408 horse power?

Hopefully you can read this:

I run the appx. same year head (ported) also with a 2.02 valve so I've used my flow figures and pumped them into Dyno 2000,

I included the 408 cui, 750 cfm carb and your cam specs.

I assumed a DP intake and small tube headers,

In my experience, the small tube headers/open exhaust works to be about what you should expect set of TriYs through open pipes prto produce in real life


Flow figures used were:

.100 - 75
.200 - 142
.300 – 170
.350 - 195
.400 - 219
.450 - 231
.500 - 240
.550 - 243

.100 - 55
.200 - 114
.300 - 130
.350 - 140
.400 - 142
.450 - 145
.500 - 148
