engine rebuild

[sw]

well after a bit of hesitation i finally pulled the motor out of the boat. now the motor is well and truely stuffed but as i dont really have the spare $$$$ to throw at this one its a bit of a hard decision to make. i will be doing everything i can myself, to save $$$, pretty much machining is the only thing i cant do as i dont have my own mill.

 

this is not gonna be something that happens quickly as i will only be doing stuff when there is spare cash, now when the missus is crack'n the wip to buy/build a house theres not much spare cash around.

 

she's a clevland 302 V8.

anyways a few pics as starters

the last few nights work

 

one very sad motor

one very sad stripped block

worn crank

 

&

 

6 out of 8 pistons with cracked rings.......

 

the cam is heavily pitted, so i guess it will make a good paper weight now.

Uggh. That is rough!

 

You should seriously consider a crate engine and be done with it.

And unless you run her at 5000 rpm or more, go with a 351 Windsor.

mws im not a ford person in any way shape or form.

 

whats some of the differences bewteen windsor and clevland, im sure they can both be set up to run well in this situation.

 

what are the good and bad points for each?

 

bit of a ford noob here

 

 

 

figured out what heads i have - 2v open chamber.

i also managed to pick up a clevo 351 crank and rods real cheap on ebay. i would'nt of normally gone and got these but the price was right!

oh man.. that one does look tired but 302 in general are bomb proof. i don't really see much difference.. dizzy and intake look a tad different but that could have been a marine update or something.. definitely the h2o pump is not the same...

[sw]

thanks for the info thunderbox

 

however theres a few very cluey ford nuts around the office and i have spoken to them about this. they have said that due to the fact im fully rebuilding the motor that there will be no problem using the 351 crank.

 

have also found out that if i use the 302 rods with the 351 crank i can gain a whole bunch more torque for nothing. obviously i will need pistons with offset gudgeon holes. (cant remember the fancy term for this)

 

also, i know this is pretty simplied....., but i have sat the 351 crank in the block already and spun it over by hand, seemed alright....

Err, wait a minute - 302 Cleveland?

I didn't know this existed. The 351 Cleveland was a weird harold engine that Ford homogenized for NASCRAP racing. It had HUGE ports and HUGE valves for high flow at 6000+rpm. Of course, the huge ports also meant horrible flow at less than 6000 rpm (resulting is weak torque and poor fuel economy). Didn't share many, if any, parts with any other Ford so options are few and expensive.

 

The Windsor was the regular small block Ford used for decades. It's been 20 years since I played with Fords, but the engine in those photos looks more like a windsor than a cleveland to me... Are you sure about it's a cleveland? I recall the intake manifold being much wider...

:confused:

Ooops! Research is better than memory any day.

There was a 302 Cleveland - but only in Australia! No wonder I never heard of it.

So disregard everything I said! My experiences are not relevant to your situation.

no worries man, dont sweet it

 

yeh clevo 302 & 351's are sort of common down here.

 

yeh also the point of heads & vavles, you are spot on however thats not the whole story... the heads with the massive exhaust vavles are know as 4v heads. there are also 2v heads which have a much smaller exhaust valve than the 4v. now i have been lead to believe that you can set a motor with 4v heads up and if you do it right it will run alright below high rpm. however as stated above i have 2v heads, so this isnt a problem for me.

surprise surprise

 

at the mo im getting the block & heads dipped & cleaned up. i ve had the 351 crank checked out & the outlook is not good

 

all the conrod journals are 20 thou undersize, as was stated on the ebay ad - in all fairness HOWEVER one of the journals is flogged out below 40 thou.....

 

sounds like a job for the hard chromers...

 

o well least its gonna be pretty shmicky when im done!

 

 

also found out i dont have open chamber heads i have closed chamber! - all that means is more compression
