Crankshaft is a billet piece with Honda rod journals (1.889”).  The rods are 6.750” long and incorporate 3/8” rod bolts instead of 7/16” so they can be pulled in tighter to the bearing itself.  If I hadn’t gone with the .595/.602” lift on the cam, the rods would have cleared the cam with the smaller base circle.  But the rods did require a bit of tweaking at the tops of the rod bolt areas to clear the camshaft with the extra lobe lift.  Targetted for 0.050” clearance everywhere, not just the four rods that came close.

 

The new Mummert single four dual plane intake was used with a Holley 950HP carb (carb actualy flows 824cfm at 1.5Hg).

Any chance someone made a video of dyno pulls that might get posted?

Ted' ALL YOU GUYS did a GREAT JOB AND THAT'S ALL THERE IS TO IT!!!!!! We're really proud of all you guys period D.

Long live the Y block! Super Great job fellas! When will that "crate" motor go into production? 400hp off 87 pump gas with a good idle? are you kidding me? those Y blocks would sell like hot cakes!

There has been a lot of comments in the past with respect to the oem Heads being the serious power limitation. It seems that there is a generally held belief that Aluminum heads are much better. However, some aftermarket or high performance heads are being cast from Iron. My impression is that just making Heads from Aluminum doesn't make them significantly better, from a performance point of view. Lighter yes, (not of real benefit on a Dyno) and maybe a little better for heat dissipation, & controlling detonation, but not necessarily better overall.. Comments?

And a question for Ted; Was your Y-Block the only entry at the Engine Masters with Flat Lifters?

Paul,

   Aluminum heads are only better in one area, given the same ports and valves. They're lighter. Also, it's generally accepted that they are easier to repair. If they are dimensionally identicle to an iron head they'll actually produce a bit LESS horsepower! The aluminum. head transfers heat from the combustion chamber too quickly. Most aluminum heads are equipped with better ports and valves than the OE iron ones. The material around the combustion chamber is thicker to slow heat transfer rates and typically they'll have a smaller combustion chamber for more compression. It's common for an aluminum head to carry a point more CR and be able to use the same octane fuel  with out pre-ignition. Improving a stock 50 year old head shouldn't be a major problem, after all it wasn't designed to carry the amount of air we look for today. However, it turns out to be somewhat more difficult than you'd think. Ford did a pretty fair job on them, then completely blew the SBF 260/289 heads.

I believe one other benifit may be better combustion chamber design.

The Y design in all probability has a lot of swirl but the more modern heart shaped combusion chamber should add some performance.
