Lt1? Any good?
Just looking for some input, i'm 17 and i'm looking to get an fbody. With the money i got it'll probably have somewhere between 60-100k on the odometer. Some people have told me some really bad stuff about LT1's and i want to know how good they are...

the stuff i heard was stuff like the block cracks easy in the higher milage range cause of the cast-iron, stuff like that. I didn't think it was that bad i just wanted to make sure.

hell, ive sprayed my opti when de greasing the engine and it toughed it out.
the blocks are actually stronger than LSx aluminum blocks. why do you think the new LSx block is now cast iron.

make well into 1000 hp. but the iron lsx are even stronger than the alloy blocks.
the new LSx is iron because enthusiasts and racers demand a block tht
will handle up to 2000 hp and big block displacement. and with the LSx
line of superior high flow heads, they warrant a bore as large as 4.125
or more. they are iron because they will be running large bores. and to take
advantage of the heads and intakes available now and the ones in development.

for the blocks to crack, or if overheats to a point whre it can cause damage
to the block. the opti is a weak link in the motor design, most all LT1
hardcore racers usually convert to dist. and or convert sbc intakes and heads
for use on the lt1. sure there are racers with hi power motors still
using opti's. but it is a rare condition that a opti will live long with a powerful engine. i have gone thru my share of opti's
word of advise do not purchase opti's from autozone, advance, oreilly.or
even napa. unless they carry a gm part #. or go with the aftermarket accel
or msd units

I had a '93 Z28 and a '97 Ws6. While the LSx is a better platform IMO, the LT1 can make power and be reliable. If you can afford an Ls1 without breaking the bank, go with an Ls1. But if $$$$ is limited... an Lt1 is a great choice. Just shop around for one that hasn't been abused.

I know several guys with LT1 cars and they have higher mileage with very few issues. From what I have learned, they are a very good platform, just starting to age a bit. I will tell you though that all the guys I know want to sell there LT for an LSX....
