stroker for torque

A lot of 302 and 351w based engines are built for the go fast crowd, but why couldn't a stroker be built for the big torque at low to mid rpm crowd to use in trucks where big torque is needed using the boss blocks?
The rotating assembly is worked out in most of them, you can get a short block already built from Ford and Dart (347, 363, 393, 408, 427, 454, 461). Some of these sizes anyway.
But what heads, camshafts, intake and exhaust would be best to use for torque?
A lot of the heads are for racing, I think, and the Ford boss block only takes Ford heads found in the racing catalogue. It apparently won't take production heads. Why is that? Especially confusing when these heads will fit both the boss blocks and the production blocks, but the production heads won't work on the boss blocks, according to the catalogue.
What do you think?
Thanks.

You don't need a boss block to build a reliable stroker for low rpm truck uses, a stroker build around the 351 production block will be more than reliable. You will want to use heads that are better than stock but they won't be as humongous as those the racers use and the cam will be quite conservative as well.

This is something I hope to do someday. 408 stroker, Ford racing 64CC heads, with the small valves. Comp XE250H cam. 9.3:1 compression. Weiand stealth intake. 600 CFM VS carb. Basically just a "stock" 408. Probably build more torque out of something like that for a truck than you'll ever need.

I may some day do a 393 stroker for my 96 150 van, ain't decided yet. If I do it'll get pistons in the 9 to 1 range and it'll be built around the 97 roller 351 sitting on the stand in my shop and topped with the GT40 heads that are on the 351 in the van now. The tock F4TE roller cam will stay too. But now that gas is dropping, it may never get built.

Ive personally thought about building a 331 stroker out of a 302 donor if I can find the right donor engine.


I was honestly thinking of building it more for torque production as with my 31" tires and C6 trans and 2.70ish oem axle gears I could use some low end grunt and I doubt the engine ever will turn more than 5,000 RPM.


So I was looking at probably 331 stroker, 8.5:1 to 9.5:1 compression, maybe a hydraulic roller retrofit cam for efficiency as well as the ability to run a more aggressive ramp profile. Probably throw on some Edelbrock Performer aluminum heads, with a low profile performer intake and a 600cfm 4bbl carb.


Only thing I personally have been on the fence about is the use of a OEM ford 4bbl intake and a ford 4bbl carb.


But this is what I have thought about, now as far as giving it a try I could not say that I have but I would be willing to give it a go though.


I really don't see why a stroker couldn't be built for torque for trucks over power for street/strip racing.

Hi all, I'm new to the forum and quite new to building,

This looked like the right thread to post on... so im looking for some guidance. I have a 351w .30 over than i'm building for Torque. my go to right now is a 408 stroker kit, 351CJ 4V D1ZE-DA heads, and edelbrock performer RPM intake.

Or would it be easier to keep the gt40 heads on it now? i understand this is restricting the motor a bit, but how bad is it actually? is it worth it to drop 2k on a set of new heads?

I understand the 4v heads are more for power not torque, but its what I have at the moment, and cost effective...could i make up the toque lost with the 4v's with the right CAM? or is using the Cleveland heads on a Windsor going to give me a headache? all opinions welcome.

You should start your own thread with more details of your build. EFI or carb. etc.

You understand that to use the Cleveland heads on the Windsor block, you'll need Cleveland style pistons and an intake made for this swap don't you ? As for the torque thing, adding cubic inches will negate the so called "torque loss" that some people (not me) think happens when 4bbl Cleveland heads are used. The added cubes will only build HP and torque in this case.

I knew that in order to use the Cleveland heads i would need to do some mating of parts, i'm just not sure if it will be worth it with all the part changes...maybe just as easy and inexpensive as buying a set of decent heads? Dart, World?

also it is a carb build.

I'd go with what you have for now. The stock heads will work just fine, just get the build sorted and on the road and go from there.


Having said that, my Dad went all out and stroked his 351C to 408ci (with .030" overbore) and has fitted some trick heads by AFD in Melbourne, Australia. The thing is running about 10.5:1 compression and it puts out over 500hp from 4900rpm through 5500rpm, and has a torque peak of 522ftlb with 80% of that from about 1500rpm up.


Its a big, torquey, very fun motor but cost a pretty penny due to its 'no expense spared' build plan. You could easily get 80% of those numbers by using stock heads I would say, especially if you are prepared to do some home porting etc.
