runs cool actually and i have the ac delcos that i ran in my gt40 heads they were fine..

The recommended plug for the Edelbrocks is an Autolite 3924. I'm sure what the series the Delco's are but I assume they are incorrect for the Edelbrock head if they were in GT-40 heads. The plugseatis different if I remember correctly.

what happends if i have a bad valve??? ok so the car feels alot more powerfull but no so much at around 2000 as like 2600 i was thinking maybe because i ahve 3:08s in the rear and when i put the 373s in it will fix the power range

ok so i lied the plugs are accel's lol

Still might not be the right seat type. Replace them with Autolite #3924. BTW, Accel plugs are junk!

haah yea o yea before i realized the number 7 wire wasnt alll the way on the distributor...it was arking out the otherday so i replaced it but my dad must have not snapped it down all the way and the plus i pulled out ( number 5) looked fine

You have not described anything about this build. Heads, new used, performer, RPM, or other? If they are new I would sure hope there isn't a bad valve. Used, Didn't you inspect them. As for the power at that rpm, hard to say not knowing what other parts you are dealing with. One thing does come to mind though, did you measure for proper pushrod length and correct rocker geometry.

ok the heads were bought from a guy who never used themm...dad inspected them and did the valve adjsutment( setting to 0 lash) heads have porting and valve job by hbr performance...they are edelbrock performer rpms i belive my dad said...if theres a bad valve whats that mean lol

PJC Racing

Ok your working with stud mount (RPM's), did you measure for correct pushrod length and rocker geometry? 0 lash, did you preload the lifter? Bad valve, dead cylinder. But if they were inspected how would you have a bad valve. How were they inspected? Were they taken apart andhad everything measured?

yes pre-load was set....il pull plugs out to see if i have a dead cylinder.. thats why im saying i dont think i have a bad valve...i think my timings off...
