Verdad Gallardo goals are to make 1200 plus all day and not worry about breaking the bottom end/ car weighted 3800 with me in it turbo car, th400 trans,. its a true sreet car has heat full interior. i run pro efi also . i would like to have a easy low eight car and still be a nice street car.
1200whp+ at 3800lbs won’t be reliable on a stock block (or crank). Should be looking at aftermarket blocks with those goals IMO. Also opens up the piston options. No reason to stick with baby cubes at that point either. Really not cost effective to stick with an LS with those goals at all. BBC would be cheaper to build.
I gotcha. Regardless of the big $ rotating assy, at that power level/weight the block is not reliable. Also when you bore/stroke a stock block it weakens it. They tend to crack out between the cylinders. Guess my point is it doesn't make sense to sink tons of cash in a big $ rotating assy on a stock block. You are already around the blocks limit now at 1100ish whp... esp. if you want it reliable.

^ This are terrible boost pistons. It will more than likely lift the ringland at the edge where the valve relief is cut since it is the thinnest spot. I have done it two years in a row.
Now this is what you want for reliability and BIG BOOST. This is a 4.130 bore custom diamond unit for my 402 build.

I take that back... in all fairness my engine was built with 23lbs maximum boost in mind, considering it is a stock block. ..... for 30lbs there are better options for sure, and a stock block isn't one.

LME is a great company but the OP stated he weighs 3800lbs and wants 1200rwhp. I have been down that exact road. I see you have not with a c6 vette. There is a big difference in weight and horsepower.
The shelf wiseco pistons will get the job done no doubt, I did it for 3 seasons. That piston came at a price though of inspecting it every winter. It is not a reliable unit if you want big power to push a heavy car into the 8s.
The piston I posted is specifically designed with no reliefs because even with a super safe tuneup at 14 degrees of timing and 11.3ish AFR it would still get hot on that edge and lift the ring-land in hole #7.
