Frank On the V-8, the oil holes are drilled through the teeth around the perimeter where they mesh. |

The well placed epoxy on a new clean gear will fall off soonafter because of the various harmonics that the engine goes through, eventually ending up in your oil pick up, main bearings,ect....A simple and effective way to stop shredding gears, is just to drill th 1/16 hole in the plug. A tried and true experience through hundreds of rambler engines we have rebuilt from mild street to all out 4 and 5 second cars.

Red, I have never used any of the modifications you speak of and I use aftermarket cam and distributor gears, I wonder how any of my engines are still together? If the runout on the pump shaft hole is worn out and .0035" how will more oil help? If there is a problem with getting oil to the gears, I guess your band aid idea would work,... but I'd rather fix the problem
Also the oil pump with more teeth,,, How are you getting more volume with more teeth? are the gears larger diameter and you bore out the pump cavity? if not, and the gears are the same size and just more teeth, the teeth would be smaller(less oil squirted more times) so how would you get more volume?
Are you new to HLR ? Most of us have heard of Herman I have had experience with Herman's heads and intake and while they performe well they have lots of issues that need to be dealt with to get them there. I spent 90 Hrs on my heads and intake. 10 valve guides bad out of the box on raw heads, looked at a set last week with the same issue sent the buyer for Indy SR's instead. I hope you are working on QC over there
When I asked Herman how he was getting 340 CFM outta his heads @ .700, he told me that was at 1.000 lift not .700
Don't get me wrong, I love my HLR heads as they flow 306 @ .600 and 323@ .700
But bolt holes taped into the water, missing valve cover bolt holes, header bolt holes not in the right places...
Flame me if you guys want, but these are just MY experiences, your's my vary

Hey, dung talker! I think I know you.I recognize the bad additude. If you let Herman assemble your stuff for you,you wont have those issues. Bolt holes sometimes go into waterjackets,is this your first engine?If you got a bad part ,send it back! mistakes can happen anywhere.
As for myself,my Herman Lewis built engine is the fastest AMC at my local track.See you there dung talker!

Installing any kind of higher flow oil pump gears shreds the stock gears quickly. The OEM AMC pump can make enough volume for any RPM if it is in good shape. The main issue is drainback as Herman well knows. Drilling the hole in the front plug more than oils up the back of the large timing gear it misses the cam gear completely and it fills up the timing cover with oil. This is the result of that modification and really is not ever needed for a higher RPM AMC engine. The aftermarket camshaft gears have 4 oil lube holes just like the factory camshaft gears but what is happening right now is that their are too many hardnesses and too many mfg of gears and nobodies matches the OEM spec or works well with each others.
I dont know why you would say he has a bad attitued when he couldnt get good parts and his flow numbers werent correct. He was told one thing and delivered another and after all that work he has a set of heads that he could have saved money on just buying a set of Edelbrocks....why would someone want a set of Herman Lewis heads when they flow a hugh number at a camshaft lift they can never use? Your not talking to a bunch of spring chicken AMC'ers almost all of these guys have been messing with their motors for 30+ years. I understand it must be exciting working with Herman and I personally like the man himself he is fun to talk too but I can tell you from experience that spouting experience and having that you "Come here and sit under my wing...just trust me" attitude doesnt go far in the AMC world
Sorry if I came off salty but I take alot of pride in helping dispell the myths on modifications and un-needed parts.

As difficult as it is to get many AMC'ers to open the wallet and buy a part it should at least work when you get it.

Edelbrock heads ? are you not aware that edelbrock heads have smaller valves than stock? Herman has moved the intake valve over to allow for 2.125 intake valves.In drag racing ,bigger is better.Period.Its true there is some fitting to get them set up ,but it is well worth the effort.Of course,the power level is well beyond what the rest of the drivetrain can stand,so you need real racing parts to go with it.Herman is a racer, not a street car builder.
Like I said before,if you recieved a bad part,send it back.He will make it right.But he`s not God.We have all made mistakes,right?

I imagine Bubblefender is talking about on the street. But even for racing- being more efficient is more important than simply increasing valve area. Flow is more related to velocity - those huge valves- particularly at low lifts- are harder obstacles for the air to get around. Better that the port shape, valve edge and stem contours promote flow than sticking a bigger trap door over the seat.

But Hermans heads flow better than Edelbrocks.Add the larger valves AND larger ports, they are a better choice for wide open. The question is,how quick do you want your car to be?11 or 12 seconds with the Edelbrocks,10 or even 9 second quarter mile times are possable with the Herman Lewis heads.You need to increase the size of everything else the air flows through to get the most out of the valve size increase.For example,1050 Dominator ,HLR intake,HLR heads,1 7/8 Hooker super comp headers.Edelbrocks are easier,but they are more of a street thing.Thats cool too.
