Wanted to show you all my project. I have had this truck for 10 years. It was my daily driver through HS and College both. Treated me well and never left me stranded. I felt it was time to pay it back with an LSx swap.

I found a 5.3/4L60E combo at the local salvage yard with 93K miles on both.
The swap is coming to an end. I am keeping it stock for now to get a base line of what I have for now. It is going to have a Custome EFI live tune, as well as home made cold air intake, with dual exhaust.

I have been troubled with what mufflers I want to use. Not using cats I worry I am going to have a redneck TBI truck glass pack sound. I have down pipes off of a 6.0L they are 3", I have to 3" 4' long tubes I plan to weld to the down pipes to get me back behind or under the cab. I intend to put an H pipe in before my mufflers. But what mufflers should I use? I really like Magnaflow, but there again, with out cats may give me that red neck sound i don't want. I have thought about Magnaflows and Aluminized packs together.... I just don't know. Flowmaster offers 2.5" manderal bent tail pipes I can get from Summit for $105, they dump out behind each tire,

Any ways, here are some pics of my progress.

 

Do I see a sleeper being born?

I'm looking forward to the day when I can repay my truck for its service. Keep up the good work, and keep us posted.

I'm curious, what did you have in it before the swap?

 

Nice project looks like you well on your way!

 

Do you plan on putting a cam or anything in it?

 

I hope its a sleeper!

I had a 300hp or so 350 in it, .030" 9.5:1, edelbrock Perf RPM cam, springs and intake, 625 Road Demon carb, MSD HEI dist, and a 350TH with a transgo shift kit, TCI saturday night special TC. Still have it, keeping both for a future Hot Rod. My son is 11 months old, Hope to have that project by the time he is 6 or so.

 

As of right now, no. If I do anything along that lines, I'll find a 6.0L for it and build it up. But you never know, I might get a wild hair next winter

 

sweet, good luck with it. i have old flowmasters on mine and it sounds good. they are dumped just before the rear axle, but i plan on having an x-pipe installed as soon as i can.

 

jshouse. Do you have any more pictures of your truck? Any engine bay shots?

 

uploaded some pictures tonight from my camera. Enjoy

 

I went with full 3" exhaust and used a H-pipe in mine. At idle it has a deep throaty sound to it. I think you'd be happy with the magnaflow though. I have a friend that just put headers and ORY on his Dodge with a magnaflow and it sounds good.
Your swap looks like it's going good. Good luck on the rest of it.
