More problems with my stroker project. My machine shop ordered ARP main studs for my 383 stroker but the studs for the windage tray were too short. So they orderd 1/2" longer studs but they are still about 1/2" to short. Does someone know if ARP makes a stud that is long enough? What are people doing to use the stock windage tray in a 383? Bending or notching for clearance or getting longer studs. The owner of the shop who ordered the studs is on vacation otherwise I would be asking him... and I want to finish before summer is over, need options!

 

I used stock bolts for the windage tray and used the stock pan. If I were you, i wouldnt use the stock tray or pan. I learned my lesson 2k later. Get a canton pan with a tray in it and you wont need the longer bolts. I know it expensive but is cheaper than spun bearings.

Just out of curiosity were you using a high volume oil pump?

I haven't heard of people having problems when they run the standard pump with an aftermarket windage tray yet but that could be because no one mentioned it I guess.
Let me know.
Thanks

 

Im not sure but i think it was a stock volume pump. It says M55 on it.

 

To answer your question yes I am using a HV pump. I have read the horror stories about HV oil pumps, but my machine shop set my main and rod bearing clearances about .0005 larger than stock nominal and they recommend using a HV pump. I called Melling and talked to their engineer and he recommended running the HV pump? Some points he made that I remember the HV volume is between 10-25% higher than stock with the average increase being about 15%. In order to increase psi in a given engine you need to increase the volume. The car is my fair weather car that will seldom if at all see the drag strip. I'm thinking it will be too fast to run without a roll bar and that is not in the cards for a while. I will be running a windage tray and if I see oil pressure problems I will upgrade to a Canton tray.

 

The stock windage tray was nowhere near fitting with my 383. I ended up going without, but using the stock pan.

I used ARP studs and the stock windage tray. I had some little extenders machined from hex material, 3/8 fine thread to fit over the stud threads and then cut 5/16" coarse threads on the top for a nut to fit on top. It made a perfect step on which to place the windage tray at the correct height. I made three of them and they hold the tray perfectly.

Oh yeah, I also have a HV pump. I see hot pressures of 40 PSI at idle and 65 PSI under load. No starvation problems here.

 

ARP main studs here and no tray. I installed the Milodon pan.
