Ok, been a long time since I posted in here, but I've learned many things since then, figured alot of stuff out and I am formulating a plan for what's next.

Here's what has happened since the last post:
1. I redid the catch can setup and I could feel the difference in the upper RPMs and it now just catches oil, it doesn't mix it with condensation formed in the upper tubes. The rear tube (clear home depot one) is just a road draft style tube now.

2. I got a job, and got it switched over to e85. I made 363whp and 395 lbs of torque on monday, then the next saturday on MAP's dyno I made 20 hp less and 30 lbs less. Who knows exactly why, but I'm leaning towards a loss of head gasket integrity. It was spewing coolant out of the rad. cap on DB's dyno, and the clutch was slipping, so we called it quits that day. But now I can't get on it without having coolant come out from somewhere. I tried a new cap, and it just squirted out somewhere else.

3. I've parked it until I figure out exactly what was happening.

So with that said, here's what I have in store this winter:

1. The head's coming off anyway for new valves. And why not oversized stainless steel valves?

2. A new cam, either a 292 or 296 or combo of 292 intake and 296 exhaust. Both grinds provide .465" of lift, combined with my 1.4:1 rocker arms to equal .650" inches of lift, haha. I can has lopey idle? With this comes an adjustable cam gear and getting it all degreed properly.

3. Depending on what's reasonable and realistic, I may o-ring the head. It seems like all the 500whp and up g54b's are doing it. Just can't get their heads to stay clamped on the gasket well enough. I dunno.

4. new SPEC stage 3+ clutch good for low-mid 500 torque capacity.

5. bigger injectors. It's hard to make 500whp with 750's on e85. 1200's maybe?

So that's all I can think of right now, but I guess the stock tranny is like glass above 450whp, so I may have to get a supra w58 trans. I guy makes bellhousings that bolt to the wideblock and use the stock flywheel and clutch. but I guess when I get it all done and together, I'll buy a tranny blanket before a new trans. And for tuning, maybe put a 1/2" thick steel plate between the legs and the trans tunnel, haha.

I'll update as I purchase and install parts.
