What changes should I make when using a 350 shot?
What changes should I make when using a 350 shot? First right now I make 403rwhp through a 9" and a 6 speed(just switched to th350) and am set up to spray 150 shot soon, but in a year or two I plan on spraying 350 shot. When I pull my engine to do this I will definantly be putting on 4 studded splayed mains and changing my Ross Pistons cause they can supposedly only handle a 250 shot. I will change my ARP head bolts to studs. I also will get a dedicated fuel system for the nitrous. I already have just about every safety device you can have for nitrous.
Will my eagle forged crankshaft and eagle forged H-Beam rods handle 403rwhp plus another 350 shot of nitrous?
I have a 306 cam, how much of the 350 shot do you think I would be wasting out the exhaust valve with this cam? or is it a somewhat decent cam for nitrous?
I can't remember but I thought their was some special head gaskets I need for a big shot like this? Think they were called Cometic gaskets?
Do I need those hellfire rings? Do these make the engine not last as long, cause I thought they scarred up the cylinder walls or something like that?
Do I need to add cement to my block for this?
I should probably upgrade to a th400, right?
I hardly drive this thing at all but is there anyway with this amount of shot and all safety features that I could have this engine last for a decent amount of time?
Also please if you have any advice or can think of other things I need to do, feel free to help. Thanks a bunch!!!

I thought someone would say that. And no I don't think I am way over my head. Why do you think I am waiting a year or two to do this and alot of this I am just double checking myself. And seeing for example, if somethings are necessary like the hellfire rings I was talking about? I will definantly be using some type of direct port system.
im not really going to tuch thin because i aint got the time..but that size shot on a small block you better have your duckies in a row and yes go with a hell fire top ring and it better be gaped for that size of a shot and i wouldnt plan on running it on the street an no it wont last long if you aint on your tune up..
I don't think your heads are big enough, not to mention the thin deck height, the cam isn't big enough. with a stock stroke you don't need to fill the block, but why not. the 1 3/4 headers are going to hurt you. ditch those 31 spline axles. you need head studs. get a real ignition box, dig 7 is good, so you can run 2 stages and ramp the timing. I wouldn't spray that much on chinese parts either. Building a motor for something like this isn't going to have a 50k mile life. You're going to be pounding those bearings, and chances are at sometime you'll screw up the tune and lift a head and burn some pistons.
it can be done on some fairly inexpensive forged internals, but it all needs to be assembled with the right clearances. you will have to know what you are doing at that level, because the most expensive pistons known to man cant handle a torch. you need to get your 150 shot figured out, and then up the shots from there.
this stuff is like golfing. the most expensive clubs wont do you any good if you have poor form. and, you can play a good game with a set of cheap clubs if you have practiced your form.

i agree.
You got to figure people running that big of a shot at that track are rebuilding there **** every 50 to 100 passes so dont think your going to get a good life span out the motor..it better be your weekend car and start off small and in baby steps..

The only other headers I can get is stepped 1 7/8ths headers right?
When you say not big enough heads I guess your saying there is not enough volume in the heads to hold that amount of nitrous?
Also I didn't think I would want a very big naturally aspirated cam anyways because of the narrow lobe seperation they have. Or is this not what you meant by big enough cam?
The reason I asked about a reasonable life on the engine cause there seems to be alot of streetable supra's with tons of power. So I just didn't see why we camaros couldn't do this.
Yeah I have put on less than 2000 miles in the past year. Also I just posted this a second ago, but I just don't see why there are so much streetable supras with lots of power. So I don't know why we camaros can't do this.
also, if you arent spraying the car right now, you might as well figure on changing up your entire combination. one obvious thing is the gears. that will be way too much gear unless you are running a 30" tire. i would highly suggest putting an automatic in the car. if not, set aside a few thousand to repair broken clutches, lockers, and axles. also pumpkins/pinion supports if yours is a standard one. im sure taner would fill you in on this stuff. even his car would go much faster with an auto.
