Default Need Mod Advice/Suggestions
I reached 377 RWHP and want to break the 400 mark. Current mods are:

1999 Trans Am WS6 (m6)
LS6 Heads/Cam/Intake
Pacesetter Headers
SLP lid K&N Air Filter
P&P TB
That's all I had to get 377 RWHP

I recently purchased a Borla Exhaust, subframe connectors, rear lower control arms and a tq arm.

any suggestions to make sure i break the 400mark..?

Camshaft is probably the next move. You'll be spending $600 or so, but you can push her well into the 420rwhp range

Let us know if we can help you out on it!

i suppose you could buy a cam that doesn't require new springs.

hot cam or some of the ASA are low enough lift to allow ls6 springs.

An underdrive pulley and electric waterpump would get you really close but you'd be spending the same or more as a camshaft swap.

Yes, but I wouldn't recommend high rpm launches on it.
