Virtually no difference between the blocks. Some say the pistion skirts of the 302 are 0.019" longer than the 289, others say this difference does not exist. As far as I know this is the only rumored difference between the early blocks.
There are Mexican blocks that are desired for due to better metalurgy.

i went from a manual 3 speed to a t-5, the swap is pretty easy and its the best decision i have made so far....love the overdrive and the 5 gears is so much better than 3 crappy ones lol

i totally agree, great for road courses but not very good for drag races, a boss 429 or 427 or any big block for that matter is going to run train on a 289 all day, just a matter of more power and displacement...the 289 would have to be build to high heaven to keep up...but on a road course...the build 289 will run circles around the big blocks if placed in the correct car
Yeah im going to have to go with new bell housing, cross member, clutch fork, fly wheel, cable and pedal linkage, and drive shaft.

local performance guy did it, when intstalling the motor, he installed the trani and rear end...i gave him free rain on what he wanted to do, so thats what he picked, im not sure the brands, but i can look into it for you

yeah, he just rebuilt the 8 inch with new internals...i am not making the h.p. to break the 8 that i am aware of, even though i havent dyno'ed the car....but i havent had any problems for 2 years now
Update
Fouling plugs, not sure but on the two idle screws do they go in(tighten) to richen or out? Went over all of the other adjustents on carb multiple times and the only thing im not sure of is the idle screws. I started with 2 turns out on both.

im swapping over to a eddy carb\intake soon. does the airgap take away from the bottom end at all?
Very slight loss and only at minimum RPM ranges like idle to 1500. From there on up the improvemnt is huge and the improvement overall VASTLY outweighs any loss. I don't want to start a religous war but Holleys make more power than Edelbrocks

I am going to recommend a holley or demon carb as well, they will make more power. Now for the intake you cannot beat the weiand Xcelerator, it is hands down the best all around intake for the 289-302. Single planes will make more power, and the Xcelerator is not so extreme that it will hurt low end. It almost doesn't drop anything down low but adds so much more throughout the whole power band especially up top. RPM Airgap is good, but the Xcelerator is a better intake, and will give you a better kick in the pants when you put your foot down. Couple that with some roller rockers, exhaust, and a cam you should feel a good difference will give your 93 a run for its money.

I just recommended the Edel for a a daily. It seems to work better than a Holley on a daily basis (I swapped between the 2). Hands down a Demon with an Air-Gap. Do the cam too. Look into the Isky cams, they really do well in a 289.
Update
Well i have not posted in a while, i finally got the motor running better after the carb rebuild and all of the plugs are great except for number 5 (front driver side) compression test was 122 while the other 7 where between 135 and 150. I really think it is not ring related but more of a valve problem due to a slight rattle/ticking coming from that area of the valve cover. Going to pull the cover and take a look see but what should i look for and check other than anything really loose or broken.
