Default No top end mph

I took the 1050 Holley and restrictor plate off and replaced with an 850 Holley. I lost finish line mph. 60;s are 1.33 with an 1/8 of 6.30/107 but only manage 9.9 barely breaking 132mph . Do you think it's the carb being small or should I look at a gear change? Car never had high mph even with the 1050.
I have a 4.10 gear and 30" tire. Shift at 6400 and cross the line at 6800.

I run a 10.00 index and am tired of having the lowest mph. I am always looking behind me to see where they are. Would like to be around 135mph.

Only ran it all out thru the 1/8 once with the 1050 and ran a 6.04/111 with a 1.29 60'. Didn't have enough gear to run it thru the 1/4.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
