My correct flow #s vs Stock vs TEA vs AFR 185

[White90GT]

I made a little chart that compares flow numbers between my heads that Pat and I ported, Stock TFS (the current model, mine are the older ones), Total Engine Airflows 185 package, and AFR 185 heads.

My numbers aren't as good as I initially thought. The 227 exh flow was at .700 lift, not .600. They were flowed at 25" water, but the numbers are the conversion to 28" water. They were also flowed using a 1 3/4" exhaust tube (same as my headers).
I still beat the AFR 185 heads that so many guys are running on 347s that making 400 at the wheels with minimum exh work.

Model Port .200 .300 .400 .500 .600
Stock TFS Intake 141 205 233 251 251
Stock TFS Exhaust 107 144 171 187 193
Foreman Intake 138 212 251 274 281
Foreman Exhaust 108 144 168 190 215
TEA Intake 142 215 259 287 300
TEA Exhaust 114 152 189 220 234
AFR Intake 129 189 234 267 277
AFR Exhaust 118 153 178 185 191

those cars making 400 with a 5spd or auto? Just something to think about.

#'s look nice tho :naughty:

Flow numbers dont look bad, but remember its not always about what they flow, it also has alot to do about port velocity and how everything is matched up through the whole intake port (meaning from the intake all the way through the head.) Good luck with the new 347 your building. Will be interesting to see how it compares to my 306.

Not a lot has been done with the runners from stock form. I polished them a little myself and smoothed out the radius going to the valve (floor). I think we picked up the most with the work that Pat did around the valve seats in the chamber.

There are a couple automatic 347s putting down right at 400, and many standards putting down around 420.
