Reliability? 400hp stock bottem end

I have 96k on the car right now with the stock bottem end,
I put the cam and had some headwork done at 83k,

Can i daily drive this car to 150k, i don't race it too often maybe 1 good race a month,

My problem is I am going away to college probably at christmas time next year and need to either sell it or keep it,

I won't have a garage or anything at school of course, however i will come home every 2 or 3 weeks, 90 minutes away

my mods are below,


So basically can the stock bottem end hold 400hp for another 40 or 50,000 miles,

I know i will have to adjust the rockers throughout that period and i will put in a new fuel pump before i leave, but everything else on this vehicle is basically new,

what do you think?

2nd option (buy an ls1?) I gotta have my GM RWD V8,

thanks,
Jesse

With only a Hotcam you should be just fine. However, your compression is kinda high so make sure you always run high test, which I am sure you do anyways. With as little abuse as you are puttin on it (1 race a month) you should be just fine. Why do you need to keep readjusting your rockers?

I have ZZ-409 cam,TPIS headers, and all the bolt ons etc.....105K on short block and makes 367 RWHP and no reliability issues. I road race and autocross the car quite often. Works just fine.

I think he means premium gasoline by high test. Like at least 91+.

FWIW, as long as you keep up on the maintenance and don't "abuse" the motor, it should last quite a long time.

Hi test is what we used to call premium back when most streetgas was leaded.
