89 iroc lsx swap
In about a month i'm going to be starting the swap. Right now the car is 350 TPI. Below is what its going to be. I'll post up pics and progress once we get started.
6.0L iron truck block and heads
Truck style coils
LS1 intake, injectors and fuel rails
4th gen exhaust manifolds
TH350 trans (I know not the best thing to use but thats what cam with the car when i bought it so i'm using it for now till i can find and built a 4l60e)
Thats all the major stuff I can think of right now. The motor will all stock, I'm hoping to put down 300 to the wheels.

Re: 89 iroc lsx swap
Good luck with your swap. 6.0L is a good choice and can net some nice HP numbers when tuned right. Depending on the miles, change the oil pump to something nicer (ported LS6) and upgrade the timing chain to an LS2 version. the TH350 is not a bad choice - they're cheap, sturdy, and readily available. If my 4l60e goes south, that's my next choice.
and make sure you get pictures!

It is the only way to go for a street driven third gen with power and budget in mind. Mine screams and is always getting faster.

Thanks guys... yeah the motor is all apart right now, i got it off a buddy who was in the process of rebuilding it for another project but lost intrest and sold it to me so pretty much every thing engine will be new.

Re: 89 iroc lsx swap
Going to be starting the project this weekend but I think I may have over looked one key part. Is it possible to reuse all the stock third gen stearing components including the pump?
Thanks,
Thanks,

Re: 89 iroc lsx swap
don't know of any way to reuse the factory pump without doing a bunch of custom bracket work. best bet is to grab a ps pump that matches the accessory setup you're working with (in most cases its an fbody pump). pressure line would be the 4th gen one and the return is just regular cut-to-length ps hose
