i can tell you any thing you want to know .if he is only leaving .003 in he may not... less he boring with deck plates on . on some engines i do bore them with deck plates on then hone the bores if you do not do it this way then i leave the bores .004to.005 under size deck plates can cost up to $600+ so less he is doing alot of one type of engine the cost is a big factor i use them on all chevy s and sbf and harleys and you should be no more bigger on tq plate then 100 over bore size

Here is a lower ranking view point from what you have said---IF HE LEAVES .003 when boring, he probably uses a drill driven hand held hone to finish the bore----Does he have a Sunnen CK10?????

IF HE CHECKS THE ALIGN BORE with the equipment he has AND says it generally doesn't need it----He doesn't have equipment for align honing---the words from him are the words generally said by machine shop persons would would like to have this equipment but don't--
As a older than me guy once said---there are those who have the equipment and there are the ones who say its not needed but wish they had it!!!!

And, please, I'm not saying he doesn't---

I'm pretty sure he won't have the deck plates. On the Olds 442 forum they say that most machine shops will not have Olds deck plates due to the low numbers they would do (compared to, lets say, a 350 Chevy) and the cost is prohibitive.

As for the line boring equipment, he does have that and, if needed, that would cost $ 150.00. I think he was just trying to be honest and not sell something we might not need. When he wrote down his prices for the various items he put a question mark next to the line boring and said he would know if it was needed when he checked the straightness. I liked that he did that because the other machine shop guys I have used in town always just went ahead and did the line boring automatically. Looks like this guy isn't trying to sell me something we might not need.

Another thing I liked about him was that he suggested putting hardened seats on the exhaust valves when we have the heads done. The other machine shop said it was too expensive and not needed on an engine you don't use as a daily driver. That concerned me as the cost he quoted really wasn't all that bad.........$ 10 per seat labor and $ 8- $ 10 for each seat. Works out to about $ 160 for the 8 exhaust valves. He also said he has no problem with us bringing in parts we buy elsewhere, like the Comp Cam valve spring kit. We want to get the kit Comp Cams recommends for the H280 cam in this motor, and I want to get Perfect Circle seals for the guides.

Here are some of the prices he is quoting, which I think are reasonable:

Clean block.........................$ 80

Line hone (if needed)............$ 150

Bore and hone block.............$ 144

Install cam brgs...................$ 35

Brass freeze plugs................$ 30

Deck (mill) block..................$ 100



All in all, not any more than we have paid elsewhere. Today I am going to take Dan out to meet him since it is his car and motor, and he can make the decision if we want to go here or take the drive to Sarasota instead.
