Yep - with Aussiespeed making the blower manifolds and stuff to bolt them on I had to be part of the action.  I know many have done this conversion themselves.  I want to see for myself how easy it is with the Aussiespeed components. 
 
The old crow camshaft I have, used to have in its blurb that it was suited to supercharged or nitrous applications.  Not real sure about that given the lobe sep but hey why not.
 
I want the ute to tow the skid car and what better way to get good low down grunt than a low mount supercharger.  I have a good open chamber head here with mild porting so I will use it and a set of old 235d springs from the race car.  With a suck thru 600dp and manual shift it should be a fun shop ute.
 
Wonder if it will turn the tyres with the trailer attached?

Thanks men.  Just got back from 9 days in the bush.  No phone service - No screens - nothing.  Just the camp fire, family and friends and of course motorbikes and buggies.
Bloody awesome.  Having the rest of this week off (tville v8s) and then back to work next week.  Need to make some serious progress on this ute and then burnout ute in time for Tropical Meltdown in August.  Busy times ahead as usual.

Yep lot of satisfaction in 're-using' thrown out stuff.  Love the work

That is about all I have for today.  I have been flat out on the panel side of the shop ute but I am aiming to get the short motor together on Saturday. 
 
Does anyone want to see a shot of the sump I will be using?

Bring it down to NSW and Ill be in charge of marketing sales and beer.

Well the engine that came with my new shop ute has a munched cam bearing (number 2) so it is time to finally put together the 'Mad scientist' crossflow.  This engine will be pieced together from left over crossflow bits from my speedway career and general hunting and gathering.
 
Here is quick run down;
 
Yella Terra street terra bolt on adjustables on a D head with moderate porting and a multi angle seat cut.  Not really sure on the head flow figures but the engine it was on made 270rwhp on fuel so good enough.
 
Bottom end will be a 78DA block, .030 that I picked up locally for $20.  It is honed and fitted with new cam bearings and the crank is unbalanced.  Slugs will be ACL 8.5cc (now 10cc thanks to inlet reliefs) 200 rod pistons on balanced 200 rods with ARP rods bolts.
 
Camshaft is a very old CROW 619 Hydraulic.  Not ideal but it is what I have and I want to finally use it.  I have a new set of Clevite anti pump up lifters so they will go in with a one season old Rollmaster Double Row Timing chain.  Pushrods will be a set of tapered XC factory units (they are strong little buggers).
 
The Shop ute cam with off the shelf Lukey extractors and I have fitted a press bent 2.5" exhaust with a singe muffler (no resonator) that I had lying around. Compression should end up at 10.3:1 and I will be running an Aussiespeed 2 barrel manifold with a Keith Dorton 350 Holley initially.
 
The plan is to build and run the engine like this and once it is 'run in', I will dyno it and see what we end up with.  Then I will change to a reco 500 Holley and see what happens on the dyno. 
 
I have a dirty old CAIN four barrel manifold here and a 600DP so that will also make it's way on in the future and if I can con a new Aussiespeed 4 barrel out of Mark I will test them back to back to show how superior the Aussiespeed unit is. 
 
Whole object of this engine is to show people what can be achieved with careful parts hunting and scavenging.  It wont be an all time horsepower king, but it will be fun.  I will update this thread with results so stay tuned.

The Wombat raced again at mt barker yesterday and had a great run, finish 2nd in all 3 heats to qualify outside pole for the final, then goes and WINS the final, yeah boi pretty pumped about that

Good stuff sean.  car is showing good pace.  I'd say the final tenth or 2 will be found in set up.  His km/h is right up there.  More seat time and a gun set up and you guys will be smoking them. 
 
Best of luck on your health.  I'll keep the x-flow fire burning whilst you are laid up.  Got a big couple of weeks coming up assembling tough cross flows.   

Thanks mate, yeah I can put more timing in it still and the AFR's are in the high 11's so I can still take fuel out for more power later, hoping to get her on a dyno soon to get it Mickey Mouse.
I'm looking forward to surgery to get started, I have at least 3 to get through but as soon as I'm recovered I will be full steam ahead with "stumpers heads n manifolds" engine developments

I thought I would start a separate thread for the head port I'm working on for the race head I'm going to be doing for a proddy speedway car.
This port is a C1A casting, and the results are using a stock standard crossflow intake valve, 1.8in single cut valve. The port has a 3 angle seat cut that is a little worn but still usable. So the first test was on the port as cast from the factory with the 3 angle seat cut, the second test is with the port ported and the third is with the port work plus the chamber work.
 
this is the stock valve I'm using
 

 
Stock combustion chamber and reworked chamber, not much needed here, just laying the edge over and blending to form a nice smooth shape, you have to take the point off the end of he swirl generator to stop pinging.
 


 
This is the port work, hard to explain what I have done but most of the work is at the short turn and bowl area, I mapped the air velocity of the stock port to determine what material and shape needed to be used, the port responded well to being biased to the right.
 


 
Here are the results
                     test1        test2        test3
50                 29.4         30.95       36.08
100               54            58.34       63.15
150               77.4         85.6         92.5
200               98.5         108.98     121.92
250               121.2       131.56     149.84
300               141.4       151.05     165.2
350               162.9       168.79     178.97
400               177.7       180.13     190.17
450               184.4       189.02     198.22
500               186.2       197.22     202.96
550               189.1       203          207.93
600                               214.2       213.98
650                               213.44     213.4
700                               212.16     212.2
 
 
So as you can see the results are reasonably good, the chamber work plays a big part of the power potential, this head now has a flow potential of 330hp using the stock standard intake valve.
Hope you find this interesting.
