i love my opti and plan to keep it as long as i have the car ... i think SBC heads are okay and intakes aswell ... so i guess it is the block that makes the motor an LT1

but what makes it cooler than another "block" or "platform" is the OPTISPARK.

It's interesting with the LS1 crowd because most their all out fastest cars have nothing from the factory engine albeit the cars running ERL blocks. Most are LSX/Warhawk/RHS block, Kurt Urban front mount distributors, after market heads, after market engine management, sheet metal/single plane or FAST Intakes. But then you look at modular Mustangs or the 2JZ and production cast block, production cast cylinder heads are running bottom 6s faster than the LS1 stuff. To me if it has an original block it's an LT1, but when Rick had his Formula people with LS1s would question it because it had SBC Heads and intake.
