Are you needing advice, links, tricks, or all of the above?
If it's advice you want:
If you are not buying an after market harness and all of the oem wiring is intact replace one wire at a time from the component all the way back to the fuse box. Its tedious but, it's a sure fire way to get it right the first time.

Secondly, I'd by a haynes manual or some other wiring diagram. Study it for at least a couple weeks or until you are completely comfortable taking on the task.

Color code your wires and label both the old and new ones with paper tape and a permanent marker so that you know what each one is for.

Last but not least, make sure that the battery is disconnected... ;o)

SOURCE: Will a 700r4 fit into a 87 el camino without

It depends on what the 700r4 came out of. Different vehicles had different length tail shafts. The best thing to do is to measure the length of the two transmissions. You should be able to get a driveshaft shortened for around $150 if you need to do it. Also don't forget to get the vacuum-electric switch and harness for the trans, on the firewall by the heater box.
This will really make a difference in your mileage so give it some serious thought. I replaced a Turbo350 with one and my weekly gas bill went from $100 to about $65-$70. Hope this helps.

SOURCE: 86 4.3 litre V6 chevy el camino bogging down, stalling out

most likely a weak fuel pump or a clogged filter. Check fuel pressure with a gauge or as its bogging down spray brake cleaner in the Throttle Body. If this allows it to increase RPM then its the pump or filter.

SOURCE: my 1985 chevy 305 gets 4mi to the gallon

Check your ignition timing at 3500 rpm you should have about 40 degrees of advance If not, something is sticking in the distributor, either the vacuum or mechanical advance. This will cause a big reduction in fuel economy. Also, check your tire pressure. The cfm on a rochester is really not important. The primary bores are so small and they are the only thing allowing the mixture in most of the time.

Smog pump barely adjustable for 87 chevy el camino 305

get a smaller belt so about 1/2" check that the belt section is correct. the outer edge of the belt should be just proud of the pulley flange edge and not down in the groove.

1985 Chevy El Camino 305ci. Turned over good but wouldn't fire. Replaced contrrol module and it started fine for about 2 months, then did the same thing. Replaced dist cap, rotor & coil. Start

Had an 84 silverado 305 that did the same thing. Try giving it a full tune up. Plugs, wires... Mine turned out to be fouled plugs. I didn't find that out till after i tore it down & put a timing set in it. Wasn't getting good enough spark.

1982 el camino 305 4 brl has just developed backfiring @ carb , ran great after tune up but still had backfire @high speed . It now backfires @ low speed. Could it be timing belt? \ 131,000 miles w/ 400...

the timing maybe off but it could be a miss adjusted carb. there is no timing belt it is a chau=in and that is most likely not the problem. timing is corrected at the distubtor. but i would check the carb it may be dupming to much fuel
