371 build W/Big Mouth heads
Nice cam, but as they say...fast don't last.lol
This was considered heavily, but remember I was going for a win in the SPEC smallblock class up against Jon Kaases' 414 Cleveland--It only had to last for about 30-35 dyno pulls total. This will last much longer than that--probably years in a street/strip deal.
Look up his cam specs in his class winning engine, (you'll be amazed, you'd think we spoke about this)I believe had we made it our 414 wearing these heads would have been a top 3 piece-maybe even a 2nd placer.
Getting back to the aggressive profile, I ordered the cam with nitriding, and will also be using EDM lifters, carefully selected Isky dual springs with inners removed for breakin and the valve train also uses hollow stem valves and some super light tool steel retainers. The breakin process is also something I am extremely vigilant with. I use the BreakIn cycle feature on the dyno which totally kicks ***, along with a pan full of Lucas 30 wt or Ammsoil 30 wt Break in oil. I am very good at setting timing (very advanced is always way better than retarded) with my trusty LeanBurn distributor and I also use a carb that I know and trust. A lot of guys under-estimate just how much fuel or pumps of fuel it takes to start a new , never fired engine as well--its a lot more than you think. This one will fire in 1-2 revolutions like all the rest. Now with all that being said sometimes **** happens-I hope this isn't one of those times. J.Rob
