chip question bugs me. One book that's a non-Ford source book and a great book for info. The brochures don't state numbers either. The Ford 302 first featured indirect throttle body fuel injection in its Lincoln luxury car application for the early 1980s models. Hopefully, they'll get back to me soon.
I've been meaning to ask about a roller cam swap for my 1990 Bronco's 5. They basically said Mustang 5. You need to be more specific if you expect an answer. I believe the 1995 and 1996 F-150 302 cubic inch 5. I will try a tank or two of 92 octane and see if it still does the pinging.
Sounds great in person, will have a much better video, on my camera, when the weather clears. The original owner claims our Flareside has a factory roller cam,and driving the truck the few times I've had wheeltime. I also have many Ford factory publications not just brochures ,and many magazine articles of roadtests of new Fords. Ford Focus, Ranger, F-150 -- they are all different. It used to do it.
I think it is time for a G-tech after all? I'm not trying to say whose numbers are right,or whose are wrong,I'm just going by Ford's numbers. When in doubt, I figure they are the best source. This book not only lists engine specs,but also stuff like production numbers, factory prices for options,and shipping weights. . Very clean, just a little bit of bubble rust around wheel well. They obviously got the 185 horsepower number from the '87 press kit. Now, I guess my truck isn't that heavy either though.
Please dont judge the truck by the bad video. My Factory tech book says both the 302 and 351s were roller cams and a very few california 302s had mass air in 1993. The thin-wall block engine uses high-flow aluminum cylinder heads. This is the fully loaded xlt package. I am legal to do whatever I want, of course, since it is a 70 model, here in California. Look through the book, you'll see '92 front clips on 1991 trucks. New plugs, wires, hoses look new.
