Re: 396 bb 1975 lugna s-3
have you given any thought to a 400 with a slight bore job, cubes are there and the weight loss will be a blessing. I know some folks are not to happy with them but I was going to put one in a 67 camaro but going thru the split I donated it forward I like big blocks but if your just going with the 396 why not save some weight, by the way nice job up frontlaguna55 wrote:has anyone put a 396 bb in there laguna ,, i dont have my ori. 350 so i am going with 396 ..

If you have the 396, swap it out... You'll love it.

I've read the 400 motor has thinner cylinder walls than a 350 or 305 and can crack with too big a bore. Not sure if it's true maybe someone else can confirm that? Nice job on your car.

Re: 396 bb 1975 lugna s-3
Because of the siamezed cylinders unique to the 400 engine, this is true. I forget if .060 is safe, but .030 is. I believe the story is if you really want to chance it, .060 can work about half the time. My memory is not what it used to be.

My '74 Malibu has a '70 400, which came from a station wagon. I ran it in an Elco for years, then rebuilt it again, @ .040" over now. Only thing is about those, is that they need a good cooling system, HD/AC radiator, and a big fan w/clutch. I have 350 rods in mine, and haven't ever used the stock 5.565" rods. Comp 280 Magnum cams in both rebuilds, with Rhoads lifters, for decent vacuum.
And it does have plenty of power & torque
My engine shop wont bore a 400 to .060" oversize, and I don't blame them

Good deal, that's awesome. Is the ID # still on the deck? I think they configured the 396 in various ways that year from 325 up to 375 HP. Would be fun to find that out.

You will have to use the correct bolt holes in the cross member, for the big block mounts.
