The original game plan was to replace the 351W engine with the 335 Series V-8. If the engine has ever overheated you face the potential for cracking, which makes the casting a throwaway. If you are running stock gears I am afraid the 4V heads may be a disappointment since getting the revs up faster will be where these heads shine the best. The reduced friction will provide a more durable performance. On the right is the head you do want with its 61-64cc wedge chambers and 2. The Ford Australia Cleveland head combined the 2V ports with 4V wedge chambers—which is the best combination. This drives the cost up.
The 4V heads are the biggest advantage a Cleveland has over the other non-performance engines built by Ford 351W comes to mind, along with most 302s. You also have more torque. New to the muscle car world and looking for some guidance. It took the heavier tall-deck 400 with its 4. But now I have some problems: During my yearly small overhaul I have detect that my camshaft is defect one cam for cylinder 3. Iron block weight 215-225 pounds. The Australian 302 Cleveland heads have small wedge chambers, which means greater compression if you place them on top of a 351C.
I think some of this is an opinion thing, but 4V heads are in no way too big for the street. If the engine has ever overheated you face the potential for cracking, which makes the casting a throwaway. Because the mixture is compressed and ignited, it lights off more rapidly. A roller cam offers you the most aggressive valve action without sacrifice. The 190cc heads have 112cc exhaust ports and 62cc or 72cc wedge chambers with 2.
I won't try to stop you from buying one but I also will not recommend it. It increases torque by giving the engine more of an internal mechanical advantage. Cleveland blocks were produced in two- and four-bolt main configurations, with this one being four-bolt. The 4V 351 Cleveland was not designed for trucks and station wagons like the 302 and 351W engines. Manufactured from a high-quality aluminum material, the manifold also has a natural finish. It does sit a good bit higher and may cause clearance issues with your hood, so be sure to check that out first if you go that route.
Proper Assembly Technique When it comes to assembly practices, engine professionals stress two main areas: cleanliness and double-checking your work. The 2v heads have good ports for the street if you want low-end torque performance, but I just don't like the large open chambers as they don't promote efficient ignition in the combustion chamber. These heads are easily upgraded to screw-in studs, guideplates, and adjustable rocker arms. A roller cam offers you the most aggressive valve action without sacrifice. Torque equals the downward force of the stroke times the length of the lever or arm. The wedge chambers deliver better quench and power. If you want to build a real badass truck with the weight advantage of this engine over a big-block, opt for the odd-duck 400 Cleveland.
My question is should I upgrade to a 4V? Aluminum block weight 105-110 pounds. Australian Cleveland castings remain highly sought after pieces in North America for those seeking greater sums of power. This means going beyond 4. Otherwise you are wasting money. Ford issued a bulletin that addressed how to identify these engines. Ford wanted three basic V-8 engine platforms—small-block, middle-block, and a big-block.
This gives you 40 additional foot-pounds of torque. Even check it thrice and sleep better. Finally I would like to thank the team for becoming a member and would be happy for some feedback. Another way is compression ratio. This is a grand opportunity for me to provide additional dialogue and clarification as I believe it bears emphasis. More affordable kits have off-the-shelf parts.
If this is the first of many upgrades you might consider inputting your eventual goals rather than buying several different carbs as you progress. Is it just for cruising? Ford called it the 335 Series V-8, a smaller cousin to the robust 385 Series engine. Fill out a custom engine quote form and we will get a kit priced for you. Is this a good idea? The good news is the availability of reproduction blocks and a wealth of aftermarket cylinder heads for the Cleveland. A good rule to follow choosing an intake manifold for your Cleveland is to ask how your classic truck will be driven most of the time. Some of us guys in Europe have been informed that there is a very interesting forum for 71-73 riders. Remember, you increase torque when you increase the length of the arm.
