And that is the purpose of Import Duties, to level the playing field so that countries that: use child labor, abuse the environment and or subsidize export items do not have an unfair advantage. Now if we only had a Federal Government that placed a priority on protecting its own citizens…..

I don’t know about v8’s but for slant six motors the FSM specifies that the oil pick up is an interference fit to the oil pan floor. My assumption is that mopar v8 engines of the same era would have the same fit requirements for the oil pick up tube. My ‘engineering’ guess for the interference...

I have beehive springs in my motor. Less weight up top, resolves clearance issues, what is not to like?

I put a set of the B3 rocker shaft spacers on the built slant in my 68 Barracuda. The motor has valve stems .090 longer than stock and roller rockers. I did a before spacers and after spacers comparison of the roller travel across the valve stem tip and the reduction in travel was remarkable...

Possibly they Concerning pistons, cast, hypers, forged will all have different clearance requirements. I know one can assume that the piston mfg made the pistons to a nominal size, but I would rather not be guessing on something as critical as piston clearances. Wonder what kind of finish the...

Your motor do it your way, but for me things are perfect when things are done the way that I ask them to be done. And I always tell the machine shop how I want the work to be done. And when I say I tell the MS how I want the work to be done, what I actually do is, ask plenty of questions, dig...

What you mention, timing-AFR-idle speed is about right. But the process can be iterative, meaning that you may need to go back and slightly re adjust the timing and - or AFR to get the idle quality that you desire.

The space present around the top of the piston down to the top ring is included because it is there. The piston does not expand from combustion heat to close up that space. It is a trend for OE and some aftermarket pistons to move the top ring higher on the piston to eliminate some of that space...

Using standard gasket sets, RTV and Permatex High Tack adhesive I have build many motors with out leaks. And they will come apart with out major issues. The keys to leak free engine building are: clean - flat mating surfaces, quality - defect free gaskets, correct torque on fasteners, and...

Have you disassembled an oil pan or valve cover that was glued to the crankcase with that Right Stuff gasket maker?

I also thought the video was good, factual verifiable info,, with the exception of the lawn mower test,, not sure what he was trying to prove but a 50 50 mix of new and old STP would be so thick that it would not provide any kind of ring seal. I don't recall STP ever recommended a 100% STP...

No inspections in Indy because nothing would pass, the bad roads here beat the heck out of the cars.

I was working through a rear mounted turbo set up a few years ago and sketched up a plan to use one of the sub frame connectors as the pressure side delivery passage. I have since moved on to other projects but I still think a rear mounted turbo has advantages: weight distribution, packaging...

In plating copper sticks to steel really well. The over size or out of round condition is in the thousands, so the plating is very thin. Try peeling the copper plate off a penny, or bite into a penny, you will get the feel for how well copper sticks to steel and how hard a thin copper plate is...

Was not an issue with the weight, the bore size was too big or out of round.

Anyone else notice the OP is changing oil on an engine that has ‘not ran in about 4 years’. Ok, is this action being done as part of a plan to start the motor? Or is the oil being changed because it’s been in the engine for about 4 years and the engine will continue to sit?

I'm sure that the collective brain trust here has far more experience than me though. Probably not.

I have seen large bore pistons, pistons with the diameter of a 55 gallon drum that had a hole drilled and tapped in the center. Those holes are used to thread an hook into so the piston can be lowered into the cylinder using a chain fall. Why a small bore piston would have that is beyond me. If...

spring pressure with the valve closed is the attainable spring pressure at the installed height. Typically in the high 2 digits to low 3 digits Ft lb. Not enough to straighten a bent valve stem. But I agree, with a worn guide or a very slight bend in the stem, it would be possible for the stem...

Post # 50 # 51 mentions that valve spring pressure can pull slightly bent valves back flat against the seats. What? No way an closed valve with spring pressures in the *** Ft Lb will pull a bent valve head / stem flat that has steel tensile strength in the xx,*** Ft Lb. If there is wear in the...
