Timing cover looks good, who made that thing.??? 400 same as 302/351..?

Did you replace the oil pump during the rebuild.??

Just a word of caution, XR-XE clevo extractors is a bit sketchy.....

XY slightly different to XD.

Manual steering.

FMX trans, etc, etc. 

You may have to 'modify' the extractor tubes. Pacemakers are notorious for not quite right fitment. Good pipes, Aussie made, but not direct fit. 

Yeah, fair enough. Not knocking the guy's intelligence or knowledge, he is a Guru.....  I just have a short attention sp..  Look, a squirrel.

Vizard is good but I feel that his tech videos are an annoyingly slow drip feed of info.

Yep, he's the worst...... So knowledgeable , but so hard to listen to.

There must be some Hydras lying around in wrecking yards or on shelves somewhere.

I'LL TAKE IT...!!

Yeah, I've learnt heaps from the Interknob.  Uncle Tonys, Luke (Thunderhead289), Muscle car solutions, all have interesting videos, once you trawl through the garbage while they try to entertain you. Good vids on the Rockys Roadshow channel, full rebuild of TQ and Rochester carbs, but MAN.!  he drags it out..

Good stuff, mate.   Carbies are a dying art.

Agree with all thats been said.  A good paint supplier can put GOOD quality paint, any colour/brand into an aerosol can.

This weirdo thing is a dual stage power valve.


 

Hmmm........ cool idea. If it actually does what its designed to do, why didn't we see more of these little fookers.??

Yeah, did the same with my Fairmont. Kept every part in the shed, in case I wanted to put it back to stock

Bah ha ha..........that's never happened to me. Not even once....

Small drill press mill with a fly cutter, and cross drive table would be nice.

Wow..!    This is going to be spectacular.  Well done mate, all the good gear, in a sweet little Esky. Will go like stink, and stop on a dime!

Yup, reckon you're right.  I have watched a guy on Utoob who actually mills the faces to get them flat again, Serious carby guy.!

They usually only have 6 base plate screws , 2 spare holes . 

Thanks mate.!  That solves that issue. 

Master at work. They are shockingly warped, all the ones I've pulled apart.  Maybe that's why the gaskets are so thick.?  

Cheers, mate.  I got a new power valve in the Holley kit, but, was interested in the numbers.  

I tried my local Adelaide Speed shop (Outlaw), and VPW, nil stock....

Weird number on the power valve 2.75 ?? Only thing on it...

Don't suppose anyone has any base plate screws.??   Only found 6 !

LOL. Just doing the same thing here.........

You'll be happy with a warmed over Clevo. Don't overthink it, just carb, cam, inlet manifold, ignition and extractors.

Don't rev her over 5 grand, last for years and enough torque to pull a house. If you want to go racing.......well, that's a WHOLE different Cleveland.

True. I've watched a few of his vids. I'm guessing that Mitch is a new builder, and not keen to start drilling out a head.

is that the go on a clevo? i have been reading not to do it on many other engines.
 

The castings from 1970 were average at best, if you stick a standard inlet gasket onto a small port Clevo head you'll see what I mean. I'm not talking full port and polish, just match the inlet port, to the manifold, exhaust port to the extractors, using a store bought gasket. It's not hard work, just a lick with a die grinder, its free HP...

Unshrouding the valves is great if you know how, but, not for the beginner. The hours involved in getting all 8 ports to flow similar, and the added weight of cast iron, just cheaper to buy an aftermarket head. They weren't around 25 years ago, so keen builders did what they could. Nowadays you can grab some AFD, CHI, or SCM heads.

Hi Bear,

 

Thanks for your input as well,

 

 

 

Very nice......  

Ahhh, ok. Should have read this first. LOL.  What he said....^ ^ ^  Yes, 4v size valves are worth it. and at very least, grind the manifold/head/exhaust to the same size as the gasket. Basically "port matching".

Yeah, I use NGK BP5FS, just change them every 10,000.
