oh well the ford is paid for.
daily driven trex or similar cam...
daily driven trex or similar cam... ok looking into another ls1 car. im thinking the trex cam for my daily driver. my only concern is finding the right spring so that i dont have to tighten them up every so many miles. so what springs are you running and what else should i replace? ive seen people change oil pumps, timing chains? could i get away with just the cam swap and valvetrain? thanks for the advice.
basically what i want is a nice strong daily driven cam+bolt car with a shot of nitrous in the future.

Unless you are prepared to run badass valve springs and do comprehensive driveability tuning, you will not enjoy the T-Rex in a daily driver. This is an extreme cam and requires a lot of attention to detail. It's not a drop in deal. Tuning is critical with this cam. Comp 921s are some of the best springs to run. Next would be the PP/PRC/Manley duals. You'll need to shim them to within .050" of coil bind for maximum life. Again, attention to details.

Checkout the TSP MS3 and the S Cam...both great cams.

You will want to replace the LS1 timing chain, when you pull it out, you will see why 
The LS2 timing chain is plenty strong and only 30 bux, plus it works with stock sprockets

I think it's crazy to to a cam swap w/out a ported pump myself. Thats like buying a bently and putting hubcaps on it.

If you can say your cam backed out the rocker arm bolts, you've got one badass cam
