My buddy has a 512/516 custom cam he took out of his mustang that ran like 8.40s in the 8th pretty much a stock stang on street tires with headers and a few other bolt ons and changed the cam out to a different one and put nitrous on it he said he'd sale it to me for about 75$ he said it went 8.40s on motor and he switched it out to another cam and it slowed it down to 8.60s on the same tires all motor. he says it ran strong in his car (which i rode in it and its quick as **** for a pretty much stock coupe. my question is can I run it in my stock 90 5.0? I was going to buy a Bcam and a few other things but I'm kinda on a small budget right now and I got it all tore apart and figred I might as well stick a cam in it, so what do yall think? worth it and would it be ok to run in my cam untill i get ready to do a complete h/c/i swap in the summer?
