Canned the car with 40k- ish miles. Currently at 75k miles. Don’t track the car, weekend fun runs if I have time. Boosted the car with 74k miles, and that was last year in May.

BTR springs the go to still, or is there anything better? I’m assuming prolly needs a retune?

I'm running pac polished .660 springs and have gm performance lifters. But my valve train is pretty noisy and I don't know if it's the springs or lifters or s combination of the two. But everyone says it's normal. I've had them for about 7k miles and haven't had any issues so far. I even did a look under the valve cover and they looked great still and I beat on it every now and then. lol 😆

FBO and cammed and stalled, just refreshed my BTR .660's after 23k. Running GM LS7 lifters and Smith Brothers trunion's.

I tend to favor PSI ML1511 or PSI ML1516 beehives for various reasons. Have yet to see one break either.
