Hey guys, I just came across this thread and joined up.    I have just built a supercharged crossflow for my vauxhall Gasser Drag car.    I’ve got a YouTube channel TasTuned which has a few details and also a Facebook page.    A few weeks ago I actually had a drag race with Rob Thorpe in SLY250 at Wilby.   He won!!    But the boost has now been upped and i plan to get it on the dyno soon to get her running perfect. 

230/236 cam won the day.
Was 2 degrees off being dot to dot. Sorted now though this time next week i should be able to give a review (yeah right plans never work out haha).

I used 4mm twin core wire,

most likely its the standard XE head, XD/XE heads don't have any ID between port 1&2, like the later heads, So open chamber 57ish CC
this is what the C2 mark is like

I run a dynotec(from precision) stage 2 214/214 @0.050" .495/.495" 111LSA in my daily XF ute, new cam ,lifters & timing chain, ported weber, pacemakers 2.5" exhaust. still has stock valve train, does really want performance valve springs but has done 40,000km as is & towed about 30 cars, regularly gets 11.06-11.2lt/100km highway (col auto 2.92 diff). valve float is 3800ish

Yep. That's it. Fuel pullover through the squirters. It does chronic things to mixtures and afr as outlined in old mates you tube video. 
It turns the accelerator pump squirters into a fuel injector. They just go open circuit. It's one of the most bizarre things I've seen on the dyno. Had a 2 barrel and 4 barrel crossy both do it.  Last time I was at Boetchhers on their hub dyno, Brenton their main brain and engine dude couldn't believe it.  He actually made me run the car up a couple of times so he could video it.  It's not something that occurs on their big dollar, US sourced v8's.  It actually does occur on very high revving v8 engines. 
 

My dragway indys on my black ute are 4.25" backspace & where to close to outer rear gaurd before i fitted the XY width BW diff with a 275, My 14x8's where 4.5" backspace and fitted a 295 under my ute. (If pics don't work look in photobucket bug thread for a fix for your browser)
Dragway's 4.25"

14x8 4.5"

Solid result there mate. Thanks for sharing. 

Here's the flow figures from my CNC ported C2 head with 1.84" intake valve,

i wanna race ya's as well in my crossy ,friendly heads up,to see how much more i need to do to it lol.

By no means am I having a go at anyone, or against others work, & happy for you to keep any detailed pictures to your self if wanted.
I made sure when posting pictures of my CNC ported xflow head to not give away any detailed pics of the ports, just a pic of chamber (which I did myself) showing CNC grooved bowls. as specially since they have there own R&D in that port design & its not my own work to show. & wouldn't even have a clue at its CSA...
I don't see posting numerical figures of a port as anything major, as specailly when you freely post flow numbers. but there's no worries here.. I like reading & compering on engines to others, against the build figures & to what they end up producing at the end of the day, to further my knowledge. I'm even very interested to see what power my xflow makes in its current form giving the my cylinder head flows up to 250.8cfm @ .650" & flows 236cfm at peak cam lift as where normally a head flow for a similar engine Ive seen to be around 200-215cfm.  Have a good week, catch ya's another day.

Yeah Ben Gatt was at the opening race at Swan Hill Dragway last November with The Wild Bunch.
Heads looking nice, might have a go at one of my sets. also reminds me I need to finish off porting the xflow head I started,

Engine uses oil and smokes too much, especially for 70,00 km.
 
So... heads are off, have been stripped and inspected.
 
1) Engine is pretty clean inside, probably because it's always getting fresh oil from needing to top it up
 
2) Oil deposits in exhaust port
 
3) Chambers were all like this. Plugs fouled but somehow ran fine (the MSD probably helped)
 
4) Weird scoring on one seat, either from new or from the valve face
 
5) Seriously crap daggy bits inside the ports
 
6) Anyone who likes umbrella seals, take a geez at this. Every one was at least split in 3 places, some smashed or missing the tops. I reckon they'd be softer if made from bakelite. At 70,000 km, that is rubbish
 
7) My head jig, for both disassembly and porting. The idea is that I can have both heads and all the ports lined up so I can be consistent with each shaping operation.

So its been a while but still going slowly. 
At this stage i'm going to order the kellford 230/236 cam next month. Meant to be getting some toy money soon, which will pay for cam etc plus hopefully 48mm jenvey heritage itbs when they released in late July.
May be overkill but if i dont have to pay the money back then who cares lol so long as house repairs dont interfere with my plans haha
 
Edit : although the 165e cam looks good, it's a hold... sorry cant say it lol still a chance ill ordet it instead though. Need more whiskey to decide

XC & XE factory manual only lists one cam specs for 302 & 351,

84DA block should have a 92mm single piece rear main seal, 83 2piece rear main, rest should be same.
3 or 4 bolt balancer is for P/S pulley (xc-xe 3 xf4)
Looks to be factory water pump after market would be GMB with pressed plate impalar rather then cast impalar.
Timing chains stretch is common,
If using a melling oil pump use base plate from stock pump.
What's the plans for the build

230/236 553/556 cam looks alright,
if looking at Crow I'd lean towards 14672 280 231 550" 108LSA, instead of 14650 292 230 522" 113LSA
just looking at NZ cam grinders, Auckland cams has a master No. 167 HYD 290/290 230/230 553/553 110LSA & 582 HYD 293/293 234/234 555/555" 108LSA
Kelford cams have SX165-D 270 225 541" 110lsa & SX165-E 280/280 230/230 560/560" 109?LSA(both part numbers is for a 253/308 cam but will be able to grind for a crossflow)
 

I'd look at a Quick Fuel Slayer 600 VSF over the holley,
has sight glass in fuel bowl, changeable air bleeds, rear jets, down leg boosters & VSF model has side feed fuel bowl (better fuel supply)
Holley has fixed air bleeds & no rear jets
Is $494.64 at VPW & will need something like a PFEFS2196S fuel rail.

last time we measured our 351 Clevo we got 65 litres per 100 k's, is that OK?
