This is true but they used a new L/J block with a cast crank . The 283 blocks had the rear breather port and front oil fill port .

You can make a S/J 307 engine out of a 283 block with a S/J 3.25 327 Crank and a set of 307 pistons .

I always liked the larger bore idea more then the stroke to CI one . This is the reason I will not build a 305 for a street / strip set up with its 3.736 bore . But The 305 can be a great street engine and give good MPG .

That Mopar 318 is a good runner . I do think I could build a 318 to out power a Chevy 305 .

I built a 320 cu small block Chev using a 283 SJ crank in
a 327 SJ block bored to 4.125 . I did this for a oval track
class that used a cubic inches to weight rule. I would turn
it to 8,000 RPM most of the time . The block was from a C50
truck .

Yes the walls were thin, the first block did not make it, hit water.
That is why I mentioned the truck block, thicker walls ? or just plain luck ?

I do like this build . but with a 400 block . I have built 406 SB Engines They make lot's of power . But they also run hot with that steam hole set up . I really never liked the 383 builds . So I will try another 400 30-over 406 with a good water pump and large radiator . COOL I Hope

You are right the 400 would have been much easier ,but I built this back in about 1968 , before the 400's were common . I specal ordered the pistons
before boring the block, so it had to work even if I had to sleeve the block.
The weight savings on the car by going to 320 CI from 327 CI was 100 lbs
for oval racing this was a big avantage. Also a steel 39 lb crank and aluminum
rods. Yes it did run hot , but oval racers never look at guages anyway
.LOL

Ok gang. It's been awhile. With everything that was going on taking care of my mom's affairs and making a few needed mods to the Healey, it was June before anything really got rolling on this...
