i HAD to steal these pics from ROP. this is the worst Olds carnage ive seen so far. its a weak 403 "windowed" block to begin with and wasnt built properly.






BTW, i decided against building a BBC. im going back with another Olds 455 for my next build

OUCH! Shocked Being able to remove pistons from the bottom side while STILL attached to the crank - that's about as bad as it gets. Amazing carnage! Clay

GM does something like this in the supercharged Cadillac engine. They use basically a hole located through the bulkheads to supposedly let air / oil mist to move freely through the crankcase when the pistons move up and down to free up h.p. Do you think Oldsmobile was ahead of it's time in trying this idea or they were just trying to save material and / or lighten the block? Curious, Clay.

intresting concept. i would like to think that Oldsmobile had some logic behind that weak design but, looking at that pathetic oil pan rail, im going to have to go with "save material".

Not sure if I am reading this right. Is that the engine in your car 10 sec? That must have been a expensive sounding noise! Or should I be asking is that what is left of it.

as far as i know there is only one design 403 block and they all are windowed. im not 100% positive on that because i have no intention of ever building a 403 so i havent researched it. there are, however, different variations of the 350 (none are windowed). theres the NASCAR block (most desirable), diesel block (also well sought after), and the plain old gas block.

I read years ago that it was done to lighten the block so that a "big" engine wouldn't effect the handling of the car that people had come to expect after driving the smaller V-8's that proceeded them. It is why a 455 Buick engine weighs less than a SBC, it's mostly holes (especially those eight big ones).

Didn't notice that the first time, now I absolutely agree with you - save weight. Clay
