I started my installation today... Have most of the old exhaust removed. Found a broken header bolt on the drivers side. Hopefully I should have the drivers side installed within the hour.

particularly if it goes on a OBD2 controlled motor. with all the extra sensors involved, more air = more fuel in the engine.
making the engine turn easier is the key to HP and economy, yes. but, with newer motors it is very difficult to fool the paired engineering and computer programming to get you better

- DPF Delete to improve fuel economy... I'm worried about passing emissions and if its even worth it, or just install all new larger exhaust system?
I'm thinking about swapping a 6.2 diesel for my 350 in my 79 k25. I'd like some input on expirenice with these engines and some number ratings my 350 has about 245hp 310 footlbs torque. Behind is a zoom ceramic disc clutch then a nv 3500 married to a 208 with 4.10 rears... And before I get ripped on about the Nv3500 I'd like to say I beat the snot out of my drivetrain (ex. doing burnouts in second gear at 5 grand) and she's still holding strong.. Overall I'd just like some 2 cents about this idear.
