Just wondering?? I have a pretty much stock L03 TBI and would like to know what's involved in a LT1 swap? I have a parts car, with no wireing harness or tran.????????
Thanks

To the best of my Knowledge of the LT1 and L98 you would need a complete Longblock LT1 with accesories. The fuel system should be ok. You will need to change the radiator it think because the LT1 has reverse cooling. Ofcourse you will also have to do a complete ECM and wire harness swap. That should be about it, the blocks should mount in the same and the Transmission bell housing should be the same. If not you might have to get and adaptor. Its a lot of work, might be cheaper just to rebuild your L98 or get a 350 block for your current set up and go from there.

The stock style radiator (85-92) works great, actually for this and doesn't need changed.

The line which in an f-body that goes from the H2O pump to the lower DS tank can be capped (it is in a vette) the lower hose is tricky, but I believe my friend used an 80-88 Olds 307 g-body hose; the upper, a trimmed 305 80-88 g-body hose. The heater return on the passenger side tank is used.

If going w/ a 4L60-E, get the 4th gen tranny lines; they have flex at the front, making things a tiny bit easier.

 

what exactly do i need fro a 88 tpi swap out to a lt1 which will be bolted to a 700r4

 

Reading the swap sticky on this subject might help, actually it will help a lot which is why it's a sticky in the first place
