I'm looking for an engine for my 59 Chevy Apache and wanted peoples opinion on what engine I should put in my truck. Right now I have no motor and will be starting from scratch. I've narrowed it down to a 383 Gen 1 carbed (or Holley Stealth Ram) or a LS3 EFI crate. It looks like it's going to cost about the same for either engine. The 383 would be around 450 HP & 470 # torque. The LS 3 would be 435 Hp & 424# torque. Does the LS 3 have the torque down low like a 383? If I changed the cam in the LS3 what could I expect? Will the LS3 will be more streetable if the power & torque on both motors are equal?

Just curious, but why an ls3? I know I'm boring but a lq4 with a radix blower on top would be the cat's pajamas and would be good for 550rwhp/tq with the supporting mods.

I'm thinking he's wanting a crate motor...

Yes, I'm basically looking for a crate motor that's as complete as possible because I need everything. Right now I just don't have too much free time to build a motor. I have called a couple of vendors and it seems like a motor that has the same parts as the crate will cost a couple of thousand more.

Just curious, but why an ls3? I know I'm boring but a lq4 with a radix blower on top would be the cat's pajamas and would be good for 550rwhp/tq with the supporting mods.

just curious why not an ls3? I had planed on a N/A 418 using a ls3 block is there reason not to?

LS3 would be pretty neat i say go for it
