I don't think the sumps are interchangeable at all between the 2 engines. Ask Tim (p100ute) he knows the answer because he has looked at it.

Not yet sorry mate, have been sidetracked with the speedway season about to start up again, the off season went really fast and I have a long list of things to do for a few cars this year

So how did the old girl go mate?

Yeah I didn't supply or install the springs, the owner did when he got the heads back, the cross sectional area I ported to suit 7400rpm so I was surprised when it fell over earlier, now we know why

The XL run down the strip on Wednesday, 11.6 at 114mph, a problem has been discovered, the valve springs that got put in are only 110lbs on the seat which isn't enough for the roller cam, a change of springs is being done soon. We thought the headers were limiting the revs and power it seems to probably be valve float so more power to come from this nasty little 302.

I'm interested in this roller bearing idea Tony, we have to use the XE dizzy in street stock.

The theory is sound and works BUT the amount of data needed to get it right is huge. You have just as much chance of finding a suitable single/dual pattern cam profile as finding an off the shelf "scatter" cam that suits your engine.

I hope he runs quicker than 12's otherwise he might be a bit disappointed

Yeah I'm poor too hahaha, that's why I spend my time trying to find cheap horsepower.

That's awesome Jase, must be time for port work then

Thanks for road testing the idea wagon, it's one thing to show improvement on the bench but a test on a road going car is awesome, we found on the race car it wanted to keep pulling higher in the rev range like you described, goes to show the stock housing is holding them back.

The bonnet would be the limitation mate.

Thanks mate, just saved me time looking for these

There is a GM truck element from K&N that was perfect but I can't find the details, it was 12mm taller than the stock XF element.

Probably both, mainly it opens up more surface area to draw air from. When I just removed the rubber sealing ring from the edge of lid it didn't sit any higher but flowed more air because it could pull air past were the sealing ring used to be, so that tells me that the housing in stock form is very restrictive, you can feel a lot of air being pulled through the small gap so raising it further was the next step. The best thing to do would be to find an aircleaner element that was slightly taller but the same circumference as the original, that way you would get the extra height and extra element surface area.

No worries mate, I'm actually going to start these heads today LOL

I did some flow testing today with the aircleaner lid like talked about before, in my opinion DO NOT RUN THE LID UPSIDE DOWN. First pic is the test with the lid the normal way with the rubber sealing ring removed. Then with lid flipped upside down. This doesn't seal very well against the element anyway so that's another reason I wouldn't do it, also the bulge above the carb that's pressed into the lid is now facing down and takes height away between the top of the carb and lid.

Here are some pics of the stock intake and exhaust ports. Intake Exhaust Chamber

Stock open chamber 2V's IN EX 050 30.72 18.77 100 60.46 46 150 89.86 71.14 200 116.8 89.58 250 144.57 104.35 300 167.29 120.14 350 182.56 130.33 400 191.22 141.57 450 199.82 149.04 500 198.32 154.82 550 200.49 158.25 600 201.49 162.6 650 201.46 163.41 So much of a muchness between OC and CC really.

Wayne Smith from "performance carb tuning" in Perth is the owner and the guy who put it together.

Hopefully today Tony

Wasn't too bad down here mate, first decent rain for a while, mostly on and off dribble for months.

Rear wheel as far as I know, comes up on the converter right in the fat spot.

How the fuck did I miss this thread??? Loved the old Beacon as you know so excited to see the new one coming along mate.
