4 Bolt 4V 4MA 351 Cleveland with "Hank the Crank Oil Manifold System"

[@kaivette642]

This is amazing to see! I’m Hank’s grandson, and since he passed away, I’ve been doing so much research on all of the projects he was involved with. He was part of a rare generation of innovators. He was in business only a couple years after he left CSC so that’s cool that you have this from the early years of his business. I’ve only read a little about this system so it’s crazy for me to see this in real life! Thanks for preserving this piece of racing history!!

[@seanmadill283]

That is definitely the rarest 351 Cleveland I've ever seen. What an incredible motor and oiling setup that is . It looks like the holy grail of Cleveland's. Thanks bro

[@ronnieboucherthecrystalcraftsm]

the intake manifold is always machined to match heads - ALWAYS ! - 4v clevland saw moffat racing oil in the sump Boiling = oil cooler - just to get the oil out of that hot engine = hot heads cooking oil = 500 hp easy mod for the legend 351 4v cleveland

[@maddansant3064]

Cool find and thanks for the share. Certainly a great system that was designed to direct feed the crank mains and big ends as priority straight from the oil pump instead of the crank being last in the factory design oiling system. At (4:20) you mention the oil manifold is tapped into the R/H oil gallery and at the rear is a feedback loop return line. Those 3 lines in the valley are actually each angle drilled up through the block from the bottom at mains #2, 3 & 4 bearing oil passages, and larger at the upper end of the new holes where the fittings are with tubes inserted. Those 3 are the direct pressure feed supply to those mains/big ends. The external pipe added at the rear, where the oil pressure sender unit is usually fitted, is just fitted with a BSPT fitting to direct more oil to the rear main, and a restrictor plug was added in his design to the front of the R/H lifter gallery to direct more oil to the front main. What would be a great addition on this vid would be to see what Main Bearings this engines builder chose. Half groove? or Full Groove? The factory crankshaft oil drilling ports on journal mains 2 & 4 caused a problem on big end bearings 2 & 7 when kept in the high revs because of oil "clock on..clock off" timing. Bearing choice helped this. Aftermarket cranks design fixed this prob. Cheers bro. Very Nice.

great info

[@lukealsmith]

More of this tech talk man. I really think its important we retain this information since it varies on different forums

[@Brodes1983]

Great explanations on these details you never normally hear about.

[@nbenn8216]

Can't believe I only just found ur channel... Ive been binge watching. U and ur bro make an amazing production team! Keep the cool content coming.

[@thclevoking]

Thanks for the support mate, if you want some free stickers shoot me a message on insta or FB

[@kevinblevins2612]

One of the best Cleveland videos out there

[@cammontreuil7509]

A yellow paint shows up oil leaks. That's why it's painted that color.

[@darrencameron6639]

You certainly find some unique engines. Very informative with your details about engines plus great parts for sale. Wishing you both a great month & of course 2022. Catch up with you both 2022 with my 351 2v Cleveland. Let's make a lot of lumpy noise in 2022. All the very best to you both & your families. Dags🙂.

[@cavscout62]

Absolutely Golden! I hope you post video of this thing from 1st start to full redline runs in the car !🤘🏼

[@TheRCMaster]

What a cool nostalgic motor definitely an interesting watch, nice one bro 👌

[@johnkraft7461]

Excellant video as usual guys. What about the use of full groove main bearings with a standard volume pump ? Paul Dilley and his kiwi mate Chris did a fascinating video on this topic - i think they said mains #1 and #5 were the critical ones. Cheers 🙏🙌

[@gmans7859]

Thanks Guys. I always learn something from you! That's a special piece.

[@BlakeHoughton-c4x]

Great video 👍, it would be great if you can still get this setup

[@aaronhogan2371]

Thanks for the show and tell on this one. Its pretty special and hope its going into a special car.

[@pauldilley453]

nice old piece of history! should have had a xxxx beer as well

[@thclevoking]

Thanks mate I do enjoy your videos, nothing beats a cold XXXX on a hot day!

[@MrFathead]

That is a cool engine. Make a video of it when you get it fired up.

[@ronniebraine9692]

Great video guys. what a cool bit of kit. That is an awesome and rare Clevo from the 70's. Brilliant. Thanks!!

[@RobLock-i2c]

Early blocks have the cut at top of bore

[@michaeln9905]

That's the same thing I got same block same heads but no machine work has been done on mine that oiling system is awesome a lot of work has been on this very cool are we going to hear this one run

[@ralphthomas7868]

Excellent. You're sitting on Gold.

[@svenomick5857]

Lot off great ideas there Clevo King another good video You two cheers Mick.

[@user-du8cs8sn2v]

Very cool. Would love to know it's full history. Sounds like you've been watching the Powerfish too :)

[@swanie1971]

great video thanks for sharing your knowledge and holy grail clevo with us

[@KINGSFORDLIFE]

I had a 351 with a 4mab crank 4mab was on the crank. I also had a factory 302 cleveland with a quadrajet 4 barrel and it had 4. on the heads

[@landau393]

Woe that's a awesome Cleveland .. thanks heaps for sharing it. i love it 😍

[@davidgray3176]

Look at video for turning 7k rpm on cleveland cranks oil clocking on 2 and 7 rod bearings..makes for interesting vivie

[@stinkfinger1942]

Can not wait to hear this beast!

[@pnr9730]

Wow good find

[@user-ld3tf3mi8w]

Great find Amazing piece of history, you must have mates in southern US to find this beauty Question mate , can you open up the valley in a regular block like this one ? Cheers

[@tallstrom]

Thanks, always interesting!

[@hoedemakerbart]

Interesting. I want to modify the oil flow on my 4v in the near future. Still looking for the best way for high rpm sustainability oiling. Cause i live near Germany and i need to be able to turn 7k continous if i want to

[@zeuseli3010]

great information guys thanks

[@michaelgiglio1571]

Nice to see. Go the fords

[@vicsspeedperformance950]

Hey Mate, beautiful piece would like to have one of my own 🤙🏿💯

[@yella953]

the block setup like that with the slits down the middle do they crack often

[@Little1cookie701]

Great piece of history. Good find. Do you think it was used in drag racing or Bathurst touring car maybe? Thanks

[@thclevoking]

It came out of an AC Cobra that was done up for drag racing

[@Tom-th1oy]

Great channel…. What are the standard 2 bolt 70-71 4V Crankshaft marks?

[@thclevoking]

4MA usually mate for that era

[@ablejohnson]

Bad ass!

[@ksacky]

Why is it supplying more oil to right side when right side already gets oil from 9/16 galley first, it's the left side that is oil starved.

[@tonymontana897]

So the elongations of the oil return holes in the valley section, do you recommend this for ALL Clevelands or was it only for the Hank the Crank engine ??

[@thclevoking]

It doesn’t hurt to do in any clevo, opening them up too big can weaken the block a bit so it’s easiest just to nicely remove the shape edges

[@tonymontana897]

@@thclevoking Awesome. Thanks for the info mate.

[@paulkeogh1191]

I agree just chamfering the holes and smoothing the valley is all you want.

[@jamesburke7905]

1972 351 cobra jet base engine

[@guyharrison909]

How much power would this engine make?

[@thclevoking]

It was only estimated at 460hp mate it was more designed to rev high. A modern camshaft would see it make around 550hp pretty easy with all the work in the heads.

[@PCMenten]

302 heads? It has a fifth bolt hole for accessories.

[@thclevoking]

4v closed chamber heads

[@drcolster]

Everything has changed these days...Bronze Lifter Bore Bushes, a few other small mods....Done...for 8000 plus rpm..

[@brimech73]

Where did you find that engine?

[@thclevoking]

Word of mouth I’ve had it for a long long time.

[@jamesmclennan3618]

That would of been a hand full

[@EllyVint]

Real life Forza Horizon!

[@thclevoking]

Just the guy that builds them these days lol

[@BlueOvalEdge]

Yeah, a junkyard 5.3L Chevy LS is 10x times better than this engine (bullshit alert). Cool video, keep up the good work.
