well i got my motor up on a motor stand
rebuild time

cam went out
well what should i replace
or beef up?

on budget

so what do you guys think i should get
what are some of the best part's / value?


any help or opinions would be greatly appreciated

 

you need to say what you want out of it and how much you want to spend

 

I hope that you have a better plan then just pulling the motor and then thinking/asking "what should I do now?" How many miles are on it? Are you planning to do most of the work? What made your decide to take it out in the first place?..knocking? burning oil? etc. And like ede said, how much do you wanna spend? A little word to the wise that will be agree with some people here but contested by others...I wouldn't put too much time or money into a 305.

i just wanna put enough into it to make it quicker than before
it has around 90k miles on it
im doing all the work other than getting it machined myself
(with some help from people i know that know what they are doing)

it wouldnt even run
like 3 of the lobes were flat on the cam

spending maybe just enough for a cam and what else do you think i should do with it??
as long as i get a lil more off the line power i will be happy

thanx for wanting to help me

 

cam... port the heads a lil while they're off... match the intake to them...

perhaps raise the compression a lil....

when they redo the heads to put new seals and valvesprings on them, you might as well have them put in bigger valves (be sure it fits in the bore if its a 305)

 

there is alot of buildup all over the outside of the block and degreaser doesnt seem to be handling it
would it be safe to use a wire whell brush drill attachment in combination with the degreaser to get it off
its like 1/8" thick and tacky
this motor is dirty

i wanna paint it up and make it look pretty while its up there

 

get a can of either Gunk engine degreser, or walmarts one... i forget the name, in the black can....

the walmart one is cheaper, like 88 cents a can if i remember correctly...

get a stiff NYLON brush... dont use a wire brush... it'll jsut scratch everything


roll it out into the driveway or wherever you;re going..


if you have a pickup truck or trailer, have you and 2 buddys haul it to the local coin op car wash.... otherwise, drag the garden hose out there...


put some duct tape or several layers of masking tape over the exhaust port, distrib hole (pull the distrib out) carb hole, or any other inlet....... then spray it down with Gunk, run the brush over the really bad areas, hose it off, and do it again till its clean...

if you already drained the oil and are going to completely tear it apart and have it bored out or whatever, dont worry about if some water gets in the motor.

if you're going to reuse the shortblock, use some caution... be sure not to drop that crud in there.


carwashes are great because you dont leave a oily mess everywhere.

if you or anyone around you uses well water, do the polite thing and dont wash it where the water/oil will seep into their watertable..

 

oh, and as soon as you finish cleaning it, pull the duct tape off

otherwise, the gunk on the tape will adhear to the parts...

if you're not working on it for a lil while, and when its together, its a good idea to cover the holes.... use masking tape.... good masking tape like scotch, or 3M..... they leave a minimal amount of residue on the parts.

 

If the engine is out, and the cam has been wiped out, you really need to replace the cam bearings. The easiest way is to have a shop do it (unless you have the puller/installer set). Since the block has to go to the shop for bearings, you might as well have them hot tank it clean - they'll probably want to do that to boil out the cam bearings anyway. About $25 and everything is whistle clean - inside and out. That would also be a good time to have them check the bores' wear and mains alignment From there, you should have a good idea what to do next.

 

cost me 40 dollars a few weeks ago to get a block cleaned. it's a good idea and the shop, or my shop, will home the bores and measure everything. cam bearings are 35 to install plus the cost of the bearings, i do my own plus my own freeze and oil plugs, saves me a couple of dollars.

 

Yeah, but that was a big block - it takes more caustic. Plus, you pro'bly go only to those high-end machine shops....

Still, unless you have the faclilities, the money you would spend on Gunk cleaner (or whatever you use), brushes, solvents, the frustration, cleanup of the neighborhood, etcetera, would be better spent at the shop.

 

heh, i should point out that what i was saying is for a engine you're going to reuse..... hence covering the ports and such...


if its just being torn down and sent to a machine shop, they're going to clean it anyway.... just send it to them...
