Well so it was time to break another record for stock block LS. Stock bottom end, ported head with our regrind cams, 20G with ebay tubular manifold @21 PSI on Q16.

wish is had rods bolts so I could have revved it higher

Nice Should be fun to drive check your pm's Chris

I have a set of D-series ARP bolts... not sure if they are the same....

Impressive What boost is that at? In a CRX that would be awesome! Y49 as well mmmm When you say 20g is that an upgraded version of a Subaru/Mitsubishi 16g? I have a 10.5mm Evo6 16g with a tigart manifold going on my B18c & I've been looking at the 20g cold side upgrade they list it rated to 450hp on a Evo... Bill

Damn, I didn't know a 20g could make that kind of power on these cars! Good Job Chris!

Serious....serious...power .. go BUGERMASS!!!

Its mainly the cams that make it possible. The original shop that I worked for back in like 1999-2000, went through about 4 revisions of the these cams before we found a profile that we loved. Back then it was for all motor, but one day I decided to throw them in a boosted motor and i was like holy hell!!.. They are just plain a great all around cam for an LS. I'm thinking of having crower or webb or somone make them on a production level for us. They have tons of lift, tons of duration, but the actual profile is very gentle on the valvetrain, I've run these to 8K on stock springs and retainers with no issues, and on a built head will make power to 9200-9400 or so without poping out rockers.

How are they in comparison to say the 404s?

not to be mean, but 404s are garbage .. Yes ppl make power on them , but they are really crappy compared to these and make significantly less power than my regrinds. I can run my regrinds on stock spring and retainers to about 7800RPM safely. and they have way more lift and duration than 404s.. They just have a much gentler ramp in/out .. Designed by a real cam engineer. lol.

Wow very impressive numbers on a stock LS.

Mind sharing your cam engineer?? If not, i understand but Myself, rocket and donf do use the same grinder, and he is very well known, i love this, i've spread this link to a few forums just to show what ectune can do.. Again, Great buger.. looks euper nice.
