On the rockers, any recommended brands/sources for them? He has a good number of wholesale accounts with suppliers.

Thanks again!

You will have to ask if he will still make you a set?  http://www.rmcompetition.com/rocker-arms-.html

Those adjustable rocker arms will come in contact with a stock OEM valve cover as the adjuster hits. A "NON" adjustable rocker arm will be fine.

Sounds like you about have it covered. I was thinking about doing some of this on a 1995 F150 SBF, but I don't like messing with the EFI, especially on a daily driver. Alot of people convert to the Mustang ECM and use the aftermarket support they have, for the SBF. If you are going to fab an upper intake, it would seem there must be some way to overcome the lower intake problem, and use the older heads, are aftermaket ones? Crane may still have the roller rocker guide plate conversion kits, if you need one, they are listed for $140, at Summit I believe. All the old 5.0 tricks should carry over, if you can get the hard parts, for them, to intergrate the system.

There is one major problem in using a Mustang ECM in a Big Block truck, it is spelled E4OD. Only a truck ECM has the needed circuits for that transmission. The F3TZ heads actually have bigger exhaust ports than the carbureted heads, if I go to aftermarket heads with larger exhaust ports, I end up with a "what do I run for exhaust" issue. Anything I use has to clear the truck frame which is actually tighter than you would think on the right side. I am not really a big fan of using headers on a street truck, particularly one that is built for heavy use. My present exhaust is the early EFI manifolds coupled through the 1990 front pipes to where the catalytic converter would be. There is a converter flange with a pair of 2 1/2" pipes all the way to the original 1986 muffler, then a 3" tailpipe over the axle and out the right side behind the dual wheels.

I know what you mean about headers. Some people run th 5 spd. standard transmissions. I did not know that much about the fuelie heads, but I always thought they were flow limited on the exhaust side, compared to the older ones that are ported? This link is interesting. Do you think the Price spacer could be reverse engneered for a upper fuelie intake, and and a old manifold, or is that impossiablehttp://broncozone.com/topic/17735-460-fuel/?

I was trying to remember where I found it, but the late fuelie heads (F3TZ) have bigger intake valves and exhaust ports than any of the others except 429 CJ and Boss heads. If I find it again I will post it, it may have been on Scotty's website.

May want to talk to Boss429 as he has put the EFI intake on D0VE/D3VE heads.

As far as heads, there are no aftermarket heads for the EFI 460, the intake ports are located a bit higher in the heads than the carbureted ones.

Scotty has some;
