If you are looking for high 10 performance capability for serious street use, here are a couple things to consider:
The front mount won't help you, it will hurt you IMO. I went 10.80's with a CAS V-4 stk location, and tried his front mount. It didn't go any faster, but ran the motor 8 degrees warmer & took a lot longer to build boost. 2 very bad things for street racing.
Get the biggest stickiest rubber you can fit under the rear, and get an extra set or two

All the power in the world is no good if the other guy has more traction. Maybe get a spare set of street drag slicks for those serious nites
I am not real familiar with the 50 series turbos & keep hearing bad stuff on some of them. I would go with a TE-61 for awesome low 11 to low 12 zone & great daily driving. If you got to have that "10 something" & it will be set on kill most of the time, go with the TE-45A.
Consider your fuel & tuning too. Even with alky & the power plate, you need a lot of motor to run 10's with pump gas. I can only assume you plan to run race gas on those nights of serious fun. That makes for a lot of tuning back/forth headaches & hassles. You may be a lot further ahead to build a solid low 11 performer on pump gas & leave it alone. Safer & higher fun/stress ratio
Girdle is a must for the 10's, unless you only need one pass. I did it without, but it stresses things & my car was lighter. Speaking of, generally a 100# is a tenth. Of course if you take (10) of the 100#ers (1000#) off a 3500# car, it would weigh 2500#. That *should* equal 1 second, which would turn a 12 sec car into an 11 sec car. Guaranteed if my car weighed only 2500#, it would go a 9 sec pass. It is a rough guesstimate for sure, but it definitely helps out on the ET & stress reduction for driveline. Any weight savings is a big helper.
Stock internals are fine for high 10's. A cam & valve springs would really help. I wouldn't stress modding the ECM for 55# inj's either. That's what I ran street/strip, never had an issue, not a big deal. Red Armstrong does this all the time, works great.
Hope that helped. The guy who bought my car had to see it run a 10 so he could brag to everyone about owning a fast car. He made me de-tune it, put a smaller turbo on it, and now it sits. Last I heard it had 250 miles in over a year on it. Doesn't race it, no full throttle playing because the tune isn't there for pump gas. Couldn't get it under 22 psi with smaller turbo (TE-62) and big flapper on the DP. All said & done, it would be a lot more fun with a 49 or 61 turbo & 009's. Got to be realistic & true to your goals.
Have fun!
PS- A
TRUE low 11 sec car on the street will beat the **** out of most anything out there, & be a BLAST to drive!
