Im trying to put back together a Force Fed shortblock and the windage tray wont fit on the main studs, not to mention I dont have any nuts for the ARP studs either. Do I have to drill the tray bigger, or can I do away with it? Anyone know what size threads the ARP studs have?

 

yes you can drill or just file them out. it takes about 10min to do.

 

LME sent me new nuts & spacers so it would fit. But of coarse i do not remember the size Call your builder they should know right away

 

same thing happened with me.. just call your engine builder they'll give you the size our they'll send you the nuts... i used a drill with I think a 1/2 drill bit, i think you only need to open three of the holes bigger..
