Gotta go watch my grass grow, now.
We melted 2 feet of snow this past week.
I have a 2000 Nightrain tore down waiting for warmer weather to build to make room for a couple shovels and HD golf carts to tune up and I'm not heating the garage.
Besides, I need my free time right now to recover every week from a work week with UAW local 94. I'm too old for that **** but the $$$ and bennies are too good to pass up. Its a killer pace but when CIPP pay is like 145% of a base of $30.00+...well you do the math. Our line has some money hungry people. Rate is 42 units a day for skidsteers. We were done by noon and sat there til 2:30 quitting time surfing the net on our cell phones. Every day. It's insane. k
I'm not pushing woods cams.. I've used a bunch of different brands. Only Woods cam I bought new was the W-5 and I knew I'd be selling / trading it. I do think that bobby miscalculated on the M8 cams. After all, why is there a 222xd -> 22xe.. He's still looking for a good combo IMO.

It will be 79 here today. Was going for a ride but grandchildren showed uo.. Will go tomorrow.

BTW you do know that Coles 100,150, 175 cams are different between M8s and TCs or did that go over your head?

Stop with all the pi$$ing match BS! There is plenty of that to go around and it's really not needed. If he is going to go with 10.5:1 I would recommend the 150 over the 100 for his needs to run two up and from coast to coast riding. He is not going racing and isn't looking for power to be in the upper RPM range The 150 will do just what he is asking it to and maintain a nice running engine for long life. For the Throttle body question if you stay with the stock size it will limit your power in the above 4000 RPM area but be the same below as a larger one. To the injector question , yes use the larger size ones you listed as they will be needed. Also make sure you change the fuel filter while the bike is apart. Which ever pistons you go with make sure they are supplied with coated skirts as the non coated ones are a waste of time in a Street engine.

Nope. Just don't have any TC charts handy to show what I was trying to show. The basic principles remain the same across the two platforms.
You got me on age. Let's just say I should be retiring, not starting a new career starting at the bottom of a seniority based job setting in a UAW plant. But I'll gut it out another 5 years. Nothing could be worse than getting shot at for a living for peanuts.
The price we pay. The fk'n you get for the fk'n ya got.

Steve,
You're no fun but since you're here.. Do 150 TC cam and 150 M8 cam have the same cam timing events?

Thanks Steve.......Perfect! It doesn't seem that I was too far off base with what I've been thinking. 150 Cams, 55 TB, and the 5.3 injectors. Also, I'll make sure I get coated skirts on the pistons. I had changed the fuel filter and regulator about 20,000 miles ago trying to quiet a screaming fuel pump down, but it didn't help. (Different thread in the past) But I'll be changing all the goodies inside the tank while I'm down waiting for the head work. Cheap insurance, I think.

So, for what it's worth, the valve sizes are as follows.....
Intake- 2.020"
Exhaust- 1.650"

Heads and jugs are headed to the machinist tomorrow morning. I'll start tearing the old cams out after dropping those parts off. Still waiting on a little more info to finish the cam choice decision at the moment...........

Then it's time to go through the whole tranny for evaluation.

What pistons? I had to open up the valve relief on the intake side just to clear a 1.94 on an OE piston
