Engine runs like crap........

[ACME A12]

My new one is even bigger. I have everything to put it together except bottom end. I was going to order stroker kit but economy put me on a tight budget. Everything I have is good to go with that cam.......except..........If I figured my compression correctly it is only 7.75......ouch......flat top pistons are down in the hole .100, 906 heads 76cc 4.280 bore X 3.380 Stroke........:brickwall: :brickwall: :brickwall: So now I'm thinking I should get a smaller cam and run it till my budget changes.......

No Coronas last night. Does this quote not sound like a new engine?

Okay, perhaps I was looking at this from the wrong perspective...maybe you should have had a few Coronas...

I can see where the confusion comes in...suggest you put Hoosier on "Double Top Secret B5 Probation" until he starts dividing different subjects into different paragraphs...

:jester:

I think you have the right idea, throw a small cam in and enjoy it, but #8 still concerns me to have the wet and dry test like that. Then put the other engine in later :jester:

You're right about #8 - maybe that one tagged the piston just a touch harder than the rest and the valve is slightly bent...easy enough to check that out... Maybe the PO lined up the compression rings on that cylinder... Something is amiss...

I'll keep you guys posted. I'm pretty frustrated with the whole situation right now. I will work it out.

I ran a sixpack cam in mine runs real good.It has a good responce time.
Just a 383 .040 over Eagel rod and stock crank ,and Keith Black pistons.With a 4 speed and 489 355 sure grip it will get your attention. :cheers:

Do you know your compression ratio or piston part#s?

 

[toms69rr]

151- 153 per cylinder I will have to look for part # on cam
It is a mopar performance cam

Came home tonight, put the car up on stands, pulled the driveshaft, shifter, tranny cross member, etc.....ready to pull engine and tranny in the morning. Get it on the engine stand for some closer inspection..........

That may be a tough one to fly under the radar.......

Couple more pictures..........

I see the cam gear mark, is the crank mark above the keyway I cant see it? I havent done a wedge in years but alot of engines the timing mark and keyway are different I think you may be way off. That would be the cause of the piston and valves. Got a better pic of the crank gear?

 

[toms69rr]

Yeah your keyway should be at 2:00
Dot to dot puts the keyway at 2:00

 

[69hemibeep]

Your out in the garage pulling the engine when you should be reading this :toetap:

 

[toms69rr]

Here is A pic of mine

 

[toms69rr]

My crank gear has a slot at 10:00 and 2:00

 

[Big John]

If you go to page 9-55 in the Factory Service Manual, there's a good shot of how the gears should align.

What is a mystery to me is if these gears are off that much, how does the car run at all???

 

[toms69rr]

do you think he might have bent som valves?

 

[69hemibeep]

do you think he might have bent som valves?

He may have avoided that with the low compression, but they were touching!

 

[Hoosier Bird]

I'll run back out and get a quick picture for you. Here is some more while you wait.
