LSA-block based engine build I'm a newbie on the forum so I'm posting this as kind of an introduction. I'm building an E-Force supercharged LSA-block based motor for a '66 Chevelle. Here's a link to a blog of my progress to date. If I get any thumbs-up, I'll post updates.

Just a heads up though, the skirts of the pistons may need some clearancing to clear the oil squirters. I used Wiseco pistons and that's what I had to do. When I moved them away from hitting the pistons, they wouldn't clear the rods. Aluminum is like 2.8 grams per cc, so you can remove some material before affecting the balance of the crank if you do run into the same problem with your CP pistons.

Looks like a nice build.

Bending the oil squirters worked Fortunately the oil squirter tubes are bendable, not brittle. I was able to bend them to clear the pin boss with very little effort. I completely agree about not wanting to touch the pistons!

The LSA I had to notch the skirts in ended up making over 750whp on pump gas and has seen several TX Mile as well as SCCA autocross events over the last two years. Notching the piston hasn't seemed to have had any noticeable effect on the power or integrity of the engine.
