LT1 question

RE: LT1 question
Except for cylinder spacing, they are totally different engines. The Lt1 is based on the chevy small block except for reverse cooling. The LS1 is a totaly new design, has a six bolt cross bolted bottom end, while the LT1 has either two or four bolt mains. Powerwise, the stock LS1 is rated higher than the LT1, when the engines are modified all bets are off, as either can be made to produce over 700 HP without power adders.
