I am currently running the following:
302
E7 Powerheads - CNC Ported
Crane 1.6 RR
Camshaft Innovations Custom Cam 520/520 lift
TMoss Ported Upper/Lower Stock Intake
70mm MAF
19's
AOD / Lentech Street Terminator / Edge 3200 Stall
4.10's
I am thinking of going with a small 5-6 psi supercharger (Powerdyne or Novi 1000) or with a set of aluminum heads and intake package. I can only do one or the other and was leaning towards the heads.
I have researched the flow numbers on the Powerheads and some of the popular Aluminum Heads and it seems that the Powerheads flow fairly well which is making me consider the SC instead now.
Here are some numbers I have found. So what will I gain by going to aluminum heads other than the weight savings?
POWERHEADS:
100 64 63
200 123 110
300 175 151
400 204 170
500 217 175
600 N/R
TRICKFLOW STREETHEAT
100 72 48
200 138 78
300 181 100
400 207 125
500 220 135
600 230 140
AFR 165
100 N/R
200 123 118
300 186 153
400 225 178
500 250 185
600 250 191
AFR 185
100 N/R
200 129 118
300 189 153
400 224 178
500 267 185
600 282 191
FRPP GT40X
100 65 52
200 126 105
300 172 145
400 202 149
500 216 149
600 215 149
The AFR 185's make a pretty good jump in the 400 - 500 lift range, but if the cam has 520 lift and through the valve event, spends more time between 300 - 400 lift than at max lift, will it really be worth it?
Not pretending to know anything here, legitimately looking for answers and help understanding.
Thanks.
