I need some cam help, i know you say to call comp cams and what not, but i have done that, and i want to get the people here to give some suggestions.....

350 engine, freshly bored .030 over, 9.72:1 forged pistons, Pro Lighning Iron Heads 200cc 64cc, Holley Stealth Ram Intake, Rocker arms will be stock 1.52 for a while, will upgrade if needed later, I think the rest of the Info is in the SIG.... help me out yall, i know you all know more than me, but i gotta order a cam soon, and put it all together.... the money is waiting.

 

i can give an answer or two, but first do you plan on using a custom chip or just upping the fuel pressure? also, is this still roller cam?

 

yes it is a roller cam, yes i will have an adjustabel fuel pressure regulator, and i hve the jet stage 2 chip right now, but eventually will have a custome chip burnt by ed wright.... also i am considering a 383 stroker bottom end... instead of the regular 350

 

well, here are some cams you can use with the chip you have and still get decent numbers. the powermax 2032 from crane, the xr270hr from comp cams, or an LT4 cam. stepping up to a customer burned prom will leave room for more, but that's a decent start.

 

that cams Specifications:
* Advertised duration: 270 intake/276 exhaust
* Duration at .050 in.: 218 intake/224 exhaust
* Gross valve lift: .495 in. intake/.502 in. exhaust
* Lobe separation: 110 degrees
* RPM range: 1,600 to 5,400


My car is gonna have rpm range for 2100-6500 so i need a bigger cam than that....
I am looking for duration at .050 to be around 224/230 , gross lift to be around .530/.530 and a lobe seperation 110-112

I know i will probably have to get a new chip burned, but i do not want ot have to change the cam again later

 

your going to have to upgrade more than just the chip to be a 6500rpm set up.

 

could you be a little more specific than that?

 

You're 224/230 .530" specs sound right on to me. I'd have someone make you a custom grind with those specs. Or call TPIS, I don't remember what the specs are for their ZZ-X and similar cams, but they could tell you.

 

If you are going with the Stealth Ram and planning on using all that new upper end HP, I would also look into a higher stall convertor, that 2100 stall in your sig will kill you.....

 

Agreed, at least a 3000 stall and 3.73 gears.

 

sorry, i was running out of time to be more specific. the torque converter is a problem as they've pointed out, mass air flow sensor will be a huge restriction, fuel injector size, etc. i'm not picking on your set up as it's pretty nice, just going to be hard to get it all to work together.

 

i am not saying i am gonna be running hte car up to 6500 rpm, i am just saying the stealth ram can flow that high, and all the things that you pointed out as weak spots will be upgraded shortly, but i can not afford it all at once.... I did not know they made differant massa air flow sensors though..... can you give me some info on them, or point me in the right direction

 

on the mass air flow sensor, i recall a company was working on a conversion to use a mass airflow sensor from an LT1 and i believe it's out now. if i get around to looking it up i'll get you the number. the more common thing to do is convert to speed density as far as the maf is concerned though.
