I'm sure Larry Meaux would be interested to hear how it's incorrect, not to mention all the professional builders that use it for reference. The problem with basing your whole cam selection on DCR is what I see as "squishy". I've seen more than a few threads talking about how people are...

I'd suggest not using that incorrect calculator on the KB site, that has really caused a lot of bad information on this site. Can anyone here tell me what RPM you use to figure DCR, and do you understand what DYNAMIC means, and why it's called DYNAMIC compression? I would suggest you buy...

X2 on Molnar, dealer for them myself. Tom was the engineer behind two other well known higher end mfg's.

Thanks Rob I've seen a few threads about valve covers not sealing or breaking ears off the corners of the BBM and the quality of the covers gets blamed. This is the real problem, the valve cover rails on the heads are never cast very flat and the covers snap when you tighten down the bolts...

I believe you :D The castings are never flat and some worse than others. Stamped covers can flex some and seal a little better. Cast or fab'd covers wont. For me it's a standard operation on SBM/BBM to mill the rocker rails flat so they don't leak like crazy. Only way to fix it...

Some guys try to use a ball mic and subtract the bearing shell thickness from bore diameter. Doesn't make sense to me but... Check the bearing at 12 & 6, as they get wider at the parting line to account for stretch/rods pinching tighter at parting line.

Bigger isnt always better, the port has to have the correct size and shape for the CI and RPM. You can't correlate the first set of heads you ported with making you go slower. Its about the correct shape,size and combination, and that includes the cam, compression, etc. That's like claiming...

That pattern looks a little wide IMO, like the shaft needs to be shimmed a hair higher. Whats the cam lift and the coil bind on the springs? Seat and open pressure? What wall thickness pushrods? I'd also check seat runout if they did a valve job. Most shops don't do that either and the seat...

Measure from the deck to the quench pad on the intake side of the chamber with a depth mic or a depth attachment for a calipers. Should be roughly .095" from the ones I have checked. The area at the lower portion of the chamber in this picture. The rocker rails are cast so poorly its not a...

X2. A simple examination of the plugs will tell quite a bit. Any oil on threads or the tips, or black in color? Fresh engine shouldn't have stuck rings, however poorly honed blocks wont seal rings no matter how much magic potion people tell you to dump in the oil. If the rings are sealing...

You have multiple problems- Block wasn't honed with a torque plate, preventing the rings from sealing, as seen in the ring wear patterns. Those bores move .002" with a plate on them, using up any effective clearance the piston might have had. and seen on the piston Along with being way to...

Has to be drilled by the engine assembler. A 1/32" drill bit is what I use, so it takes some care to do it without snapping off the bit. I use a Bridgeport to do it.

You don't need a guy that knows Mopar, you need a man who understands the dynamics of airflow as any good porter should. Take a 2.5hr ride up to Hays and talk with Chad Speier. He will flow your head and give you excellent results. One of the smarter guys around when it comes to heads. Take...

Well, honestly I'm not baffled, just seems odd you would imply there is no way possible to reference deck height or squareness when you obviously have the knowledge and awareness of how to do this stuff correctly. A simple process of indicating in the plate and a measurement to it does both of...

No. Your making the assumption the bores are perpendicular to the crank CL and to each other. This is production line machining that needs to be corrected. Not a single automotive machinists is going to take the time to mount an indicator to the boring head, and sweep the bore top to bottom to...

Crank thrust and cam thrust face are the two reference points, but unless you have a 4 axis mill setup for blocks, you have limitations. You can reference bores from head dowels, but tolerance stack is the problem. Most people that deck blocks float the block thru the mains on an adjustable...

I noticed that, Journeyman Machinist/CNC programmer myself. So you understand castings move around with heat cycles and have to be checked all over. What I see is some blocks will be less than .002" front to rear along an outer edge or centerline of the cylinders, but check an outer edge and it...

FWIW- I have a particular brand of TC that I use on a regular basis. Last time I ordered one for SBM it had too much slack in it. Problem was the root diameter of the teeth was cut .012" smaller than it should have been, causing the slack. Ended up using a Cloyes. Like stated before, use the...

I understand what your saying about "zero decked" but then again, that's what it refers to, Zero decked for that particular application. As for your underlined statement above, I'm a bit baffled. Its a simple fixture for older machines to set deck heights, and correct the 90° deck angles and...

Clevite H bearings are stamped upper/lower on the back side. Also the side toward the crank fillet needs to clear so it is obvious if you put them in wrong. They discoloration you see is normal. Just take a good look to make sure there is no thin spots with copper showing as some slip thru QC...

Your saying the Buzz has died down?..... Installed height of most beehives is more than what stock SBM's use, so that becomes the first problem. Cost is quite a bit higher , but well worth it in the right application. There is some that drop in but IH works better when you install Chevy valves.

What oil is in it? Keeping lifters in order is important, pushrods wont matter, unless there is a problem with one. Then you should track where that one was when doing your search for the problem.

Carb jetting will be based on what the plugs look like and mph at the track. Start with the standard jetting for that carb, nobody will be able to tell you what is optimal for your setup but the engine itself. Start with the stock plugs, Autolite or I prefer the NGK's myself. Timing will be same...

Plenty of factual info to be found with a little reading on how a carb functions, how A/F ratios are calculated, etc. I'm not here to hold your hand, I asked for an explanation based on your statement and facts. But instead I get insults like we are in 3rd grade. You stomp your feet when you...

I asked for an explanation of your statement, not if the carb was too small for his combo. My Engrish is fine, but your physics isn't even close.

Please explain how you come to this conclusion? What does the size of the carb have to do with if it runs lean on nitrous?

Alex has what he thinks is an issue with his freshly done heads. He's correct, he does. Why does he have an issue like this? Because of the process used. Suggesting to grind valves to non uniform length is sloppy work. The valve are different lengths, yes, but the difference should be on the...

I am looking thru the eyes of less volume, higher quality/rate, and that's what I stated when I said the Professional head guys I know use a vertical mill, not a rebuilder shop. And believe me, its not a matter of cash flow, as it is the money spent vs the return in quality. They are after the...

The different qualities of valve jobs and a good discussion on ways to achieve different/same results.

When you compare the spindle/Quill on a Bridgeport to a S&G machine, you start to see why guys use a vertical mill. Top of the line is a perception, using one is reality. I have the opposite view I guess, as a well optioned Bridgeport is a very accurate machine, and is far more capable than a...
