So I have resolved on the 3x00 swap...
I'd like to compile a list of parts/gaskets/modifcations necessary to complete the swap.
I will also have many simple questions along the way that I hope you all can help me with. We have lots of time before I actually start buying anything which gives us lots of time to agree on the right parts![smile](https://www.60degreev6.com/vb5/core/images/smilies/smile.png)
This will be going into my 93 3.4 Firebird with 4l60 (non electronic) transmission and obd-1 swap (7727 Ecm with $a1).
So for what I know so far (and i will update this list accordingly as we figure things out)
RED = Purchased
Parts:
- 3500 heads (Built with ls6 springs, ls1 seats)
- Stock 3500 1.6 ratio rocker arms
- Custom pushrods (in correlation to my custom cam) (.451/.456 - Dur @ .50 224/230- 109 LSA) (From Wot-tech)
- 3500 LIM (cleaned, tapped for CTS)
- 3400 UIM (cleaned, lettering shaved off, back of intake shaved as well to deter rubbing against the cowl)
- TCE 59 MM Throttle Body w/ red anodized throttle plate (From TCE)
- 3400 Fuel rail
- 28 # injectors (From WOT TECH)
- 3500 Valve Covers
- Longer Throttle Cable (?)
- 3500 Head Bolts (From advance auto)
- 3400 EGR block off plate (From WOT-TECH)
- 3500 Spark Plugs AC Delco (From advance auto)
- 3500 LIM bolts (from advance auto)
- 3x00 TCE Billet Thermostat Housing (from TCE)
- 3500 thermostat 185* (from summitracing)
- PCV valve ( from Advance auto)
- RWD CTS - 2 wire and single wire.
- 3400 adj. FPR
- Stainless Steel Allen Head 3400 bolt set (From TCE)
- Valve cover breather filter
- Billet "3400" Oil Filler Cap (from TCE)
Gaskets:
- Stock 3.4 (iron head) head gaskets
- Stock 3500 header gaskets
- 3400/3500 top end gaskets (metal fel-pro versions)
Modifications:
- Tab on top of TCC must be cut off to allow space for 3500 LIM
- Alternator shaved a bit to allow proper fitment of valve cover
- Accessory brackets modified to allow proper mounting to heads
- LIM drilled and tapped for CTS (2 wire?)
- Drivers side Head drilled and tapped for CTS (single wire)
- 3400 UIM Lettering shaved off to allow fitment under cowl
- Modify injector harness (?)
- Pacesetter headers need to be modified to fit 3500 heads (bolts holes need to be slotted)
- Heater core hose modified and routed to the back of LIM
This is just an example of how I would like to go about this list. As you guys help me figure things out I will update the list. I know there is some obvious things that you guys can point out to me right off the bat.
