i am about 60% done with swapping out the cam in a 351c 2v.

i have taken off the water pump, timing chain cover, intake, push rods, and timing chain, plus whatever else was in the way.

but as always i have a question or two.


what is the torque specs for the water pump and intake?

how in heck do i get the crank timing chain sprocket off? (any tips?)

and how do i adjust the valves after i am done?
they are stock rockers.


what is the sensor behind the intake? is it the temp sender?

does a cleveland distributor use a distributor to cap adapter?
its the collar that goes between the dist and the cap.

when i pulled the intake off there was a lifter valley pan type gasket.
but my replacement gaskets are the two intake gaskets with the cork strip.
can the pan type gasket be ommitted?

i probably have more questions. but this is all that i can think of right now.

What type of intake?
I take a shot at 1 ro 2 of the questions.
The rocker arms if stock will be postive stop.
You should use a gear puller to get the crank sprocket off.
That will be your oil psi "dummy light " senser at the back of the motor.

its a torker intake.

i pulled the cam and the first bearing is torn up.

so i am going to yank the motor and see if i can reuse the crank and rods, and see if the block has already been punched out.

i have a 4v standard bore block that i might swap the parts into. what a pita.

anyone know the CC size on a set of 73 cleveland 2v heads?

dunno if they are open chamber or closed. so can i check without pulling them?

i guess i will have to pull them anyways...

all 2v are open chamber in north america
aussies got 2v close chamber, maybe Kiwis as well

Blocks are the same whether 2v or 4v, 4v's are more likely to have 4 bolt mains. They are not required and the aftermarket ones are better if you absolutely have to have them. As mentioned, all 2v heads are open chamber / non quench. Running a torker on 2v heads isn't the best combo. There are better 2v manifolds out there. I have a single plane street dominator on my 2v headed motor. Works pretty good but gives up some low end. Use your best block and don't worry about what head came on it as it doesn't matter. Look here for more answers.

I thought they where 68cc's. Flat tops work good with the 2v heads, yeilds around 9.3~9.5:1 CR I think.

i thought the 71 and under heads were closed chamber?


the cam bearing was torn up when i pulled the cam.

so i am yanking the sucker and hopefully the crank and rods are still good.


(i take it that i can not attach photo's on corral.)

 

[michael85]

well by attach photos do you mean will this site let you upload them? I would guess no.
you can link to them once you have them hosted somewhere
why would this site pay to host your images?
use your own webspace provided by your ISP and link to the image with [ img ] tags same as every other forum online

In 70 the Boss 351 was intro'd with 4V closed chamber heads machned for adjustable valve train, a solid cam and 4 bolt mains. It was continued in 72 with the 4v open chamber head and hyd cam and was renamed 351HO.

The 351C CJ was first seen in 71 ands came with 4 bolt mains and 4V closed chamber heads. It later became the 351C 4V in 72 with the open chamber heads.

The 351C 4V was made from 70-74 and used closed chamber heads until the 72 model year and then switched to open til 74.

I thought 71 was the first BOSS 351

regardless, the poster was asking about 2V heads which you did not mention at all in your post

70 was the first year for the Boss 351. My info is for both the 4V and 2V heads. The omission of the specific 2V specs is because they don't come in a closed chamber form, open chamber only. They have 76.9 - 79.9cc chambers.
