Intro to a port job
Still testing the nitro's on the exh.
They are 4cfm better than your edelbrock exh so far. The intake numbers
.100 65
.200 132
.300 192
.400 245
@.450 258, they all do between 254-259*
.500 263
.550 262
Each head has one that does 267/
[email protected]=4 cfm better than some n only 3cfm better on most. If you stand close to the radius...it does 271cfm lol. Smog heads, funny.
I'm trying to get the exhaust numbers up a hair atm, tomorrow it continues.
