Gathering parts to put this 440 back together. I noticed it has 8519 Shim head gaskets along with the 8519PT1 head gasket. Is there a purpose for the steel shim/copper gasket other than to lower compression or shim up for valve clearance? My dilemma is that I cannot find the 8519SP shims...

This is a Hughes transmission and when I first got it it had a leak at the pump. But now the NSS switch is leaking from the center pin. WTF Is this common? Very weird why all of a sudden it would just start leaking. I resealed the transmission pan and installed a new gasket because I thought the...

He's working on a Yukon but the assembly should be the same. Video 1. Video 2. Video 3.

I installed this cam and lifters the a few weeks ago. It ran fine at first during cam break in. Was in it about 6 good minutes and then all hell broke loose and it sounded like ****. Tinny popping sound coming from the engine. I had JJ shut it down. He had already bought a new engine so last...

Guy I sold my 440 to wants me to build his original 383 Someone else started working on it but he ended up getting the engine back from the builder with just the bottom end put together with .040 over pistons. Anyhow he brings me a truck load of stuff. But the majority is either missing or he...

I was trying to fix the perpetual valve cover leak on the 383 I found out that one of the bolts was too short and not making it into the threads. So I pulled it out and stuck a piece of all thread in there to get the depth of how long the bolt was. Well here is where it all went south. Vice...

I installed a Lokar cable but the question is should I add a spring to pull the kickdown back to the I guess you could call it closed position? The reason I ask is because the kickdown lever kind of floats between a half inch where it doesn't really feel like its doing anything. I also get hard...

I have been working on this issue all day. The car is a 70 GTX 440. The car has valvetrain noise all the time. And I have been trying to trouble shoot the problem. Thought it was fuel starvation. replaced a worn fuel pump rod. Didnt help. Checked timing. Didnt help Checked plugs all looked...

My friend has a 440 with an Edelbrock Performer RPM intake the issue he is having is that the intake sits up about an inch and a 1/4 too high. What intake besides a stock 440 intake will fit with a 70 air grabber setup.

I have a 489 case. Not that I really care what the date code is but. I'm trying to sell it and the info may help to sell it. Here is a picture of the casting date code. I think its 8V12 I found several topics on this but the V is throwing me off.

Mike just bought a suretrac setup I will be pulling the 489 out today and installing the new 489 sure trac with 3:23's and a 7290 yoke. Today will be the first time its been on the road in almost 2 years. I mean other than taking it up to put gas in it.

I gave up on trying to set up this Suregrip. I put it all back together with crappy results. Gear whine off the throttle and both wheels wont even spin freely on the jack stands. So I found a completely rebuilt to my specs 489,suretrac and 3:23 gears on ebay. I called the guy in Loveland...

OK when the open 741 case was in the roadrunner the axles were ok. When I swapped out to the 489 with the sure grip I got the passenger side axle in with no issue. The driver side was a pain and ended up having to trim 1/8th inch off the axle. I have been doing some reading but Just want to...

I have just about everything I need to put the sure grip together. I am missing one thing that I can tell. If someone knows the part number or if they have a complete yoke with the I guess dust shield on it let me know. But here is a picture i took from this site and put a red arrow pointing to...

I had this bracket and it fits in the passenger side head. I believe it’s for a alternator relocation. I tried using the bracket I bought from a guy here but the main y looking bracket lines up with the head hole and the bottom water pump hole but it’s too short for the bolt that goes below the...

Ok Im looking into a set of lifters and a cam for my 383 as you all may have read in other threads... When I look at Summits site and a specific cam and lifter set it says lifters will not work in 67 back 383's Whats the difference between a 67 and a 68 383 lifter bore? Direct quote from the...

I recently bought a set of heads from another member here in a package deal Both sets of heads appear to have been rebuilt and both are very clean heads. I was measuring the valve springs with my micrometer. And the set I recently got have bigger valve springs but dont know if they are stock...

Well today I took apart my friends 383 HP and discovered that the rear lifter and cam lobe are wasted. I was told by the guy who built the engine that it was a stock grind Cam. My question is what is a good cam to get and still retain stock pushrod length and valve springs. Just paid for new...

Hey guys I recently picked up a 1966 383 but a couple exhaust valves were rusted off at the seat. I was looking for a couple of exhaust valve to replace these. I guess buying new would be the best way to go. But if someone here had a few that were not in bad shape and reasonably priced I would...
