Hey, I'm in Plymouth, Ma. Pretty close to you.
Few things to consider. These are just my personal opinions. If the car is only seeing mainly street, you would be more than fine with good adjustable UCA/LCA, good springs and shocks out back. This would be more than enough for you. I'm at 505rwhp and I run Team Z drag springs w/airbag in passenger side, MM adjustable uca/lca and Strange 10-ways For the money it's a great combo for me. It hooks and rides nice.
If you want to spend the $$ on a panhard bar and torque arm, which is awesome, MM has a dedicated spring they recommend for their torque arm.
As far as rear shock. It's hard to beat Strange 10-ways got the price.
Stock block 306, V1 T-trim, AFM B-451 cam, TFS Twisted Wedge, Holley Systemax, A1000, Snow Meth, TKO 600, Team Z, Strange, MM, Lakewood and Moser helps me go forward fast.
