Ha, I'm going the other direction, I'm approaching a point where I'm making more money working than I save working on my own cars. I'm thinking in another year or two I might shop around to have someone do an LS swap in my '85. I love the car, but I only get an hour or two every other week to work on it.

I may have missed it, but what accessory spacing are you using? I saw that they are a custom arrangement. I guess I am just asking what balancer fit? Truck? Fbody? Vette?
Did the rack you installed give you any more room in front of the engine?
Sorry for all the questions but I like the way it sits in there!

Did you have to change the drive shaft length? Or does the auto or manual drive shaft have enough slide yoke play?
Also, how much room do you have from the intake to hood? I am just wondering how much I need to raise the hood cowl on mine (Edelbrock Pro Flo XT).

Haven't got to the drive shaft yet. More than likely I'll make a new one.
If you can give me a couple weeks to get the front finished, I can give you some exact measurements. That's a tall intake and moving the engine forward will make the front of the hood worse. How much taller is it vs stock?

I spoke with my mechanic, there are two reasons the PVC routing isn't an issue in my swap:
Their mounts position the engine further forward than other mounts so there is a bit more clearance.
The LS1 & LS3 PVC routing are different. I'm fuzzy on the details so will say no more.

The LS3 PVC setup pulls the pressure not from the valve cover, but from the Valley cover. This is the cover that resides under the intake manifold, and sits between the 2 cylinder heads under the plenum. GM instructs the left side PVC port to be capped off. If your running an LS1 set up you can upgrade to an LS6 style PVC system by replacing the valley cover.

I built a LS1 up to 430HP, one issue i had was the small diameter LS1 MAF. I went to an 6.0 L truck MAF and it made a huge difference above 4500 RPM. I already put a larger TB before I changed the MAF.
