One place says they'll grind rods and mains to size for $100, another wants $200. The $200 job is clean it, grind rods and mains to size with proper radius, chamfer oil holes, and polish. I didn't get details from the guy that charges $100. My feeling is the $200 quote is from a higher quality shop but I dont' know what's the going rate these days. This would be for a stock forged 440 crank. The latter shop also wants $45 to magnuflux the crank to check for cracks.

I also asked about the cost to offset grind the rod journals to increase the stroke and that raised the price to $300. 69 EF8 GTX 440 auto 72 EB5 RR/GTX 440 auto 70 EW1 GTX 440-6 4 spd 70 EF8 Satellite 318 auto (452 coming soon) 70 FK5 Satellite 318 auto 71 FC7 Cuda 340 4 spd

The more material they need to cut off increases the price tag(thats more passes on the machine).. I paid $420 to have the rods cut .020 BUT I had that one nitrited.. also different areas of the country charge different prices based on labor cost Last edited by MR_P_BODY; 01/18/14 12:20 AM.

They were both polished, chamfered ready to run. Thats a good price... I paid $400 for just turning down the weights from a known shop on here.. I believe I got ripped off on that one... but I dont deal with that shop any longer

I had $2000 into that crank... I sold it and took a pretty big hit on it... that was BB stuff The guy at the shop did make the comment that after $300 in the crank for the off-set grinding plus almost $50 for magnuflux to check for cracks, etc. that I might just want to consider a new crank for a few bucks more. So sounds like he's probably an honest guy. I don't know what kind of new crank $500 will buy but I suppose it's going to be at least as good as a rebuilt 40 year old one. 69 EF8 GTX 440 auto 72 EB5 RR/GTX 440 auto 70 EW1 GTX 440-6 4 spd 70 EF8 Satellite 318 auto (452 coming soon) 70 FK5 Satellite 318 auto 71 FC7 Cuda 340 4 spd
