Aluminum 427 Small Block Gen I

[V8bug]

In my mind when you say streetable (reliable) and aluminium block there is only one solution, GM genIII or genIV (ls1/ls2) period.

If you are actual insane enough to shell out $3000+ for a chunk of metal (more $ than I have in my entire drivetrain) I would wait for the GM LSX block coming out this march, it only cost $2500. The specs on this block are scary, 511 ci possibility, 40lbs boost no problem, easily make 1500hp all day. Thats what I would buy.
