    brodix

    Greg i called Kyle about those heads he said he has $6500 into them!!, its a great deal for this set of heads, if i bought them i would have to buy a intake & have it ported & would have to have the heads milled to 66cc chambers so i think i will go with Chad Speire as i have Jesel shaft rockers & a ported dominator intake. thanks for your help Doug

    Heads

    I was @ his Shop this morning,so you must have called afterwards.
    Anyway,1 THING to keep in Mind?Its Hard to put a Price on QUALITY Parts!Its Realy HARD to compare these Heads against each other?Not Realy Sure who or were the RHS stuff is made anymore?So,I was Just Trying to Help Kyle move the Heads,He HELPS me with Parts for my Car,and is 1 of the BEST Fab Guys in the Business!!!
    Hope that they work for You?
    These Heads of His are a More Upper End Head,and will Sell thereself,once He gets the Word out?

    598

    Doug,
    The 598 must be a Pump Gas Motor!Although 5g's is a GREAT Deal for a Complete 598,its Only making 825-850HP.Which is Great if you have 650 now?
    But My 496 has Gone Faster than the 598 @ 3000lbs.
    I would be Curious to see what componets are in the 598 and static comp.?
    I Understand the Added Expence on the Brodix Heads will be More that going the Other Route.I beleive a Edelbrock (4926?) Intake is what He uses,probably under 300.00 and you would NOT Nessesarily have to Port it.But,would NEED a set of Off~Set Lifters,so you would be in the 37-3800.00 Range?It ADDS up Fast!
    Good Luck!

    598

    Greg that 598 has all good parts merlin block, bryant, oliver rods, 14 to 1 pistons and 360 dart heads, brodix intake with a grant type dominator he just bought a 565 that made 1030hp on a dyno. i think that run was his only wide open pass as he runs super street [email protected] my car in super gas ran [email protected] with my 434. i'll stick with my sbc i do hope to go faster with a better set of heads next year i'll let you know if it was worth the effort!, at woodburn i run a 5 race series no electronics for front engine dragsters, roadsters & altereds, and at madras i run pro class. thanks again Doug
