    [QUOTE=jerry clayton;

    The head bolt cracks was common point and can be prevented somewhat by putting the tapered plugs in the water holes to support the deck and then drilling to size necessary[/QUOTE]

    yep i did a sbc and seen bbc as well . i tap the big upper water/ steam holes in the deck and then used a soild iron pipe plug there hard to find now with out the dip in the threaded inside of the plug. then i tap out some round stock to hold the pipe plugs and drill for steam hole s faced the square drive and shoulder off the top in the lath .so there was less to deck off .i know that they sell a hex pipe plug but like the job better with the iron plugs more iron in the deck when done .yep dave i went around and around with a guy i built a sbc blower engine all the work and a block that may not hold the boost load of a 871 should of use a shp dart block .but he did not want to spend the money .oh well when all said and done with his old block the shp block was only a bit more

    Ok, thanks Jerry! Soon as I get some things together and money freed up (dang holidays and some stuff with my kid) we'll be getting going on it. I suppose with the short stroke the raised cam location wouldn't be an issue anyway, right??

    well i am not jerry but with the small stroke crank and smal journal rods you do not need the raise cam . if you are going to stuff some thing like a 682/ 654 @0.50. 274/280 110lift roller cam in it use the big block cam bearings and the 903 lifters if you need off set and some big valve springs and let it fly get some heads that flow good .

    OK Pat, am I overlooking anything significant for now, or is it time to start lining up parts and shipping them out to Bay City????

    Just curious----same short block as above, but to stay a bit more "period correct" (for whatever that's worth) would there be a set of cast iron heads that could produce good enough flow numbers to support this engine??? Don't think I'd sacrifice performance for looks right, though.

    yep could make some thing work like a RHS or dart s and make them look old plug the bolt holes JB weld some humps on them or get some alum and paint them

    The Brodix -10 (23 degree heads) flows 262/166 @0.600". RHS Pro Action cast iron 235's flow 292/191 @0.600" (14 degree heads). I would think you'd have to be turnin' 8500 though, to pull air through 'em with any kind of velocity to fill the cylinders. That would require more cam than I showed in the 700 hp DynoSim. Jerry and Pat, what do you think?

    Could have the tricked out aluminum heads then do a bit of grinding on the accessory bolt pads, fill the holes, weld some camel humps, then with some paint...... Thanks Pat, that'd be kewl, huh? At least to the casual observer it would appear to be old style heads!!!!

    Man, this project gets to be more fun everyday!!!!!! Having an absolute blast and still just in the planning stage! Soon as the chassis table is empty, the '57 frame is going on it!!!

    Looks like we'll be needing something inbetween those two then, maybe with flow in the 270-275 range?????
