Hey Guys,
Looking to do an LS3 swap on my 89 Iroc. Anybody know of a good shop in the Michigan area that has done LS3 swaps?

I don't think he's looking to take out a second mortgage on his house for a Detroit speed LS swap. Lol

Thanks Guys. They are not too far from me. I'm considering sending it down to Hawks, but wanted to do some research around me

Neither of these options will be inexpensive. Both will do it right.

Dutchboys Hotrods. At least one employee has a nice thirdgen. And they have built several.

820 W Prairie St Suite B, Vicksburg, MI, United States, Michigan
(269) 823-2967

Katech. Several employees also own thirdgens.
24324 Sorrentino Ct., Clinton Township, MI, United States, Michigan

Re: Michigan Shops-LS3 Swap

Norris Motorsports in Indianapolis is very good and specializes in LS tuning. I did the LS swaps on my cars myself but had Norris tune them. I'm pretty sure they also do full swaps, might want to give them a call. Indianapolis isn't too far away from you.
