Where to go next? Low 11's high 10's??

How much cylinder psi would a 175 shot make ? the big block outer wall look awfully thin. My builder was pointing out the spots for me since I bought some power adder rods (molnar) just in case I wanted to go faster. But I don't know nitrous, how to do the timing retarding or want to try to find another 400 block. I'll leave it to the fuller wallet crowd.

NOS is not for everyone but its exactly the opposite of your comment about the fuller wallet crowd in my opinion, how much would you need to spend to go 1 sec faster NA on an already tricked out combo than with say a 150 shot, I wanted to run a 9 in my 440 Cuda as my ultimate goal, could only manage a 10.7 NA, to go 9.96 in my case I would've had to take the motor apart and change pistons for a lot more comp, run race fuel, re-balance etc. etc. A 2nd hand Kit and a bottle fill got me to my goal.
It doesn't matter how you do it, its doing it that counts. I wanted to do it NA of course first, I guess we all do. Get yourself a cheater or similar kit, read the instructions its not rocket science and do some research its all on the net if you look. Several ways to retard depending on jetting/comp/ fuel used as to how much.
NOS kits were rich (much bigger fuel jet) back in the late 80's I only came back 2>3 degrees manually with no probs but then I never got the full hp out of the hit. Generally 1>2 steps colder plugs non projected depending on your combo, a good additional NOS fuel supply, some ign. retard again depending on combo/hp shot is important and off you go. Any mopar perf. motor with forged pistons will handle a 150 shot with ease without melting anything down. If anything a 400 block is better to use as long as its not much more than .020 over generally but have it sonic checked if your that worried about it.
