Quick update. I spoke to the fellow who's doing my 302C heads, they came up well with no cracks and already have brass valve guides in them. Beauty. The downside is that the valves are shot, they've been previously machined and then used on LPG so are not good to reuse.

I sent him a set of valves from another set of open-chamber 351C heads I have so they should work fine. The new springs and seals are also there, and I've opted to get hardened exhaust seats installed so I won't have to worry about them in the future. He said it'd be for the best as the seats show some signs of wear and after a valve job may end up further recessed.

All in all its going along swimmingly.

Indeed they can. So can 351C's... and I just happen to have a few. Mind you the LS's would be much easier to work with.
 
 
I saw that! I won't spoil it for anyone who hasn't watched, but the output with a standard cam is fairly decent. Aussiespeed do a manifold for them and that'd be the way I would go if I were to do it. The stock head can be worked a bit, plenty of info stateside on it. It's no Barra, but it'd be interesting purely from a 'what can I do with it' point of view.

Nah they're a big bore 6, 4" by 4" stroke. They're about 2" longer in the block than a crossy. They will take a 390 FE piston with a rebore apparently. Bore spacing is similar to a small block V8. Cut up LS heads can fit with a bit of work. So sort of like a big block 6

Exactly. I know the benefits from the job would be worth it but I'm stretching expenses at this point. I'll see what its worth but honestly it'll probably just get a standard lapping job and be done with it.
 
One thing I will take my time with is the porting. I have my carbide bit, I have my preferred cordless, I have plenty of cutting fluid (ie degreaser) and I have an esky, a comfy chair, a milk crate and a good speaker system with some tunes. 
 
 
My last combo of this exact comp & cam spec was an absolute hoot so with some porting and springs it'll be even better. I also have a proper carburettor this time - the Brawler 650 - so again it should work a bit better than the old 600 Vac I had on the last one. 
 
The only other thing I'd be looking at is using this combo in something else down the line and going to a 300ci 6cyl setup for the 4WD. They're an engine with an amazing history and I'd love to put some effort into one and see what it can do. We'll see how we go on that front, it'll be a long-term project per the aforementioned espenses limitation.

Go the seats at that price it's good.
3 angle cut on the valve seats is worth the money, makes for a much better flow in and out of the chamber.

Great minds think alike my good man. Great minds think alike.

Just rang him. He said it was 30 bucks a seat, so 8x seats is $240. Geez. Maybe I should just do it and then not have to worry about if I decide to blow it or something later on down the line.

I've got a few 351C 2V heads lying around now so will probably use those valves if they measure up properly. I've used stock valves before with this camshaft and drove it around just fine for ages. Its a gentle profile camshaft, I think its quoted as 292 degrees duration with 219@50 and 262@006 for a max lift of 505.
 
I didn't ask the machinist about the seats, but if they aren't done I don't think I'll bother. I've worked out before that Flashlube only adds about 2c to the cost of fuel per litre, so if I'm using 15L/100km then thats 0.3c per kilometer in Flashlube. To  even at a cheap cost of $250 for the seats I'd need to do over 83 thousand kilometers.

I would, but, it's your money.  3 angle valve job, while your at it ??😉

Has the machinist looked at the seats? I was expecting mine to need hardened seats only to find that they were done already when I was having them tanked and reco'd. That was a big cost that I was happy to not have to cover.

If they're not hardened, no big deal. I reckon if you're not going to flog the arse out of this truck, just stick with the valve saver on the stock iron heads. Hardened seats take a long time to pay themselves off if you're not doing the km.

That's a shame about the valves. See if you can score some one-piece valves vs the 2-piece stock ones. Those are notorious for ripping valve heads off with anything more than stock spring pressure and rpm.

2 head gaskets will fix that..!  😂
 
Check your compression ratio with zero deck, as you may have to run her on Premium, not cheap these days.

Yeah I'm always happy to have a go at porting. I've got the carbide bit there so may as well. I will probably do some research of the "do's and don'ts" and then go through the lot but if its anything like the GT40P's I did for the Windsor it'll be fairly straighforward - clean up the flash, smooth out where the casting meets the machining and go from there. I won't be expecting miracles but even a small gain over stock would be nice.
 
More good news by the way. Looks like this thing is a stock bore 351. Heads seem fresh, too.
 

 

 

 
We're on a winner so far!
 

Parts are turning up so time to have the engine apart. Its sludge city in there.
 
On the upside I got the carby off and its in good condition. Not much play in anything and certainly ran quite well. I will likely refurbish it and sell it on, if anyone is keen let me know.
 
The Holley I was going to use to start with I fitted to the 250 crossflow I sold as part of the deal... so I'm rebuilding another. All good so far, fingers crossed.
 
Heads off in the morning, I'll see whether she is a 302 or a 351.
 

 

 

 

Cheers mate! Yeah I was reading up that 37's rub at full lock on an unmodified truck, so 35's it is. It's running 8.25-16's up front at the moment which works out about 33, and I definitely wouldn't want to go smaller.
 
I'll go aftermarket steel wheels. I'm talking to the local place about it, he's getting into his catalouge so should come back with something for me next week.
 
The clutch master and slave I can't remember honestly. I'll look up my ebay purchase from a few years ago and see what I got. From memory it was fairly generic Protex stuff. I made it work with trailer hydraulic line to join them, and used a drilled fishing sinker to make up the hydraulic olive needed for the master connection.
 
Meantime here's my dodgy floor replacement. I'm not a good welder, but managed to make this thing solid. Not pretty, but solid.
