414 Stroker Build part 3 Tubing the Block # Small Block Mopar

- Finishing the tubing process on the 340 Mopar block for solid roller cam. This blocks off oil to the lifters and increases oiling to the main bearings. Motor will be a 414" stroker. 1
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.
Nice work, thanks for sharing the process.
Take care, Ed.
Nice work !!! 👍👍 Many don't know, but..... this is the engine that was to be used to whoop up on our Drag Truck! LOL
Speaking of Drag Truck, it is one of my favorites on RUclips!
Great video. Probably a stupid question, but how are the lifter bores and lifter-cam lobe interface oiled now?
Splash oil from the rods .thanks for watching.
Yah, good point….I wouldn’t do that.
That’s some back yard BS….
A friend of mine did this with a circle track 360 and it survived three seasons easily I raced a big block Circle Track and never had any oiling issues at all
Thanks for sharing your knowledge. 👍🏼
Very good!
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.....
yes finally found someone building a 340 now i got to look through your videos.
Thanks for watching!
Wow! Thanks for sharing!
I hope some of this stuff is useful. I know I've learned a lot on youtube!
Thanks for this video. Been looking info about tubing Mopar smallblock but theres no info anywhere. Going to do this for stroker to eliminate too low oilpressure coused by rollerlifters .
Glad it helped!
O my.
I don’t understand the point of tubing?? Is there a pressure loss if running rollers??
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.
This seems like a carry-over process from early hemi's , the oiling and block layout is very similar .
I did not know that. Thanks! I'd love to build an early Hemi someday.
That's a great video! Thanks for sharing!
Thanks Cley.
I'm faced with possibly having to do this? How do the lifters get lube? Is this Necessary if you run a hydraulic roller? Thanks for your help!
If you run any type of hyd lifters, you would have to drill holes in the tubes.
Solid lifters get plenty of splash oil.
Didn't realize anyone still did this.
A few of us old guys still do. Thanks for watching.
I don't know much about Mopars what is the purpose of this?
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.
I sleeve my lifter bores for 1.5 thou clearance. If you can fit 0.906 broach through there they are too big.
The broach is 0.906, but does NOT make the bore 0.906. Cast iron is pretty elastic.
You could hammer the broach through a hundred times, and 101st you would still have to hammer it.
Bushing the bores is the best option, for a lot of reasons, but this method works for us low buck guys.

Good stuff man! Thanks for sharing!
Thanks!
Well done. Thank you.
Thanks!
Now, when you are all done doing ALL the WORK to make it "better" - you still have a Mopar product.
You "better" believe it!! Mopar or nocar for me and mine!
@@CCR414 As long as you enjoy what you are doing and what you get out of it. I hope it runs well for you.
@@burtlandcastor8359 Thanks. I don't know what brand you like, but if you enjoy it that is what matters. To me the work is fun, and I tend to do more than I really need to do.
