Yesterday a young lady brings me a hurt 440 out of her expensive 70 resto mod Charger that she recently purchased. The engine has under 400 miles and suffered some major damage because whoever built it missed the mark on the details. One clearly missed detail is a rocker arm spacer on the...

On my own car, the 69 RR with a 426MW short block, 915 heads and an OEM iron 6BBL setup, I have logged about 10,000 miles so far and not so much have turned a screw once I sorted out the center carb. For anyone interested, my combo is mild but it makes very good power for a street car that can...

Just seeing a few options and wondering if anyone has experience with some of these new units. Years ago all we had was the OEM power lock 4 pinion carriers that were not terribly hard to find but now it seems many outfits are making them. The cone units of old would like to drop the spider...

Hey there, it's been about 35 years since I been into one of these (mostly 4 speeds lately) and I'd like some input on what may be going on here. Pretty sure I have all the parts installed and correctly but I have a lot of input shaft end play. Like a shitload. Tail shaft is in and tight with...

Building a low block 426 for a guy and so far the compression is calculated to be ~9.4:1. .060" over (4.31") with 3.75" stroke and nearly zero deck piston with valve reliefs, small bore chamfer, comp gasket. I'm trying to target about 9.8-10:1 to keep it CA swill friendly with aluminum. If...

This is on my 69 Dart GTS convertible. I stopped driving it a couple of years ago because it was gushing fluid from what I thought was a converter seal or something but didn't look into it until recently. The car needed other work so I just parked it. Looking into the leak issue more...

Also weight in grams. Summit has no answers and I can't find anything on the manufacturer web site. I'm thinking this VMS-75 alloy is a high silicon type and will run close to the wall but I'd like a tolerance so I can accurately measure my result. I have a 383 I want to hone and rering but...

Long ago it seems I read that these were installed in the 999 (beefy 904) that was in Cordobas. Any truth to that? I have a big block 727 tranny going together now and thought I'd slip one of those in for some low end grunt with 2.94's. So a few questions: Is there a cheap and easy...

Does anyone have an idea what compression these are from these pics? They are for a stock stroke crank. Thanks. They are for sale by the way, but I'd like to have an idea what they are. .005" over.

Long ago when I had the 4 spd in my 68 RR the clutch began to chatter so I pulled the tranny to investigate. I was running the Borg and Beck pressure plate (OEM style used on MoPars) and found the three fingers to be at various heights. It seemed obvious to me that was the problem so I...

I have wondered about this for years if the 426W that just went in my 69 RR is a max wedge block. I had this engine since the 80's and got it with all the MW stuff (cross ram, heads, early 300J rods, and a bore notched block). The part that is curios is the cast number does not correlate to a...

So here I am working on 68 Sport Sat's 451 and this sore thumb pops up. Close examination shows the crank was ground AFTER the ding so there are no high spots. The defect is a good .020" deep and you can get an idea of the area from the pic. It is also toward the edge of the rod bearing...

My buddy has this slick gadget made by Innovate Motorsports that uses a heated O2 sensor and converts the sensor mV output to A/F ratio in real time. It also has the ability to record and save tons of data. The unit is powered by the cigarette lighter, or at least it was after I fixed the...

What's the scoop? I saw a set of new castings for sale but have exactly zero experience with them. Junk? Good? The guy says they have hard seats but I don't see the blue ring around the exhaust seat - meaning evidence of heat treating. They look like a production late model head to me but...

I have a factory 426 HEMI block and the #1 and 5 main caps are very loose so I'm thinking about going with an aftermarket cap as a solution, but from who? Anyone have any experience in this area? Or does anyone have a junk HEMI block with good caps?

Any of you guys work on these or know anything about them? I have a friend that has a 2005 and the cluster or input shaft bearing sounds like it's ready to fly out of the case. Also it pops out of 4th. What kind of a nightmare can I expect taking it out? What special tools are required...

Just did a little research and ran across them http://www.summitracing.com/parts/SLP-L2355F30/ Somehow I thought they were gone forever but doesn't seem to be the case :hello2:

I've been looking at expanding my tool collection for rear end related stuff so I looked up Miller Tools, who is the factory tool supplier for MoPar dealerships. While searching out the 9.25" tools for my 02 Durango I noticed familiar part numbers so I got out my 68 Plymouth service manual and...

Today I was working on my 426 wedge for my 69 RR and came across this little issue that I thought I should throw out there. While I was installing cam bearings and checking the cam fit I noticed an interference with the timing chain sprocket while turning the cam. Closer inspection revealed...

Just took apart an early 18 spline for my 66 HEMI car and found this mess. I didn't pay much for the core so I'm not complaining, but geez, this is pretty screwed up!! Fortunately I have extra parts and can get what I need from Passon to get it into top shape. The input bearing cage broke...
