now with that said I ran the car a few times trying diff. things with know changes in mph or 60'

I have changed the intake to a m1 and 850 custom carb
I changed the cam to a hughes 5964 I think it was
moved timeing 32/34/36
8'' verta
15/8 headers
I went to ss springs no snubber
as I said the car runs good after about 3000/3500
7.70 @89.9 mph with a 1.77 60'
I know that if I can get the car to leave better it will be better up top and all the way around....I think the car should atlease 60 in the 1.5/1.6 range atlease..now I have vid the car it does not spin.....now let me say this also that was find when I took the motor down and the bores where cone shaped about 2/5 thou diff. from top to bottom....and the chain had a little more slack init than I think it should have ...I plan to put a ten. on it this time..but I want to make it a little better than before if possible while it down instead of doing it after it's togeather....save some cash..........I am thinking of going somewhere else and have my heads flowed again..(why the shop stop flowing them at 500 for some reason) anyway thats about it..... give me your thoughts as to what you see or would change on this ....I may go to a 2 plane intake this time not to sure...
