Actually it was the balancer that stripped it now I recall, but with a decent puller the rattle gun should get it off. Don’t forget to put sealant in the balancer key way when you re-instal it, which is why I had to pull mine.

Don't know why Crow couldn't get .600", Camtech got it with mine without using Chrysler lifters.

Cheers
The eBay one is same as mine, stripped long ago
Welded a decent nut on it for a decent bolt.
The weak part is the bolts that are bending sideways when
I give it some welly, plus there is only 2 of the skinny buggers
Might try finding some tube to slip over the outside to reinforce them.
Rattle gun should keep it straighter than this ssgorilla with a breaker bar
and lump of pipe
Thanks for the tips

I’m not sure what to make of that either

Here’s a few more pics I should have put up earlier

Looks a good buy
Nice set of genie 88e pipes too, those are what I am using.
Very very similar to the 1.5” version of the hm9’s everyone went nuts over
Not quite as straight off the head face as the hm’s , though.
Still wonder why there’s no love for them here

[claysummers]

They are cheaper and more complete than the set I bought although wrong manifold for my application and only 1.5”. Got half a mind to buy them to take the linkages and choke mechs.

4 bolt flanges? More like 1 3/4" ?

[Bruiser]

I reckon they are the same as what you’ve just bought
1 3/4 hs6
The straight lynx manifold is no good for your eek, right?
Could probably flip it on easy enough
Or just give your firewall the demon tweak
Have you checked out those needles yet?

Oh yeah, finally got that prick of a gear off
3 days of pissing about
One less thing

[claysummers]

I’ve sent a message as there is no phone number. No I haven’t pulled the needles yet Bruce. I had a play with one of the covers when I got them and it didn’t want to come off easily. I’m trying to focus on rust repair. Those are the VK injected style pipes 6 into 3 in to one aren’t they?

Yer, 6 - 3 - 1
I can measure them up while they’re off the car if it’s any help

[claysummers]

That’s ok thanks. I will on sell them probably unless they actually fit in the fb, which I doubt. They’ve taken my money. I will be there in June. Wonder if there is anyone on here can go pick them up and hang on to them for me until then……

Been on the road for a week now, and thing are looking good
After 3 weeks of sweating over every move to get it all ship shape, all is well
mostly
Did the whole thing with motor in car, kneeling down working through hole
where grille and radiator live
Had a win getting the timing cover back on, which I was most worried about.
Didn’t loosen the sump even so it can be done. No leaks. Yet.

Got myself a graphite gasket, on Adam the redmotorfiend’s advice
Weeping coolant all along the dizzy side. Re- torqued a little bit tighter, still weeping.
Checked torque wrench, to get 75 ft/lb I needed to set it to 90!
75 would have given me around 60 only
Found a method to re-calibrate the thing, it’s only a cheap one. It pays to check.
Re-did it today, no leaks so far

Rather than put my su’s back together and tune them during run in, I
decided to go back to the trusty old 4 barrel to make firing it up for run in easier
and the bastard shot fuel out of the rear vent like a fountain.

Number 6 vac sec secondary plates have a main jet equivalent to a 72 jet, so I tapped for primary
jets on the back to go smaller- which held the floats down. Had the timing right though, it fired
instantly before the flood started
Was going to prove a point to myself and get this Holley running minty on this motor before
getting the su’s together, but the thing didn’t want to idle well at all
Thought I knew a thing or two about Holley as well
Strange, it always ran sweet on the motor as it was
Had bits of wire in all idle air bleeds, even in the transition slot restrictions, the whole bit
which helped, but the idling was only just iffy at best.
It used to use a ton of fuel previously, I’ve since learned smaller jet and bigger pv restrictions are the way to get
Leaner cruise and richer w.o.t. Gave up on it before getting that far.
Ran ok with 59 jets, but for giggles I put 62s in and found plenty more power.
Would have taken a year to get it sorted, waste of time.
Banged the sus back on. Instantly better
Can’t give it the oats yet, inner valve springs still need to go in so I am rev limited to about 4000
So have been tuning to make it drivable down low

I am amazed to say for such a big cam it is behaving itself very well after a bunch of hours of tuning fun
I can drive the back streets at a non-child endangering speed and get around corners in 3rd gear
It will now roll along slow without surging or bucking or having to wake up the neighbours
I’ll wait till the inner springs are in and then I can start faffing around with needles seriously
to suit the whole rev range
and see what she’ll do

[claysummers]

Great news Bruce. Sounds like you’ve been busy.

Good stuff Bruce.

I think that those who say 'big cams are a pig on the street' haven't actually driven a proper 'big' cam on the street.

[LJ RB30]

When are we gunna get a vid with some sound of this?

That head is just some red motor porn so im keen to see/hear the outcome    

[claysummers]

Nice back road drive to Willunga from your place Bruce. I’m home all Easter.

Thanks,Clay
Will get down there for a visit one of these days
Would be great to check out what’s going on in the shed there

Haha I will cop that one on the moosh
I see the irony of me being Mr cautious about biggies and ending up with
what I’ve got now

[yel327]

On mainstream engines hydraulic rollers give you the best of both worlds. Anyone tried one on a red 6?

[claysummers]

A mate has them in a 300hp 202.

Sorry for the late reply, Trevor
I only have a boring video of running in the cam at the moment
If you can imagine a running engine with a quick moment of my hand
giving the carb a tiny slow blip, that’s about it
I will take other ones eventually
Then I have to figure out how to put them up on here..
If I can find an 8 year old to show me how to drive this computer
Not really rushing things along here, still haven’t done the springs yet
and having fun with the su needle tuning.
Doing it kind of by halves at the moment, waste of time if the upper revs
can’t be tuned at the same time.
I think I need to make sure the damper springs are going to have the piston
opening point correct at the top end before seriously sorting the needles anyway.
I have a set of RHs, TWs and the BBFs they came with.
The new Aem o2 meter is keeping me occupied and shows me
that none of these come close to being right
Spent a day trimming down the super lean BBF ones
to be close to KU/OA7 size to start with just to get things close for starters.
Plenty better, but still a bit lean on cruise, so idle needs to be set a bit too rich for now
Just want it useable until springs are done, (so I can afford the fuel bill or not melt it by being too lean)
then sneak up on it and get it sorted properly
Spent years getting to know the engine with old spec, and learning to tune it,
had it going good, too
But now it’s a whole new game, more finicky than before.
Have to take a different approach and learn some new tricks

[Bruiser]

Been flat out on this thing since April with carbs and needles and dizzy curves
making plenty of headway
Top end power is nowhere near what I was expecting, next thing is to get a bigger exhaust on to let it breathe out a bit.
The engine builder told me there was the potential for very high 200 horsepowers and that a 3” exhaust would be a good thing(?)I have a feeling he is looking towards maximum numbers but that’s not what I’m really after
unless the car can behave itself within reason when not going flatstick as well
My first one eyebrow up question was “ won’t that kill my bottom end.?” Was assured it wouldn’t
Been thinking long and hard to design an exhaust system, and have seen all sorts of points of view what will work
Have seen this table a million times in my travels

They all state 2.5” pipe is only good for 232hp and I believe it means at flywheel
Then a local exhaust guy tells me it’s good for 400hp???

After all that backstory, has anyone ever had the need to go bigger than 2.5 pipe for a 202 similar to mine?

[warrenm]

I run twin 2 3/4" off the extractors, which has 275 at the tyres, 3" wont kill the bottom end but could drone unless you have some type of resonator before the diff.
