Is this a good turbo cam

[BaldMenace]

Building a turbocharged Buick 300 V8. Using TA's V8 version of the gn heads. JE turbo specific pistons etc. The cam card is a hydraulic roller. I've never seen a cam with -13° of overlap before. Just curious if this will work well.

215/215 on a 114 lsa.
It’ll have good vacuum. That’ll be important for vacuum brakes.
Kind of a mild/mid range street turbo cam.
The 114 LSA gives it the extra negative overlap and closes the intake a lil later which will give it a lil extra rpm.

That is very similar to my DLS 210-210 with more lift. as fare as when the valves open and closes .It kinda old school but it seems to work good with new turbo tech

My concern was negative overlap in other words less than none. It would seem that once there is no overlap there is zero chance of reversion so what's the point in going so far the other direction?

Im no engineer and not had it on a Dyno my car is very nice on the street and with vacuum brake and a ball bearing turbo I have never been without vacuums to run the booster. its smooth as glass on the street and has gone 10.8. And again that is old school tech. Im sure there is grinds that are better and some could recommend something better, but someone put that grind together with more smarts than me. And we may have new Tech. turbos but TA heads are not LS are Coyote we have exhaust ports and headers that is less than Hi Tech. I know where there is a cam that is a better fit for my combo and ill get over there a get it someday and it has very nearly the same overlap. It may not make the most HP but I bet at will have good drivability.

The negative overlap is at .050 lift, you still have some overlap below that. One of the goals of that grind may have been to limit the total overlap below .050 lift. I would not begin to think I could sum all the variables and say what and why it works or does not, but BeatV8 gives a good overview. It looks like a safe pick for a street cam and would not be influenced by turbo back pressure much, I would roll with it unless you have some special goals and components you are looking to optimize.
