Changeing a 302w to a 351w - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

HI guys/gals Imjust wanting to know If it is a simple matter of changeing the crank rods and pistons of my (69) 302w to 351w ones to change the displacement to 351. As I have been looking for a 351w for my fairlane and I have not been able to locate one so I thought that this would be the easyist way to do this. I have looked at strokeing it but at best it only gives 347cid and the cost is prohibitive, so If anybody can help me out or point me in the right direction I would appriciate it!
Oh by the way the car is a 1969 ZC fairlane 302w+C4

Keep searching!

The 351 is the cheapest way to go by far. Have you considered a Cleveland? They are much easier to come by.

302w and 351w blocks are different, 351w has a taller deck height.
IMO a 351w will be a little better than a 302w stroked to 347 as the rod angle will be better.
The 347 is pretty good though.

If it were me I'd throw a Clevo in it....

Have a look at some mustang parts importers and engine importers for a 351w... If you are after a 351 clevo, there are plenty around, and at reasonable prices.

Umm clevo shiteloads heavy compared to 02/51 windsor, 429-460 only bout 100Lb heavier, less w alloy intake, similar mods to clevo 500HP/ftlb easy 5500-6000rpm. Small windsor goes like clappers (seen many a clevo go under) w basic mods (heads dear part). If want the ultimate, use svo 351W type block (small main) stroke to 400+ use good heads big solid roller etc etc (hope u got deep pockets) and eat RAT's for breakfast while weighing in slim!

Clevo is only marginally heavier than 351w.

As i have a 347, i would strongly suggest a 351 windsor or clevo
You can stroke them and get far more power for the same money.
That being said my 347 goes ok.........its just a power for money decision

Thanks for the help guys Is it true that all of the aust 351w came with 4v heads? Or did all of the 351w come with 4v heads. and can you but gt40p heads on a 351w block and is it worth it as I found a 351w short and I still havent been able to find a set of heads for it. and is 500 + postage good for a used short?

All 351's pre bout pre 76 or 74 came with same heads (maybe small chamber size variations) then went to same huge chamber small valve heads as 302's. Common misconception is (American) 69 351w came with 4brrl heads but only diff to get the compression to 10.7 was a set of f top pistons ( i have a set inside a 69 4bbrl 351 from 69 convertable stang which was the only year ftop pistons for 351 offered from factory!) as always there are always exceptions to the rules like chamber sizes offered per year etc etc, but main thing like port volume's same
