Should I get a roll cage and how fast is my combo?

[Arekusu]

Hi All,

My project went from strong street truck to maybe more. I'm not certain as I'm unsure how it's going to preform. To my knowledge anything faster than 11.99 needs a roll bar.. but since I have floor patches greater than 2 feet square (I'm pretty sure.. kinda pushing it) I need a full cage. I was hoping to go 12.5 in the quarter, faster is ok, but will I be touching high 11's as configured?

Truck 1964 C-10 SWB Step Side (may get a fiberglass hood later)

Motor

454 .030 over Eagle I beams
Brodix race right oval ports 118 cc comb. chamber. 270 intake
Intake valve 2.25 Exhaust valve 1.88

9.5 to 1 compression ratio

900 CFM Pro Systems carb, Edelbrock RPM air gap intake

Cam specs custom ground from Bullet Cams
Hyd. Roller Cam
Intake Center line Angle - 106
Cam lobe center line angle - 110
Duration at .050 Intake - 230 Exhaust - 238
Gross valve Lift Intake - .601 Exhaust - .601


Tire height is yet to be determined, but I'm looking at anything from 29-33" tall and about 12" wide

Rear gear's also TBD, maybe 4.10's

I Have a TKO-500, but may be looking at a 4 speed like a stronger M-22 or a used / refurbished Jerico. No Auto's for me. Truck should weigh about 3800 lbs. from the last time I weighed it. Coil overs in the rear with heim joint track bars and adjustable brackets for up and down.

I took the cab off to finish painting the truck this up coming weekend. But I thought I should strengthen the frame some maybe for the big block torque.. that got me looking at roll cages.. now I'd just like to know maybe how fast should / can I go and do I need the cage? Thanks for the help in advance. I'm still new to this.
