    Hey everybody, I'd like some feedback on some questions I've got here , opinions are fine ,real experience would be great! Here goes- I'd like to swap out a tired 305 for a gm crate 350 , do I have to change my ecm chip? injectors on the tbi ? anything else you can think of that may cause me headaches? Also, I was thinking of running 33x10.50's on the front and 33x12.50's or 14.50's on the back, mostly mud and snow play up here, any thoughts? Finally, my floor is giving out under the back corner of the drivers seat, know a good place to order a floor or sections of? thanks CHEVYS EAT FORDS AND S_ _T DODGES !
