The one place in the rear cover area where oil
Is pressurized is the barbell. If you do go in maybe verify the o ring on the barbell is not cracked

Looks like that will be my next mod.
How do you think it will be compared to a long runner fast in the low to mid range for torque?
I saw a couple of dyno sheets of a prototype unit and it hardly loses any torque at all and above 4800rpm it out powers the long runner fast manifold by quite a margin.
I wonder how it would compare to the mid length runner.

I've put about 150 miles on the car with the new fast intake so far and I'm loving it. The car seems to drive alot better at lower rpms and I haven't retuned the car yet. Today I went and put the car on the dyno to see where I'm at.

The best run was 539/492, more than I was expecting. The car still has a stock ls3 throttle body and 1 3/4 headers with a ford 9 inch with heavy 20 inch wheels. Here's a picture of the graph.

Looks ok but I'm curious to see once it's had a full proper tune and see how it runs.
I would expect another 40-50rwhp -15% for the Australian conversion and you will be at 510rwhp which is about right.
Camshaft is a little conservative for the engine size but will drive well on the street.

That's good.
When do you think it will be finished?
Have you also got that new FAST LSXR intake on the engine?

Nice. Im running a very similiar cam in a 427 also.waiting to get car running and tuned first to decide if i needs more powa. If its slow, i ll prolly switch my set up to solid roller n order up a proper cam to match. Just gotta see how deep that rabbit hole goes from where im currently sittin.

Whats the verdict with the oil leak?

My car felt pretty powerful the first couple hundred miles, but now that I'm used to it the car didn't seem as it was. That's the reason I put it on the dyno just to make sure that it was running properly.

On the oil leak, I found that the fitting on the side of my catch can was screwed so far in that it was right against the filter element and was blocking off the dirty side of the pcv. After fixing this the car leaks less oil, but it still leaks. Im pulling the transmission to find out exactly where the leak is coming from.

Found my oil leak, it was the main seal. Replaced the whole cover with a new one with the seal already installed. While I was at it I replaced my barbell with a billet one.
