Having fun reviving and driving old Mopars. Follow along as we work on our projects. 1967 Dodge D100 that will be powered by 414 small block Mopar stroker with ported speedmaster heads. 1970 Plymouth Satellite 4 door with 3g Hemi stroker power. 1971 Plymouth Valiant 4 door with 360. 1985 Dodge D100 with 360 Magnum and R/T heads. 1988 Dodge D100 with stock 318, that we will be doing a 360 build up for. We do our own machine work here in our home shop, and will show bits of that too, along with tips we have learned along the way. And, mostly having a good time!!!!
This is only needed when the oil bypass groove is exposed on either or both sides of the oil channel from unusually high lift or improper bypass groove width or placement.....
Some roller lifters have an oil band that is uncovered causing an oil pressure loss. I did this block to increase oil supply to the rods and mains. 16 leaks that are now gone. Thanks for watching.
@@CCR414 ok. Thanks. I was aware of the tubes but no one ever explained exactly why. We run a B with a roller but have no pressure issues. We oil the shaft rockers and run through the pushrods too.
@@CCR414 got it. I remember in the OLD dc manuals they put small holes in the tubes depending on lifters but never explained why other than roller lifters. We just did a B with a roller and are oiling the shafts normally and the rockers throw the pushrods with no issues on the dyno but it was hydraulic.
I have never seen “tubing” done before. Still not quite sure of the whole purpose of it. I normally would see folks use plugs with small holes drilled in them to restrict oil flow.
I saw an engine masters episdoe where steve dulcich did this mod on a set of heads. Fryburger and the other dude were doubting how much gain this would give him but the results on the dyno didnt lie! This really added some power !
The W2 rocker shaft hold downs are made for long valves and valve springs. I wanted to use standard length valves in the W2 heads, so I rotated the W2 rocker hold downs 90 degrees and machined them for the hold down bolts. I kept the 45 degree angled corners of the rocker pedestals in the original position, which required turning them around after rotating them.
It's main purpose is to prevent a massive oil pressure loss if a solid or solid roller lifter came out of a lifter bore. You cannot run a hyd cam with the mod.
