Missed on this combo?
Man, you guys are great! I'm learning so much just from this post....and YR, I cant thank you enough for the offer. I may even take you up on it. I have some things here to address. Going to be a bit long and picture heavy, but i'll try to be straight to the point.
1. the issue of my lift at the valve. Well if you remember I came up with .626 at the retainer. Supposed to be .668 per cam card. I know about geometry loss and all that BUT....got home from work and decided to measure the lift on my "in car" engine.
The cam is a Lunati showing .640/.640 on the card. You can see in the 2 pics I came up with .623 and .618. Add the 0.14 lash and you come up with .637 and .633. You can see the indicator for yourself. Remember you're reading it backwards from zero. I did it 2 different ways. So......the fact is my Lunati with .400 lobe lift and 1.6 rockers came up very close to the card specs for "valve lift"(.640). Within .007.
And the Bullet with .4176 lobe lift and 1.6 rockers came way short at .626. .042 thousands short. Thats a lot of lift to lose compared to .007. So either cam is off or rockers aren't right. Which is off is anyone's guess. But something ain't right.
Next issue, my dyno guy calls me AT WORK today, on Sunday cause it's buggin' him too. He asked if I remember which pipes we had running out the wall. He said we might have used some 8 inchers that he was using to dyno some blown alcohol thing earlier in the week. He usually runs a 4 inch pipe from the header through the wall. Said if we did, that may have a LOT to do with the numbers. Especially torque.
I happen to take a couple pics that day and sure as hell those pipes don't look like 4 inchers coming off the header. Can that really make much difference?
Last, I posted a couple crappy pics of an exhaust port. Don't know if you guys can evaluate the porting or not. Hard to get a good view with my camera.
Well, thats all I got for now. Don't know whether to call Hughes or Bullet tomorrow. Personally from my measuring at the pushrod......I am pretty sure the cam is not right.
Maybe all I need is a proper cam and smaller pipes on my next trip to the dyno?
