I made a set for me and another member, I have 2 sets left. These are one piece billet aluminum ( not an extrusion with bolted on angle plates for mounts) I have had these hard black anodized and can engrave Syclone or Typhoon on them. (see pics) These are a unique design as I designed the front...

Awhile back I had a website bookmarked where they found a brand new Syclone crate motor they un-crated and had detailed pics of it. That computer died and I lost the link, does anyone have the link or the pics??

I am rebuilding the Hydroboost from a 94-95 Astro Van, the accumulator dump/check valve did not have a check ball in the plastic piston. I saw a Youtube video where a guy left it out and the system over pressurized, destroying the Hydroboost. In the comments of his video a person did not have a...

I am going to run another batch of these, price needs to be bumped to $325 which includes the TCI button. You will have a choice of either an Aluminum or Delrin button. ZSKI is also posting this on Facebook as I don't FB. I will also be taking deposits this time round. Here is the link to the...

Looking for original style Syclone key blanks. B45-H Door B44-E Ignition Thanks

I have been asked if you are suppose to use the extra bracket that comes with the Energy Suspension Transmission Mount when installing one of my adapters. The answer is YES. The mount is a 2 piece design and when tightened together the plate compresses into the mount for support. Without it the...

There seems to be an interest in making some of these, I will start this interest thread and see what we can do. There will need to be a price increase of $50 over the 4L80E ones do to the fact they are 1/2" thicker. This is to cover the extra material and machining cost. I have only ever made...

Here's a couple pics:

Just want to let Admins know I received a PM from a Guest "CBETAsex" in Russian, It was sent out to multiple recipients.

I have done this mod before with weld, after struggling with bad castings and warping I will no longer attempt welding them. This is what I have come up with as a re-placement. It is not 100% perfect but as close as we can get, there is no way of matching a cast aluminum color to billet...

Need a Stock Upper Intake, let me know what you have. Thanks

I was asked to make a Custom TH-400 adapter just like our 4l80E adapter. The only differences we found was the locating diameter to the Transmission and that it needed to be 1/2 inch longer. I decided that I would take pics as it was being made and would share them here so you can see what it...

There is a L with an arrow and an R with an arrow, I assume these ends go into the torsion keys and the arrows are the tightening rotation correct? This seems to make the most sense to me. I question this because I have read conflicting opinions on which end these markings go . Thanks

GM part number 15637669 is discontinued, it is the seal for the 90' elbow at the oil pan. Anyone know of an alternate part # or seal that works? Thank You

Took my transfer case apart to put my 4L80E input shaft in and found this rubbery material in the planetary gear area. Could this be the viscous coupling failing? I read this thread I am thinking it could be the VC fluid leaking out?? Or what else could it be...

Sold

Need help estimating HP and Torque with my build so I can order a Torque Converter with the correct stall for my 4L80E. Also advice on which Torque Converter would be awesome, do I need a $1,200 Circle D Stage 1B or is that overkill? Truck will be 90% street driven with occasional trips to the...

I have made 4 more adapters, 1 for me and 1 for another member, so there are 2 left for immediate sale. Here is a link to the original GP: http://www.syty.net/forums/showthread.php?t=93554

Anyone know what this bracket is for? Thanks

I have an Edelbrock water pump. Should the nipple coming out of the top of it for the heater core be straight or at a 45' ? The only one I have to go by is Len's truck, which is a 45', but he is not running heat or A/C. I looked at the GN Northwest's zero mile motor and can't see where the...
