Sup guys, haven't been on much since i haven't had my car on the road, but i'm finally putting my car on the road after a long winter. Anyway, i've got an 88gt 5.0 with some trickflow heads,trick flow track heat cam with 5.10 lift, full roller, edelbrock performer upper and lower, bbk 65mm throttle body, 1 1/2 flowtech longtubes into 40 series, built t5, 3.73 gears. But as i was doing a teardown on the motor, i found out that my lower end was bone stock. So, i figured the lower end should be rebuilt. I ordered a scat rotating assy with forged crank, forged h-beam rods, forged dome pistons and i'll be taking it to the machine shop to get it hot tanked and bored .030 over. But, i just have a few questions about the stroker kit; I was wondering if i need to turn up my fuel pressure to compensate for the extra 29ci. I also ordered a nitrous express direct port kit, and was wondering what shot would be safe, Because i should be up around 9.7-10.1:1 compressions, and i heard spraying can be a little sketchy with high compression. Anyway, she should be back on the road in about a week, so i'll see you guys around, and thanks for the help.
With a 331 and spray you will probably have to have a chip made and tuned. The headers are too small for your application. You will probably Have to increase the injector size. If the motor makes a good amount of power n/a then the nitrous might put it over the threshold that the block can take. (If you are using a stock roller block). I'd look into studding the main saddles with ARP Studs.

I figured i might have to get it tuned for nitrous, but as for the headders I don't know if I can go any bigger, 1 1/2" individual pipes off the head into a 3" collector isn't big enough? And I forgot to mention that I ordered a moroso girdle for the mains with ARP studs to give the block some extra strength. I have 24# injectors right now, what size do you think would be good?

You don't need to get the car tuned for nitrous . You just need an ignition box that can automaticaly retard the timing when i'ts activated and a fuel system that can keep up with the fuel demand ( I.E. .. Fuel pump , Bigger fuel feed line , fuel rails . ) As far as inj. I'd say 36's .. A wet system doesn't rely on the injector's for fuel , but it will rely on the fuel pump to keep up with the volume demand .
The Main cap girdle will help keep the main caps from flexing , But won't do anything for the lifter valley where they are known to split right down the middle . Someone makes a girdle for for the lifter valley .... Can't remember who though . Even with a girdle ..It would still be a time bomb if you make more than 500 rwhp .
I agree that the primary tubes should be at least 1 5/8 ... , but I would go with 1 3/4 . You'll know if the tubes are to small as it will feel flat in the upper RPM 's .... It will Rev , but it won't pull !!

+ 1,000,000. One of the beast ways I have ever read it. A window switch would also be a good grab for a consistant/ safe N2O setup.
