[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 moreLast edited by pat mccarthy; 12-15-2010 at 01:18 PM.

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 .Last edited by pat mccarthy; 12-15-2010 at 07:34 PM.

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.Yesterday is history, tomorrow is a mystery, Live for Today!

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?Last edited by techinspector1; 12-18-2010 at 09:43 PM.

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!!!Yesterday is history, tomorrow is a mystery, Live for Today!

yep i posted the cam what i think would be a good place to start, line 34 682/654 @050.274/280 .lsa.110 i think the 220 runner heads should do the trickIrish Diplomacy ..the ability to tell someone to go to Hell ,,So that they will look forward to to the trip

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
