It think the speculation should be taken as a compliment for achieving pump gas numbers which seem to have shattered what was perceived as the ceiling for that combination.

The bore prep, rings and piston selection play an equally important role as cam choice- but they don't hold all the secrets to making that kind of power. It really is the entire package. I would love to hear more about it John. Whatever you are willing to open up on is great, but in a post about gauging interest- I'm not expecting free speed secrets. </div></div>

Ok, since as people can see here, some of my &quot;friends&quot; over on YB and Speedtalk give away some info, I will too!

Pistons in our stuff so far has been ONE-OFF with our designs by JE. These motors are NOT cheap, and infact for what there worth, you could probably get more power with different parts. It's just the WAY that one get power and what one is looking for. These are pump-gas friendly, but would run better if we put &quot;race&quot; gas into them. But were doing this to prove that you CAN make power with these motors. This 468 is a Scat rotating assembly with our piston, some details in the short. Wet sump and NO vac pump. Solid roller over 700 and lobes that WILL live on the street and lifter that CAN idle. I &quot;recall&quot; these were 291 '70 heads?? But that I don't recall. There is LOTZ of time into the whole induction package. That goes basically from CRANK to air cleaner on there. Stroke is a given, then we work with rod length and piston comp height. It's a whole package. Even valve took a month to figure out right. It's all work and R&amp;D.


For example, my ZL-1. We just spent 18 hrs fine tuning my &quot;198&quot; intake and got 3+ CFM BUT were are now within 2% from runner to runner on a SF600. My motor WILL make significantly more HP then this 468. Just worried about the block IF it will seal.
