s10 ls1 guys......
New motor/Transmission or take-out?
Carbed or Injected?
You doing the work or farming it out?
Reusing the stock 4.3 radiator or custom cooling?
There are a lot of variables, each of which may significantly affect the price.
Are you saying that "you have a 99" and want to know what it would cost?
2wd or 4wd
What trans?
What motor (LS1 / 6 / 2 / LQ4 / LQ9 / LM7)
I've got $7k+ in my '99 Bravada conversion. But that includes the engine (6.0L LQ4), trans (80E), new tcase (NV146), new harness & programmed PCM. Basically everything from the radiator to the rear driveshaft was replaced. And I haven't got to changing the rear end or having a front driveshaft built yet.

Find out what the estimated shop labor rate is in your area.
Multiply that by about 80-100 hours (depending on the experience of the shop)
Calculate the cost of the harness ($600-750)
Cooling system
Mounts/Exhaust
Somewhere around $10,000-$12,000 for a basic job done in a shop.
Just my estimate.

I'd say double that or more if you are taking it to a shop to get it done.
If I was your dad, I'd do the swap myself or buy an F-body.
I really just can't imagine spending 15 grand or more for a basically stock ls1/rear end swapped S10 install.
But hey, your dad probably has more money to throw around then an 18 year old like myself.
And headers?? ...how do you clear the steering shaft....mine practically rubs on the stock manifolds heat shield...
You guys are great..thanks for the help!!!



As for headers, mine just have a very slight indent for where the steering shaft gets close. It is still very close, but doesn't rub at all.
