yes, this tool can and will allow you to cut down the top of the valve stem guide enough for you to easily run a high lift cam. I've done this with a .550thou cam no worries.

@@reapermansoldholdensixmech8675 solid mate!!! Appreciate that info

@@davidhole8229 You're most welcome. No dramas.

It is a real beauty, and I am still using this as my daily. The cam is an unknown that I pulled out of a worked red motor sometime ago. I had done some measurements awhile ago with a set of vernier callipers, and worked out the lobes are giving around 420thou lift at their peaks. So, somewhat of a nice mild cam. I tried to find what cam manufacturer made this, and a lot of old hands said it was an old speco blueprint cam of some description. The long duration gives some lope. I had changed the weber 34adm over to a weber 38 dgms. Is a much better carburetor yet again.

@@reapermansoldholdensixmech8675 awesome thanks for the reply, this is a very similar set-up I'm wanting to build myself for my hr. I'll be chasing torque and throttle response. 😁👍🍻

@@jalopyjalopy9489 I've done quite a few over the years, a high torque cam is what you'll be wanting, high compression pistons and if you can get one, get a high compression/closed port head from a 2.8 blue vc/vh commodore motor. I, right now, am building another one just like this and will be experimenting with an EFI setup. I've got most of the bits now after scrounging around the last few weeks, and have a nice block and crank to work with. I've got a 3.3 vb commie red block at 20 thou, and using a vk commodore counterweighted crank. waiting on 20thou flat top pistons and molly rings. I'm looking forward to see what it does. Also, I had gone from a weber 34adm to a weber 38dgms. The engine runs better still.

@@ForIndigenousRightsTas yeah cheers mate, that's exactly what I'm chasing at the moment is a 12 port high comp head and yeah a torque cam with low duration and high lift. Thinking to go around 220 to 230 @50 with as much lift as I can get with that duration, 450 to 480 lift roughly.. Your motor sounds nice and tuff, are you building it yourself? You'll have to keep us posted with ya build when you take her out for a spin. Good luck with it mate 👍👌

You're welcome. I am glad it was of assistance to you

Ah yes, Perth. Perth is about 30mins north of where I am living now. And we don't have good access to engine machinists anymore here. Right now, if a motor needs a bore out, it's cheaper to get it done interstate and sent down, and prob be at a better quality finish also

that was my thoughts exactly! Was so tired of the factory rubber band seals not lasting.

Had a laugh at the carby description, it fits nicely in there length wise too.

@@wobblyplanks Haha. yeah, just a single barrel ford carbie I had. Looked at the listing number on the carbie body to figure what it was. was sitting with random junk in my shed, and thought damn, that'd be a good match. it was, and had served it quite well. Eventually swapped that system over to the proverbial 350 holley and it delievered a lot more grunt still. The engine was an incredibly good fit, and didn't take much to make this work. gearbox mounts were in the right place and all I had to do was raise the mount up a few inches with some box steel. motor mounts had to go back about an inch or so from memory. Heater hoses from firewall was on the right side too. Was quite easy overall to get this thing running in there, and the only single downfall was having the trimatic behind it which used to fair wind its guts out at 100kph. It'd do around 3600RPM or so. If I had the chance to do another auto one again, I'd move over to a t700 conversion, so it has overdrive. Amazing the pull this thing has though. Pulled a vx commodore wagon wreck out of the mud from my yard to the road at around 50 meters away with no tyres on the thing. It was quite a good conversion. I would certainly do it again

I'm fond of it that's for sure. I've since changed over to triple 2" su carbies, but I'm not 100% sold on the redline triple su manifold damn near touching the extractors. I'm actually going to go back to the weber 34, but will be running on an aussiespeed 12 port manifold which I've now got on the way. The weber 34 was running very well.

Thanks mate :)

First thing I investigated. Won't fit or hold in there without some work,.

Could be mate. I haven't looked into it though. The old girl used to sit at a fair warm idle travelling along the highway at 110kph. I've since swapped out the 14" mags for 15" vx ones and had also installed a factory 5 speed gearbox. I've got a spare just incase that one decides to die at any stage.

Thanks mate! :) Also found that you can get umbrella seals from f*rd 351 motors that'll fit these 11/32 valves and even those are still superior to the traditional black rubber band seals that tend to be rather sensitive.

Thanks mate! Man that engine pulled incredibly well for awhile. Silly me for not running it in carefully before giving it maybe a little too much hell. Needless to say, I'd busted a piston ring in the process and got quite some excessive blow by. I'd since switched motors to a 3.3 black and also installed a new yella terra alloy head along with a set of triple 2" SU carbies. It's running quite nicely and I'm now being a bit more reserved with the old girl. That weber carbie was running quite well and I've also since picked up a couple more to re-jet and play around with over the upcoming summer if I get the chance. Also have 3-4 more holden sixes I'm looking to slap together over that time.

Thanks kindly. it has done it's job well. I still use this old wagon on a regular basis.

Thanks mate! :) Comp cams make the arbor/guides and the cutter tool. Arbor size is 11/32, part number 4732. and the cutter is to cut seats to 0.530, and can be purchased from here: www.compcams.com/valve-guide-cutter-530-for-standard-ptfe-seals.html. Viton valve stem seals can be bought from many places, but I'd bought a set of v8 ones from ebay that did the job rather nicely. A lot cheaper than buying a set to suit the holden six, and have some spares to go with it.
