Well I'm planning on taking a 406 Small block and a TH350 and replacing my 5.7 4L60E in my 1999 C1500. I'm working with a shop on the swap, I want to make sure I have as many parts purchased for it ahead of time as possible.
I understand how many of you may consider this an enormous step backwards, consider my position. I have a brand new 406 that's built pretty stout. 230cc iron heads, roller rockers, big valves, 525 lift, 244/248 @050 (thinking about a cam swap), can't remember the compression exactly but it needs 93, and mix in the summer or timing pulled. The TH350 was built to suit the engine, 9" stall. The engine was a driver out of my previous project, a 1978 Vette that my dad and I worked on. Ended up keeping the motor and trans, sold the shell (Dads least favorite vette, didn't feel bad selling it.) But I wanted to keep the drivetrain to keep Dad with me project to project, if you know what I mean. We'll my grandfather passed and I was blessed with a pristine 1999 C1500 ECSB White, tan interior, never smoked in, 103,000 miles and a hypertuner sticker in the door.
Well the truck is shifting hard 1-2, and I have this drive train just sitting there begging to run in something. So I'm going to marry the two, and maybe make it into a show truck with a story one day. I've purchased several parts already listed below.
RC 2/4 Drop kit w/shocks
18x8 Rocket Racing Booster Hypershots
245/50r18 of some flavor
10" Punch p2 under seat
400w Fosgate amp
UTE-73BT Alpine headunit
1 5/8" mid length headers Jegs brand I picked up at a swap meet. Probably going to wrap them.
So my plan is to work with a shop to retain as many creature comforts as possible, cruise, ac, gauges etc. while they handle the swap as I just don't have time. I'm not thinking there will be many mounting issues since it's a small block coming out and a small block going in, the 4l60e getting replaced by the TH350 I think should be as simple as elongating some holes and maybe a new driveshaft. But as far as gauges and wiring go I have no idea and will be relying mostly on their knowledge and wiring diagrams. Any and all input is appreciated!
Last pic for inspiration, I know he's lower than 2/4
