how do these cam specs look? 224/230
in. .567
ex. .578
on a 114lsa
It would be going in my stock lq4 with a s88 on it. My buddy bought it off a member on here who had it ground for boost/nitrous and can get the cam for next to nothing. I plan on building the motor next year or so and getting a custom ground cam for it but how do these specs look to run now?

A few years ago, I ran a comp cam, n a consistent bracket car. I swapped to the same grind numbers in their nitrous cam......and the car was faster with the nitrous cam even NA........obviously doesnt always work out that way, but it was an interesting experiment, esspecially since they were very very very close to teh same grind numbers.

install it straight up with a degree wheel. +2 is advance built into the lobes. follow the cam card to install it to the proper specs.
take lift number and divide by 1.7 then multiply by 1.8 to get new lift numbers for 1.8 rockers
PS then grab a lane when it's done

if my math is right the new specs are............
in.237 / ex.243
in.600 / ex.612
if my reading is right, a FI cam is kinda on the same level as a NA cam.. bigger=more converter, correct? So with this cam now being somewhat big, my 3800 converter shouldnt be soooo bad im assuming?

You should NOT spool the turbo while on the brake, that bitch should be spooled before you are on the brake. You will slaughter that trans if on the brake that long, just an fyi. Put some dual rear calipers on the car to help with this.

Incorrect. Rocker arm ratio really only affects lift, not duration. The specs with the rocker arms would be 224/230//600/612//114+2. On FI applications there is no reason to have advance or retard ground into the cam. The +2 will not hurt, but it is not needed. You really need to match the converter to the cams duration as the duration will define where the power will be made in the RPM band. Since the rocker arms do not affect duration, there is no need to change the converter. If you are looking to help spool the turbo, a transbrake would be more effective than a high stall converter.
