Not your average LT1 :) LT1 240sx

LT1 intake manifold. It's getting painted the stock Nissan red color from the s14 240s.
BUT..... Ran into a little problem today.
I got the wiring issue resolved and took it up to the machine shop I work at to let my boss check her out. Everything was going great, probably had 20 miles on it by now, did a nice burn out leaving the machine shop, etc. I'm almost home and I'm going down the hill toward my house decelerating in 2nd. I decide to romp on it and I got going a little faster than i wanted and started breaking while the rpms were still dropping. The brakes on this thing are real sensitive, the front bracks GRABBED and the car decelerated real quick, I got that holy **** this thing can stop feeling. Well I made it down to my garage about 100 yards away and while I pull in idling I hear a knocking and squealing under the hood.
Pulled the engine, 2 spun main bearings and one spun rod bearing and a bunch of about to spin rod bearings.
I put a lot of effort into oil control when building the pan but focused on side to side oil control, the pan has a 45 degree slope upwards facing the front of the car from the bottom of the sump. The quick decell and the fact I was allready going downhill shot enough oil up to the front of the pan to uncover the pickup. I'm sure it had no oil pressure for a good 8-10 seconds and I was braking while the rpms were still falling from 4500+. All that adds to to some not happy bearings!
So the pan is getting reworked with a trap door and baffle taking decelerating into consideration. This was my fault because of the flaw in the pan design. I donated a stock lt1 shortblock I had laying around to my buddy and were swapping all his stuff over to it. I'm about to get a few hours of sleep now and were off to summit around 10 to get some gaskets/ misc stuff we need. Hope to have her on the streets and DONE by the end of the weekend.

Hey I know I didn't give an update and I lack more pics but I've been really busy! We got it wrapped up a few days after the oiling mishap and he's been driving it since. We went to a small car meet in pit before Christmas, here's some footage I caught of the beast.

Here is all the good pics I have from the bugining of the build until completed. It still needs a few things like a niver radiator mount made, and the heater core hoses run on the frame rail now instead of beside the intake manifold.

POR15 is the non high temp stuff. It is baller. POR20 is the high temp stuff, and while it works great on exhaust and high heat stuff OTHER than the headers, I have not been able to get it to work on headers. No matter what prep I do it always bubbles off in certain parts. The parts that don't bubble off on the first start are not coming off at all though. This last atempt I tried heating the whole header up with a torch to try to heat out any impurities, then used acetone for the final wipe down. They had the worst bubbling yet lol.
