check with headers by ED. I know the route I'm gonna take is a header plate with adapters and weld up to a set of headman headers in my application. Just cut off old header plate and weld on a new plate. headers by ED has lots of info and maybe knows something else for us??

 

The B&A manifolds I referred to in an earlier post are wet manifolds, just like a 289/302 or a 351W. There are minor mods that need to be made to the M or Cleveland heads for the conversion. These mods can be done by any auto machine shop.
A Boss 302 intake will work on a 289/302 with the 4v Cleveland heads. Still have to modify the water passages on the Cleveland heads
As far as the exhaust goes, there is such a size difference in exhaust ports, the351M/400 and Cleveland 2v manifolds will not interchange with Cleveland 4v manifolds. Overlay one of each gasket. You will see that in some places the "inside" of the 4v gasket is "outside" of the "outside" of the 2v/M gaskets.

Don't confuse the above with installing 4v Cleveland heads and intakes on a 351M/400 engine. As previously mentioned, the M/400 intake is wider than the 351 Cleveland intake due to a taller deck heighth on the M/400 block. The adapters I have used for this swap were aluminum plates that fit between the intake and the heads. They were for all purposes, spacers. Some custom fitting and port matching were required to get everything to fit. I am not aware of a "custom' intake for this swap. Not saying there isn't, just that I have never seen or heard of one.

Just find one or a pair of 2BBL Clevland heads.
My 77 F-150 has (1) 2bbl head and (1) 351M-400 head on its 400.
It was that way when I bought it. and it runs fine so I'm not going to mess with it.

 

Thanks for the reply Bronco man,
on going with a D5AE-BA reply and will actively pursue it, but transportation is, well, transportation. I'm sure fit is as quoted, but, we are trying to keep a prepared head and keep it matched side to side. Have only ever seen one D5AE-BA and never listed on a chart as to application. D5AE-BA frequently seems to be on other parts and have noted this, but, will be happiest with TWO D5AE-BA heads in posession.
Thanks for the consideration. Dan

 

There are numerous adapters for C/M heads on a W block. Price Motorsports makes some as well as an intake like the old BA (Biddle American). The W is a wet manifold and the C/M is a dry type. The biggest problem, although workable is the square water port that is near the front of the heads and matches a similar water port in the C/M blocks. If mtd on a W block, that port in the head has to be machined round, threaded, and a Dormer plug screwed into it. Then you have to drill a water crossover hole at the water crossover passage in the W intakes. The Head bolts will match from W to C/M, maybe some modification of the head gasket jacket holes. The procedure used to be shown in the SVO catalogs---dont know, haven't looked lately.

Now---heres an idea that I have not had the opportunity to try that usually gets "gasps" from the so-called experts. Why not W heads on the C/M block??. Many, many, aftermarket and better breathing W heads available. Why not do the reverse of the clevor---Plug the square water port in the head mating surface of the block in the same manner. Round up an intake adapter (i think Price/M has one that will work). Close off (w/plate) the thermostat housing on the C/M block and use the intake thermostat housing on the W.

Except for the intake adapters, I see no more of a problem with the rest than is with the Clevor conversion--------go ahead somebody, tell my why not . Just think of all the heads, headers, etc available for the W's that are not available for the C heads. Now, if you have the bux, the Aluminum heads for the Clevelands are really great.

 

i have a 82 f-100 and we took the 302 block and put 351 windser heads on it off of a 74 gran turino,elderbrock carb,elderbrock high rise intake,hooker headers are on the list next but i was just wanting to know what else can i do to get more horsepower.....its geared for top-end really dont know how fast it will go just needing some info on maybe doing some stuff to the transmission or anything will help bc i dont know much about building a motor i had it sent off and done for me so any info will help........thank you.
