Nope, it was discontinued long before there were electronic engine controls.

Nope. 1999 was the last year of the 350 in the Tahoe, with 255/335. 2000 was the first year of the 4.8 and 5.3.

 

Lol haha what if i said the manuel says its 350 and the numbers on the block too

 

That's what I'm saying, it has a 350.

 

Wel, this was a fun read. Heh.

 

Then I will call myself corrected lol. Silverados last year was 98 for the 350. I assumed tahoe was too since it was usually same chassis as silverado. My bad lol

 

Yup 255hp 330lb-ft and 5.7L
Silverado in 99 was 4.8L V8 255hp 285lb-ft. ...5.3L V8 is 270hp 315lb-ft then they were both bumped up over the years I believe to 305hp in the 4.8 and 335hp in the 5.3.

 

He meant my part. I stand corrected.

 

on the 89 302.

dont know if still avaialbe but on the do it your self thing with simple tools .

smaller crank pulley, cold air kit, hypetech chip, electric fans,

maybe set of 1.6 roller rockers

then maybe headers and upgraded exhaust

the 302 heads where terrible...all of them. an aftermarket head or a set of the gt-40 iron heads would be a giant improvement if they will work with the current piston.

 

I guess I should have gone into details about the 460 conversion. You're looking for a mid 90s F250/350 truck with the EFI 460. You want the engine complete with all brackets for alternator, Power steering, etc you want the transmission, you want all of the electronics including those in the exhaust headers, you want the exhaust headers, you want the motor mounts all the way to the frame, you want the radiator, fan shroud and all transmission cooling lines. You want the wiring harness and the PCM. Now that you have everything, it's an almost a bolt in your truck conversion. You need the driveshaft too. Once you have the engine in and transmission, run all of the electronic wiring. Make sure you have an in tank fuel pump or you'll need to add one that is capable of minimum 40lbs but I think yours is already equipped with one. Hook up the transmission module, set the radiator, bolt everything up. The only place you'll need to custom or fabricate anything is the driveshaft and since you have the original and the 460, it's a matter of cutting and welding at any welding shop. You'll spend about the same money on this as attempting to get any power out of that 302. Put in 26lb injectors and expect to buy rear tires often....REAL OFTEN! Yeah, I did this conversion years back to a buds 91 F150. It was so good and tire costs so high his wife said to park it or sell it. He sold it. I've been contemplating doing this change over to my Bronco as I helped with one of those a decade ago. The A4OD CAN be made to be pretty bulletproof but like anything else, it just takes money.

 

It might be cheaper, easier, and less confusing to just find one with a 460 and buy it tho.

 

You aren't going to find a F-150 with a factory 460. It was only in the F-250 and bigger. It's also a huge gas hog.

 

I meant just a truck in general....figured not in f150. Was suggesting buying a truck with a 460 instead of a swap and selling the f150. Was on break at work so I was thinking more than I could write in that time frame. Lol

Either way an 89 V8 will be a gas hog, just depends on how big that hog is. 89 302 you would be lucky to see 14mpgs. A 460 lucky to see 10. I'd say realistically 10 to 12 in a 302 and probably 7 to 9 with a 460. I had a 78 351W f150 2wd 4spd manual and got 10....also had a 305ci 86 chevy custom 10 2wd 3 spd auto....also got 10. Both were reg cab longbed.

 

"keeeping it real"

chevy had the 454 ss which was similar power as a mid 90's 460.
it was 9 to 11 mpg and ran mid 15's in a shortbed single cab truck, a new ecoboost or 5.0 would smoke it.

ford had the 351 lightning, gt40 heads, intake single cab, short bed...mid to low 15's

finding a good shape, mid 90's f250 for a reasonable cost...good luck. back in mid 90s guys that bought f250 actually needed and used them, it wasnt a status symbol.

i do like the ides that a younger guy with limited funds and not a lot of experience starts tinkering with an older vehicle. great learning - life experience and making something a little better is a great feeling. i have to add that for every major project that gets started likea complete engine swap, rairly ever get finished.

 

I owned a 94 F150 swb 4x4 with the 302, auto, and 31x10.5x15 tires. I bought it with 35k miles and traded it with 92k miles. I did not feel like it was underpowered. I thought it performed acceptably. The 2000 f150 scab 5.4L 4x4 I traded it in on was more powerful of course.
The 302 is a short stroke engine giving it less low end torque and lower fuel economy, so it isn't an ideal truck engine.

 

Yeah 454ss was like 7.4 to 60. Not bad at all for a truck. Mid 15s sounds about right. You would be better off modding the 302 I would think. Swapping engines and then upgrading would be a job and a half....on the plus side the engine is out for upgrading... and like it was said above...those f150s were used for what they did so a 460 that hasn't been thru a lot would be a hard find.
