Engine hone question
 

I need someone to hone my 305sbc so I can put in new rings. Motor has like 10 passes on it but rings(total seal) I guess didn't take or hone was wrong? I am in the Middle Ga area. We have a guy local that has a new cnc hone machine but he doesn't do stocker motors but he does do lots of dirt track stuff. Just don't want the wrong hone done.

Randy Cassels in south,ga would be a choice. Outside of Georgia, I would consider Warren racing engines or Randy Daniels. I would not consider anyone that does not have stocker experience,….the total seal rings are just so expensive these days ….

I agree about the rings. The place you mentioned is the one that built the engine...10+- passes ago. I found out Valve springs only had 110lbs seat pressure after 2 sets of valves, 1 camshaft repair, new cam bearings, new lifters, new correct pac springs I finally got that part right. Now I find it has well over 20% leakdown on 5 of 8 and 15%+ on the other 3, oil on top of pistons, etc. I personally have not dealt with them, I know alot of people have and had good luck. I bought the car with this fresh/new engine in it and have the bill from their shop

Sounds as though you may be dealing with a production block. Is it ? …is it filled ? 305 blocks are notoriously soft …

Yes it is and Yes it is lol. I probably will just take it back to him. I know stuff happens I don't put blame on anyone

I have seen this happen too many times over the years with production 305 blocks. He or anyone can hone it again but chances are very high that it won’t seal. Bow tie blocks /dart little M blocks are the only remedy to this situation.Unfortunately no one will sell their performance blocks. Another option would be to sleeve a 307 or 350 block. That would be a viable option. To continue to spend money on a production block is not very wise. All in all, I do wish you luck with your racing endeavor …

Re: Engine hone question
 

The TS rings are too hard for production blocks typically, and no the hone won't fix it properly regardless of what TS says. More RVK in the hone surface will help, but then you're creating unnecessary friction.
Mahle's HV385 top ring is the best choice for any block, production or aftermarket, if your bore size, width, and radial are available.

Good Luck

Check the oil ring tension. If it is too light it will pump oil like crazy. Do you have oil in the intake manifold?

I would get in touch with one of these guys, they may be able to recommend a couple of shops as well as tell you how you should hone the cylinders.
