[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 :HMMM:should of use a shp dart block .but he did not want to spend the money .oh well:D 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??Quote:

Nope. A 3.25 stroke, 4.125 bore rev the snot out of it and drop the hammer!!!! Not my fault though, Richard, Jerry, and Pat let me talk myself into it!!!!!!!!!!!!!!!!!!!!!!!!!:LOL::LOL::LOL:Quote:

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 :3dSMILE: or get some alum and paint them ;)Quote:

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?Quote:

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

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 trick
