    Default blower manifold question

    Okay I searched and searched and couldn't find what i was looking for on here or anywhere for that matter.
    So my question is, does anyone make a blower manifold for a standard deck, BBC, oval port, for a 6-71 or 8-71?
    I'm sure i could have a sheet metal one made but I'm on a budget and don't want to break the bank.

    Or, I've read about using a rectangle manifold and use the rectangle gaskets. is this frowned upon or okay?

    thanks

    rect port gaskets and rect port intake is pretty common place on blown oval port motors, my blown 475 couldnt tell the difference and ran harddddd with 871 oval ports and rect port weiand intake.ive yet to see a oval port blower intake , maybe someday ill see 1 for sale somewhere

    Dare to be different, if it turns out great you can claim you planned it that way.

    The only oval port manifold I know of for a 6/14-71 is a from Mike Kuhl in Santa Ana

    Thanks for the quick response. That is what I'm coming to realize also.

    Try Roy Miersh at profesional performance products. He is in Fallbrook Ca. and builds manifolds for blowers. For what it's worth a blower really doesn't feel the heads "so to speak" just the chamber it is feeding and feul/air it is providing. I have built blower motors and you can toss me a good 6-71 and the right drive ratio for a BBC and build dependable H/P at a reasonable cost. IMLAO!

    So peanut ports are just fine for a 588 blower motor because the blower only sees the chamber runder the blower. And why did Roy go to all the trouble of virtually reinventing the blower manifold if all it needs is a chamber under it. Come all Ol Guy, you know better than that.

    Gee sport! I missed the part were it was a 588 with "peanut heads" I thought we were talking more like a 049 head on a small inch BBC. FWIW yes I do know better than that As I stated DRIVE has alot to do with volumes and CFM. M

    Drive has a lot to do with boost. Heads and cam have a lot to do with cfm and flow.

    You can built a total pig with 30lbs of boost that will get spanked by a motor with 10lbs, with the same compression ratio.

    Well understood! that was my point! A well built 468 with a 8:5 ratio and 10percent over with an 049 head and proper cam will live forever,make a butt-load of power with the proper carburation. NOW a 588 with a ?-71 and peanut heads will look cool and go nowhere! By the way when I talk blowers I speak in percents and atmospheres not boost. Boost is for turbo motors. Now if you use that term in life expectancy for indurance then I can well understand. But for a drag situation I think more on the other side. I run blown motors for short term and you run them for hours so different requirement fall into play. If you could design a waste gate for a blower motor with "on the fly" control that worked you would be retired and living the life of luxury. M
