A member in another thread made a good point that I never really noticed before, why is my car only gaining approximately 9-10mph after the 1/8 on spray(150 shot), when NA it's gaining nearly 20-21mph??? The car feels silky smooth with no misses or pings or anything, could something be wrong or do my times seem on par with other LT1's with similar mods/spray? Just curious, any info appreciated. Thanks.

I'm gaining 24 mph in the last 1/8 on the bottle. You sure you arent blowing out the sprak? have you tried jetting it down to see whats going on?What are you running for an ignition setup? plugs/wires etc?

 

I'm running an MSD-6AL ignition with autolite 104 plugs, I think the wires are taylor. I wonder what's up??? Like I stated before, the car feels to be making good power, but obviously something just isnt right. I havent had a chance to try out the different jets, the nearest 1/4 mile track from me is a 2 hr drive, so I wanted to see what it would do full-tilt, plus I didnt want to abuse it by making numerous runs because I had to drive it home. Any suggestions??? The car is obviously not a dog with being able to nudge into the 11's, but it's definately got more potential. Thanks.

when i was heads/cam/150 shot i was picking up 26mph ...

 

I picked up 28mph in the last 660'ft. on the squeeze.
I pick up 24mph in the last 660'ft. on Horsepower.

 

Wait just a second, I just did some simple math only to figure out that my car is gaining 20-22mph in the last 660ft. Still not as good as your numbers, but not bad to be untuned and no timing retard. Sorry about even posting this!! Thanks.
