oil restrictors dart little m block
I am completeing a build on a dart little m setup. The cid is 436 strictly for drag racing. I had orderd a short block from a reputable builder. I am about to install it in the car and a friend remineded me to check for the oil restrictors in the block near the back of the engine, I opened them up and found no restrictors at all, just wondering if they have to be there and if so what size is recomended?
Thanks
Al
