I would like to find an oil filler cap that fits directly into the valve cover. I would like to make my own engine covers and dont want to have a hole for it to come through like the stock ones do.

 

im not 100% sure, but that sounds like you might need to get with a manufacturer of frc's and tell them what you want, never seen an frc without a hole for a filler neck and cap.

 

what about a GTO? ive seen only a few pics, but it looks like either the neck is shorter, or the frc stands taller.

 

Theres a member over at pro-touring.com that was building custom LSX valve covers that were a flush mount threaded cap. Looked very slick. But it was just around 500 bucks for 2 fabbed covers.

ill be making my own frcs out of aluminum

 

Just remove the neck from the v cover and the cap will screw on.

 

you have done this?? Your saying the cap screws directly into the valve cover?

 

yes.
ive seen some cars/trucks that didnt have a stack.
valve cover, with the oil cap screwed right in.
it has the same channel, the stack just has a tab to lock it in place so you dont bust it loose while removing the oil cap.
good luck.
