I drove one in the early eighties. It was a small block (327?) with a 280z rear end. It felt pretty balanced.:thumbs_up: |

Back in the 70s I finished a 56 AH with a 301 Chevy, PG and 67 Corvette rear for a girlfriend. What a rocket ship. It was just as fast (I'm sure it was faster, but a girl drove it) as my friend's 70 LT1 corvette.:drink: |
Any update on fixing the blower? I located the crank spacer, pulley, and the belt.

Oky doky, the staff at the university apparently bypassed the minor detail of control software for the laser scanner, so it won't be operational til the fall. Balls to that, so as soon as I sell some plasma, we'll be handing it off to bird's welder pal for refabrication. May the force be with us.

You won't see any funky inline motors under Cambria's hood. Now if I get my hands on a 787b, no promises. |

Do you mean you'd put a funky inline under the hood of a 787b or the R26b from the 787 in Cambria? |

I have piston ring pliers btw, before you go out and buy some.

The blower is now welded up, and ready to be re-machined. Now, to have Doug help me convince John M. to do the work.:leaving:

Quote:
Word bird! That's awesome. Just have Doug use his special East Coast charms on John. . . Also, I'll extend the same offer to John as to anyone doing substantial and/or skilled work. If he can drive a potential 10second car and donates "value in kind" to the project, he can drive it when complete. (Yes, Ron, it will be completed :smack:) |

Can't wait. :hail: Wonder if I took pictures of the damn thing before he fixed her up. |

Today we pressed out the shaft from the snout and began some machining of the snout and bearing plate. The shaft itself was fine but discovered that the axle the shaft spins on was bent like a mofo. (Holy Crap Joe). So they'll have to make a new one from scratch. Also the plate was not even close to flat so they had to machine it down about 1/16th in total. That we can make up with a shim and an extra gasket, if it turns out there isn't enough clearance between the plate and gears.
But all in all, it looks like it's going to work. The shop is very busy, so my cousin will work it in on the side as he can. Maybe a couple weeks. |
Dropped off the pistons (w/ rods attached), crank, balancer, and flywheel. The pistons need to be cut for the larger valves in the new heads and the whole assembly needs to be balanced after the cutting.
Danger Will Robinson. Troy from FPS sort of grimaced when I showed him the pistons. They're press-on and he warned that no matter how careful they are, occasionally one cracks when separating the rod. |
I have NEVER cracked a piston when pressing the pins out. Yes, it's possible but out of hundreds I did -never had one crack. It's all in the support of the piston.:drink:

Hey Ron, or anyone, do you know anything about fuel cell rules? I decided that in the name of safety we'd replace the stock stamped metal fuel tank with a smaller foam filled cell (pretty cheap really). But are there any restrictions you can think of about how and where they're mounted etc.?
|
1.4 FUEL SYSTEM All fuel tank filler necks located inside trunk must have filler neck vented to outside of body. Vented caps prohibited. All batteries, fuel lines, fuel pumps or filler necks located inside trunk require complete bulkhead of at least .024-inch (.6 mm) steel or .032 (.8 mm) aluminum to isolate driver compartment from trunk. Fuel lines must be located outside driver compartment. Fuel tanks must be within the confines of the body.

Re: Battery I have a legit battery box, but didn't releaize that a bulkhead was required between the back compartment and the front to rear mount the battery. Mmmm. . . |
Quote:
With the battery you don't have to have a bulk head as long as there is a vent tube on the box to the outside of the car. There are only a couple of companies that make NHRA legal boxes. One being Taylor which is what I have in the Chevelle and the Cobra. It also has to be mounted so that one of the hold down bolts goes the the frame or subframe. |
Oh, and if it is in the back we have to have an external shut off switch that is clearly marked.
|
Picked up the internals today.
Ron, I decided to get another set of rings (while we're at it). Can I drop off the pistons and new rings with you tomorrow at the cruise and you can install the rings at your leisure in preparation for assembling the bottom end? |
What rings are they and are they file fit rings? Did you find out what the ring manufacturer recommends for ring gaps with a blower? We need to check the end gaps before we install them on the pistons.

Did you get this exact part number which is for a 4.000 bore? Wasn't the block bored .030? If so, these are the wrong size. If you have the correct size rings the next step is to check the end gaps which you do by installing the rings in the block and use a feeler gauge. Considering the low boost we'll be running and the fact that this will be a drag race engine I would set the top ring around .020-.022 and the second ring around .012-.014. What do you think Glenn?
Make sure you have the correct rings first and then we can arrange a night for me to come over and we'll check the rings and start building the short block. |

Well Ben and I honed the block tonight and then installed new main bearings along with the crank. Then we checked the end gap of the new rings which were .019 on the top ring and .015 on the second ring. We installed the new rings as well as new rod bearings and then installed all the pistons.

Tonight was a very productive and fun night working with Ron. In addition to working on the motor, I gave him a ride in the Vette and he gave me a ride in the Cobra. Good times.
I actually got a fair bit of good video. Here's a little for now. I'm behind on a bunch of other video, but I'll get back to it. I'll cut this to some porn music later for enkei. ------------ PICS Ron searches for something. Hours later, he's pretty sure he knows what it is. Ron studied from his father how to drop bearings. So he's pretty good at it. ;) He's also good at putting them in. Block. |
I am quite sure that is the first time I ever saw someone hone a cylinder dry.
