.578/.585 lift w/1.5 rocker
110 lsa/ 106 icl
advertised dur 273/279

Curious if this cam is a good choice or should i change anything with it. Thanks

Not sure what gear you are going to run, but that cam will run out of steam well before 7000. My guess is it is going to have it tongue hanging out at 6500.

sorry forgot, gear is 4.10, 26" tire. Current 350 crosses traps at 6000, but iknow this is going to be different motor combo. Wanted to keep engine around 6500 rpm shift point.

I am thinking you'll be running out of steam early with that gear, and the tire.

This build going to see any street at all? If so you may consider a 112°-114° lobe sepperation.

While you're wanting to keep the shift point to around 6500 what trap rpm are you expecting?

I think you may be ok with this cam if you're wanting to limit to 6500 RPMs.

yes it will see street time, strip time about 3 times a year for fun. But it doesnt need perfect street manors, it only gets driven on weekend and not for that long of trips, just around local cruises and such. This is the other cam I am considering, and i do want to keep engine around 6500 rpm shift and trap speed, give or take alittle.

Advertised Duration (Int/Exh): 279/285
Duration @ .050 (Int/Exh): 249/255
Gross Valve Lift (Int/Exh): .585/.600
LSA/ICL: 110/106
Valve Lash (Int/Exh): 016/016
RPM Range: 2800-7200

This is a lunati cam as well. Thanks for input.

Same,...but would still like to see the lobes a bit farther apart for the street.
