just introducing myself im new to the forum obviously! i own a 98 suburban that i have a few things to like k&n flowmaster high flow cats and i left the stock mid pipes and i have a dual in dual out flowmaster super 40 and that is about it i also have a superchips programmer that i was mainly using for the transmission but i removed it and when i get home from being deployed im getting a custom tune after i get a marine intake (looking for one if anyone has one for sale) and long tube headers for the 5.7l. and when the motor goes out im probably going to do a ht 383 probably. but ive been doing a lot of reading on the lq9 swap if i can get a good price on one and including a rebuild for a cheaper price that the 383 i might go that route just the wiring looks crazy!!! well ill see you guys on the thread im looking forward to it!!!
