New Y-Block speed record

[thatdarncat]

On Sunday Timmy McMaster ( Y-Block Guy ) went 192.365 mph with his 304 C.I. Y-Block powered D/GR roadster at Bonneville. He had hoped to try for 200 mph on a later run, but on that pass, right after letting off at the 3 mile mark and running about 180 mph, he ran over a header collector tube accidentally dropped on the course by a previous competitor, which damaged the rear suspension and blew the right rear tire. That ended his weekend. My sources tell me that probably gives him the bragging rights to the Worlds Fastest Y-Block. In past years many here probably know he ran a Y-Block powered Ford Pickup at Bonneville.

Also this past weekend the Rolling Bones Hot Rod Shop Ran 193 mph with their MEL powered roadster, which runs a different class than Timmy McMaster. They were also looking to try for 200, but it sounds like they had engine problems and are done for the year.

A couple of great accomplishments.

MEL and Y-Block, the trailing edge of technology, but carrying the Ford banner proudly.  The GM guys are scratching their heads.  "They must be cheating"  "Everybody knows Fords won't run"... A dump truck motor and a land barge motor

     Anyone with more info particularly of the MEL effort, don't be bashful, tell all!

The MEL is in the Rolling Bones hot rod shop 32 Ford entry.. It is built by Ted Eaton, Lorena Tx.  It is a de-stroked 383 at 371 inches to fit into the Bonneville class.  Joe Craine  ported heads, Victor intake from a 460 on a custom adapter. Custom made billet solid roller cam by Comp.. I have not seen a dyno sheet on this one, but with a solid flat tappet  cam last year it made a little over 500 hp.  I suspect this effort makes a lot more.. Maybe Ted will chime in once he decompresses from the trip

Love the Y-blocks, got a couple myself

Sounds like I need to port another set of heads and tweak the intake manifold a bit.  There is another set of heads that should wake up this combination, but they may not be available.  Joe-JDC

     There is more than one head casting for the MEL, do we know which one was used here?

I have ported both the tall port and short port heads for various folks, several of both.  I like the short turn on the short port heads best.  Both can be made to work with lots of time.  Joe-JDC

I like the short turn on the short port heads best. 

 

      No doubt, but I still like the idea of area, particularly on big cube intentions.             


      The "tall-port" version was made available both first as a true "Heron" example, and then later another with a small excuse for a combustion chamber being present; any comparisons between the two?

371 cubic inches is not particularly large for an engine, and a port needs velocity to fill a cylinder fully.  This class at Bonneville has a cubic inch limit of 372, IIRC, so trying to keep a little wiggle room for honing and re-ring.  Joe-JDC

[pbf777]

     Yes, I understood, but I was just commenting on my own intentions of the use of the 462 cu. in. block with a small over-bore permitting the use of say 385 series piston forging slugs (machined for the application) and ring stacks, with the crank pin journals turned down and offset to either Chrysler Hemi or BBC, with a capacity of somewhere of 500 cu. in. +/-.

     This all intended for my '60 "J" code T-Bird incorporating one of the "Super Marauder" 3-duce intake set-ups that I have collected, and solely for some hot-shoe driving on the street, no real racing endeavor, probably nothing greater than one horse per cube, but just lots of pull.  You-know, .................for when the kids with their import laugh at my old car & not to mention the old fart driving it!

Not to hijack the thread, but 550 cubic inches is possible with small overbore, and 4.500" 460 crankshaft.  Needs some machine work to fit the block, but has been done already.  I ported a set of heads and intake manifold for one.  Joe-JDC

That is awesome the record gets set by a YBlock in a class where i'd assume most other cars are SBC powered. And the MEL too. Good job to those guys.

Just to be clear, this car didn’t set the Bonneville class record, just the “unofficial” World’s fastest Y-Block record.
