clevor thinking 2
why would a clevor grenade? the bottom end is a basic windsor, weather it be a 302/351/stroker. as long as the head conversion is done right (making sure you dont have coolant pouring all over the place when you fill the radiator, everything is fine. the ONLY problem you *could* run into is if you used a high lift cam with normal windsor pistons, because the vavle reliefs arent cut in the right spots for the canted valve heads. they do make pistons especially for these conversions, or a "boss 302" piston would work.
there is tons of helpful advice on these forums, but every once in a while you will run into a know-it-all who really doesnt know jack shiat

So a 302 will explode with Cleveland heads but not with Windsor heads? or is it just that all 302s will explode? Of course if you over rev any engine rods will make nice venitlation ports in the block, but just having them explode because of the heads?
I've spun my share of bearings, thrown rods, and dropped valves, and it was always due to something being stressed beyond its limit repeatedly. Never have I had something 'explode' because it had a different type of head that would fit correctly. Sure spin it to 9000 rpm with heavy speed pro pistons and stock rods with stock bolts. It will go boom. Guaranteed. Drive any engine with stock parts in it like that and you are asking for a pile of scrap iron. Duurrrr.
Sure headers might be expensive, but I bet a set of iron manifolds would get you by untill you can afford some headers. Every engine you build will be expensive. When you started looking at that, if you recall, we told you about how much the intake would cost and what it takes to get one. Got a link so we may tap into this vast array of sbf knowledge?

I't won't blow up.
There are so many Cleveland horror stories... 99% of them seem to come from guys who were running them up into the 8,000+rpm range, probably back in the 70's and 80's. Now you can have a better balance job, buy better rotating parts, and use a camshaft that will pump out some torque at the lower range. Just don't wind the living daylights out of your engine, you risk making a mess out of any engine if you choose to rev it like a ricer (unless you are going to spend some big $$$) Don't give upon it, just put some money aside and shop when you find deals. You can find an intake, just make sure you don't buy junk, if you need more money...work more.
My 377 Cleveland seems to defy the bull s*&% and put out gobs and gobs of torque, peak horesepowerat 6300 and peak torque somewhere around 3600. At 425hp-426ft poundswith CHI 2V heads and 10:1 compression it will push around my 71 just fine.

Headers: I've been using cheap hedmans for over a decade now, but...due to the taller block height of a W block, they were a little short. Adjustment required some bending and rewelding. Both have added weld on the outside now. My R&P also required rerouting one tube, so I have invested some into making them work, but not $600, maybe $300?
PS Good to know a few Clevors besides mine exist out there.

this is already takin care of. the pistons are cleve boss pistons and are already in the block.
Guys I want to thank you all for this reinforcement, the clevor is so cool and I want to build one so bad, but money is an issue. due to college i have been out of work but am now searching hard for a job. if i can get the money to buy the block than i will do it.

the only problem is will they fit in the fox platform. if i use some windsor headers they wont flow that well and if i get some cleve headers they wont fit. but im thinikin that the windsor headers might suffice for now.

Oh crap, you're putting it in a fox body, that might be easier than a 66. I thin kyou have more room. Just use regular 351c headers. I think there is a company that sells conversion headers for $600 but yeah, you can find something cheaper. Just get some used headers on ebay for any car and you might have to move a few tubes. Or, if you can weld, you can make a set of headers. There's a guy on ebay that sells header flanges for all kinds of engines for like $20-30. Take your time and you can get it done. I've been working on mine for about a year.
Oh, and for that *** that said these things blow up all the time, his engines probably blow up all the time. I don't know why anyone would sell parts for a conversion that didn't work well. Now, the factory BOSS 302 engines had weak pistons and yes they were ticking time bombs. I learned that from a lot of B302 owners, they suggst swapping out pistons ASAP...on a stock BOSS 302. Use forged pistons and you should be alright.
