I know I'm right....
A sticky Nitto/DOT drag tire is the easiest way but they dont last.
Forget HP
Build for TORQUE!!!!
Why new lifters?
@Rat Bastid care to share some more ways to increase traction.
Rollers are transferred over easy enough.Force of habit... always swap out lifters with new cam.

It depends on where your street is. It's easy to beat too much torque on the street from start through the 1/4 mile.
Naw they need to be alive. When they dry out, they lighten up. If they're still alive they still eat cupcakes and fatten up some more.Dead. You don’t have to feed them. Just sayin’
You're weird..lol just kiddingI only used 600 as an example, I've got more.... and I don't get a thrill from burnouts, just look'n and book'n...
This is a classic example of knowing what one wants.

Too many think they want the horsepower, when what they really are talking about is the street power.
Yea I made that up to get the point across.
And a dyno can only hint at the torque and power at street rpms.
Thank you, thank you very much!You're weird..lol just kidding
I've got pretty much that exact motor (the before curve) and I want the after curve. Bad. Motor just feels slow. Fun enough around town when just driving it, but when I get on it (like passing on the highway), just doesn't feel like there is much there. Nice thing is, it shouldn't give up anything down low, but make a bunch more up top. Win-win.
I’d like a similar cam to what Rich Holdner used in duration, but not the wide 114 LSA.
Can you work this out for the various small block displacements? 273, 318, 340, 360?

Real easy as he formula relates. I would have to look up cyl bores and vave sizes. In the US the book is inexpensive and infomative on a number of areas of engine build. In Canada the exchange is about 1.25 to 1.3 so costs go up quickly.

Thanks. I tried doing the math while on a short break from working on the truck. I didn’t come up with numbers that made sense so I did something wrong. So, frustrated & hot, I just left it to do some parts gathering.273-106.9326 with a 1.78 valve
318-103.4599 with a 1.78 valve
340-104.8796 with a 2.02 valve
360-101.6965 with a 1.88 valve
408-100.7280 with a 2.055 valve
I always round down and make sure I have enough duration to carry the RPM I want.
You can’t use these numbers if you want a flat curve after peak HP. You have to open the LSA up for that.
Yes. For a rebuild I use + 0.030 for the bores. So a 273 at 3.66" comes to 106.5. Anything bigger in the valve starts to shroud the intake. I would say a 107LCA would give the most torque. I think the formula for my 289 came out to 107. I have a cam from my 351 ground with 109 LCA I am going to use. DV says a cople of degrees will not do much harm, but going to 112 or 114 will drop peak torque and flatten the curve a lot.273-106.9326 with a 1.78 valve
