 Todd Ferguson at Sacramento last weekend for Division 7 Finals.   Nice to see a real 56 T bird with the original Y block gettin' it done.

Tell us a bit more, please.

What was his speed & time? Did you build the engine? If so, can you tell us a little more about what's in it?

  Is the link not working for the video?

[frnkeore]

There is no text with the video and the timing board is to blurry for me to make out the ET or speed.

6.11 @111 in the 8th

Very nice sounds great. Sounds a lot like an FE maybe alittle deeper sounding

[mummert]

 
 The engine is a 355 ci Ford Y block.   14.5:1 compression, 3.860 bore x3.800 stroke.  1.97" 1.51" valves , our race version alum heads and tunnel ram intake. Cam is 268 @ .050  .630" int    263 @.050" .615" exh

Thank you, it is a fast, great sounding car.

What was the trans and shift points?

[mummert]

  The tranny is a C4, 7000 rpm shift points.

Very impressive Y Block! That should be well into the 9s in the 1/4 mile, as my Fairmont only goes 6.30s at 107 mph in the 1/8th, and thats 10.0s at 132 in the 1/4. What does the T Bird weigh? And that is "all motor", I assume? Do these race Y Block heads retain the stacked intake ports, or are they like the Kasse Engine Master style? By the way, a friend of mine has the Kasse Y Block from Engine Masters in his shop, very trick piece!

Great car, great pass - Little air time for the spectators, nice and smooth, no drama.   Good combo - .4 quicker than the left lane at 8 MPH less. 

That track not have 60' clocks?  I didn't see a cone, that's odd.

 The ports and locations are stock.  Valve locations are bit different, a little back and a little in but all stock parts fit. 

 The Nova is a throttle stop car,  that video was taken in Super Pro electronics class.

 The T-Bird is all motor 620hp  no electronics. We run it in Pro and Super Pro.  So shes pulling double duty.

 Most tracks don't post 60' or 330'  times during eliminations.

Is the Y block prone to the same issues as the FE with cracks developing between the number 2&4 main and camshaft area? Just curious if the Y block firing order has any effect on main bearing longevity if structurally similar.

[mummert]

 Yeah they can do the same thing, but its a 90* V-8 thing as much as it is anything.  4 bolt main caps, cross bolted main caps, splay 4 bolt main caps are all things people do to make the blocks more rigid.  Most people assume that V-8's try to put a bunch of downward pressure on the main cap, but the 90* bank angle, crank counterweights and the other rotating parts tend to turn a downward motion into more of a side to side motion. When they get run hard they tend to skid the main caps side to side and that motion is what breaks blocks.  Stock main caps deflect ALOT.  Billet main caps that we have made over the years measure narrower than the originals and fit in the block harder.

I know people have fallen in love with the90* V-8 but it has many problems considering its a pair of odd fire 4 cylinders linked to the same crank.  Exhaust issues come to mind, that low rumble sound the vV-8 makes is an odd fire sound.
