BBC 427 or LSX LS7....
Having a hard time deciding on a engine for my car which is a 69 camaro. Im bascially deciding between a LSX LS7 crate or building a all aluminum 427 big block. Now I have all of the parts for the 427 Big block minus the 4 thousand dollar aluminum block but all of the parts are brand spanking new. Which makes me lean a little more toward the big block. Im looking for a good street/strip high fun factor motor. Any oppinions?

An all aluminum BB would wax the floor against an LSX

11-14-2007 #5depends on what kind of floor you're waxing.
The big advantage to the ls7 would be that you could, at least theoretically, get the CG down low thanks to the dry sump. that plus sweet oil control and a crazy redline, plus a little less poundage, makes it a better choice for the track/handling.
For the street...an all aluminum 427bb will be a torque monster. Torque is way more fun on the street. You've already got everything but the block.....I say your decision's pretty clear, even though I love lsx's to death.
edit: researched engine weights a little bit...from what I read, an all aluminum 427 should weigh around 585 lbs, a traditional small block weighs around 575 lbs, and an ls7 is 458 lbs. So there is certainly an advantage to the ls. If that advantage is great enough to warrant selling everything you've got for the BB and starting from scratch is up to you.
11-14-2007 #6go with the BBC. is it going to be EFI'd or Carb? either way, it will be way fun on the street, and plenty of fun at the strip.
