400 to a 426 hemi??

[richard pettys 73]

can a standard 400 big block be made into a 426 hemi???

[WingCharger]

No. The HEMI block is unique, along with everything else.

[Hemidog]

No.
I think you need to read up on hemi's vs wedge engines...

ok thanks...then i guess i will be trying to find a 426 hemi or block....

[ACUDANUT]

Someone made Hemi heads before, to bolt on wedge engines. 383/400/440..I Just can't remember who and if they were any good ??

[mauve66]

stage 6 engineering, i can't find anyone who has them and their website 2 years ago had nothing on it, you can make a 400 into a 426wedge motor though

[Ghoste]

You'd have to get a custom stroked crank to do it though wouldn't you?  Most of the 400 stroker kits start at the 451 cid size I believe.

400 block 440 crank is a 451 stroker can get a lot of power for a lot less money.thats what I would do with a 400.

[richard pettys 73]

THAT SOUNDS LIKE A GREAT IDEA... I MEAN WHO IS REALLY GONNA KNOW WHATS UNDER THE HOOD RIGHT???

i was just thinking you could over bore it to get to that point, not really the stroker thought, what would it be at .20 over??  .30 over?  .40 over??,,, etc

[Ghoste]

400 already has a larger bore than a 426, the crank has a much shorter throw.  So it would take a little less than 4.5 just doing a quickie on the math-which is about a .250 overbore.
Since boring would actually be sizes like .030 or .040, to go a 1/4 inch oversize is a little too much.
