This grind, with it's tight 106* lobe spacing angle, has a pretty rough idle, Crane lists the powerband as 1800-5400. Crane states this cam is good for 8.75:1 - 10:1 compression ratios.

Kenny, this cam may satisfy your buddy's "cam music" desire and still give good performance. Here's some YouTube videos of this grind:





dam that sounds nice, i dont want to hijack this thread but anyone know how much overlap that summit can has?

im currently running the summit 224/224 cam in my twin turbo camaro, while it is pretty much the ideal cam, i wouldnt mind giving up a lil power for a meaner idle. the 224.224 almost sounds stockk

with my tpi intake im only good to spin the motor to 5,550 rpms after that its tounge is hanging out and by 6k rpms its all over


how well do u guys think that would work on my motor

355 sbc
9.2-1 cr
ported 882 heads
ported tpi intake
twin 57mm turbos

my ex system consists of dual 2.5 inch downpipes that are about 4 ft long each

eventually ill be going with a 2,500-3k stall converter when i swap in the 4l80 trans , but my rear gear is going to be staying at 2:73's

cam/overlap

Having the 106lsa and a lot of overlap can be used if everything else is setup right, especially with some stall to get it into the useable range, but for a turbo or twin turbo app. you can't use a lot of overlap due to the fact that you are pressurizing the intake charge and will push cylinder pressure out the exh. ahead of time, naturaly asperated won't as bad, so have to stick with a smoother idle, but power galore. Why such a tall rear gear ratio, man sounds like 200mph with a 2.73, the turbo's would come in a lot quicker with a better ratio like 3.42's and won't need too much stall either.

turbos come in off idle and pull all the way to my 5,500 rpm limit
and yes i plan on doing 200 mph with it down at the salt flats this year just need to get some more saftey equipment before the car is legal to go that fast on the salt.

not to mention the speedlimit on the highways here is 80mph and ill be dailing driving this car for the most part, and i make a few 120 mile round trips a week. so want to keep the low gears for milage

Man, 80mph there, nice, real nice. I bet there is a whole sh@t load of safety equip for running that fast, can see why the 2.73's then, makes sense. Have never done that, but used to go on road trips on our Northern highway's at 150mph for extended periods on 3 different street bikes I had when younger, glad to live past that, but was fun, so doing it leagally on the salt would be pretty sweet.

actually its not to bad, ive built the car to go 9.0's at the track and be legal, so i dont have to add to much for the salt flats to be legal, there are a few things though that i need to do like remove the steering wheel lock, and disabling the door locks

9.0's

So at 9.0's you must be fully caged and what 5 point harness, how about fire system for either is it needed too, not for 9.0's but what about the Mph on salt. have you ever raced on the salt at all and if not do you start in the lowest class and work your way up to be legal each time, i imagine a lot of diff classes too. what else is done on your build, suspension too.

10pt cage,fire suit 6pt harness for the drag strip plus an nhra comp license

for the salt i have to add in a fire supression system 5lb engine, 6lb in drivers compartment, need a different drivers seat, hans device. i will run the 130mph class the first day, 150mph class the next day, then whatever liscencing passes i need to make before i run 200+. this will be my first time ever on the salt. even if its ur first time u can run the 150mph class with nothing more then a 5lb fire extinguisher and helmet with a bolt in rollbar

im keeping the front suspension stock for the salt with the exception of 1.5 inch drop springs. on the dragstrip i have some poormans 90/10 struts and drag springs.

for the salt on the rear ill have 1.5 drop springs , 3 way adjustable shocks,lcarb, adjustable lower control arms, adjustable panhard bar

the only difference is for the drag strip ill be using the stock springs instead of the drop springs


when i do the 4l80 trans swap ill be doing a short tq arm setup with the mount moved to the crossmember instead of the trans tailshaft

Ya I agree on the crossmember than stock on the trans case, they take to much abuse there, had to modify mine on my 2000Ws6 trans am I had last year, to much abuse for the trans to take, also the panhard bar stock is crap too, modified it too. The 4l80 will be a nice change, buying a modified one I imagine, what brand. That's where your stall will come in I see.

I am looking at a TCi Street fighter #371000p1 700r4 trans kit with 2,400 stall convertor for my neighbours 72 Gm 2wd truck that was a 3spd std trans and all it needs according to TCi (it is included) is lockup kit for 4th gear. Seems like a good buy for $2,400, includes fully manual trans for 400hp up,cooler/synth.oil/dip stick and only putting it behind a 400small block at approx 420hp. Know anything about these trans.
