Default BluePrint Engines LT1

Anyone have experience with these guys?

The 355ci spline drive long block is looking like the best option at this point. Wondering if anyone has used them.

I installed a Blueprint 383 long block in my friends '91 corvette. We had to swap oil pans, so we saw the bottom end and it all looked good to us. I know his isn't an LT1 but the build was quality work. Steve's car has dozens of 1/8th mile drag passes on it and he beats it like a rented mule. No issues in 4 years of hard use.

BluePrint has great reputation and that's a great price. To bad you can't get it with a bigger cam but that most likely wouldn't be stock computer friendly.
Wish BP had something for the '95-'97 car's.
I say go for it.

Remember the Hot Cam needs better valve spring than the LT1.
