Ideal HyperPak setup???

I have some experience with the Dutra Hyper Pack. And Dutra dual exhaust/split manifolds.

I built a 9.5:1 compression '73 225 slant six for a friend using the Hyper Pack.
The cam is the old MP 268 dur-.460" solid cam, MP windage tray, RAS roller rockers at 1.55 ratio, '77 taper seat plug head milled .090" and fitted with 1.72" and 1.50" s/s 1 pc valves, 340 valve springs, moly retainers and machined locks.
Heads are 44 cc's.

The intake does have an adapter with a divider plate and an 800 cfm ThermoQuad carb I built and jetted to the engine specs.

Trans is a 904 with Turbo Action reverse man valve body and a 2,200 stall converter. Rear is an 8.25 with 3.23 gears.

The car is fun to drive and has excellent road manners and nice idle too.
But the intake acts more like a typical single plane intake(which it is)and is hard to get good even fuel distribution. Would be a good idea to do the mods suggested in the MP engine book to the plenum floor near the beginning of the runners.

There is a lot of jetting and tuning to be done but the eye-candy factor is topps, David.
