What kind of pistons come stock on a 1984 firebird with a 305? and could hypereutectic pistong stand up to a 150 shot of nitrous if not what about 100 and if not 100 what could it stand up to?

 

You know the old saying you never know how strong it is til you break it. I'd say 100 hp and timing retarded properly you'd be alright stock short block 150hp is doubling that 305's stock output. I'd say it'd probably trake oit at least once.

 

Ohh well Its not like it will matter If I blow a motor any way right? maybe I can finally get that 383 Ive always wanted

 

upgrading your fuel pump is what'll help the most.

an N20 kit to give say 75 HP, is about $400. Plus $80 or so for a few seconds of spray.
Let say you use it for a few weeks, rack up $300 in N20. Now you've spent $700 to go fast for a few minutes.
Compare that to a cam, CAI, headers. Now you can basically have the same increase in power, for the same price, but it works all the time.
I'm not a fan of N20 in the least.

 

Agreed. I'd say do exhaust etc.. first, then go with N2O.

 

The cars in the shop for a new cat and brakes...I allready have a exhuast system there putting on as well its a dynomax but Im gonna change the muflers in a month or so... I already have a cam,headers and an intake manifold Im just waiting to see If I keep this motor after I get the 5 speed to install them the reason why I posted this Is because I was wondering If I get the 383 stroker I would blow it up with a 150 shot

 

oh ok, I thought you had a stock LG4 pos....

ok ok, so you want to spray the 305 until it dies, then move some parts over to a 383 and continue to spray? 150 shot?
That shouldn't be a big deal, you can get a N20 based cam if you're really serious about it, but you won't need it.
hyper pistons, and a overly large fuel pump and lines should be fine. Basically (to quote stepheniroc I think...), build the motor to be strong enough to withstand the motor HP, and the spray HP.

 

oh yea, what the heck is with the whitewall tires and oldsmobile hubcaps?

I guess the sleeper look...

 

Seeper look now after paint Im getting ground efects and some torque thrusts

 

Why not go 350 shot then and do it right!!!!
