Thank you Gordo. I don't sweat it. Not everyone understands or has seen the difference in dynos and performance by all the different transmission, drivetrain and tire and wheel combos. I have been doing this for a long time, but I can see how it might look to someone who has not.

Maybe .0001? You likely could not measure it. Its purpose is to deliver extremely consistent surface texture.

If you have a carburetor, I might be able to help. I don't tune EFI, so I would be no help there.

@@camshaftsteve I understand… well can you offer suggested MSD timing curve for a LS 6.2

Manual or automatic transmission? If you have an auto, at what RPM does the stall torque converter stall to?@@akp41

@@camshaftsteve Thank you for responding… LS 6.2, MSD box, FiTech EFI throttlebody, Auto TH350 with a 2800-3200 torque converter, and 3:42 rear gear

That engine had T&D 1.7 shaft rockers.

This camshaft did not have a ton of overlap, so plenty of vacuum for even the old school brake booster.

I do love me some turbos. Who knows, there may be one or two in my future..... :D

This engine had Dart Pro1 LS3 heads as cast.

.689" lift. with these springs: cammotion.com/valve-train-parts/valve-springs/ls-premium-street-strip-750-double-spring-set/

How has it been holding up?

I sold that engine to my friend Andel years ago, but it held up like a champ. Never even needed adjustments when checked once per year. Truly a rock solid setup.

Yes, but I have upgraded to a procharger combo and an even more aggressive Cam Motion LLR camshaft

I get this question a lot. It went like this: When I first got into LS engines, I was trying to make this a simple build that I could tune myself. I was very good with carburetors and I loved the simplicity of the MSD box. So, I was kind of doing what I knew at the time. I felt like I was keeping it simple. Once I had some success with that formula, I saw no reason to change on subsequent build versions of this car. For me, it worked and I had tons of fun with the project.

Yes, the same popular .660" valve springs. They did the job just fine, but would have struggle on a cylinder head with heavier valves. If I were to do it again, I would use a spring with about 30 to 40 pounds more open pressure.

I made it all myself. The switches themselves I think were old NOS brand units.

Old school N/A does have a very certain personality. If you love it, you love it. I get it!

@ssameerkartha, I retired from Cam Motion in the spring of 2023. Or, I would check it out and report back. I can't remember the manufacturer of this unit.

@@camshaftsteve thanks a lot. we also make similar machines in India

300" Buick V8 originally.

Zach Wild a "medium" amount. :D

The LQ9 held up like a champ! Derrick. I got a great deal on a stroker kit, so I built this engine. The old LQ9 was sold to a guy in Colorado for a grudge car.

speedtigger that's great! I'm still trying to get my LQ9 right, I'm fuel injected so I ran into quite a few tuning issues.

Yes. Extensively

Supposed to ship in 10 days.

+speedtigger Nice !

👍

It is stuff that Comp Cams makes. I use Cam Motion for all my camshaft and valve train now. Cam Motion is quieter and better quality.

I kind of like the 2 degrees per 50 hp of NOS to get in the ball park. Then watch the plugs and performance from there.

The 10 bolt had 3.90 gears. When I upgraded to the Dana 60, I used 3.73 gears.

Dual 3 inch with a Pypes x-pipe and Dynomax Super Turbo Mufflers.

It's tough to get a good tone with the LS but yours sounds real good. May have to try that exhaust combo on my s10...

Yes, either would work quite well.

If you take out the lash of cam it is about the same as hydraulic. You have to account for the valve lash

Given the cam specs id say thats a Lq4 or lq9 truck engine and the power looks right. But what is with the small cam choice on the solid roller? Racing Regulation?

That would be a fun test. I have threatened to do a back to back test many times, but never got around to it. In my opinion, it was a little of both. A little bit of the specs and a little bit of the inherent power advantage of solid roller.

Not quite. The Solid still had more net duration and more net lift than the hydraulic did. But, you are right, on this low lash, you would subtract about 4.5 degrees of duration to make up for the lash used by solid lifters.@@tamanko21

No regulation. The limiting factors on duration were piston to valve clearance and for lift a reasonable lift for good valve spring durability on the street.@@drewnashty

+A&S Lawnscapes That was a 6.26 @ 109. The trans for that pass was an Extreme Automatics TH200-4R, I am currently upgrading to a 4L80E.
