dcairns 8 Posted January 1 Report Share Posted January 1 Stock HP is 345. The stock transmission is marginal in the first place. If yours is still original (not been rebuilt) and with that many miles, you might need a transmission rebuild in the not too distant future. Adding 125 HP to my 03 SS with a Radix Supercharger, caused the stock transmission to wear out at 70k (installed the supercharger at 2,500 miles). That should give you some idea about what you can expect from the transmission. 1 Quote Link to post Share on other sites
Bgreenard 0 Posted April 3 Report Share Posted April 3 In stock for, you are putting approx 280RWHP (345HP is crank I've done all of the mods mentions but I warn against the BTR Stage 3 unless you don't mind less daily drivability. I agree in a trans rebuild with a dedicated trans cooler. I've had my SS for 12 years and had to do the transmission 3 times and considering a 4th rebuild. Good luck.
