Can I convert from 750 to 950?

[SRT_DSTRHOLC]

I have a feeling I might need more carb (from other suggestions). IS there a way to make my 750 into a 950dp? I have a hp center already the carb is from Biggs.

10.7 compression
cam is 248@ 500 on 107lca
heads flow 276 @ 500 and 286@ 550 RHS heads
360 block

Car is mostly street, but if 750 is fine, Im good with it.

74B,

Based on your application, and a 7000 rpm shift point, the 750 should work very well for you.

Even a race based 360 spinning 7500 rpms requires slightly less than 800 cfm, so IMO the 750 should work great for a car that is primarily street driven.

got 360s...racing..all use 950 holleys...great carb....

the pro form main body is suppose to flow around 830 cfm...

pro form makes a 950 main body..and you will need a new throttle plate too

so basically everything? haha Main plate and new HP main body

I would need to see how they effect the car on the dyno, that way on the street I can run the smaller one and on the track, the bigger.

thank you, I will try both to see which makes the most, just to see and learn

You can use the 750 main body but you need to modify the base plate where the idle feed holes are. Google it.

Only difference between the two carbs is the larger base plate throttle plates. A holley 850 flows way more than a holley 950. If your going to buy everything get a 850, IMO
