I have a 385 lt4 with a solid roller setup that's gonna be a street car. I have good lifters and was wondering if you have too change out the rear oil restrictors in the block or if they are fine as is?

 

I have morel lifters with high psi oiling pin

 

What lifters?

 

morel 4843

 

Ok found out Morel does NOT recommend running any oil restrictors with there lifters. So guess ill be good, long as it doesnt suck the pan dry.

 

Are you running a high pressure pump?

 

Everyone has their on opinions. I've never liked the idea of restricting the oil to the topend. Yea the solid lifters may not need as much oil being they don't have a hyd mechanism to keep pumped up but with the increased spring pressures on solid valve trains I'd say you need that oil up top to keep the springs cooler along with the rockers trunion bearings. Just my thoughts though.

 

I have a melling select with 10% more volume and anti cavitation.
