Thank you I just did most of what you are describing here is what I did if you care.
1 Re-gasketed everything I could while the engine was out.
2. Cam - TSP 228R with .600 lift and 112 LSA
3. LS7 lifters
4 Double .660 springs locks and retainers
5.Cam chain and sprockets
6.Chevy performance oil pump
7.BBK 1 7/8 headers
8. Ls1 Trunion upgrade roller rockers
9. Front and rear cover plates
10. Already had 3:42 gears and an LS6 intake
11. I also picked up some used 243 heads that were in good shape.
12 Tune with four dyno pulls car made 401 HP. rotating assy had 150k on it.
I'm sure with a different cam, as the 228r is not a radical cam, you could easily make 420. Learn how to drive at the track with some good tires and it could happen.

Franz,
If your goal is consistent mid-11's at full weight, I don't think you'll get there with only the mods listed on the Slohawk quote. I'd guess more like consistent high 11's or low 12's depending on D/A and 60'.
Good luck and Happy Thanksgiving!

^^Thats Awesome . I finished up what I'm doing with my car. I opted out of doing rear end gears I have 323s and I'm just scared of it blowing up so I don't want to invest money into it. So my final list is cam kit.. 3600 yank converter..trans cooler.. fast 92 with 92 TB. Ls2 water pump. Tsp headers and catted y pipe. And slp lid. The total is going to cost me anywhere from 6500_7 with parts labor and tune. I hope it's on the low end.

To be honest I think you are wasting your time not doing headers with a cam like that. You will probably not hit 11s without doing headers. The cam is going to be choked out from the stock manifolds. Save a little bit money and do it right. Plus when you do go to put headers on you will need to get the the car tuned again which is more money

Steve, he's added headers to the list in post #25. Who am I? But I agree with your comments on the headers, also a little bigger cam than the 228.
Franz, check out this thread: https://ls1tech.com/forums/11-second...1-831-a-5.html He's running mid-11's with an LS6 intake and cam but has 3.73's. Opposite of what I recommended so you might pay attention to his build instead of my advice. His cam is a little bigger than the 228.

Thanks again gesto! If I do gears after the Dyno tune will I have to retune it? I have 323s but I didn't want to invest too much into this 10 bolt

I would not be the least bit concerned about the 10 bolt behind a auto. I have 3.73's in my 10 bolt and pull 1.5x 60's on it and am not remotely concerned about it

Hey guys I just got my car back.. it drives like a whole different car. It made 383hp 342 torque on a Dyno jet. I love it. I'm bringing it back to have the tune adjusted a little more it's surging a little when it's cold and it's only 20. Degrees out. Also it seems like the cable is getting stuck if I rev it. When I start it it usually revs down to 800-900 but if I rev it to like 2_3k it will only come down to 1500

Gotcha. Depending on the DA and elevation your times seem a bit slow to be honest. With average overall track conditions you should be trapping more like 115 or so with your mods. How's the tune? What's the AFR and timing at?
