The Best V8 Stories One Small Block at Time
Its fair to say the LS is a better platform - its more advanced, its more current; I'll agree is easier to make power on the LS engines (they love bolts ons plus there's way more potential for big cubes). The cylinder head design is far superior, the ignition systems are better and more reliable, and is not not the case that the LS1 PCM is a better tuning base? What else - its a 6-bolt, steel sleeved aluminum block - lighter, better heat disapation, etc, etc.
Having said this, what do you want? Do you care what engine is going into this car? (what engine the car originally came with?).
Better stoplight acceleration? LT1
All out build? LS1
cheaper? LT1 (at this point)
dyno queen? LS1
care about traps? LS1
LS1 is miles ahead in performance and ease of tuning and such. But the fact that you are already in an Lt1 makes it much cheaper to stick with it.
Is nobody interested in an LS1 swap vs. LT1 buildup cost analysis? Forget the LSx vs. LTx argument for a minute... If it came with an LSx, build it up. If you have a shitload of money to do the swap from a GenI or GenII SBC, go ahead.
I'd rather spend 3 grand on an existing LT1 than buy a stock LS1 for 3 grand...
