NOS cam suggestion

Ok I wanna throw out some cams here and see what you guys think would be a better cam for a 400 shot on a progressive setup.....

cam 1 cam 2 cam 3

Dur@.020 305 / 317 Dur@.020 301 / 314 Dur@.020 306 / 318
Dur@.050 272 / 284 Dur@.050 271 / 283 Dur@.050 275 / 287
Dur@.200 189 / 201 Dur@.200 191 / 204 Dur@.200 197 / 206
Lift .746 / .746 Lift .742 / .738 Lift .738 / .738
112 LSA 112 LSA 112 LSA

cam 4

Dur@.020 303 / 321
Dur@.050 273 / 285
Dur@.200 193 / 201
Lift .742 / .774
112 LSA

Steve if you read this I would like to e-mail you about what I am doing. It has been a pain to try and get time to talk to you.
I figure a 112 LSA would be a good starting point weather it needs more or less. Any ideas? I am probing to see how far off I am on this.

whats the rest of the specs on the motor, car, etc?

You gonna make me give out my G14 classified, top seceret stuff? I was curious how the lobes and basic setup would work with a 400 of N2O.

might work good for a given combo and not so good for another...............

OK here it is....

554 cu in
trick flow a460 heads..... flow #'s as follow.
2.35 intake / 1.88 exhaust
in / ex
.100 80 72
.200 170 134
.300 251 182
.400 325 227
.500 389 271
.600 430 312
.700 455 345
.800 463 364

13.0 compression

flat top pistons
1195 BG king demond R/S carb..... if I can find the 1295 sleeves thats what I will go with.
6.8 rods
4.3 crank
4.530 bore
thinking 2 3/8 headders or mabe bigger. I am gonna custom build my own
turbo 400 trans
3.55 gears
max rpm's up to 7500.
stall I still need to figure out cam but was looking at a 3500 on motor.

I dont think any of those are enoph cam for 400 worth of N20, i will look at home i still have a custom for an A headed nitrous motor and will post the specs for it.

cool thanks.

Yep...more duration, more lift and a wider LSA.

I just want to throw out a few things here. I don't want to spin it to the moon to make any power without the juice like 8,500 rpms or more. I know it will not run N/A like a N/A cam. Oliver rods, scat 4340 crank, and diamond pistons will be good to 8,000+ rpms, but like we built my 521 SCJ, Lem it worked awsome for me, I know you like it as well. It is not using NOS every pass, but have the capibility when a grudge race does present itself.

destroke it and spin it 9000 rpm..............

Hell just take to 12,000 itll take and mo powwer to.

Even N.A. you'll need more cam than you have listed.

Ok so I am way off on duration, what should I be looking at? 276/288 range and what about the LSA? 114? My next list of cam profiles are going up to a .800 + or - a little.

Just let Lem spec. you a cam and qiut gessing

It's not about guessing, I am trying to learn about different motors I build. I am going off the last one I did and a basic desktop dyno to see the what, why, and learn the results. Hey Lem I hope they don't kick me out of the seminar this month for asking to many questions.

285- 290 @50 intake 300 -312 @50 exhaust 114 lobe separation 114 center-line 800 plus lift intake and 780 -800 plus exhaust probably install at 112.


But i would probably call Lem and tell him to get to work and have my cam here this coming week no excuses

ive got a baby cam compared to those #'s

I just put up 2 cams for sale, one of them should work really good with 400 hit of n20 with a460 heads
