Looking to build up a 351W for now, basically get as many ponnies as possible but still keep it steet worthey and practical (not talking about gas http://3wheelerworldforums.com/images/smilies/lol.gif ). Anyway I was originally gonna go for a classic mustang, but then I realized that it's a pain to find rollers in decent shape and standard transmission!!! So now I figure a fox body is the way to go. Plus I wouldn't feel as bad about having to put a roll cage in one and do any hacking/welding that may become necassary. I could build up a 302, but since the prices for stuff is all the same for a 351W I figure I mine as well give myself the displacement if I'm going to do the work....

Basically my question is this: Will a 351 windsor slide in easily to a 5.0 fox body mustang? If so what years???

and if I do have to force the engine in, what work will need to be done?

P.S. Sorry administrators that I posted this on the drag racing forum too, I'm trying to figure out how to delete it on these forums....

well since the 351 and 302 are based on the same block, it will be a piece of cake. i think the only diff. is that the 351 is an inch taller(??correct me if i'm wrong). but everything you will need is available just about anywhere. meaning headers, oil pan/pick-up, motor mounts, stuff like that (headers are 351 specific, i know that for sure). some companies even offer everything in a kit form check out holcomb motorsport's, mustang's unlimited, summit, jeg's, look around you'll find everything you need.
i think the only clearance prob you may have is hood clearance but that's nothing a cowl hood wont handle. other than that installing the motor will be the same as if you are doing a 302.

I am in the middle of swapping in a 393, which is a stroked 351, into my '85 Mustang GT. As far as fit goes, the only problem area is that the motor is taller and wider, but a cowl hood will take care of that. The use of dropped motor mounts and careful selection of intakes allows some people to fit them under a stock hood, but it's pretty tight.

Parts that are different between the 302 and 351 include:

flywheel and balancer, due to different balance, 28 oz instead of 50

oil pan

intake manifold, because engine is wider

distributor, needs longer shaft

headers, will need swap headers to clear k-member and match up with exhaust pipe location.

I think that's all that has to be changed. Although they will fit, you most likely won't want to use the heads and cam from a 302 on a 351, as you won't get the full benefit of the larger engine.

will a 5.0 5speed trans bolt directly up to a 351w,if not what will I have to get to do this?

I used the transmission and bell housing from my 5.0 when I swapped in the 393 so I don't see any problem there.
