Headers and a good free flowing exhaust with X pipe or minimum H pipe will pump it up a lot. On your combo the exhaust valves are a little too big and the cam is a tad small for the heads and an RPM performer is a better choice but yea got what yes got. what is the gears tranny and torque convereter. A 3310 750 vac would be a good crab unless it's 4 speed then a 750 DP.

sorry, the valve sizes were 2.14 / 1.81
the pipes on back would be 2-1/2 , unless 3" would be considered a gain, but maybe not with manifold exit i.d. or collector size
would do at least a H-pipe
1800 stall, 3.23 on the drive train
thanks for the help
that stall and gear are gonna kill ya.

I just installed a six pack Eddy head in a 69 GTX today--TTI 1 3/4 inch fit like a DREAM! Power steering and all--The bigger tubes are really for the big HP--I love the 1 3/4 for STREET stuff

Went 12s with a 440 and a .455 lift cam and compression bent exhaust.
Plus, you can put more into the motor when you don't have to buy a gear, a torque converter, and tires.
