Default Whats my next step?

I want to go a little faster. I have (not installed yet) complete suspension, front and rear shocks and springs, panhard bar and lcas all with roto joints, weld in subframes, front and rear sways, and an adjustable tunnel mounted torque arm...also assembling 3.90 rear end which may suffice for now as far as speed goes (i had 4.10s but ring gear bolts backed out and went for a ride through the diff cover). I have full bolt ons and i was thinking the only thing to add some power would be 1.6 rocker arms with nice springs that I can also reuse when I do heads and cam in a year or two...other than that what can I do to go faster? Don't wanna do too much weight reduction, I like my interior, and the wife wouldn't go for n2o lol.

Toss on all the suspension and spend the season learning how to launch the car well. While your doing that save for a proper rear end.

If its an auto car, a torque converter is a nice wake up.

Not that it makes a whole lot of difference but I am using a solid pinion spacer and a diff cover with bearing cap supports for a stronger rear. I need this 10 bolt to last me a long time, doing a 9 inch when I have the time and money to build a 383, which I'm thinking is going to b 5 years minimum, I understand hard m6 launches kill the 10 bolt so don't want to do that too quickly! I'm hoping I get lucky with this rear and it holds up to my moderate abuse

Haven't taken it to the track, just street runs, no times, mostly in Texas on the open roads, I'm in ct now though so not to many places to test run

So would I gain a good bit with new springs and 1.6 rocker arms? I figure i could reuse these parts when I do my heads and cam

You will get gains, no doubt about it, but as to how much fast you will be is hard to say. It would be easier if you had track times and mph to measure by. I don’t think it will be noticeable by the seat of your pants.

OP as long as you don't try to launch hard on Drag radials or sticky tires your 10 bolt "MAY" live for a minute, I have a 97 SS M6 and when my car had boltons (headers, 1.6 rr and springs, 52mm tb, under drive pulley) Torsen diff with the AAM cover Richmond 4.10's and Drag Radials I broke the first set of gears at the track. I had to replace the torsen with a Detroit Locker, Moser axles, solid pinion spacer, T/A girdle and Motive 4.10s, the gears broke a tooth just pulling away from a stop light!!! I replaced the diff and gears once more then I sold the rear before it broke again and I got a Strange S60 rear and I have never looked back.
It doesn't matter what you do to the 10 bolt, it won't last behind an M6 and any sort of power/torque/traction.
