Default Re: early and late LT5 ?

You are starting with 30 HP more with the 93-95....also if you are looking at a 90 model they may not have valve seals on the exhaust...so they naturally smoke alittle. Interms of reliability, they are about the same. But with headers and a tune you should be able to get some decent power out of the later model, they have slightly larger intake ports in the IHs as stock.
