Yep, you got to love a BIG BLOCK!

There nothing like driving a big block car.

Re: Working on the 74.....
 

Big Block... Shmig Block....
Only one cam!
You could get a big block in a dump truck or a school bus!
😋

Re: Working on the 74.....
 

I love Dumptrucks with all that big block torque!
Why do you think I like big diesels.
With three to four times the torque of your ZR-1.

When did you get home?

Looks like a very nice project. Assembly is such rewarding work.

Re: Working on the 74.....
 

Nothing like the torque of a BBC...especially with over 500+ CI or power adders ..
They respond immediately
My 12 bolt got destroyed twice :(

Re: Working on the 74.....
 

Picked up the engine today and had a good conversation with one of the machine shop owners who performed mostly all of the work on my engine....... I am extremely happy with their work......here is the breakdown for those who are interested......Crank spect out fine and was polished.....original cam bearing were fine....but we're replaced.....Main and Rod bearings were also replaced and new nuts were used on the Rods.....Oil clearances on the Mains are .0025 on the Rods are .002 Cylinders checked out fine and the original pistons were used with new rings.....Piston to wall clearance is .0025. Cylinders were honed on a boring machine with a 280 grit stones.....Quench measured out to be .060 with a .039 head gasket.....Thurst bearing specs are .003-.009 thurst bearing was set @.006 Cam button uses a .040 washer and Cam clearance is @.010- .015 Cam sprocket should have been the 9- key as opposed to the 3- key I have.....Cam was to be set @106.... but was set @107 and will be @106 with chain stretch...
Closest point is @10* BTDC that is about it....not only excited.....but a big learning experience for me.....[emoji16][emoji16][emoji106]

Try to get 0 play on the cam
Roller cams screw in n out of their bores: distributor gear wear is your 1st hint n choose the right distributor gear for cast or billet cams. Cam degreed with lifter or with head n on spring retainer ?
Cam C/L ? Automatic or Stick ? no bushing on crank:I assume automatic
