Sure but it's such a pain (no retractors for shoulder belts) who actually uses them? I didn't.

Wow! This is awesome. What a great running combination

Oh I'm not up to date. You're quicker than me already. Very nice!

Thanks guys! BSB67, your car is awesome as well. If you put headers on that thing I'd have to run for my life.

Not crazy fast but a fun street car.

How old are the tires, what pressure and sufficient burnout? I got a 1.619 60ft with road race tires, manual trans, 4.56 gears and ss springs. Gearing is torque multiplication so a numerically higher gear results in more wheel torque.

If you don't want to rev it why not stick with a stock cam? I would think even stock 6000-6500 would work great. I have a comp cams 24-601-5 227/249 107. Having had it in a "stock/crate" 426 I wouldn't recommend using it but may be a usable core for you?

I use no gasket. Clean with lacquer thinner and a very thin smear of rtv. (I like Toyota fipg). I did this on my hemi years ago with TTI headers. Filed them to make sure they were straight. Red loctite on bolts. Perfect.

I have zero brand loyalty. Looks like a super nice survivor! Congrats and enjoy. :)

Not sure about coolest but I like my stockish aftermarket wheels.

Not a fan of rev kits myself nor do I think weigh matters on the lifter. I see high end titanium valves. I've never seen a titanium lifter. As for turning 6800 with a rev kit and 10lbs on the seat, I think it would be very unhappy and your pistons were probably closing the valves.

It's not always obvious. :) The other effect there is that if it has say 150 seat pressure and 400 open and 1.5 rockers the pushrods/lifters are actually seeing 225/600 lbs

The lifter and pushrod weight don't seem to influence much as it's moving 1.5 -1.8 times slower and less distance than the valve side. (whatever the rocker ratio is)

Weight will make MUCH more difference on the valve side. So lightweight valves, springs/retainers/locks are very helpful. Rocker weight can make a big difference. Pushrod weight and lifter weight I'm sure can influence things but it doesn't seem to. So you want the stiffest pushrods...

There's some movement but much less with a polyurethane mount. I use a rubber strip.

They are great cars IMO. Only car I bought new was an 07 Z06. Built it with twin turbos then realized I have more fun with naturally aspirated stuff. For sports cars now changed to F355 and 993 C4S

It's not just pressures but can also be weak pushrods, springs very far away from coil bind at max lift, heavy components (large diameter springs/steel retainers, heavy valves). Just my guess as my 426 hemi dyno looked just like that when I first got it. (And it suffered from everything I...

This dyno? https://www.forbbodiesonly.com/moparforum/threads/hawkrod-is-doing-the-2023-hot-rod-power-tour.262286/page-13#post-912558901 If so, loss of valve control IMO

Nice! I was planning on switching to the TKX but have had no problems with my TKO. (Shifts nice at 7,750)
