4s 5s and 6s? Wanna bees?
. It's easier to build a big block. But there are much better head and block choices for small blocks, much better packaging under hood, and much faster revving. Not to mention a race 59° block starts around $1800 IIRC...With machining, you can have $3500-4K into it. The base big block as shipped from MP or Indy is $2500, and the machining still needs to be all done or corrected. That's assuming your MP block ever comes in, and when it does, it may not pass the sonic check to be built to where MP said it could go to. Aside from the KB $5000 versions, big block bare blocks are a nightmare, from Indy or MP. Just stating a fact. I know more than a few small blocks under 425" that run way in the 9s N/A. I think that equates to faster than 6s. Plus, they fit easier, handle better, and can be easier to work on. I like 'em all, but saying they are all wannabees is a sign of lack of vision, or knowledge, or experience with both. If you never have, everyone should all drive a 4" arm A body...I've driven 4.15 in arms in B blocks, and they are fun, but not like tha 4" small blocks. I'll have a 4.25" RB (505") customer engine done in a couple months, but my truck and street car will both have 416/418s in them. In both instances, using a small block block means I'm saving over $4000 on mounts, suspension, braking(power booster), headers, transmissions and the associted support hardware. Guess I'm a cheap wannabee..lol.
