On part throttle The cars seems to pull harder than at full throttle

I can feel the car fall on its face alittle when I hammer it and the exhaust note gets smoother and quietier ?

Car runs not so good at that timing 18 seems the best

And yes I got the whole trick flow top end kit cam heads lower and upper intake and rockers

I had the timing at 10 11 12 13 14 15 16 17 already no luck

18 is the best

Maybe its running rich at wot ?

Any black smoke out the tailpipes at WOT??

 

[93lxdm78]

No not that I noticed

Reason I ask is that black smoke billowing from the tailpipes is usually indicative of an overly rich condition. Did you plug your spout connector back in when you last timed the car?

My mass is set up for my 30lb injectors

Other than the feeling the car falls on it's face at WOT, does the car run okay, just driving around say? Any dyno tuners in your area? May be worth a trip to get it lined out. Coud be running lean at WOT as well. Have you played with the fuel pressure any to see if it wants more or less fuel?

Yeah, it could be lean enough to rob power, yet not so much it detonates.
