Ok i will tell yo what i know of the 351 W and how we use to set them up back in the day . I use to work in a large Ford dealership and we were heavily involved in in the Drag Club i was the so called expert as i was the performance adviser and head wrench . So first off for get the retard as that was the first things that went to the dumpster now as to curb timing this all depending on if it was a automatic or a four gear , on a four gear timing was set a 10 degrees BTDC and a slush box at 5-8 BTDC. total full advance was 38 degrees at 1800 on the four gears and and 36 degrees at 2000 for the auto. ( now keep in mind here first we were working with 10.5 to 1 compression C /Ced heads and most all the 351 W's in the club were now sporting the C9OZ 6250 C cam that was made for the 221-302 and just by swapping firing order you could run that cam. We were running Holley 650 vac secondary with staggered jetting On the four spped cars were were running 298 dual point dist. and signal points on the automatic . Now please don't ask me how i curved the dist. for each as it has been 49 years ago and i made the mistake of letting a friend BORROW my notes and all my tech books as he was working on his 65 Mustang with a 289 271 . and one night out with the GUYS they were involved in a wreck and he died . I neve saw my big thick black binder again and it had a trove of info and part numbers and phone numbers . Now what i do know today is with what is out there for PUMP gas your not going to doing the 10.5 to 1 compression thing and your not going to be hitting them 36=38 degree full advance . Last i talked with OLD friends who were still playen they were having a hard time at 9.5 and 34 degrees with the 93 pump gas even on the street. Ah for the good old days
