underdrive pulleys
Has anyone ever thought to cross reference the 4.9L pulley P/N's to the 5.0L or 5.8L's? I know that in the 60's the 200 and 240 shared the same pully's as the 289 and 302. Not sure if anything has changed though. Maybe I'll just have to call a couple Ford Dealers today *grin* (I love making the parts guys pull their hair out).

Ok, how did you get them to give you a pulley number when all I get is chip, filter, thermo, and package parts? Share the wealth....what's the PN????

[font size="1" color="#FF0000"]LAST EDITED ON 03-Mar-01 AT 02:16 AM (EST)[/font][p]Ya know, theoretically all you need is a pulley that is A) in line with the rest, B) bolts up, and C) underdrives the accesories (smaller on the crank, bigger on the accesories). You will have to do some sould searching for the right belt (even I had to with my March pulley kit for the 302)
but that's all the set really is. I know it's back yard engineering, but that's where it all starts. traildawg has got the right idea...
just remember to keep track of your ratios.
1989 F-150 : 5.0, shorty headers, Flowmaster cat-back, K&N filtercharger intake, March pulleys, "Multi-brand" performance ignition, soon to be Mass-Air...doesn't know she's not a Mustang

[font size="1" color="#FF0000"]LAST EDITED ON 03-Mar-01 AT 03:53 PM (EST)[/font][p]hehe.......guess what paul, that's the 302/351 P/N. I just went back and nada for the 300, so I checked to 351 and 302 and there was your P/N 90103. You musta prematurely clicked. LOL Back to the drawing boards.
Oh yeah.....I'll be waiting for the famous Homer Simpson "DOH!!!!!!!!!" :P
