76 military Only 30k No rust Runs but poorly One day...

My machinist told me when he has checked those that are SCAT balanced, they are not as well balanced as he likes. Course maybe he likes doing the work to pay for his machine. Just an FYI, the flywheel for external balance is on the spendy side.

The steel bushing upgrade is complete. I used a reamer to create a snug slip fit for the bushings on the countershaft. This was after annealing the hardened steel bushings by heating them red got with a torch, then letting them cool slowly in a coal bed in my outdoor fireplace. They were trimmed...

I'll take them.

Parts for engine assembly are here. I was waiting for pushrods. I have 0.025 valve height variation so the adjustable HS rockers are nice to allow consistent preload setup. The pushrod length is just right. Some have about 0.010 preload with the adjuster fully backed out which is fine.

To my knowledge the cracks are generally harmless. I'm sure there are exceptions. My thought is not to repair them. Run them or replace them with aftermarket heads. I suspect a repair would not last. Just my guess, not from experience. Others will chime in.

One thought in considering cost. The magnum head adds expense unless you stay with factory rockers. One expert says they are good to .525 lift. I planned to go that way but did not like how much contact angle this produced on the valve stem. Wound up buying Harland Sharp adjustable roller...

I've got the book listing all the ratios. Everyone seems to like the functionality. I'm about to address it's only real weakness putting steel bushings in the aluminum case for the countershaft. The OD from a car is harder to come by and tends to be spendy. I got this cheap and it's in perfect...

Liking it.

Been off the forum for a bit working on my daughter's house so she can sell it. Hot market she had offers above asking before we were done. Just got Harland Sharp roller rockers to solve issues I was having with the stock valve train. I'll be posting on my build thread listed below.

Nice. Thanks. The Magnaflows sound great.

Any chance you could post a new link that works? Was just looking for a full view of your nice ride.

Sounds to me like you have it set up nicely. Great looking car.

At one time I contemplated a big block. I love the low RPM torque. Cramming one in to a tight space did not appeal, so I decided to do a very cost effective "junkyard 360" which upgrades heads, intake carb and cam, leaving the shortblock untouched. I still think that's a good proven pathway. It...

It was available, and the conversion is not difficult.
