Circle D 4C+3.73's+full weight= help?
 

Looking to add power.

I got 2 friends that are running 100&150shots and it's time to play catchup. My motor has 134k on it and has full boltons w/ a frost mail order tune.

Questions I want to ask.

- should I spray my motor to get the most gains now while my engine has some life in it?

- or should I put my money into the motor itself, and have the full time power and character of a cammed car?

- if I was to spray I'd run no less than a 100 shot.

- also what cam(s) would work well for me?

- I've also tried searches and really couldn't find the info I needed

- when I get the money I plan to have a cam and spray. Jw from experienced people what I should do first.

I have 129,000 on the clock and my concern for myne is what can I do to make optimal power without hurting the engine. I personally am not going to spray because it will probably spin a rod bearing or other damage will occur. But check into low 230 duration cams or a 228 230 and a 100 shot will be great as long as the nitrous is tuned for it there will be no problems. And for longevity get a tsp ls6 ported and shimmer oil pump !! Just my 2 cents

Well if it was to spin a rod bearing I'd buy a used shortblock for fairly cheap.

Definetly planning on an oil pump regardless which one I pick.

by the time you include the n20 system, the bottle heater, the purge, etc. you'll probably spend as much as a cam, springs, and pushrods.

What kind of times are your buddies running at the track?

After some thinking I think I've made my mind up.
- if I was to cam my car, and say I blew it up, theres that money gone..
- if I was to spray my car, then the money I spent would still be there, just pull the kit off the car and putting an iron 6.0 in it and upping the jets :)

1/8th is bout all we run.

100shot buddy- lol, just getting his kit working today so no times.

150shot buddy- has only been to the track on a 100shot and netted a high 7.4x low 7.5x. So figure 50 more HP in to get what it will run.

Also a question I wanna ask some people...

Who's runnin a 200shot? I know it's been done quite alot. But should I stay with a 150 for longevity...

You could still use the valvetrain from the first combo into the new shortblock but reccomen going a big cam if you go 6.0 but save all the headache and get the n2o for sure and def 150 shot with a good tune for it. Or for the Hell of it 175 shot

Now were talkin.. All this I'm too scared to do this or that.. Puhh wack

I run a 4c 3800 stall, with a Torquer V2 and full bolt ons with 3.43's and car ran 12.62 at 108 tonight. I gained almost a full second with the cam and converter so I'd say cam that BI**

Thanks man! I've been reading on nitrous and tuning. Ppl suggest my friend to "dyno tune" his 75shot. Lol, with that being said. I might aswell go ahead with a cam.

- a torquer v2 was in my mind also.
