What do you think of my combo?

I posted this in 5.0 tech but this is more classic oriented since this motor is going into my 68'

Here is my current combo which has run a best of 14.5 @ 96 on an easy launch

68 Mustang Coupe, 289, .030 flattops, 9.1:1 CR, stock rods w/ARP, Ported Windsor D0OE, 1.85/1.55, Crane 222@.050, .498/.498, RPM Intake, Longtubes, Bigs 650 DP, T5Z w/.059 OD, 9" Locker, 4.30 gears, 31 spline moser axles. full MSD.

Ok. so here is the combo I am building

306 roller, 9.2:1 CR, ARP everything, AFR 185's, Jay Allen cam: base specs: 218/224 552/541 114LSA, RPM Intake, 650DP, T5Z, 4.30 gears, 9" 31spline locker, 26X10.5 E.t. Streets, MSD.

Jay didn't give me full valve timing specs yet but from what he said his cam would outperform the XE274hr that I was going to run, he said it is less agressive but would increase the dynamic compression to ~165-170 psi and require 91-93 octane. I trust what he says but I was always under the impression that more power came from bigger a bigger cam.

I'm curious what you guys think my new combo will put down and how much I will gain e.t. wise, or any suggesstions before I finish putting the engine together. Goal starting out in this build was low-mid 12's.

thanks for the suggestions. the T5z has a 2.95 first and mine's built with a 0.59:1 OD so the 4.30 gears act very similar to 3.73's with a stock T5. Only real difference is 2nd,3rd,4th are a little steeper.

I figured I would trap around 105-108 area and that puts me at 58-5900 at the finish. I will switch to a taller tire if needed.

I'm not too worried about the compression, If I had the choice I would have went with different pistons with less of a dish but the AFR's have the smallest chamber's 58cc, so im pretty much stuck with that ratio. This was kind of a budget build, I had bought the shortblock for a good price and decided to build around that.
