He hasn't cut it loose yet. It's in a 68 Plymouth station wagon it's a great combo. Just be careful and don't put too much cam in it for the street . His cam is about .560 lift and around 240 duration, flat tappet hydraulic. From Hughes. Nasty!

Also keep in mind that the addition of the bigger valves does nothing for performance unless the head is ported accordingly. The port will only move so much air, despite the valve size.

RMCHRGR top fuel Joined: Sep 2007 Posts: 1,890 Spahn Ranch	I built one for a friend last year, 438" with a 3.75" crank, 1969 383 block. The rotating assembly and heads were 440 Source. Very mild combo Hughes 228/232 @ .050" hydraulic cam, low deck Performer RPM intake, Holley 750 and small dyno headers. It made around 450 hp and 475 lb. ft of torque and even went to 6,000 rpm. Built to cruise and have good vacuum for power brakes. The dyno headers probably cost a few HP so he went with 1 7/8" TTi headers for when it goes in the car. Not terribly expensive to build. We ran the cost both ways and turned to be only slightly more than a full rebuild with reconditioned, stock-stroke parts.
