Again you brought his car into this discussion not me.

Again, there is more to a race car than the heads. A bad converter alone could do what you describe. Why do you assume it was the heads? If the engine MADE 150 hp more, it sure sounds like it was something else. This is amazing to me. Is there a 101 class for racing here? Sure seems like some folks need to start back at the beginning.

I never once said it had to do with the heads. Please point out where i said it did??
If you're going to use a car for an example wouldn't you choose one that is sorted out??
Agian i didn't bring his car into this Bill did. I personally would select a car that didn't have issues and backed up the dyno numbers to bolster my argument, wouldn't you?

#1...you ACT like it has something to do with the heads. Especially since the context is a change to CV-1 heads

#2...he's used various examples, from ones that are still sorting themselves out to ones that are. A 150 hp increase is an increase. If the car only gained a little in ET and mph its pretty obvious to consider looking beyond the heads.

#3...Yes, Bill brought the car up. A 150 hp increase by bolting on a set of heads is pretty impressive. Period. If the car isnt sorted yet...well again, its the car not the heads most likely.

I really think you like this argument enough that you are willing to ignore what others see. MOST people would be pretty happy with such a gain. But I guess you wouldn't be.

... the word political comes to mind here ... it's more a matter of who does it now, than what does it now ...

Sorry i don't blindly believe dyno sheets. I question everything. Ive been on the dyno A LOT enough to know to question things.

... exactly, making a change to a larger CSA cylinder will often times comes with many changes needed to get all of the power to the ground, but most would already know this ...

... doe's one really think that a change to something with near this level of CSA (see pic below) that the car will not require changes to fully realize it's potential ?????? ...

... wake up people, wake up ... leech has tried to tell you guys over and over but most don't listen ... CSA changes everything ...

Im running exact same converter, exact same gear as i did when i made 150hp less horsepower. Zero changes and car picked up .5+ and 10mph. Maybe we did something wrong when we gained the 150hp??

... how much CSA at the entry, at the 2nd choke point, at the apex, and at the convergence point in the bowl are you running, and what size valve are you running ??? ...

Once again you miss the point. IF your converter were slipping.....YOUR converter that is....you might not have gained .5 and 10 mph. But I guess you would have blamed it on the heads.

If my converter was slipping that bad i would know it and have it fixed.

Sorry to give that impression, maybe its the heads maybe it's something else, i don't know. But i do know i wouldn't be using a car with issues to back up an argument.

You've made my point.
I changed from a street convertor to a race convertor changed launch technique a shock adjustment and gained 4mph and over .4 drop in ET.

NEVER changed anything motor related...
At the time I wasnt ready to buy a race convertor but someone's divorce created a deal I couldn't pass on. I hadn't changed because I drove on the street most anywhere. Later found the 8" worked better on the street than my street convertor. Surprised me.
