While at it flow tested a Torker II as cast bolted to these heads before and after port work.

The Torker with about a .550 lift cam and good exhaust should be able to make peak power
514 HP @ 5300 RPM with 400 cu in engine
500 HP @ 5600 RPM with 383 cu in engine

Re: Making a torker II work
Intake manifold air flow will mean almost nothing here as to producing flywheel torque with a full exhaust system.turbo2256b wrote:_Intake flow_______/_______ Exhaust flow

Re: Making a torker II work
eXHAUST IS THE EASY PART COMPARED TO THE OLD DAYS WHEN THE ONLY GOOD mufflers were hemi and corvair turbo mufflers when I REALY needed 3" exhaust.
Re: Making a torker II work
Slightly off topic, but it should still fit in here.
I remember years ago, Holley sold a single plane that had like a 45 degree funnel around the top of the plenum that sorta choked it down to a square entry-way.
BUT after a bit of rework, it seemed to run fine to very well!
What intake was this?
Or was it the Weiand single plane intake that Mr. V. worked over?

Some Street Dominator single plane intakes are made that way like the one for the 351C.pdq67 wrote:Slightly off topic, but it should still fit in here.
