well im getting two complete setups for 1500 I.just need somebody to put them in my cutlass and elco I budgeted about 500 for each car on labor to get them running and driving, what do u guys think?
The labor charge really depends on who does it for ya. If its a shop then its probly gonna cost alot more. Why dont you do the swap yourself and save the cash?

I hear ya on the wires and computers but if you have the full harness your not gonna be doing much wiring. Pretty much a power wire and thats it. Of course your going to need an electric fuel pump wired in but those are simple to wire up. If you can install a car radio I bet you can install the needed wiring for this swap. Assuming you have the whole harness.

People who say the opti spark is a continuing problem either don't have a clue and are repeating what someone else without a clue says, or they only messed with very early units. I have never, repeat never seen a vented opti fail as a unit at under 120k miles. Yes, you may have to put a rotor, cap and wires on it, but then again every other distributor requires that as well. Do not be scared off by the by the bs on opti spark, it's plentiful and uninformed. The failure rate on vented opti units is no greater than an HEI. :wink:

I hate to be a naysayer but I don't think $500 is going to get it done. If it goes to a shop it will cost waaay more than that but will probably be done correctly. If you can find someone to do the entire swap in your driveway for $500 I would be very nervous about the quality of the work. If your car has a SBC in it now I would estimate at least 20 hours to do the swap. These things will need to be addressed after the engine is bolted in:
-Fuel system (pump, lines, filter)
-Intake ducting (MAF, air cleaner, cold air piping?
-Cooling system (creative radiator hose combinations, heater hoses, heater valve, possible radiator upgrade, electric fan)
-Exhaust system (O2 sensor bungs, original manifolds or LT1s? headers?)
-Transmission (crossmember, cooler plumbing, shifter mods, driveline shortening)
-Electrical (Modified factory harness or aftermarket stand-alone? Wiring to the fuel pump, gauges, fan. How "factory appearing" do you want it?
-ECM reprogramming (delete VATS, air pump, after cat O2s, shift points.
-AC (custom hoses, wiring, recharge)
-PS (custom hoses, mount reservoir)

Kinda looks like the 400 was the easy way out :lol: . If you have the tools, skills and location I would suggest doing it yourself. The LT1 is a more direct swap than an LS but don't expect to just drop it in , connect a fuel line and a power wire and be on the road. I'm certainly not saying don't do it -- just be aware of what it really takes to finish the job.

Im going to get someone to look the motors over and look at my cars, the sbcs will be out before the job is started. so who ever does it will have a empty space when the motor arrives

I ound a certified tech at a shop that my cousin uses and he said that he would do it for 400 each car what do u guys think


I think that's unrealistically low.

The physical swap, wiring, fuel pump issues, exhaust issues, possible accessory relocation, all for $400 a unit? I can think of about a half dozen cars that will be in line if that's really the rate for all the above.
