I've got it in my head that I can put machinedcleveland heads on a 351w block--all I need are cleveland headers and intake and I've gotsome cheap performance for my windsor. With a nice cam,isit too optimistic to shoot for 400hp witha 2v heads setup?
(Looking for daily driver, around 9.5:1 comp, and sorry no nitrous)...

Is this the "holygrail" togetting 400 horse out of my 351w for real cheap?-- I know where I can get some 2v's for dirt, which just leaves machining costs, cam, intake/carb, andheaders.
Anyone have a better way I can reach this horsepower without selling the farm?

Hey,
That's a bit of a challange for sure. It has been done before, however. One of the main challanges to bolting on a set of Cleveland heads to a Windsor block is finding an intake manifold that works. The blocks have different deck heights/angles which makes using a Cleveland or Windsor intake not an option. I've heard that the 400M intake can be made to work on this combination, but haven't tried myself so I can't say for sure. A friend and I have fabricated an iscolated runner type of manifold and lifter valley pan to run this same set-up. Additionally, a couple of coolant passages have to be modified on the cylinder heads to match those of the block. BUT... There areeasier waysto make 400HP on a 351W motor. I'm sure themembersof this forum willshowyou how they did it with in-line valved heads.The aftermarketoffers some cost effective solutions in the way ofheads, intakes and cams (especially ifyou go carbureted, IMO).

Keep us posted,
Indy

the 2v cleve heads are good but not great, there are better AFR heads out there. but since you dont want to sell the farm for these, here is a link that might help

it will be tough, no one on this forum, IIRC, has done this, BUT, it would make a nice project

Its not hard to do. But, it is pretty expensive. The only company that made the intake for the conversion was B&A performance. They are either out of business or just stopped producing them years ago. There wasn't much demand. Now the intakes bring about $500 or more if you can find one. For what you will spend on having the heads worked, the intake, and the other special parts needed you could easily just buy a set of aluminum heads and a better intake and still have money left over. B&A Performance made the only intake in recent years that works. Now, there are some early Nascar intakes that might work but, they are very priceyif you can find one. No production intake can be modified cheaply.

Hey thanks everyone for the info-- I guess putting clevor heads on a windsor isn't exactly cheap performance, but I haven't totally abandoned the idea yet.

Just for price comparison,does anyone know any 351 windsorheads that give good performance for cheap?

The best cheap heads are TFS or Ford Motorsport GT40's. Also one other note on the clevor swap, you have to change the pistons. KB used to make a hyper pistons for it and the only choices for forged are custom.

heads itself are not cheap, and just think of it this way, the cheaper the head, the less performance you may have

I just bought a 373 clevor, It has the 4V heads and the track boss intake...I'm having a hard time finding head and intake gaskets though, The motor was dynoed 600hp on an engine dyno when it was built a few years ago. It pushed a fox hatch to high9's on a 150 shot of nitrous and 10.60's NA...Im keeping it NA so i'll probably get a different cam to replace the nitrous cam. Good Luck with the build

first off the cleve heads breathe better than any windsor aftermarket heads taht are street legal. the only heads better are afr205's and 225's and the canfield's. but they are strictly race heads. a clevor motor is a great setup, the maching and pistons and everything should only run u about 12-1500. the 4v heads from chi, are the best there are. they flow better than any sbf head. with those heads a big *** cam and the right intake which will be hard to find, u will be making well over 600 hp. so good luck and build the clevor motor, u wont regret it.

dont know if you went with the setup but edelbrok now makes the intake you need for this mut part #7183.summitracing. infact mine should be here any day now. the biggest issue i keep reading about is drilling coolant passages in the heads. and something about the intake gaskets. the only issue im having currently is finding pistons other wise its going smooth got the heads for 300 the intake 220 all i need is cam and rebuild kit
