L-99 4.3 V8 is rated at 200 hp.let me solve this riddle.
1. get in your car.
2. turn it on
3. get on a long straight road and mash it.
if your head hits the seat you have an lt1. they have 80 more hp and over 100 more fp of torque.
seriously, if its fast, its an lt1. if its slow, its an l99.
That's a 350 ci block.when i blew the first motor i remember worrying about this....there is 327 stamped on the block right below the cylinder head i forget what side i think PASS.
i forget the # for the L99 block
so it ain't too hard to figure out, but the dude that said if you have single exhaust is right for the dead give away if i recall...
Yes indeed it is. I was just agreeing with fatvet's post. L99's have "588" cast on the side of the block.Yes it is.
However, the number 327 is cast into all 5.7 liter LT1's.
It has nothing to do with the displacement.
It is the definitive way to tell an LT1 from an L99.
Fatvet is absolutely correct on this.
