First full pass, new engine, new car, 4.81@142

Guys,

We 've got some good news, there's another BBF Ford racer in town. Bobby Shrewsberry used to run a SBC Chevelle at Windy Hollow Dragway and decided he wanted to move up. So he bought a new 2010 American Racecars swing-arm chassis dragster from Phillip Oakley and JBM Racecars (Dragstersforsale.com). They assembled the dragster and set it up in Phillip's garage.

Bobby and I built a 559 CID engine, using a DOVE-A block, w/4 bolt main caps and ported Kaase P-51 heads. Using a lot of new parts from Lem, plus a few used parts that we had gathered, the engine made 942 Hp @ 6,600 rpm and 777 Tq @ 5,800 through 6,100 rpm, on VP113 gasoline.

Today is the season opening race at Windy Hollow,,,so the track may still have some left in it. However, the air is good and on Bobby's first full pass he ran a 4.81 @ 142 mph with a 1.05 sixty foot time. Congratulations to all involved in the work effort and Bobby we're all proud of you

Uncle Charlie

Good Job Charlie sounds like a strong combo



Randy

Thanks guys. The second pass was 4.79 @ 142.8 mph.

Uncle Charlie

Sounds like a real mover there Uncle Charlie.

Pass # 3 = 4.76 @ 143.74 mph.

Charlie

cool deal that thing is getting it done.

Good job

Glad to see the guy cross over from the dark side, sounds like you have a nice car there, good job everyone involved, but come bash time, he is going down, them motors on a stick are fun to beat, just joking, see you guys in about a month.

congrats guys! it just keeps getting faster

I am sure that was an adjustment to just changing to a dragster much less going that fast. Congrats Bobby I bet there are some 4.60's in your future

Is it Chevelle green ... ?

WOW !
Bob sure has stepped up in the last several years. He has come a long way from the days when we raced him in his white '68 Chevelle running 8's.
Congrats to Bob !

Nice power from a OEM block 557. Good Job guy's.

but why use an oem block ????? ....... thats threading on thin ice ..

great passes btw

Budget constraints Nick. He's bought thousands of dollars of new parts, and a brand new 2010 American Racecar chassis. We could have built more horsepower too, but it costs more money. At some point you just have to say "enough".

Uncle Charlie

Awesome numbers.....ET's and HP's.

Thin ice it is/was.

Lem, Thats a bad deal on Bobby's block. Was it sonic checked and filled

Does this mean the engine referred to in this thread has met its demise????

It's a dove-a block with caps, seemed to be working fine. It's also lighter.

Bobby isn't spinning it to the moon either.

Guys,

The block was sonic tested and had some good thick cylinder walls. It was not filled. The engine was good to go when it came off the dyno, with 942 Hp and 777 Tq.

Somehow, accidently during the installation in the new car and the wiring up process it got 70* of timing according to Bobby. It made a couple of short passes with that much timing before they caught it and set it back, however the damage was done. As we later found out, it blew the head gaskets and cracked the cylinder wall. The block is now being sleeved.

That night, after setting the timing back to 29*-30*, it ran the 4.81, 4.79, and 4.76. On the fourth pass it ran 4.77, but it was blowing a lot of water out of the overflow tank and they decided to throw in the towel.
