thank you guys for all your help..

i just did a 5dollar upgrade to my truck but it looks 100 times better. i will pst pictures soon we had alot of snow drop on us last night..

hooker is a good brand but how much do they differ from like flow tech brand..?

OK. i did a new intake Edelbrook and it the aftermarket one very nice. my question is there are two hoses that are 5/8 id guess. and they where going into the intake what do thise go to on the intake and there is also a vacum line going from a tee in the intake and then out again. ive lef it disconnected and ran it. i ran just fine but it revs a little higher..?

also did new plugs and wires, and new oil...

my new question is..

what tranny do i have withmy 454 engine...? its all stock so im wondering what this truck came with...

i was goin to do the tranny fluids also but they asked me if i had the 400 or the 700r4 tranny..?

any guess...?

Don't leave a vacuum line loose.  If it idles higher that means you've created a vacuum leak.  Fix it.

Looks at the pics on this page for radiator/heater hose routing (and also for inspiration ): http://forum.73-87chevytrucks.com/smforum/index.php?topic=5723.135

Identify your trans by the shape of the pan:

It's probably a TH400 unless someone has swapped in something else.

thank you eventhorizon66. one more question. what the differance intransmissions..?
im sure its the longer and shorter gear ratio. if i want to towe cars with a car dolly but some time step on the gas and haul as. what tranny do i want. i wount be towing cars for long distance. every now and then in town.
and could you posible tell me best to worst trannys fromthe list you should me..?

The TH400 is a heavy duty 3 speed (ratios: 2.48, 1.48, 1.00).  If you want strength and gas mileage is not terribly important, this is the one for you.  It has no torque converter lockup.

There is also an electronic overdrive version of the TH400 called the 4L80E.  It is still in use today in 3/4 and 1 ton GM trucks.  In order to use this one you'll need an aftermarket trans controller or switch to full manual valve body (must always shift the trans yourself).

The TH700R4 is a lighter duty 4 speed (ratios: 3.06, 1.63, 1.00, 0.70).  It offers improved gas mileage through overdrive and lockup torque converter.  In stock form it is not a wise choice behind any big block, but it can be beefed up to live behind mild big blocks.

If the truck is just for towing/cruising/goofing off around town, the TH400 is the one you want.
