Help with cam/stall choices
Help with cam/stall choices I sold my Camaro and ended up buying a 2000 Trans am A4. It's bone stock for now. I plan on doing full bolt ons, cam, heads, rear gear and a converter. The car will be a weekend street car. Maybe see the track 2 times a year. I was looking at a TSP 228r, Torquer v2 or Speed Inc si5 cam with a Yank ss 3600 or 4000. Any advice would be great!
I'd also look into the BTR, Tick, Ed Curtis and other variants of the the 228/232 cams. They make great useable power.
I had a SS3600 and it was nice paired with 3.73s but I upgraded to a 4200. Since it's a weekend car I'd go 4000+ but then again I'm willing to live with less streetabity/stock driving characteristics

With a 3600-4000rpm stall converter I would recommend either our LS2 Street Heat Stage 2 camshaft or our LS2 SNS Stage 2 camshaft.
Although the camshafts are marketed at LS2 camshafts, your engine doesn't know that! The cams will install, run and perform just fine in your LS1 engine.
SH2 specs are 229/232 .615/.575 113+3
SNS Stage 2 specs are 231/235 .617/.621 111+2
The SH2 will have a flatter more linear torque curve with the SNS Stage 2 having a more pronounced mid-range and a "table top" shaped torque curve.
The SH2 will drive better than the SNS Stage 2, with the SNS Stage 2 making the most peak torque and HP.

FWIW my car has ss3600/3.73s with FTI (Ed Curtis) Streetsweeper HT which is a 228/232 cam and others might disagree, but I think a cam this size is perfect for the street. The cam makes power all over and is easy to drive.
My Camaro I built had Speed inc si6 cam, yank ss4000 and 3,73 gear with full bolt ons. I really liked the set up but the power didnt really hit untill the upper end. More of a hwy car. I had stock 243 heads. I'm sure I'll get 243 heads again but have A.I work them over

I think I'm going to go with a Yank ss3600.
Cam choice will be either Tick SNS stage 2 cam or Ed Curtis 228/232 SSHT cam. Any info on these cams would be great. I know they both have a great idle!

Do heads/cam together. That was my mistake. I have the 228R and its awesome. Great power everywhere. Put down 425 on a mustang dyno wit prc 2.5 5.3 heads. Was right there with some of the bigger cams on dyno day.
With a 4000 stall, you can run pretty much any size cam you want to. There is really no drivability trade off like you see with the M6 guys. A big converter, in itself, is more of a drivability trade-off than the cam. The upside is the big stall absorbs almost all of the negative aspects of a big cam.
Knowing that, I plan to step up the cam considerably next time. And my cam has 16 degrees of overlap now. Think MS3/MS4 sized drivability. And the 4200 stall makes it run fun.
