This is just a thought, but a serious one nonetheless, I am considering this, I have thought of what needs to be changed, please let me know if there are other things that I need to consider:

Different motor mounts.
Different hood, I know that the LS1 motor sits higher than the LT1's.
Different computer, and new bolt-ons, everything required for an LS1.
Different wiring harness.
Change front springs & shocks.

Here's my questions, is the front end suspension, ie. A-arms, K-member the same as the LT1's?

How's about the tranny? Will I have to purchase a new 6-speed? Is the Hydraulic clutch assembly the same or will have to change that as well? If I have to get a new tranny, will new tranny mounts be required, or do they use the same ones?

 

You might want to do a search on LT1 Tech... I know I've answered this one a couple times, or at least contributed to the thread.

LS1 K-member is different.

LS1 T56 is different - longer input shaft.

LS1 clutch slave/master is different - slave sits concentricly around the tranny input shaft

LS1 clutch is different - its a conventional "pusher"

LS1 radiator is different - its "conventional" flow

LS1 radiator support structure is different

LS1 needs a higher fuel pressure - 58psi

LS1 has a different fuel supply strategy - dead-ended supply, with pressure control/recycle from the fuel filter.

Moving to "LT1 Tech".......

 

youd be better off in the long run putting an lt1 (if its a v6) or building the lt1 you have, than trying to put an ls1 in the car.

 

its a z28, therefore its an LT1

 

The money would be better spend building up the lt1

 

Just work the LT1, putting an ls1 in is not worth the hassle.

 

for what it would cost build your engine for FI and put a blower on you'll never look back
