I have a question. I want a 00 trans am but i dont want the LS1 i want a LS7.so i was wondering if a LS7 would fit,bolt up,wire up with everything just like the LS1 does.if not how would i go about doing so.sorry for the question but im a noob when it comes to this stuff.

 

Buy a gutted out T/A and LS7 crate motor seperately, combine the 2 and Voila! Instant gratification!

 

with $$$$ anything is possible

 

Go for the LSX

 

Moving to Conversions & Hybrids...

 

LS7 = dry sump...

LS1 = wet sump.


Gonna be tons of fitment issues....


You can make the same power easily with a wet sump motor...

 

Is the LS3 the dry sump like the LS7? I know it's a hybrid motor itself straight from GM.

I also +1 for the new GM LSX Block that has high CID headroom.

What about LS7 heads and intake on an LSX block?

 

The LS3 is a wet sump. Just a few more CI's than the LS2.. It does have variable valve timing, so there are some issues there.. At this point, you'd need a complete takeout to make one work I think..


You can get at least 427ci out of the 6L iron blocks. Mine will be at 408 with a .030" overbore.

 

The LS7 is going to be the 58 tooth reluctor as well, so the stock 2000 computer aint gonna work. You will need all new wiring and a computer that will work with the 58 tooth reluctor, or pull out the crankshaft and change the ring to a 24 tooth.

 

what kind of tranny should i use for an Ls7 crate engine.

 

I'd go with either an auto or a manual.



Kidding. Either a 6 or a built 4L60/65/80E
We can't help you with that decision.

 

I have an LS1 with a Z06 cam in my sandrail. The PCM has been moded by Street and Performance to remove all the street and emission bullcrap.

If I went with an LS7 motor and a 24 tooth reluctor, could I still use my same PCM? What about the wiring?

 

the ls1/6 and the ls2/7 do not share the same sensor locations or all the connectors. the coil and injector connectors are different, the map sensor location changed, the knock sensor wiring and location change, cam sensor location, and possibly the maf and iat sensor arent the same

 

Thanks for the info. Scrap that idea for the time being. I'd probably just hurt myself with that much motor in a 1600 pound sandrail.
