looking good!! Russ got those rods from me a long time ago i believe lol.. glad you are doing something with them.

[aifilaw]

brand of your rockers?

specs on the cam?

Did you get the lifters as a kit as well from comp, and how much $?

I am halfway through the process of something quite similar, as far as the style of valvetrain and bore/stroke ratio and block.

Nice engine but one question , Comp ratio is only 9.8 with alum heads ? You could have easily gone higher with alum heads no problem don't you think ? Iron 9.8 OK but alum easily higher

[aifilaw]

With that cam and those heads, I would venture a guess that he could have made his static ratio about 11.5:1 and been able to run premium unleaded... perhaps a little less what with the ethanol addition, drop that about a point and you can pull off 87 octane at Sea Level.

That's a nice engine build Ranger....should make lots of torque and descent horsepower. 

The 9.8:1 compression is fine....the Comp hyd roller with it's short 224*@.050 intake duration will trap lots of air in the cylinder at lower engine speeds. That cam is a good match with the 9.8 compression....someone was doing his homework. 

If you were wanting to run a larger cam then the static compression could certainly be increased. It's not all about static compression....the camshaft's intake closing point determines cylinder pressure as much as compression does. Everything needs to be balanced for a strong running combo.

225 head?

[lisiecki1]

It's off a flat 6.....other than that i have no idea

[firefighter3931]

BTW
Can anyone ID the head behind the pistons?

I don't see any combustion chambers on that head so whatever it comes off of will have lots of compression ! 


Is it a diesel head ?

do you have 2 intake rockers next to each other in that picture?   where in montana are you?.     im guess a small tractor head of some sort?        looks like a nice motor. should be alot of fun
     

[375instroke]

I'd venture to say that it's an overhead cam head, and probably a diesel.  See a spark plug?

It should be a fun engine.  Mine is basiclly the same except i am using the xe275 cam with 1.6 rockers.  Mine made 375hp/401tq at the wheels.  In the spring i am going to bring it to the track to see what it will do.

That should run nice.

P.S.-I bought my '71 Superbee from a guy in Great Falls in 1989. Didn't see much of the town though. Flew in at about 9pm and left town about 9:30 headed for home in the car.

[General_01]

Actually, I bought it off of a guy named Richard Carlson. No Mike's in this equation.

[firefighter3931]

Got all the parts now....should be done soon.

Right on ! Ok when is "dyno day"
