Blower cam wtihout blower?

I'm in the process of building the 71 in my sig. My question is will the car run ok, basically between dyno and exhaust shops (both within 4 mi.'s) without the blower installled and possibly on a couple "fun runs." Common sense says it'll start up but will it be so sluggish that it would turn a "fun run" into a "bum run."

Just wondering because I could potentially run into a few issues with my procharger mounting and installation and I dont want my car to be in operable this summer if i have issues with clearance in the installation.

Up to this point i only have seen pics of one second gen. Camaro ls1/charged
so I'm just comparin pics taking measurments and working with trial and error.

it should be fine, the big diff is in the tune up, not the cam

No problem at all. The high LSA usually attributed to a "blower cam" just raises dynamic compression which will make the car more streetable.

All things equal a higher LSA will lower not raise dynamic compression.

A higher LSA # increases dynamic compression as it reduces over lap. Maybe you're thinking duration.

I was playing with this DCR calculator http://www.alantripp.com/VE%20calcul...okup%20LS2.xls
When I lower the LSA input say from 114 to 112 the dynamic compression raises. More duration lowers your DCR and thats one of the reasons bigger cams require higher static compression to work better especially in the lower rpms. Am I missing something?
