What issues did you have with them?

They would probably recommend them with the factory retainers. Its the crow retainers that have an issue not the springs.

The best springs by far are Atomic.

Crow valve springs with Crow retainers are not a good combination. There is known issue with them, to get the correct spring pressure they have recessed the collets further down into the retainer. This is a big issues on the exhaust side as the valve stem is slightly shorter which brings the retainer higher which then makes contact with the rockers arm. I have called them about this and they played dumb. Have seen this so far on 7 engines so far.

Why remove my add them? Put my add backup and ill pay for it when you fix it..

I listed an add and put the price as $1 as I could not make payment with PayPal getting the following error Warning: in_array() expects parameter 2 to be array, null given in /home/xr6turbo/public_html/forum/admin/applications_addon/ips/nexus/sources/gateways/paypal.php on line 172 Warning: in_array() expects parameter 2 to be array, null given in /home/xr6turbo/public_html/forum/admin/applications_addon/ips/nexus/sources/gateways/paypal.php on line 177 Warning: in_array() expects parameter 2 to be array, null given in /home/xr6turbo/public_html/forum/admin/applications_addon/ips/nexus/sources/gateways/paypal.php on line 172 Warning: in_array() expects parameter 2 to be array, null given in /home/xr6turbo/public_html/forum/admin/applications_addon/ips/nexus/sources/gateways/paypal.php on line 177

What problem are you having?

The issue was in the oil pump in the auto finaly found it and its now being fixed.

This is a good video to show what's happening http://youtu.be/YEfqKoilLkI

The thrust was not lacking oil, the failure was so sudden and brutal that it had to to be something else. The motor was fine with the 4 speed behind it for nearly 1000km while I was runnig it in, but when the t400 went behind it with in 500km it was gone. The face of the thrust bearing facing the rear of the motor was almost completely missing, the face of the crank on that thrust was also destroyed. I would of said it was a thrust issue but the billet backing plate on the rear of the oil pump had so much presure put on to it that the crank almost went though it and also destroyed the oil pump gears as well. This was all force being applied from the rear of the crank from the back of the engine. The auto builder, converter builder and my mate the engine builder now all agree its an auto related issue but no one wants to take responsibility for it. I had a talk to Peter Veersma from Welshpool automotive in WA who I have been told is one of or the best auto builder in Australia to have a look at it. He has been more than helpfull and I am now in the process of getting the auto to him and have also contacted a lawyer to sue who ever is responsible as they have had multiple chances to fix it...

This time around I ran a cap and block thrust 360deg. Clearances were checked and double checked. The atomic flexplate has some negative clearance it sits 1.4mm closer to the converter pads but even then there is enough conveter to flexplate clearance (4mm). If there was not enough clearance the pressure from metal expansion would of broken the transmission pump gears as well. We have gone down this path and that's all been checked and double checked by TCE as well at my mates shop. We now have another transmission builder looking into to it and also spoke to someone who had a similar issue yesterday in WA and one guy in QLD. It's not the atomic flexplate that caused the failure. Also called Neal chance racing in the US they have a theory of what it is but I wont say until I have confirmed the issue with them. The automatic has also been checked with in an inch of its life and is being dissembles and inspected piece by piece again especially the oil pump. We are not new to this speed thing, been around the traps for 20 plus years so in saying that everything is being checked from the crank back with a fine tooth comb.

Hey all who here is using an atomic flexlpate?After the failure of my first engine we think we have pinpointed thw issue. AtomicG6e also had the exact same issue as me which was major thrust bearing failure. I have a turbo400 and he has a powerglide we both have atomic flexplates. Flexplates are called flexplates for a reason they are designed to flex under torque converter load. So who has an atomic flexplate and what transmission have you got behind it?

Organise your auto first, then when you have decided what auto your getting order the right overdrive unit to suit the box.

Try ALS raceglides in NSW or Protrans.

I did it in mine you have to buy 2 sets of main bearings, like you said the sets only come in 180deg thrusts.
