M6/A4?? Either way you are missing some required hardware. 4.10s if an M6 stall and at least 3.42s if an A4
That cam is a poor choice particularly on a stock shortblock, going to surge and want to rev higher than is prudent, the car would in all likelyhood be FASTER with a smaller cam.

im guessing your gonna put down 350hp don't really have a guess for tq but id say it will be lower than your hp. definitely need to mod up to get the most out of that cam.

With a T56 anything less than 4.10s is pretty much a mistake. Have to consider the .50 OD.
Think everyone would consider 2000rpms a reasonable cruise rpm??
Well with 3.73s that is 83mph, with 4.10s it is 75mph and with that cam you are not going to be able to try and cruise at lower rpms because it will surge enough to make you seasick especially with stock compression, higher compression would help but not eliminate the issue.

. fine by me though. go with the 4.10s with the m6 you'll be glad you did. Trending Topics

Most of the big heads/cam shops ask that cam specs not be divulged but I do tell people it is mid-220s intake, under .570 lift with 1.6s and under 112LSA but not anything silly like 107. ABA383 runs a cam pretty similar in common specs in his low 11 second car with as you may guess a 383. Point being there are a LOT of overcammed cars out there.

what you 2 just said " you guys sound like my cousin randy " hes a old timer and knows his **** like you 2 especailly StealthFormula cause i read a couple of your threads and you no your **** real good. but my cousin was telling me the samething you 2 are talking about most cars are over cammed. that most of the time running a smaller cam will be better and faster.
he's going to get back to me tomarrow and let me no the deal with whats going on with my car. i told him i want him to do the top end and a custom cam.
he's going to port/polish the heads and intake.all he wanted me to do is find out the weight of the car and tire size im going to be running , also gear. and he'll take it from there
"""speedracer2536'"""" listern to these guys they no there ****.

I don't have a camera, a friend does. Will have to see if he has a video he can put up.
He has a handful of racing videos on his photobucket account.
I like this one, though I had the headers open first time I tried it with this setup and surprisingly found it to not be worthwhile. http://s39.photobucket.com/albums/e1...nt=purgedl.flv LS1 owner too buys purging to lauch so I tree and beat a sprayed LS car
, I actually had 3.42s in the car that night too.
If you flip through a couple you can hear the car a little through the dragstrip backround noise. As luck has it late fall is always busy for the guy with the camera so I don't have any videos of the car faster then 12.1.

I would guess that your going to put down somewhere between 345-355rwhp but more towards 350-355. With heads keep in mind your going to have to shift it even higher than on the stock heads so if the bottom end isn't built it may not last very long shifting it just under 7k where it will want to be. If your planning to build it or it is built then it will work just fine.

The only "problem" with stock bearings is the rod bolt stretch at high rpms, not really a bearing issue. I do not know what bearings will cope with that best but maybe talk to someone knowledgable and see what they recommend.
The stock oilpump is pretty good already setup much like older ones after blueprinting and modification. I like to just put a $2-4 high pressure spring in it and a $7 melling metal sleeve shaft to turn it.
