If you don't want to drive it everyday, They make a 434 stoker kit for your block. That would be a good start, with a 292 or a 305 cam. A street domanter intake, a set of allumuin heads. Headers and 3" pipe. Is it going to be standerd or auto?
I Know, the bronco currently has no motor in it. I'm doing a complete rebuild of it. New drive train new suspension new interior, and paint.The 351m was given to me by a good friend. The bronco original came with a 302 mated to an AOD. thanks for all the info tho.
Personally I'd start with a 400 crank, add some zero deck flat top pistons milled to about 10:1 C.R., a pair of CHI 3V heads, a 280-290 dur. 530-550" lift cam and a good mainfold/carb combo. That should put you somewhere in the neighborhood of 450 HP but it's probably going to be fairly high up in the RPM range.
Personally I wouldn't try, and put a 335 series engine in that bronco, getting things like headers to fit is a pain, adds a lot of weight (although with the alum heads this will be negated mostly) and generally isn't a good swap since the aftermarket really hasn't done a good job on supporting the 351m/400s although it is getting better. a 351w with a stroker kit, and aftermarket heads properly built would be a much easier, and in the long run cheaper alternative,
I can't believe I didn't just suggest a bbf, but for the trouble, and weight considerations that your looking at it would be a better choice to swap in.
I somewhat agree with da monster but am planning to put a 400 into an 83 with a W in it as I think I am becomming a fan of the 400 cleveland...thats right...I call it a cleveland because mine is a '70 and that, in reality is what they are once built right. I also have an extra c-6 (385) which helps in the swap.
I am only relating from what i have read and learned and owned- most here are the ones I've been learning from and thus know more than I. I am building my 1st 400 and suspect that a low-end torque build is the best solution as it will give you great torque, very respectable hp, the best possible mileage and longevity. If you want it to scream, guzzel and fizz the builds above would probably be best.
I have done this swap for the last 4 years iv been building it. My 400 is in a 1994 ford f-150. If i where to do it all over agian i would have picked a 302 or 351 and stroked it for the amont of time and money i have into mines i could have had more horse and torq then my 400. Now im not baggin on my 400 project im very happy with it its just been pain for example. i have 351c heads well i ordered up a set of 351c headers for it and 351c only came in cars so i have car headers which is ok in a 2 wheel drive but in a 4 wheel drive it lands right in the way of the front driveshaft so you either have to custom make some headers or figure out the way around that. it isnt impossible its just not a dump in and go fix where as a 302 or 351w came in broncos so its pretty easy to find parts. Its just hard to find parts for the m or older truck parts just my 2 cents
