Ok getting closer to finishing my 427 motor It will have TFS 245 heads and terra yella rockers with morrel lifters. What size push rods should i put in this motor. Will be seeing about 15 psi of boost at first then later 20ish

Not length cause i will be checking that, but the thickness and type?
How long does it take to get pushrods ? I might need them to be ordered to a custom length so i can set the preload of the lifters if its not a stock size.

3/8ths Smith Brothers is what I am using.

Smith Bros, Manton, or Trend. All are excellent pushrods and can do custom lengths in a short amount of time. 3/8" x .120 wall one piece with oil restrictors.

Why with oil restrictors?

i bought my 3/9" from old W2w

To keep unnecessary oil from pooling at the top of the head.

3/8th's from W2W was more then likely Smith Brothers.

Ok sound good i was worried about oil pooling in the head cause of my MEL10296 oil pump

So going to order Manton pushrods that are 3/8 but how do i order them with a oil restrictors? Are all oil restrictors in pushrods the same ?

It provides primary oiling to the bearings

.040" hole in one end is the oil resticter.

Pushrods with a .040 oil hole. Is there anyway this could cause any issues like lifters pumping up or not getting enough oil ?

Nope, oil is fed from the lifters up the pushrods and into the rocker arms/head area. When ordering, ask Manton what size restrictor they recommend for your application.
