440 block pics and drilling

[Steve DeTar]

The 6" reamer, 1/4 drive, which is High Speed Steel........AP HS 5-01

Hopes this helps.  Also on the drilling, if you have a 90 degree countersunk, 1/2 wide, it will really deburr the holes real nice.  It also helps get the reamer lined up in the center of the hole.  Just don't go crazy with it.  When it's all put together, it is about 10" long.

great tips now we just need someone to stick it to the top so its not lost the next time someone needs it

Very cool gentlemen! Which would you choose the cobalt one?
Mike

[Steve DeTar]

I was using a High Speed Steel reamer in the pic's.  If you are going to do alot of blocks, maybe the cobalt will last longer.

I asked them about the 4" arbor, and they suggested thier part # 3109A71 which has a '2-flute countersink' What does that mean?
Mike

[Steve DeTar]

I'll post some pic's of the countersink I am using when I get home.

Mcmaster car (part # 2975A42) 9/32 cobalt reamer. (# 3109A71)4" extension. These are the parts I ordered. I'll post more when they come in.
Thanks, Mike

[Steve DeTar]

Look under high speed rotary files while you are there,  these are the ones I use they too have a 1/4 shank you can put in your drill

(# 3109A71)4" extension.

This is just a 4" extension, no collet.      I need to know what style of threads are in the end of this to buy a collet? I found a really short one that takes 1/4" drill bits. It has 1/4-28 threads. Do you remember?
Thanks, mike

[dusterdood]

1/4-28 threads in the 4" extension. I ordered the collet I need. Now we wait!

    hi steve,

[dusterdood]

That's a cool pic! Here's a picture of the 4" extension. What area would be an issue to get to #5?

[Steve DeTar]

That is a little diff than the one I have.  Is their a 1/4 hole in the end of that?  We have some like that at work that we use also.  All thats required is locking down the set screws so the reamer won't turn in the extension if you hit a hard spot.

Just a remiinder to those who want to upgrade their oil system beside a 1/2 inch pickup.

If anyone wants to see what it looks like when a drill bit is used,pay the shipping and i'll send you a fully machine ready to assemble o-ringed 60 over block, with a brand new factory fresh broken bit pre installed inti the #3 main oil hole.

It's a bargain i tell yah....i'll even send the other half of the bit for no extra charge!

Oh that sucks! Haha

[mopfried]

We have a machine here at work that can burn that broken drill out. We use it to burn out broken drills and taps. Its kinda like an EDM machine thing. It has a electrode that is make from tubing an it burns the center out so the drill or tap can collapse. Can you possibly weld something to it and work it out? How much to ship to 43123 in OHIO?

What was the part number of the collet you ordered?  Was it from McMaster-Carr? 
I found the reamer and extension.  Can't find a 1/4" collet in their on-line catalog.
Thanks in advance,
Robert

[ABRASIVE]

I would ship it to you in ohio but after trying to get the bit out by tapping on it with a hammer and puch to loosen it up..........

I got pissed off and smacked it with the hammer, the block is beyond fixing now.I am still not happy about it.

Nice job Steve. Good attention to detail. With that said, and, I by no means am saying this to bash Steve, but, that mod is largely a waste of time. The mopar big block oiling is quite good. I personaly have built more big block mopars than I can count over the years, and I have never done this mod. I have built everything from 400hp enhanced stock type engines, to 850+hp naturaly aspirated stock block engines, to 1000+ hp blower and nos engines etc, and, never had a crank or bearing issue. NEVER. If you set your clearances right for the application, and use a good pump, there is plenty of oil getting there. The only oil mod I do, when I use a screw in oil pick-up, is to radius the 90 degree turn, the oil makes, from the oil pump mounting pad, where the passage is drilled into the block, then, the oil passage that feeds the pick-up, thats drilled 90 degrees and intersects each other, I radius that corner, so the oil can "turn" with out getting all turbulent there. Up to roughly 700hp, and 7000 rpm, I even use the stock sized pick-up, with ZERO issue, ever. After that, I use either a single, static pick-up external line, or, a dual line, with swinging pick-up.

With that said, if you want to do the mods, then knock yourself out, you likely won't hurt anything, but it really is unnecassary. Long, skinny drills and reamers, break REAL easy. And, if you aren't careful, and one snags, or catches, they snap without warning. Again, I am not trying to downplay Steves work, but, I thought I would give my opinion

Frank I don't use drill bit's, they break too easy.  Lot of these oil mods were passed down from old super stock racers from the 60's and 70's,  Herb McCandless, a friend of my dad's.  Thanks

[bOb shingler]

and with that being said the only blocks/bearings that failed on me were the ones i didn't do the mods on, but i'm just a "back yard do it myself kinda guy" and every little trick helps me out.

X3 on the sticky reuest...

[dusterdood]

I couldn't get the collet from Mcmaster-carr. I found on line a company (tight fit tools), who sold me a threaded collet for $8 + $5 to ship. The phone # was (562)946-8444. There's probably a better way to get the pieces you need, but I'd already bought the extension.

Thanks much for the info.  Got it all ordered this morning. 
Let the fun begin!
