Just a line to say hello. I'm fasteddie. I love my 1978 Ford F150 truck. I want to pick up some good info to use on the F150. I see a motor and transmission swap coming.

I have a 1977 F-150 with a 351m, is it possible to take off the EGR under the two barrel and install a different dist. I am looking for better performance and mileage on a limited budget. Thank you for your replys.

If you remove the EGR, you might want to just retard the ignition a bit. Kepp your stock distributor...just get a brass cap and rotor. Something like a Davis distributor is gonna set you back $300+... for what you are after, a Performer type intake, headers and a 500-600 cfm carb would yield you the most bang for the buck...someone else might chime in as well...

I suppose it would.

I may be wrong but it was allways explained to me that the M attatched to the 351 stood for modified Cleveland...

That's been the generally accepted idea, but there seems to be no actual documentation on it.

Since 'M' is exactly half-way in between 'C' and 'W', I think it stands for MIDDLE??????????

No. 351M wasn't introduced in the truck line until 1977.
