would like info on a 351 in to my car i've heard that the shock towers need to be cut . were and how much ? headers will my 302 headers fit? would like to know before i paint and buy the 351.
need to move inner edge of towers outward as much as possible and as low as the upper a arm bolts allow. do search on here and get pictures. the headers - how close to the floor are they now? they will move up about 1 1/4" & outward about the same. if you are putting a victor jr on the 351 you night have clearance problems.
What 351 are you thinking of? There were a few different 'flavors' of 351 over the years. Tower shaving is not a must, however it can make life easier. 302 headers will bolt to a 351w head, but will not work when in the car. I have heard of folks using the 302 headers as a base for custom mods to make them fit. Several companies make, sell, or market different swap headers for the 351w or 351c. I had a C in my 75 without shaved towers. If I did it again, I would shave the towers. Dave
I had one w/351w & stock exhaust manifolds.No cutting was done on the car....but there should have.Plug changes were impossible w/o unbolting the engine and jacking it up in the engine bay.
i had a 351w in my car. if i had to do it over again i would shave the shock towers. also the 302 and 351 headers are different even though they will bolt up to the heads. you'll probably be better off buying headers for a 351w in a maverick. try a search in the archives. there's been lots of discussions about these before. jmo but if your going to do a fairly stock 351w you'd be better off with a 302 stroked to 331 or 347.
Damn Jeff, you just missed it. I spent last Saturday over a buddy's shop shaving his shock towers for a 351 swap in his 74 Mav. I took pictures and will write a tech article probably sometime this weekend.
i'm in the process of putting a 351w in my car. i'm planing on eventualy putting in a mustang II front suspension so i didn't have a probleam taking a hamer to the shock towers. i just smashed them in too make enough room for the 351w.
how fast (et) do you want to go? you can put a stroker kit in a 302 block (331, 347) and a good head and make 500hp and put the car in 10's, if you are looking for 9's, then I would say have it, but if not, a 351 isn't the only option to make power. Duane
if you get one made for a Maverick (Rod N Custom) no problems at all...RC-107...do a search, plenty of reading.
