Holden 6 cylinder 202 (3.3litre)

Hi and thanks for watching.
My Holden 6 cylinder rebuild.

One of the great things about the Holden six's is how well they lent themselves to modification. Didn't take much to get more go from them.

Nice job mate. To accurately date the block next to the time clock on the rear right side there will be a cast in code like 6h1. 6 day of august 1971. The best external oil pump feed is to place a 3/4' thick plate over the original oil pump mounting face. Tapped for a 12 an fitting. And relieve the internal radius . Like you have done. Tap the front oil gallery with a 1/4" plug. Prevents the press im plug poping out. Next tip is to cresent the upper bearing register in the block and to drill an extra feed hole in the upper bearing. Creates extra flow to the rod bearings. Does not matter what happens with the external pressure or flow. Ive had great sucess with just a wet sump. Big internal pickup. Baffled trap door sump.

the 202 won 1st 2nd and 3rd in the Repco reliability trial was XU1 tuned

[markfiddyment]

At the back where Holden is cast just below it is 8H3 so is 8th August 1973

The red engine was one of the best motors holden ever made. I'm sure this will be a tough engine when built.

G'day from West Australia😊

Ask your engine guy has he ever used a slot in the lifter tunnels to drop oil onto cam lobes!

Just something from yesteryear.
3rd generation engineer in the family saying, I have had 6cyl motors rev far beyond 9k with that little modification.

And if any interest I still have 2 triple manifolds. One Webber's/ Delores.
And one for hmm square 4 bolt carbs. LMAO can't remember what carbs they are. Must be age catching up with me 60 in November, 43yrs trade life.

Come to think of it still have flywheels and flex plates, and alsorts of goodies. 😊

Feel free to reach out, cheers Steve.👍

hi came across your build good work will done i love the old red six is there a update you can post ?

[thatoldchevy]

People forget that oil balance in L6s is an issue.

We drill a hole in the side of the block to access each gallery, then tap it and provide brake fittings / bundy to join all the oil galleries together = consistent oil pressure front to back.

8 of 1973 xu1s ran fully grooved main bearings and dowel pinned crank to flywheel

[rodfonda]

One good tip I've read about, is to use a hydraulic roller cam, but with solid lifters set at .005" lash, less lifter weight, more roller life, better harmonics, better valve control/less aggressive ramps, and without having to use monster valve springs

13:19 how much did it cost to sleeve the bores ?

[ldnwholesale]

Plenty of Holden race engines with roller cams with std size cams. Big cast iron cams will break behind the 8th lobe. Lifter bushings resolves that issue.
Sleeving will cause the engine to twist and flex. Not near as strong as OEM, A sleeve to save a block does not hurt much but all 6 [or 8] makes it a mattress. I have seen it tried several times and it never works. This in race engines and since you are playing solid roller it is a race engine. It will hammer main bearings and will not hold a headgasket. One of the problems with factory LS blocks.
Grouting blocks is really racecar only. It does stiffen up the main tunnell but at street rpm and speeds will cause cooling issues.
And I have seen lots of these engines from HQ racing to Sports Sedans with Irving heads.

Whats the plans for the motor as in whats it going in & what trans & diff & car

[warlordofblood]

never seen the grout/cement in the water jackets method, why and what are the benefits, thank you and good work:)

[thewholls]

Good job - did you use actual concrete for grout or the commercial epoxy stuff….?

[johnzapper]

I noticed you have a blow out through the bore on number 1 cylinder. this was a very common problem with high HP, and boring them to .0060 th or more. We used to throw these blocks out at that stage.

[AndyPat]

hi thanks for the vid. where abouts are you? Interested in this build cheers Andy from Riverina NSW

[leebarber]

What are you trying to make
A stock engine or is is going to be a hard revering engine 🧨🧨🧨

[GG-rjoj]

Would you like to share what conrod you intend to use. I realise you said its .400" longer. Will you need to grind the crankshaft big end down to suit the conrod.

[theworkshopmechanicchannel]

I spoke to my engine guy the other day,
He said he will start on mine once again in the coming weeks
