Finally, my first 360 and goals for it! I'll be asking a lot of questions.

I'm not planning on racing this car at all. I want to build a fun street driver. Gears will be 3.73 and converter will be 10" turbo action with 3000 advertised stall. I propably cant afford to send heads of to have work done to them. I could get help with porting though. We have good quality gas here. 98 octane and 99.
Nice. Port matching may help some. I tagged IQ52 for you, he's a true master builder, listen to his advice whenever chimes in.

If I may ask, why the switch from the 273?
