Just looking for data points here. The question is what is the maximum acceptable lash closure rate rate (or lobe velocity) for when a solid lifter lash is taken up on the valve opening. This would also the rate for when the valve closes.) This would be measured in inches per degree. I have a...

Wow.. just saw that yesterday. Hertz filed for Chapter 11 bankruptcy about a week back. Chapter 11 is for re-organization protection. I have done a ton of biz travel for 35+ years, and Hertz was always there. So much for being a Gold Club member LOL Looking back into rates for car rentals in...

For those who want to be informed and want to understand the 'why' of the measures that are being taken, and can be taken, to best control the corona virus, here is an excellent article that brings it all together. This is offered to help understanding; it is a bit of a long read but VERY well...

Not Mopar, but I figure I'd get some decent thoughts here. I have some oddball 4-banger Arias forged pistons here, and the pin bores are at .912". Got some JE 2 layer spirolox that fit the .042 width of the pin lock grooves just fine. And the .927" diameter sizing of these spirolox should be OK...

Just as a matter of curiousity.....I was installing helicoils (in a new billet AL flywheel for the pressure plate bolts) and had to run one helicoil all the way through and out the back side, because I missed a burr in the threaded hole and the helicoil was not sitting in the hole right. It was...

Hey all, I am taking a long shot that someone in this knowledgeable crowd might have some old Arias piston experience. I have a set of old Arias forged pistons that are probably 15-20 years old, that I am planning on putting in a block for street use (not a Mopar, but Opel 1.9L). I have had...

Wanting to see if any of you guys know of a shop that can offset grind cranks, re-harden and balance. Mid-Atlantic preferred but can ship to a good shop. Not for Mopar..... Opel 4 cylinder 1.9L forged crank. I plan to offset grind the rod journal to move center outward by .125", for .250" longer...

This is not for a Mopar but I have an old Norris cam in good shape but can't quite decipher all the stampings..... Pix attached. The question is about the 'SH' designation. From what I have been able to find about the Norris cam world, 'S' for solids and 'H' is for hydraulics. So is 'SH' for...

Not a super important topic.... So I was on another auto forum (where there is less motor expertise than here), and in response to my comment to not ever put used lifters on another cam, this was posted in support of re-using used lifters on another cam. "The reality is that you do risk a...

Have been reading about a problem had with one of these new Li Ion car batteries over on a another forum. One caught on fire in a car, and if you read down in this thread, you see the OP conversed with the mfr, and was told that it was probably (and in general can be) caused by jump starting...

Not a good idea to go driving on the beach as a hurricane approaches. This is supposedly live from Myrtle Beach:

I saw this posted on another automotive forum and it just floored me..... thought your guys would appreciate this part of a post by a guy who thinks he know what he is doing: "I didn't mention all of the attention and tests that the tuner gave to cylinders 1+2. He showed me that cylinder #2 was...

Built a 'car corral' to make the County happy.... thought I had put in margin to fit 2 certain rally cars in side-by-side. In the process, those posts got moved a few inches.... glad they did not get moved any further! Had to take the mirrors off of the All-Trac LOL

The 2nd segment explains it all.... when they fall off, they can't get up....

I ran across this site that I figure the FABO crowd would enjoy. Mopar actually had quite a history in rallying in the US/Canada and had parts and support for the Colts and Arrows for many years. If you have an old Direct Connection book, all those sections for the 1.6/2.0/2.6l were all directed...

Another silly question: How much can be cut from the OD of a 2.02" valve head? Similarly, what is a good minimum width for the seat for moderate street use? The reason to ask: I'm trying to stuff AL heads onto a bored 273 block (like Promaxx or Edelbrock) and am seeing a possible issue with...

I never paid attention to this before, but with the oil pressure issues reported on this forum, I begun wondering how much lifter bore wear is a factor, that folks are just not aware of. So I measured a 273 block here; this is an approximate 100k mi engine, original, with cylinder bore wear no...

I tend to check my German made dial caliper regularly against micrometers and never saw it off more than +/-.001. But was measuring a 1.125" OD on a needle bearing assembly and kept getting .003" small. Compared with a vernier caliper, and 2 micrometers, and darned if the dial caliper was not...

I have read up in the Clevite-Mahle catalog about their anti-wear coatings option on the 77 series bearings; sounds nice. But paying $200 for a set of the -K suffixed mains for the intended use was a bit steep LOL. So a set of MS540H and CB481HN bearings (early LA's: 273 and 340) were ordered...

Just an update from this prior thread on weighing rod ends with a low cost home shop jig: Low Cost DIY Rod Weighing Setup A triple beam mechanical scale has been tried in place of the cheap electronic scale, and STILL showed repeatability issues related to side loading on the scale. This...

Ironmike mentioned it being winter and his brain working overtime on gearhead stuph.... same thing here LOL Dartfreak75's long decision making process led to this little project, and we've PM'd back and forth on solutions. He provided some of his 318 piston-rod assemblies for weighing to get a...

FWIW…. Pishta and I have been setting up low cost, home-shop weighing equipment for big and small end rod weights. This is a summary of one setup that is simple to build and repeatable. It is not the ultimate in accuracy but will measure end weights to a few grams tolerance, which is around 10...

It's thinner than I thought at the bottom of the cooling jacket in a couple of SBM blocks checked, while planning some bore notching at the bottom of the bores for rod bolt clearance with a stroker crank, like pictured in this article: This 436ci Small-Block Mopar Makes Big-Block Power On Pump...

I'm working on a pet project, and need a few 318 piston pins, to see if there is an easy way for anyone interested to save some $$ on a basic 318 build. If you have a few laying about and can spare them, PM me. I'll pick up the shipping tab. Tnx!

FWIW...... Just another of those little surprises. Got my 2nd set of SCAT I beam rods, PN 2-ICR6123-2124. When I placed the order, I requested that all the sets on the shelf at Summit be checked, and could I please get the set with the lightest big end weights? Well, they very nicely complied...

Nothing earth shattering here, but this was interesting and also perplexing: As part a little project to modify pin weights, a spread sheet was set up to compute wrist pin weights from volume and material density. EDITED to correct for a spreadsheet error. The first check of this spreadsheet...

If you have not spent any/much time in WY, you may not appreciate how windy as it is in some parts of the state. Overall, it has the highest average annual wind of any of the US states. I like this article; the 1st pix is a priceless and humorous indicator of how windy it is there. Wyoming...

For anyone interested, as far as a data point for the even-ness of factory balance work, all 8 pistons and rods, etc., from a '68 273 were disassembled, and all the individual parts weighed to compute the corresponding bobweights, including big and small end rod weights. There are the original...

Having one of our every 3-5 year tree-bustin' ice storms on Afton Mtn in VA, with almost 1/2" of ice on everything. Road's blocked right now; generator and wood stove going. Had a mature oak tree break 15-20 years ago in the front yard, right in the trunk, and it sounded like a howitzer going...

I think I know the answer.... but thought I'd ask. Any aluminum heads out there with 1.92" intake valves? The reason is to to put a set on a slightly bored 273 block, and the 2.02" valves may require too much notching.
