LS7 Engine bought, but internals maybe a stroker!
Hi,
a couple of days ago bought an LS7 off of a Camaro. Thinking that it was an original. I got the full engine, but no alt., comp., water or power pumps, for $4,500. I live in Kuwait by the way. We open up the engine and the picture below show the internals.
heads seem to be correct GM12578449, some of the valves had caps, but the springs were replaced with double springs for the cam (LS7-GY21). The block is 7.0L, but the rest are not correct for an LS7!
so, I'm returning the engine today, but the guy is asking to reduce the price to $3,300!
is it worth it, I'm guessing not!!

- Don't know if it's a good engine, bought it from the scrap yard, but we opened it up and took it to the machine shop, it looks clean except for the cam which seems to be worn out.
- Block has stock sleeves.
- not sure about the crank.

I imagine getting an LS7 in Kuwait is not exactly an easy thing to do.
So, in my opinion, if you have access to a competent machine shop, work with the seller to give you a deeper discount and keep that engine.
The only valves that should have caps are the intake, as they're titanium.
Find a new cam that will work for your goals.
You should be able to tell pretty easily if the crank is stock or not.
So, if it's a 427 or a 454, or a 441, does it really make a difference? The idea is to install a really nice updated engine in your classic muscle car, right?
Best of success with your project!

Also, I'm not sure how to distinguish between titanium or steel valves. Guessing I would replace all to SS valves maybe.

it would definitely won't matter to me if it's a 454 or 441, but I was worried about the quality and whether this setup would work with a stock cam and heads.

The stock head castings and cam will work with a stroker bottom end.
Not knowing what your power goals are and what it costs to get the work done over there it is hard to give you advice on it.
You really need to find a local performance shop and get some advice from them.
