I was browsing yesterday and came across your post. This is a great forum for information gathering and likely making new friends. I live in PoCo and have a 2018 2SS A8. I'll start by saying my kit came with 7.700 3/8 chromoly LS7 pushrods. They were the wrong length and I needed to exchange them for 7.850 rods.
I ordered my kit from TSP. A local shop "Racing Greed" did the install and tuning. Very happy with the results. The kit was their Gen5 LT1 VVT-1 camshaft with factory fuel lobe: 227/231, 635"/635", 116 LSA, 110.5 ICL. Came with springs,seats, Ti retainers and 0 degree phaser limiter plus all associated fasteners and gaskets. A LS C7Rcam chain, TSP roller tip rockers(probably the reason I needed longer pushrods) Comp Cams lifters and a DOD Delete kit.
Other mods are a Chevrolet Performance CAI and axle back mufflers, 1 7/8" long tubes I had ceramic coated in Langley(catless)
Best pull was 504HP and 478 FT/LB on Shell 93, several pulls were 498/476
I can live with that. I would like to add the newer Vette intake manifold in the springtime,but thats it for now.Hopefully I can post up my graphs soon and finish my signature lol. BTW it was on a Mustang dyno
