Poor guys, you can get 3-4 dyno pulls down here for under $100
with A/F its right at $100

i thought you would have made more hp than that. try going custom grind camshaft. hopefully that will give you that boost over 400.

It is custom grind. The guy i bought heads from had them ported but he believe's the springs are stock. My lift with 1.7 rr is 625/661. Stock springs are not going to handle it. That is why i at 6k i lose power and float the valves. Do's anyone have any suggestions for springs that will handle the cam. I cant find my cam card. I have the grind number's somewhere, if ican find them i will call cam maker and see what he reccomends. If not though, i would appreciate some idea's.

black did you take my advice?

you can call manley or comp tell them that you need a good spring for a soild roller you need a good open press spring like 550 580

right but as far as i learned it's not actually a percent that is lost. it doesn't make sense that just b/c the car is making more power than the drivetrain would use more, it would always use the same amount regardless of power being made. no? Stock my drivetrain used roughly 30hp, why would it use mor than that now that i'm making more? doesn't make sense.

WhiteWindsor

Yes i did. Waiting for a response.

Thanks jasper
