I use to be a Vol firefirghter but had to take a leave of abscent because of school. I also use to work for the Ambulance district here but did not have the time to put in with them so they laid me off. I work 40 hours a week and go to college half time. Thats enough for me.

So I know I have talk about doin something to my motor for some time now and never got around to do it..lol.. I got my payments on my car down to 130. Now I'm saving my self around 700 a month. I want to do a forge rotating assembly, forge pistons, heads and cam. I figure around 4500 for both from Texas speed. I know there will be more I will have to spend but it's just a ball park figure. I wanna spray a 150shot so I need to know what type of pistons should I use? There are so many differnt types of set up it's got my brain spinning. I wanna maybe use the same heads as Joe got but would those be good enough to spray with and last a long time.. I wanna a big cam, but I have read alot about people useing smaller cams for N2O. Why is that?
Any info would be good thanks!

here is the latest on my progress
i have the cam in the car and it has been degreed to 109 centerline(thats right on ther money) i got the timing chain back on and i have the new oil pump installed along with the front cover. i have the lifters in all i have left is put the heads on th intake manifold bolt the headers and put together the front of the engine, im really hoping to start it up tomorrow night.

People that spray regularly go with a smaller cam because they don't need to spin the engine high on the bottle. It makes for a more reliable setup by keeping the rpm's down. Here's two fictional examples:
-Big cam 408 makes 530rwhp + a 150 shot (680 total) but it peaks at 6800rpm
-Small cam 408 makes 500rwhp + a 150 shot (650 total) but it peaks at 6200rpm
The smaller cam engine will last much longer (safer rpms) and be easier to tune on the bottle.The smaller cam engine would also be safer to tune for a 200 shot.
There are quite a few good piston makers around. Diamond, Wiseco and Mahle and are very good and will easily handle a 150 shot. If you're looking to go with anything bigger than a 200 shot then I'd suggest a mandatory 2618 alloy. Some of Mahle and Wiseco forged pistons use 4032 alloy which are strong, but not really made for big nitrous or boost.
Send me a pm if you want and I can help point you in a good direction.
