When a good cylinder head swap goes bad...

It seems that no matter how low the mileage, the gremlins can creep in. These are some of the pictures of how to turn a six hour swap into an 11 hour headache. But it's done, runs like a bat outta heck and I'm happy and ready for tomorrow's show at the Cape.

The number three right side stud (which runs through the water jacket) with the penetrating oil soaking around it was completely galled to the head. We had to heat it, air impact shock it and use the weight of the car to pull down and break it loose.

I have more pictures of the rope in the cylinders, but those will all be on a separate web page on my site next week.

Re: When a good cylinder gead swap goes bad...

The project looks like it was worth it. Very nice.
We had a stubborn stud several years ago on a 4 motor. Fortunately, it was out of the car. We were able to break the head/head gasket away from the block and spin it out head and all. Pretty awkward, but it worked.
After the head was separated we were able to drive the stud out of it.

Thanks for the compliments.

When we lifted the head off, the stud turned right out of the block.

Shannon,

Ignition was at 1:30PM today. I drove it about 60 miles then took it home to cleanup for tomorrow's show.

The higher compression seems to have the most effect at the low end. I can lug it down to 1,200 RPM in 4th and step it down and it boogies right up to speed without missing a beat. Although from 70 to those nice triples is not slow either now that I think of it.

I will install the new JM Wagner Silicone V/C Gasket next week due to the 24 hr. waiting period for the silicone to set. That will be a follow up posted here also.

Finished product below, ready for the 90 mile drive to the show.

Re: When a good cylinder gead swap goes bad...

Yeah that compression is nice; Although I changed nearly everything about my engine all at once, I've been told that even with the cam and the alloy flywheel, its much stronger on the low end than a stock TR6 (obviously the high-end too).

PS, I'm finally getting my exhaust bungs for the O2 sensors welded in tomorrow morning. Once I get my A/F dialed in, it's time for a dyno tune. After that, I figure a couple years of therapy to get over the ungodly amounts of money I spent for a 15 horsepower increase over stock. /bcforum/images/%%GRAEMLIN_URL%%/crazyeyes.gif

Jeff,

The header is the one that no one likes, except me and Tom. It's a Pacesetter, coated in and out with JetHot Coating. And yes, it is definitely cooler running than a stock manifold (about 15 degrees) and it cools down twice as fast.

Re: When a good cylinder gead swap goes bad...

Shannon,

I have my carbs set in pretty well now, but I never would have got them as close without the A/F meter.

Well, let me rephrase that a bit for the purists. I never would have got them as close (in such a short amount of time,) without the A/F meter.

I just went down to check where a part was that I need to drop off at the powder coater and I had to check my invoice drawer to see if it was back ordered. My policy has always been to never look at that file unless a case such as this arises. The file is getting bigger than my waistline and fast.

New policy goes in affect tomorrow. All invoices stay on my desk until order is in my hands complete. Then file invoice so that I can just open the drawer and shove it in without looking too much.

Looks like you used the Valve cover stud holes to bolt the chains down? Did you actually raise, then lower the car while keeping the chain tight?

Hello Paul,

"1,200 RPM in 4th ",

I'm not sure what that relates to in mph. but guessing at around 27 to 30 mph.

The Triumph chief designer of the late fifties would not be impressed, his test was top gear, ten miles an hour uphill and pull away steadily without a stutter, obviously not a performance engine man.
