can some one tell me the pros and cons on building a 351w vs a 302w. im lookin for around 400 hp. im not a ford guy. i know a 351 shares the same bore larger stroke and a taller deck. im sure the heads are the same? but intake must differ. thanks any insite would be most helpfull!

 

As we all know, there is no replacement for displacement. However, you can bore and stroke your 302 to a 347 to increase the displacement. In general parts aren't as readily available for the 351; they are out there, but just not as easy to get as 302 parts. You can get 400hp out of either of those engines without too much of an issue, just doesn't take as much with a larger displacement engine.

 

so you think i sould go for the 351. didnt they have like 2 diff firing orders? and what yr of block should i try to get my hands on? thanks

 

I'd go with Ford Racing's new Boss 351 engine block. As befitting a powerplant from the Blue Oval, this new block will be able to accommodate a range of classic displacements from 351 to 427 to 460 cubic inches.

Based on the architecture of the popular Windsor 351 but blessed with the more robust 2.75-inch main bearings of the old Cleveland block, Ford designed the new Boss 351 block with strength in mind through 4-bolt main caps, screw-in freeze plugs, splayed main bolts, siamese bores with engineered coolant cross-drilling, front cross-over lifter oiling, and diesel-grade iron with 41,000 psi tensile strength.

Unlike many engine blocks designed solely for racing, the new Boss 351 features a street-capable cooling design and is therefore just as suitable for vehicles intended for cruise night at the local hangout as it is for the drag strip.

A 427cid Boss 351-based crate engine producing 535 hp is now available along with others. Just depends on how much you want to spend and do yourself.

not alot ppl on this forum?

 

Most of the people come to post once or twice, but we have a hand full of us who post more regularly.

 

I am waiting until we get a new house, but I also was planning on doing a 351w build. I am going to try and find a pre 72 truck(because of CA rules on smog, I wouldn't have to worry about that with pre 76 I believe) for a project and use the 351w. I plan on going with a 351w short block and get the edelbrock top end. If this helps here are a few links I have been researching.

There are two top end kits here. #2092 400HP one is aroound $1900 and the 2090 450 HP is about $2400. (I personally will use Edelbrock because it supports local CA manufacturing, and their pricing seems competitive with others. So it shows manufacturing can be done competitively.)
