Lucky Me, Now What
In my opinion :
- If you *insist* on going with a big block , I'd suggest the 383 ( or even a 400 ) . It's a big block with small block behaviours ; they're easier to drop-in than a 413/426/440 , et seq. ; power brakes can even be utilised .
Make it look factory stock ( like that FJ6 Scamp with its 383 Super Commando ! ) .
- I'm personally split when it comes to small blocks . The classic 340 is my favourite . There's just some-thing about saying "three-forty" when asked as to what engine you've got .
Then on the flip-side is the new(er) , Magnum-series 360 . Roller Cam and lifters ( no ZDDP additives after break-in ! ), superior heads , better distributor design , etc.
In the end it's up to you 100% .
