Building Drag Truck

the you tube is the example I want to build it like.

My truck is getting cut down and new frame put under it.

I have a Dana 70 Im using,Tranny I want a 5 speed

motor is a 451 RB Bill Miller pistons 10.3 comp,forged steel crank redone rods

roller chain but want to use gear drive for cam ,71 block redone 225lbs bare,

As soon as I figure what RPM I want it to live at Ill figure the cam.

main webbing brace Im thinking to go with.STEALTH heads 440

Soon as my Stealth is done Im selling it for money to build the rest.

My cab on the truck has zero rust but the frame is crappy.

Why a Dana 70? Not only is it heavier than a 60, it's over kill and robs more power. On the 451, I've heard of that based on a 400 block using a 440 crank. The 400 block is more compact and is cast with more strength than the RB block is and the main web is quite a bit stronger than the RB. Also, since the cylinder walls are shorter, they are more stable than the 440's cylinder wall. The 400 has larger bores too which helps to unshroud the valves more than the 440 will. On the gear drive...those transmit a lot crankshaft harmonics in the valve train and that's the last thing you want to do. A chain is better but a belt drive is even better but those are pretty costly.

Well the Dana I own already and that cut costs but it has full floating axles

and will take what im going to do,your right the Inertia load is alot but its

strong,a beast.

My 451 is a bored out 440 RB block 1971 bored out to 4.375 all steel nothing

cast.A 400 B block has a bore of 4.34 as stock ,the 72 blocks were the best of

them.The 400 B block internals are lighter than a 440 and shorter connecting

rods and pistons but you can buy what ever arrangement's you want.

The heads on the 440 wedge with its big bore unshroud the valves also,

the draw back is the oil system,Mildon is the way to go.

I need the timing system to be rock solid ,but depends on the cam I choose.
