This doesn’t make sense? Why would he launch that car at 7000 or whatever he’s shifting at,if that’s the case that conv is wrong for that combo

Hopefully Bill will clarify this. But I took this to mean that the launch and shift RPM for the CV1s was the same as for the KRE HPs, not that the launch and shift RPM were the same as each other. Stan

I was glad to see you put “In his car” at the end of that statement. There are quite a few standard port E-heads out there running faster than either set of heads he has had on the engine in his car. My little 328 cfm E-heads on my 459” stock block engine were 1/2 a second faster, than his CV-1’s on a 505. Yes I weighed less (3275), but not a 1/2 second less, and not on pump gas, but had 46 less cubic inches. My 350 cfm standard port heads are faster than the little 328s….. Now that I think about it my Dad’s 74 with a 455 and 305 E-heads and flat tappet hydraulic cam went 6.68. It’s not faster than the CV1’s but about the same as the Highports with a big solid roller. You wouldn’t think a standard port E-head would be able to run with either of these heads but they do. I know a ported standard port E-head can be faster….just not on this engine with the parts that were picked for it.

That is impressive. We have a similar combo that runs 5.0's with a shot of nitrous. |

462 with cast iron HO heads, 3680lbs, working AC, 10" tire, .517 roller cam...6.66@104mph in 1991...
With modern converter technology, and modern slick compounds, it would run low 6.50s... |
