Have you ever heard of D & P Torque Converters?

Do you know for a fact that you need a 3500 stall converter? You've not given much information as to what exactly your setup is as far as engine improvements, diff. ratio, tire size etc. are particular to your car.
Check out the information sheet that TCS(www.tcsproducts.com) wants you to fill out before you order a converter, and the questions on the information sheet are the same as any quality converter builder will ask you. You can't just say I want a 3500 stall converter and expect a stock or slightly warmed over engine to work properly. That's like throwing a Dominator carb on a stock engine. Sounds great when you tell your Buds about it, but runs like crap.
Don't throw your $$$ away on something that may not be what you need.
