what year chevy  it may not be much considering its only a 4.3 liter.  are you running heads and cam   what size cam?  Ported heads?   what type bolt on?  and what kind of car is it.  Are you looking at high or low end torque?   You may want to get a dyno pull

I have an '03 GMC Sierra.  It has a posi-lock with 3:73 gears.  5.3 liter (327 cui) from the factory. It is a 6 lug, though.

good carb  probly an 800cfm  the two screws in the front / bottem of the carb with springs. work slowly and at idial speed in 1/4 turns or 1/2 turns or one full turn.\n\nturn one screew in (tight) a 1/4 turn listen to the motor go another 1/4 turn lisen for a change do not ever rev the motor....wait be patient.... go another 1/4 never loose track of your starting point  whitch is 3/4 turn now\n\nwhen you hear a change in idial losen it a 1/4 wait some more\n\nnow do the other screew the same. I\n\nf the factory lock glue is still on the screews dont touch them\n\nand this will not save you gas

440 is a big block and may require beefing the suspension.. \n360 would probably be a better fit. 440 would defintely give more horsepower though.

A standard 22-250 is pretty fast as is.  I would just go with the fastest factory load you can find.

one the reason they put 1500 on the chevy is because that tells the horse power... and i think you have to put torque in it

Hard to say without knowing a little more, but assuming the cam timing, ignition timing, carb, plug wires and basic assembly were all done correctly, and everything is working as designed, I would say you are probably around 320-350 H/P\n\nNow someone on this site said they HATE when people guess at answers, but on THIS one, that's about all we can do

First of all if we're talking the stress effects of a 5.0 block I would be looking at torque instead of horsepower.... and if it was me, I wouldn't take any chances! I would put at least one block limiter, also called strut: http://www.jegs.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10002&storeId=10001&categoryId=19507&parentCategoryId=10071&langId=-1  on the engine before 450 ft-lb (about 400hp-500hp).\n\nPS- this is a part classified under chassis

no, but it shouldnt be too hard all you should need is motor mounts, tranny mounts, possibly a fabricated driveshaft and the rest is wiring, but if i were going through that trouble, i'd use 4.3l chevy and a th350 trans

If you get a kit then it will tell you whether or not you need to do anything other than bolt on the kit. Here's one site to look at...\n\nOne other thing... You can NEVER have enough HORSEPOWER!!

Scrap both ideas and get a cam, port the heads, and carburate it.  You'll see more results than fuel injection for a very reasonable price, a pre GenIII small block like yours is cheap to build up!

The local ACE hardware stores here in Atlanta carry a wide selection.  I asked for a 5 mm stainless hex head bolt, they asked if I wanted a 20mm long or 40mm.  I have not had the same luck with either Home Depot or Lowes, although Lowes does have some specialty hardware.

Try Global Spec. It's free and allows you to put in your desired torque and rpm, then shows you matching products. Keep in mind they will spam the email account you register with mercilessly.

since pulley size vs. rpm is linear, you can just use a simple relation. 2.5/3450 = ?/4000
