    The pic is of the new E'brock Clevor Performer RPM for 351w block w/Cleveland heads.
    There is also a 302 version!
    Can't find a pic right now.
    They run just over 300 bux at Summit.

    It is a Clevor intake.

    You can use 351c heads on a 302 or 351w engine with these.

    Used to be that you had to pay through the nose for an obsolete B&A Performance adapter intake, or use 4v heads with one of the original Boss 302 intakes.

    At around 300 bux, this is still kinda expensive, but only about half the price of what the old discontinued intakes bid up to on eBay.

    Probably a much higher quality intake too, as well as better flowing with modern tech.

    E'brock has the 190cc aluminum 351c heads now, so you could use those as well on your 302/351w block with one of these intakes.

    No.
    Pipe plugs (like freeze plugs) have to be put in the heads on the combustion chamber side, then redrilled on the intake side to pass water to the t-stat housing.
    Also, for the most part, Clevor pistons must be used.
    If you have any sort of decent cam, the valve notches must be at an angle like Boss 302 or 351c pistons. They are a common part though.
    Cost a little more than regular pistons, but you know that when you are cloning a Boss 302 engine...;)
    Oh yeah, Boss 302 push rods too.
    Everything else is Cleveland or 302, depending on what part you are talking about.

    Also, just like 351w heads, you need different head bolts.

    How does a 302 with the Cleveland heads perform? What kind of horsepower and power curve are you looking at? Would it be a torque-monster or a high-revving screamer?

    it depends which heads you'll use. I've read that 351C 2v heads are good for low end torque, and 4v's are great for high revving use. I think the 302C (aussie heads) has the best of both.

    If i do build this Boss 302, what headers will fit the Maverick? And does anyone know, can I make the Boss 347?

    Like mentioned, it depends on the heads you use.

    With such small displacement, and a fairly small selection of off the shelf pistons, you should stick with closed chambers.
    That leaves 70 model 4v heads for high rpm use, or 302c Aussie heads for torque.
    This is assuming you go with stock castings.

    The E'brock castings are based on 2v ports, as are the intakes from what I can tell, so as a package they would be the ultimate combo.

    They still have large ports and big valves compared to W style heads, so this combo is no slouch. It would be akin to putting high line Victor or AFR heads on a 302.
    One big plus is the ability to use Boss 302 headers with very large primarys if you so choose.
    Tubular Automotive makes B302 headers for our cars in a choice of tube sizes up to 2.125" primarys. Much bigger than you will ever find for your radical 347 with W style heads.
    The Cleveland heads exit the headers in a downward direction, instead of out the side and into the towers. Therefore C heads don't have issues with the pipes being limited by the towers.

    You can, but if you're going with a 351-based combination, you can just stroke a 351 Cleveland.
