Andr� > Andre > Check this thread at Chevelle Tech, http://www.chevelles.com/forum/ Forum9/HTML/009775.html There is a poster BTN dzauto who has a wealth of info on the 400. He is running 3 or 4 in different cars, one of whic h is a 421. If you email him directly, he may be able to help you avoid some pitfalls. Or do a search on his user name - lots of info there. Personnally I'm an idiot with motor stuff, but tho se "in-the-know" at TC respect his input. > rick > ---------- "=?iso-8859-1?Q?[EMAIL PROTECTED]? =" <[EMAIL PROTECTED]> writes: > > From: "=?iso-8859-1?Q?[EMAIL PROTECTED]?=" <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] > Subject: =?iso-8859-1?Q?Re:_[Chevelle-List]_Small_Block?= > Date: Thu, 11 Jul 2002 10:41:31 +0200 > > Thank you all > > by switching the rods 180deg. what do you mean ? > How does the piston come higer up in the bore doing this. > > What I'm thinking about building (over an extended period of time > because of cost) is 3,75" X 4,155" with 6" rods or if possible 3,875" > or 4" stroke. that would be 406, 421 or 434 cid = BB torque > > Filling the block halfway with block filler and put on milodon main ca ps > > I have a friend racing with two 406's and my other friend have a 400 > cid with a small blower in his street driven 57 Stepside, they are bot h > happy so I think I will give it a try. > > Thanks > > Andr� > > > > > Also for higher compression with a 400 using 350 rods you can turn t he > 350 > > small block rods 180 deg.
