Hi,

I stopped by the machine shop Saturday to check on my crank and I've got some pictures of the crank and some of the rod I plan on using.

I am adapting a steel 7.1" bb-chevy H-beam connecting rod to my slant race motor, this requires welding the rod journal sides to narrow the journal about 0.200", then regrinding to 2.180 for a 0.020 under chevy bearing. These rods are chinese made, appear to be very nice, and are very cheap ($360 for eight), but the crank work is kinda expensive ($500).

Doc, on the road

Mark,
Seeing I am "on the road" this week, try emailing your pics to Chuck Rivers (webmaster) and he can get them posted for you. He can tag them to your post if you tell him the message number (the number at the end of the URL)

Hi Mark This is a neat idea! Who welded up your crankshaft? Did you change your stroke? I would like to see some pictures when you get a chance.

Horn Automotive (a local shop) is welding and grinding the crank. I did not change the stroke, not sure how much extra cost would be involved, probably not a lot.

These rods will require some sort of block notch, but probably less than an Au rod, or one of the other aftermarket rods available.

I'll post pictures as soon as I can get them compressed and sent to Chuck.

Mark,
What brand are the rods you are using, and where did you get them? This setup sounds alot like what I have been looking for; I want to get some rods that are definately good for 400 HP or so, because I would like to do some HEAVY super/turbo-charging on the motor. I just have to be able to beat my brother in his big-block beating small-block-Chevelle.

 Post subject: good question...
PostPosted: Wed Feb 20, 2002 10:45 am 
Hi Mike,

Good question...they are supposedly made in a chinese factory, have no markings on them, the box only says CRS-71 (or something like it), and has a panther image on the box. They look like Eagle H-beam rods. I bought mine through Chet Herbert (ad in National Dragster). A friend of mine bought a set of Hughes Engines rods and they look the same as mine, no markings except for a panther image stamped on the beam in ink. Mine have ARP 8740 bolts, his have MSA bolts. They use a cap-screw bolt. I cannot imagine a slant being able to hurt these rods.

Let me know if you need more info and I'll try to help out.

Chuck has the pictures, they should show up here soon.

regards,
mark

Mark,

Thanks for the info. I'll have to wait a while to build my engine (too many irons in the fire already), but I'm trying to collect all the info I can so when I can build the engine, I'll know exactly what I need. ...I can't wait. Continue to let us know how your project goes.

Mike

Hi Will,

What are your plans for the crank? Custom rods that use a chevy bearing? My crank is now welded and ground to 'look' like a bb-chevy rod journal (0.020 undersize) and I'm planning to use bb-chevy 7.1" rods.
