Getting ready for Bonneville(rebuild)

[Rex Schimmer]

I have seen way to much of the inside of your motor!! That is real "comprehensive" destruction.

 Found a very pinched fuel line which could have caused problem. It was under the air intake elbow.

  Our fuel lines are setup and split so that one fuel line goes to bottom fuel rail on left and to top rail  on right and the other line to top left and bottom right.  So just pinching 1/2 of the lines but still not good.
 
  On warm up when tweaking the throttle, I said it doesn't feel as responsive as usual.
 
 Pinched line could be the culprit?

The cam.  Should buff out





Crank is out, bearing didn't look too bad.



Time to get these sleeves out.  What a pain in the butt that was!  My forearms and shoulders are sore today!







At least we have some pieces to work with....

We took our old AA block apart to see what it looks like. 



We took our Bebe hone to the cylinders to clean up the top for easier extraction.



Cylinder walls look pretty goods.

[bvillercr]

Pistons look good



Crank turned over real easy by hand and bearings look good too.



I had a break at the dental office.  Getting work done now.  Lol

  The AA motor has been sitting in the shop for 13 yrs and covered with a blanket, it's hard to remember exactly.

  looks like it was ready to run but wasn't because I bought the Stage 8 block.

  I have the same NASCAR Goodyears you are using. How much tire growth do you see? On my land speed 25's I use 25.7 as a number the GY engineer gave me. I am mounting these on an 8" rim.  Thanks  George

[jl222]

  Growth is hard to measure I figure 1'' on the conservative side  But years ago when I went thru
the exit speed trap at 272 mph  I had to figure 11/2'' to match the tack speed.
 Ir could be more. leave plenty of room for growth.

  Thanks for the info, just what I was hoping for. By the way I ran TAD for many years and saw up to 46 lbs. boost and could never see the impressive carnage that you experienced. I'd be checking the cam for straight.

[jl222]

  Cam turned freely in block before removing. Its a large journal cam made out of high dollar material and makes the cam out of our 528 egine look wimpy. Really hard stuff that top fuel uses.
 Hope Crane cams can polish it up.

 528 engine had whole left front blown off and welded back.

 Tires... being conservative with 1 in growth was for interring data into my Bville Pro computer program which calculates speed at rpms.

  What car and class are you running?

  Troy pressure washed the 528 block and I bb honed the cyls. Some look ify. We'll take the block to Steve Moodie's shop and see if he can hone it for the 4.310 Ross pistons that we have, if not we'll
replace the sleeves  with 4.25 sleeves and bore to 4.310.

Tire growth: 

My late friend John Horsman was the chief engineer of John Wyer Automotive Engineering when they ran Ford GT40s and Porsche 917s in endurance racing (Le Mans, Spa, Monza, etc). He told me that he used the figure of 4% tire expansion at 200 mph in his calculations. This was for bias-ply tires which were standard at that time.
