Thermoquad issue

The 800 = small & the 850 = big acceptance rating isn’t exactly accurate. In short, according to our departed member,
small = 737, big = 787, small race unit = 800, big race unit = 915.

Carter Thermoquads ~ 'More General Information'

Holley and Carter used 2 different specs on the flow bench.

For sake of NOT confusing everyone....1.38 is 800 and 1.5 is 850....AS PER CARTER.

Your #'s are IF it was rated on Holley spec's
