This is my 1st post here after lurking for awhile, lots of good stuff. I have a 440 block that a local machine shop is building into a 512 stroker. For kits, looking at 440 source, eagle and muscle motors or piecing together my own. My machine shop has built a few 440 source and doesn't seem thrilled about them, would like to use Eagle but I've heard mixed reviews. Street only car, maybe a few passes for kicks but not a definite, needs to run on 91 octane as 93 is not always available in my area. Going with aluminum heads, lunati hydraulic roller and want a compression ratio close to 10.5:1.

Muscle motors seems to use Eagle or K1 cranks, Icon forged pistons, and not sure on rods.

What kit would you guys buy and why? Any proven engine combos on here I can read about?
