Re: Anyone running a Comp Magnum 292...
My firend had the comp 292 cam in a 70 ss396(402) with holley 750 dbl pump and Edel trq al intake,headers,stock 290 heads,crane varable dur lifters, 331 12bolt posi ,with m21 close ratio muncie.
I had the car tuend/dialed in well and with the varialbe dur lifters blleding off a few deg dur 2 low speed the motor/car was very streetable.
He could be in stop & go traffic for a while and then get into it and it would run very strong to approx 6200-6300 rpms.
Even with the var dur lifters it had only 8 inch vac @ 950-1k rpm idle that sounded hot/ratty and you definately knew something was under the hood.
But i was surprised the power brakes worked ok at low speeds but maybe it had something to do with the master & booster being newly restored.
But the brakes felt a little hard at idle but stoped ok and other than that they were fine.
If you dont run var dur lifters that cam will idle very doyugh in a 402 so keep that in mind.
But if you use variable dur lifters to tame the low speed duration some and have the expertise to dial in the carb & timing for the 292 cam it can work fine on the steet as my friends car did.
Since the muscle cars are getting worth so much my friend asked me to cam it down and reinstall the stock intake and q-jet which i did.
The cam and lifters have approx 3500-4k miles on them and the lifters were kept in order to keep correct lifter woth each cam lobe that it was broken in on.
As a matter of fact i think he still has the carb and intake too which was removed a couple months back with the cam & lifters which he wants to sell . The same parts new (cam/lifters/al intake/750 holley dbl pump) would be approx $850-$900 and i bet he would sell the pakage as a matched working unit for less than half of that so pop me an email if interestsed.
