Another bingo!  The differences were as simple as that.

another recommendation, and also more suitable when you're on a budget: How to Hot Rod Mopar Small Blocks. Beware to buy the newest edition, it has some 40 extra pages. And the book Chrysler Performance Engines is a must as well. These books together will help a lot in knowing which parts to look out for, even if youre on a budget. The "how to hot rod SB" is one of the books I sell most.

and if they dont have these titles, check on amazon. I bet you can get the books for less then $10 each.

Backing up just a bit to the 428 CJ engine,...there were actually 2, 428 engines. In 1969 the 428 CJ was a big seller,however,if you checked off the box,and ordered the "optional" 3:91 or 4:30 gear ratio with Traction-loc diff.,you got the SCJ 428,and in Feb,you could order the "Drag-Pac" option for $147 and get the SCJ 428. This stood for Super Cobra Jet!. I had a Complete SCJ,4 spd w/9" rear with the 4:30 trac-loc in my 57 Ford that i once owned. The SCJ consisted of External oil cooler,w/ 427 "Lemans"capscrew rods,special crankshaft w/large damper (sort of like a 440-6 bottom end) and they were assembled and balanced by a special team of workers. The hp and torque #s stayed the same however,as the intake,heads etc. stayed the same!. The difference between the 360 and 340 also were many,although similar,the 340 fits in the same catagory as the 426 Hemi.That being,just like the 426,..there was never a low performance 340,only a detuned 340 in 72. And if the 426 would have been made in 72',...it,too would have been detuned.. And to back it up even further,..the 302 chev engine,was just a 283 crank in a 327 block,nothing spectacular there!. In fact,..if they would have given the 327 the same parts as the 302,they would have had more hp,because they would have had close to 10% more cubic inches,.......Just my thoughts on those subjects.

Glen, the 302 was built to Trans-Am specs - nothing larger than 305 c.i.d.  So it's not about what they cold have done, it's about what they did do to run in that class.  The '70 Challenger TA and 'Cuda AAR cars were sold to the public with 340s, but on the track they ran 305s.  The Chevy Z-28 with a 302 (only car to have that motor) was for the public what was being run on the track.  Could be why a 302 powered Z will draw more bucks today than a TA or AAR, even though there are far more of the formar cars than the latter.

Tater, the LA motor originated in '64 with the introduction of the 273 small block.  That block was bored to 318 c.i.d. in '67, then 340 in '68, and finally 360 in '72.
 
 
I was looking at a '71 Newport in ebay today that was claiming to have a factory 360 in it.  You will notive what  said a few weeks back about the 360.  So, I grabed my trusty Chrysler Corp. Code Book and - viola - I was [color=#ff0000 size=6]WRONG![/color]  The 360 was, indeed, first offered in '71, not '72.
 
See, I correct my mistakes.  hey are few, but I do corect them.

If you are using the trusty book i have. . it's wrong.  The 360 wasn't offered until 1973 in the Newport.  It also had electronic ignition standard then.
 
I know this from another source, dead now, and first hand experience. . .  Special circumstances make me remember this particular topic.

They however,were planning on releasing the 360 in 71' as my 71' "J" heads are clearly marked 360 even though it was on a 340 block!. I would love to hear an explanation about that one also!. I do know that the 73' and 74' blocks were highly sought after from the Super Stock crowd as the webbs were very thick compared to later years!

Up here in and around these parts,the '71 360's are sought after.Thick cylinder walls make for .060 overbore without comprimising strength.Add a 4" crank and you have a horny 402 C.I. stroker.Later casting are not as thick.
