I agree with James and Justin, go look at 5.8 prices. a VMP Gen 3 and cams will make way too much power. shit mine blew up with a shit tune and stock blower.

The Gen 3 can make 700hp or 1100hp. 700-800hp isn't any more dangerous than power made with a Trinity. It'll also make the power more efficiently, with less belt slip and boost loss at the top end of the rpm range.
Exactly, and without a built motor, the stock 2.3 will make enough steam for 800+rwhp, so there’s not a need to swap blowers just yet. The Gen3 will make power with less boost, but that’s a big cash outlay that can go to better mods for now.

I understand the price issue but to the guy above saying cams and Gen 3 will "make too much power" is silly.
I dont follow. Assuming you are running e85 or similar, gen 3 + cams in a 5.8 puts you at >1000whp. Way too much for stock lower. It would be fine on pump gas as you probably couldn't push it to point of danger for factory rods. A total waste to run that set up on pump but likely safe.
You can make shortblock killing power on the stock 2.3.
A proper combo on a Gen3 would be safe at 700rwhp.
And still support 1000rwhp when maxed out.

You don't magically install a blower and cams and make 1000hp. You can run a larger upper pulley and even stock crank pulley and be right around 750-800whp. You dont need to run a 2.4" upper and 15% lower with all the timing that E85 allows. With using a huge upper pulley on a Gen 3 vs a tiny upper pulley on a Trinity, the Gen 3 will run much cooler while providing more power and no boost bleed off like Trinity blowers do.
That's one of the many reasons I went with the Gen3 TVS, I make more boost and power with a 2.6 upper on the Gen3 vs a 2.4 upper on Trinity TVS. And the cams will make more efficient HP and make the engine not work as hard, as you have said, adding lots of timing on E85 isn't the best thing for the rods, keep timing conservative, run good fuel, keep boost around 16 to 18 psi with cams and you'll make 800whp and the engine will live a long happy life.
Boost vs boost, a Gen 3 is far superior to a Trinity. I made 60hp on same psi with same timing and same AFR with my stock Gen3 vs Ported Trinity with XBA setup.
What does this mean to you?
You can run 2-4 degree less peak timing on the top end of the RPM range with the Gen 3 (vs Trinity) and be much safer because of less overall timing. Timing is what will kill your rods so anytime you can make your air pump (engine & supercharger) more efficient, the safer the engine as a whole is.
For example:
Option A: stock Gen 3, 2.6 upper, stock lower, 18psi, 18 degrees overall timing, 780rwhp
Option B: Ported Trinity, 2.4 upper, 10% lower, 18 psi, 22 degrees timing, 780rwhp.
Chose option A. Less heat, more efficient setup, safer engine overall.

Hello everyone. I didn’t see all of the replies until now. I will update everyone on the current state. I replaced the fuel filter and it appeared to have been original and clogged. Priming the car now after the filter replacement sounds much healthier. I’m going to data log with vmp on the street before going back up on the dyno again.
There are many comments about enjoying the current power level, doing suspension, and comments about too much power.
Now I got this car because I like modifying these cars and it is fun. I am definitely responsible enough to control the power and future power.
Now as for future plans I have a lot of them.
I have full BMR Suspension in the works. Stage 1 of mods will be in next week which includes bmr lower control arms, bmr pan hard bar, and bmr performance springs. I have plenty more BMR goodies coming down the line.
I also have a set of LTH 1 7/8” Longtubes and LTH Catback on the way. I also picked up a set of L&M NSR Cams. I will most likely upgrade the oil pump gears as well while the cams are being installed.
I am also going to be installing the VMP Gen 3. Shooting for 800-900rwhp and a high 9 in the 1/4 mile.

Good to have you here Andrew. Actually watched that vid earlier.
Great list and order, starting with suspension.
There’s a few of us here that have already done all of that and more, so we’re trying to offer advice.
I’m just trying to remind you these aren’t Terminators. The stock shortblock, specifically the rods and oil pump gears, are on borrowed time at over 750rwhp.
Couple quick thoughts.
First, you like drag racing. If you’re going to drag race this car recognize you’ll need gears and a built rear.
I had FOUR sets of gears in my built 8.8s before I put a 9” in it. Run bias ply only at strip. Get a rear brace.
You’ll absolutely love 4.10s on the street with DRs. Still a rocket on the highway. 80mph at 2000rpm with 4.10s.
Cams—well they sound good and do make the motor more efficient, but you’ll extend the RPM range, the hardest on the two weak links, rods and OPGs.
I’d save cams for when you want to do the shortblock.
Until then, you can have a LOT of fun at 800rwhp.
Good luck.

I think may at least see LT dyno results before Andrew does anything crazy like swap cams or blowers 
.
The fuel pump maxing out early caused some weird dips in power in the graph, I was not happy with the VMP stage 4 power results. But once I found the pumps were maxing out at 5900rpm, I stopped pushing it.
We will do dual VMP boosters if needed, but its best to make the hardware right first, so hopefully the new filter has a big effect.

Quoted for truth.
Andrew’s in good hands with VMP.
Maybe we will run them at Mod Nats 2019!

Your car is going to be a riot to drive whether you're at the strip or on the street no matter which route you take. Just make sure everything else is sorted out before you get stupid with it. Sounds like you're heading in the right direction.

I would of went 2" headers to let her breath because of the boost. Also do crank sprocket with the OPG's along with timing component upgrades. I also would not bother with cams with a Gen 3 as your bottom end is already maxed out once you throw it on. At 900hp I would hope low 9's/8's.
Which reminds me, what does a 1k rwhp GT500 run in the 1/4? Not stripped racecar times lol

there have been full weight gt500s with the stock tvs blower into the high 9s trapping near 140. A 10% or 15% overdrive balancer with stock upper, 1-7/8 longtube headers, throttle/plenum, jlt big cold air, 4.10 gears, along with other supporting modifications. Times will be shaved of by light to moderate weight reduction.

If I was him I would just go ahead and work on doing a built motor before anything. Rods and pistons and a nice upgraded valvetrain and mild port job and let the thing keep trucking along to 1300rwhp+
Agreed. If he is shooting for that much power, it will be much cheaper to upgrade the parts now rather than after the motor blows. I am following none the less. It will be interesting how it all plays out!
you will have to hold that blower back so much it will be pointless. why spend that money on a huge blower and when the stock 2.3 can blow the SBE? money would be better spent on a good clutch and cooling. You've said it yourself plenty of times anything over 800rwhp on 93 is asking for trouble.. so if he runs E85 it'll be hard to bring that car to a safe power level. Just my .02.
