ok now i get what you mean, 7000 rpms seems alot for a 4.8. ill have to wait and see what this little motor will put out, and if it blows up...then its time for a big block! =)

haha gotcha! im use to saying BB chevys, im 17 so i dont know much about the LS motors, ill learn though!

if i ever need a boat anchor i know what to get.. ill stick with the LS motors now, thanks!

I like the idea of smoking someone with a small displacement engine like a boosted 4.8.:) Reminds me of my old 3.0 2jzgte supra that i used to have.

Welcome to the site.

welcome to the site

Welcome to the site. I have a 454 crankshaft cheap if you go that route.

Hey Quik, are you old school 7K RPM or against old school - Big Block Chevy...LOL? If it were easy and cheap to always use LS engines, Super Comp dragsters wouldn't have BBC's....
