I was hoping someone could tell me what needs to be changed to convert a late model 351W HO Roller engine to run a carbie setup.

I know i need manifold, carb and ignition system. I dont want to use the computer. Can i use the same components as older 351W or do i need a different ones?

I have a procomp ignition system for a 351W which was going in a XW engine can i use this one?

Also can anyone suggets the best manifold and carb for this engine. As far as i know its a stock HO engine with no modifications.

Thanks in advance!

Is the engine a factory built engine or rebuilt using late model components? The type of cam will determine what type of gear you need to use on your distributor. Check out this CarCraft article for some good information on this.

For a stock type 351w, depending on your intended usage, I would think a Weiand Accelerator or an Edelbrock Performer would be the go.

Don't go overboard on carb size unless you plan on using the engine for racing. Have a look here for some guidelines on selecting an appropriate model.

What type of car is this engine going in? If the car was originally fuel injected you may need to change the fuel pump/hose setup.

Thanks for the info anakha.

It is a factory roller engine and will be going in a XW falcon so i will be getting new fuel pump and hoses. I will have to give procomp a call to see if i can use the ignition gear i already have. I also need to get the cam specs to pick a matching carb and manifold. Anyone know the specs?

You will need a steel gear on the dissy same as 5.0 roller if using mech advance dissy..I assume its 95 or latter model motor? The 351 has same timing as 5.0 H.O roller so you should be right..Depending on fuel pump? You'll need a low presure pump...

Thanks ebxr8 what pressure fuel pump would you suggest? Its a cobra spec motor from the Mustang or Lightning.

The Lightning was flat tappet BUT I thinkl its still a roller block, you'll know when inlet is taken off...You'll need a low presure pump for carb...
Yea std fuel lines maybe small being low presure....
