Hey Guys

Ive been looking for an ls motor to do a swap into my 2nd gen t/a. I found a 5.3 from an ssr with only 7000 km on it for a decent price. What are these engines worth and are they comparable to an ls1 because i realize an ls1 is a 5.7l. If i was looking to make some good N/A power would it be better to just look for an ls1, ls2...etc

Thanks Mike
