Looking at the LT1 vs. LS1, and knowing how well the LS1 heads flow.

If you were to take a LT1 and LS1, get the heads flowing the exact same, mill the LT1 heads to bring the compression ratio up to the same as the LS1, and give both engines the same cam profile, they would make the same power, right?

I just was thinking about this, and wondering.

Food for thought.

 

Theorhetically...if you were going 150mph...oh wait that was another thread.

Uhm, If you're leaving the LS1 stock, not touching a thing, and raised the specs of the LT1, it would probably bring it near the LS1 hp level, or at least the advertised hp level...however the powerband for the LS1 would still be in the upper RPM's, and the LT1 powerband would still be in the lower RPM's...

 

There are too many differences that can't be "the same"... no siamesed runners, 15deg vs 23deg, etc. Check out the LS1 vs. LT1 HEADS thread on "Advanced Tech". Might answer your question.

 

with different intake runner lengths and different exhausts, the power output between the two would be different. power output depends on too much more besides cylinder head flow and cam profile. Theoritically , it would be possible, but would take a lot of re-engineering if you wanted to make an lt1's power curve exactly match that of an ls1.

 

I was thinking more along the basis of bringing the engine airflow specs up to par with each other, and seeing where they stand. Basically, putting the two heads on par flow wise with each other and taking a closer look at how they would perform.
