i just did a search for your question(s), as i have the same. so far, after searching for...3 minutes i've turned up 3 dyno graphs with stock heads in an automatic.

thank you. now please give them those links. and teach them how to search.

the t-rex has been beaten to death in here. the answers you search for are out there. its not a gentle cam, you'll need a big stall, and gears to tame it. not to mention a tune and most supporting mods(ie full boltons - or close to it).

I got a 4000 stall and i am going to install 4.11 or 4.30 gears and i have all bolt ons. Why did that guy say good luck is it hard to tune

FloridaZ

i would go with 3.73's. Acctually i am. Same cam too. Only a little larger stall.
4.11 would work better with an m6.

giving them the links from my searching and effort is like letting them copy my homework. if i can do it, they can, too..

That cam REALLY likes the RPM, i guarantee that 4.10's aren't gonna hurt at all.

So did I? search and found. But good luck on the install I heard on autos cant run the Ac with out some problems with it cutting off. Tune it to work with the ac but you get some power loss. I heard this from guy at thunder itself. hope you never run the ac in traffic or in the city only hway. or take it off.

I have 4.10s in my auto... i love em... with a 4000 stall... with the T-rex driving in traffic will be easier the more gear you have (higher numerically)
4.30s wouldnt be a bad idea

He said good luck, cause it's big and you will most likely have problems in the auto if you don't have a dead on tune.

My HP numbers are below in my sig with this cam and TSP 1.5 heads on only 25 degrees of timing for a safe tune for my n20 made 427 for the motor at 27 degrees

Low vacuum and brake headaches, surging like a ****, hunting idle just to give you a few.
There is a cure however, but it is very costly, but if you want to be RAD.
Independent TBs and SD tuning will make this cam purrrr like a kitten.
Harrop racing in Aussie land specialises in that.

SEARCH!!

For a true street car I'd go a little smaller. LG G5X3, TSP MS3, something like that.

I ran it with my A4, no problem once I tuned it, which takes alot of patience and time (for me anyway). It only surged a tiny bit in reverse, otherwise ran great. I stayed with my 3.23 gears and a 4K stall, although 4.10's would of been better if you don't run N20. The trick to run a big cam in an auto with the stock gears is knowing how to tune the tranny shift points for part throttle and lock up. It is a pretty big cam for a DD though and plan to spend some time in the 7K plus RPM to take advantage of the Trex as well. I did 430 RWHP with out the FAST 90/90 setup. Unfortunately, I'm almost an M6 car now and will never know what improvement that would of added..

what about the "s" cam by HPE?

blkZ28spt

Looks very similer to the MS3, but on an even wider LSA. Not a bad consideration.
