Lifter guides....
Has anyone ever encountered wear marks in the top side of the lifter guides? I'm in the process of rebuilding a '68 327 to drop in my '92 RS and noticed them. I tried to post a pic but it won't let me. Any help would be great.

Lifter guides???
Do you mean the bores the lifters ride in? Lifter bore wear is not uncommon. Can be expensive to fix, though. Not many machine shops are equipped to bore and hone lifter bores.

I wish I could upload a pic. Its not the bore itself...It's above the bore. Hard to explain as I've never seen it before. It's a little wear above the bore where the lip is...

Re: Lifter guides....
What lifters, heads and rocker combo are you running?

Re: Lifter guides....
I bought the engine from a buddy of mine. When I picked it up he had already pulled the rockers,push rods,cam and lifters so not sure what was in it being the guy for some reason tossed them. I have a New cam and lifters that I plan on putting in it. Which is an Edelbrock 2102. Came in a set with flat tappet lifters.Still have to get the new rockers and push rods. The heads are the stock camel hump heads.

Re: Lifter guides....
Its hard to tell from your picture what wear you are talking about. Honestly, it all looks normal to me. I have a 327 block in my garage, I can go look at the lifter bores and take a picture for you.
Remember, the lifter bores on a roller block like your 92 would have had, are different. There are no dog bones, so the lifters can rotate. Pushrod alignment is done with slots in the heads, or pushrod guide plates, and the rockers are non-aligning. It is all very different from the way a roller cammed block looks.

Looks like a machining operator wasn't paying attention on the 1st 3 holes that day it was made.

Re: Lifter guides....
Can you circle the area on your picture that you are specifically worried about?
If you are talking about the different levels of chamfering, that is very normal, in the early 60's casting was not what it is today, so you had some lifter bores heavily chamfered, and some got none.
If I am completely missing what you are speaking of (which i very well might be, haha), highlighting where in the picture you are worried about might help.
