CNC'd LT4 head flow numbers inside.
The heads were completed yesterday. I had them flowed at lunch today by a friend.
4.030 bore on a Superflow 1020 bench.
The heads have Manley 2.02 intake valves and 1.60 exhaust valves.
All cylinders we within 5-6 cfm of each other..
Intake Exhaust
.200 143 110
.300 207 147
.350 232 163
.400 253 178
.450 270 187
.500 282 194
.550 285 201
.600 286 206
.650 288 210
From what ive seen i have a monster set of heads. Which is why my car has alawys been so strong with a measly HOTCAM.
4.030 Bore
4.00 Stroke
408 cid
With the head flow numbers and my engine size anyone wanna recomend a Cam?
