Default WHAT DO YOU THINK. HP #'s

i was woundering about my setup. im putting it all on next week.what you do you guys think im going to have it dynoed after so take your guess.

i have heads the guy i bought them from said they flowed 260/190
986 springs, comp cam 306, pace setter long tubes headers, pcm tuned, 4.10 gears, 1.6 RR bowties i think therefrom the hot cam kit. harden pushrods. spec stage 1 clutch and steel spec flywheel. i think thats it oh if you didnt get the clutch thing its a M6. i know they dyno better the A4's.

i think im going to dyno around 350 to 370 hp but i i always hope for more.

You might want to look into the maximum lift capacity of the GMPP rockers since they are a short slot and you are looking to run a lot of lift.

Then again you could just wait and see what breaks.

yea the GM rockers max lift is .575 and that cam if I remember right puts you right there or a little over with the 1.6 ratio. May want to think about upgrading.

Honestly you need to rethink the whole package. The 306 with an M6 is going to get old within a few months. You should go smaller, if you choose well you will not give up performance but you will gain drivability.

That cam is known to surge badly and the M6 does nothing to dampen it.

will i already have the cam. but what do you mean it surge badly. i really only drive it a couple of miles to work and sometimes at the track. this is kinda a starting point for more power im going to put a 383 or i was thinking of a lsx swap i know everyone says just sell and buy a ls platform but thats no fun.

the car will buck at low speeds and low rpms. it is no fun to daily drive a car like that, or drive it on the street much at all really.

there is an LPE cam in the 211/219 range and a crane 210/224 or something around those numbers, also the cc503 is a 224/230 and is pretty street friendly or a custom cam is always a good idea.

No it wont do better at the track.
A couple years ago I was impressed with a local 306 cammed stroker f-body running 12.7 on street tires.
My car will run 12.7 on street tires today with more weight and less cam.

The 306 is an OLD grind and was popular with the "bigger is better" crowd, a few guyys have gone fast with it but a lot more guys have gotten sick of the poor drivability.

You have to understand that parts being popular is NOT driven by quality or results but by ignorance and marketing. A lot of guys do not realize their results are mediocre and endup telling everyone how great their parts are and just make excuses when less modified cars go faster.
My car has caused many guys with much more heavily modified cars to make all kinds of excuses and false accusations about how prepared my car is, it is easier to do that than to admit I made better choices than the forum as a whole.

For the forums to be helpful you have to dig through a LOT of BS.

High enough to be risky on a stock shortblock.

If you are looking for low end torque you went WAY overboard. The LPE 211/219 is a great torque cam with very tame street manners assuming your tuner is worth his weight in salt. The crane 227 will give up some of that low end torque but make more up top, sacrificing some drivability for some performance. For the same or a few bucks more though you can get a perfectly tame custom grind that still shines at the track.

In a stock cube LT1 there isnt really any need to go over something similar to the 503 if your car sees more street then strip. Sure, the big cams may dyno higher(if you risk spinning them where they want to be), but you will have to deal with more tuning and drivability problems for little to no E/T gain.

Sometimes people go bigger and run SLOWER times at the track.

Better in a 383 than a 350 but still not anything I would call good.
