bit of an update:

I have been hard at it with research, emails, and planning . If only I had a lot of extra $... everything would be happening this calendar year, but since I don't, I have to plan things out sensibly.

I have exchanged emails with Nyes engines, Ohio Crankshafts, FiTech, Racetronix, and a few others. I am pretty damn certain I will be going with a 406, 421, or 434 gen 1 SBC with the Holley Sniper EFI system and a nitrous plate. I can buy it now via credit card and some of my car-fund savings account, but I am going to hold off and see what else I can get accomplished in the meantime.

The transmission will be getting shipped out on Thursday for a teardown and refresh, along with upgrading it to the 750 hp level offered by ProBuilt automatics (i still have to confirm this with Dana, but it is my plan). Probably will take about a month for a tunraround, but thats ok with me as long as it is done the best it can possibly be.

Fuel system: Racetonix offers the FULL wiring upgrade kit that I would need, including relays, grounds, power wire to alternator etc. http://www.racetronix.biz/itemdesc.a...WH-005&eq=&Tp=
I checked flow ratings and horsepower ratings and I am confident that an Aeromotive 340 lph in-tank fuel pump will be just what I need for the 525hp +200 wet shot.

I will need to plumb in a separate fuel pressure regulator for just the nitrous feed line later on, but that is once the new engine and n20plate is in and operational. Much research has shown that my factory fuel lines do have the proper diameter and flow to support my upcoming fuel demands so the main lines under the car will be staying.
Also, to solve my infrequent fuel starvation(when racing only)issues I had a few options, but I am pretty sure I want to go with the Holley Hydramat product. probably this one: https://www.holley.com/products/fuel...s/parts/16-104
or the 15"x15" version. anyone have any input on this? the only thing I am curious about, is how I am going to attach it to the new aeromotive pump inlet...and how I am going to do this when the assembly is INSIDE the tank hole..?
Therefore soon i will be ordering the racetronix hot-wire kit and the Aeromotive 340lph pump and the Holley Hydramat. Anyone have any last minute words of advice on that???

Yesterday I ordered the Koni Yellow struts and shocks from Founders performance. They called me today to let me know the rears were out of stock for a few weeks, but that is fine with me. I went with the 3rd gen front struts and the 4th gen rear shocks because the 4th gen shocks are ON-CAR adjustable...where the 3rd gen style shocks need to be removed from the car for any adjustment.

My MSD Digital 6+ ignition box is at MSD getting tested and repaired.

I got one wheel fixed that had very minor curb rash on it, but it was enough to bother me. USA wheels in Fairfield NJ did it for about $160

I will be holding off on ordering a driveshaft, rear axle assembly, roll bar, wheels, tires, and instead leaving the $ in my car-fund bank account so it can go directly towards the engine payment.

I will be removing the whole rear axle from the car when I drop the fuel tank to upgrade the pump. I want to pull out both axle shafts and install longer wheel studs. For full lug-nut engagement, I still can go another 1.5 full threads...so I'd rather be safe than sorry and just do it. I think these are the correct ones, but i will double check my measurments:

I also emailed Josh at JS Perfrmance, but have yet to hear back. That is fine with me since it has been the holidays and people get busy.


That is it for now. If anyone has any input on the wheel studs, racetronix hotwire fuel pump wiring kit, aeromotive 340 fuel pump, holley hydramat, or anything else...feel free to let me hear it. I will probably order some of this stuff mid week next week.
