396 BBC build options
What sort of options do you have on a 396 to make more cubes (power)? I don't find much info on this. One post I read said to not overbore a bunch as cylinder walls get thin quickly. I see very few stroker pieces for these. I know most will say find a 454 & go on, but I already have this & running it now. Any ideas? Thanks, Dave

If its a GOOD runner?
Think about a Power ADDER?Cause No matter what you do to make More Cubes,you wont Gain as much as you will with a Power adder?
Small Supercharger would be My OPTION?But,thats Just ME.......

Them 396's are dinosaurs BUT they are good.
I had one in a nova a owed a while back, it would scream and lasted a long time before a (stock) rod finally gave out.
I ran 11 to 1's forged pistons, small 108cc closed chamber peanut port heads, 305 magnum cam, team G, 750 holley, Turbo 400, 411 gears - ran 7.40's 1/8 shifting @ 5500rpm.
I also had a small adjustable Nitrous plate on it which made it really come alive, a 125 pill shaved off about four tenths spraying just off the line.
Now if I had to do it all over again I would up the compression to around 13 to 1, slap on some open chamber heads, a faily large roller cam, 1050 dominator, powerglide, 513 gears.
Should be a 6 second car easily.

It depends on the cating. There were some 396 blocks that were capable of going to 4.25 bore to make a 427...I have a friend that went this rout...but you need to make sure you have the thick casting first...sonic checking it is the only right way but a backyard way is pulling a freeze plug and looking in there...I read it on here something about whether or not a pencil would go between the cylinders I think it was.
