I wanted to get an idea what I might expect from the following setup.
ported and polished D3ve heads with 2.19 stainless intake valve,1.76 stainless exhaust valve, upgraded springs to match cam, bronze valve guides
roller rockers 1.8 ratio with 7/16 studs, guide plates, stud girdles, and 3/8" pushrods
solid roller cam 232 intake and 240 exhaust duration .608" intake lift .63" exhaust lift 112 degree lobe separation 107 degree intake centerline
torker II intake
850cfm carb
2" primary 3-1/2" collector headers with 3-1/2" racing muffler exhaust
10.8:1 compression using domed forged pistons at zero deck
H-beam chromemoly rods
Main stud girdle
I think thats the most of the main things.
This will be run through a beefed up c-6 with a 2500 stall convetor and in a 4x4 f-150.
Should I change anything or do something more? What can I expect for horsepower and torque? What should I expect for idle quality and vacuum? Is it worth going to needle style bearings for the cam?
just like to hear some ideas from guys that have dealt with this motor. I have run 400's in the past and this is my first 460 build. Would like to do it right, to the best I can.
Thanks Everyone
232and 240 duration that conver WILL be tight should run around a 10 inch 3500stall.if memory serves me rite 385's used a 1.72 ratio rocker with 1.8's youll have to check for coil bind on your valve springs. i know on a small block goin up .1 will give ya around .030 more lift probably close to that on a bb
i always try to get at least 300-400 rpm stall than what the cams bottom rpm range is.you may be able to get away with that converter but it might be a little soggy on the bottom.
Thanks for the replies. The motor is at the machine shop now. I went with a custom converter that should stall around 3200. I also got custom forged pistons that will give me 11:1 not 10.8:1. I hope to have it in the truck within a month.
What do you plan tp do with the truck. If it is going to see serious street duty you might want to rethink the compression. Hi octane gas aint cheap and you could need better than 94 octane to avoid detonation and run on. I would consider no more than 10:1. If it is going to be an off road racing truck, go wild and feed it the best stuff.
It sees very little street use. Main purpose is offroad racing. Plus 110 is $4.85 a gallon. I have two cars, another truck, and a motorcyle. So I never put very many miles on any one vehicle. My other truck is a 97 f-250 extended cab 4x4 also modified that only gets 7 miles to the gallon. Gas stations love me but i wouldnt have my truck any other way.
