I'm feeling like the post got side tracked by some dislike for Bill and some people's opinions on the cam. It may be a little big for the combo. But, from what's been said the car went faster with this cam before the head change. Also, you can just look at the ET difference of .18 from a lowly (junk)455 compared to this 505. Without seeing the mph difference between the 2. The 455 is doing with converter and gearing, the 505 probably would have benefitted from more converter and shown a much better ET. But that's just speculation. The HP difference from 6.80s-6.90s at 98 mph to 6.70s at 102 ( guessing at the mph values) is significant.
Just my .02 |

Back to Mike's car, what converter is in it? Maybe too tight for what the motor wants.

I had to ask the guy four times who a gentleman is that Bill implied was intelligent. I recieved three responses before one answered my question. That is why the thread went sideways. Dcar had the same issue in regards to the camshaft being used. Bill initially implied a smart guy by the name of Kevin Sweeney selected the cam and then labeled D'car as a CV1 hater and he should be censored also. One must abide by Bill's wisdom because he knows all and is never wrong. I personally feel the cam leaves a lot on the table but explained why Kevin Swaney may have thought it would be a good choice. In the spirit of this thread I will ask a question, hopefully I am not labeled a CV1 hater and am not censored but it is something related to the "back to back" results: If it took more than four years from the time the Hi-ports were run and the current passes with the same combination..... We're the tires the same one used previously? |

OK, I will start here with you this morning. How fast have you ever been down the track and how many passes have you made with a 1.1292 60 FOOTS ! ??
I have been down the track way over 1000 times and the best 60' I have ever had was a 1.42 and let me tell you, you are stuck to the seat and can't keep your left foot fully planted on the floorboard. All your pressure is on the gas pedal, its really fun. If you are a drag racer, especially if you build everything on the car yourself like me and you see a 1.1292 60 foot in a door car your years get kinda big. I imagine your eyes might get blurry for a split second, wheels up and looking at air, kind of violent. Do you know how hard that is ? How much effort that takes ? I posted that because you were implying Paul was a "hater" when in fact he was involved with a very impressive CV-1 car . Did you look at that thread ? Did you see all the "nice job" comments and noticed the stature of some of those posters ? Best of the Pontiac best many on them. Its not a 6 second car like Mikes, its not even a 5 second car. Its a freaking stock block car running 4s. A little 4.155 bore short block a lot like the one I just put together. Being impressive makes nothing but sense. Also tells me that canted valve helps out that small bore. |

Can not wait to hear you reasoning when it can not run 137 MPH in the 1/4 when this one does it in the 1/8. Stan

Maybe he is in the upper 10%, I don't know. IQ has little to do with this when all anyone needs to do is punch numbers into a free program and you will get close. IMO Mikes car went faster in large part because that cam was too big for the top end. Those things are not really a 380cfm head. @ 1" they could not get 380cfm. Like I said, more like a 350cfm head with any kind of cam a sane person is going to use. Anyone who runs a 1" lift cam has far better heads than those High Ports or your CV-1s in those configurations. That pedestrian 60' with the high trap speed tells you a lot. And just because his car ran faster does not mean any head is better than the other. Combo was off. Do I think he could run a better than a 1.45 60" with a 6.45 with the right combo running E heads, High Ports or CV-1s, yes. It does not really matter. |

… simple as a free program huh ? Ok, use your free program and tell me what the cam looks like to make an 828ci ProStock combo with 720cfm heads, 2.750 intake valve, and 16 to 1+ compression make well over 2000hp NA ??? … … and about the flow testing, by your words are you calling me a liar ?? Regardless of what the 380HP head flows on a smaller bore the 378cfm shown is exactly what they flowed on a 4.375 bore, an that’s a fact … … and now you’re saying Mike’s results are not valid or real meaning the CV-1’s he’s using are not any better than the heads they replaced because the combo is “off” ?? … but yet it pick up 3 tenths in the 1/8th after the new heads ?? … you have to see how ridiculous you sound right ?? You can’t be that blind, I refuse to believe that, bias yes but not blind to it, that’s just crazy talk … … do I think a set of standard pushrod Eheads ported or not out run Mike’s CV-1’s in his car ?? No I do not … … and you’re wrong, it actually matters a lot … |

… have I ever been down the track in really fast cars yes I have, a lot actually, apparently well faster than you, but again that doesn’t make any sense here, I design cylinder heads and manifolds primarily, funny how you seem to just gloss over the topic of port dynamics like actual shaping technique or sizing percentages or even flow bench testing, I bet you couldn’t run an SF1020 if your life depended on it 👍🏻 … … but yet here you are, trying to talk down to me like always … |

Hey ask your ex-con buddy Byron why he is disrespecting another guys Pontiac efforts. According to the chicken-chit coward no one is supposed to do that. Let him know he has my permission to use this picture for his FB page and make a post on "How to be a hypocrite" |

What it has to do with is Paul was involved with a very impressive CV build and deserves the credit for doing a fine job and not being a CV-1 hater. No one hates you Bill, I wish the best for you. |

the question ? ,,,The cam is too big, so I said it. There are Wide Port pump gas 505s with over 850 HP around with cams that have 20 deg less duration. ,,, I do not know much about Pro Stock mountain motors. You know more about ports than I do OK. Me talking about those KRE heads have nothing to do with you. I have never been impressed by their CNC stuff. That is what I was trying to say. ...Mikes results are real. ....std pushrod E heads are not a fair compassion to CV-1s. Non cookie cutter Wide Ports are. ...I have never tried to run a flow bench. But you are a human being and learned how to do it. Same applies for me. |
