Alright, I've been searching and looking over the forums for a while, and I've compiled a list of things I'd like to do to my 95' 351W. I have a couple of questions to ask, and would like to get at least a little more info about a few things.
First, is my 95 351W a roller motor..? What does this mean? Roller lifters? Hydraulic roller lifters? What type of cam and lifters would I have to buy? A Hydraulic roller? Hydraulic flat tappet? I don't want to buy the wrong kind...
Second, the cam itself...I've been looking at the Crane 444232, but the Lunati 11000LK looks to be promising. I'm looking for something with a Nice idle to where I start it, and you know it's got a cam in it. I know with the SD I'm limited, and when I get a MAF conversion, I'll upgrade, but that I know won't be for a while so basically, I'd like to know whats the biggest cam I can use with the SD set up..? Conaski!!!
Third, GT40 Heads...Yes? No? Don't worry about it? Will it work with the cam and SD? What about keeping the stock heads, and adding 1.7 RR? Would I need new valve springs? push rods?
Lastly, Headers...I'd like to get a nice pair of LT Headers, Would Hedman Headers work good? What about Flowtech? Hookers? Ideas? I don't have to deal with emissions here in OK so the EGR and such is really not a concern to me. As is It's not hooked up cause I don't have my tube..
All in all, I'd like to know what all I can do to my 351W SD..Cam, RR, Headers, Heads?
Anyways All help and advice is GREATLY appreciated!!!
Thanks in advance
Also What about the E303 Cam from Ford Racing? any thoughts or a no go?
No Go, I've read on here that the alphabet cams will not work with SD at all.
Conaski will probably say the Crane cam, I've read that the GT40 heads will bolt up and run but since you have SD your motor really cant compensate for them. Once you do a MAF swap then that would be a great upgrade.
Headers are a great upgrade, if you do LT you'll have to fab up some sort of Y/X pipe, unless you plan on running true duals.
If you put new RR on, you might as well upgrade the springs and get new pushrods at the same time.
i planned on new pushrods, it was the Springs I was worried about, I'm not familiar with putting new ones and taking old ones off. I'll have to get a bad set of heads and tinker with them. I figured the E303 cam wouldn't work, but I just thought I'd ask. GT40 are just an option, I can't find any for sale in my area and am not really concerned about them.
As for the Headers I plan on running True duals so thats not a problem.
First, is my 95 351W a roller motor..? What does this mean? Roller lifters? Hydraulic roller lifters?
Yes it's a roller motor and that means it has a billet steel cam and hydraulic roller lifters.

You don't need new lifters at all but if you buy a new cam it will be know as a roller cam, the ones I recommend for the 5.8 are the Comp cams 35-349-8 and 35-512-8

Forgetaboutit, SD needs a buttery smooth idle or it gets all confused, so compatable cams will have at least 114 deg LSA and relatively short intake duration.. like 212 deg or less.

GT40 heads are good if you can find a set, they flow about 20% better than the stockers. 1.7 rockers are a good addition to the stock cam.. which is a good truck RV grind so you may want to consider keeping it depending what you use the truck for. 1.7 rockers and longtubes will produce nice gains even with the stock heads, if you swap out the cam you may need new matching valve springs.. just depends what one you pick, but the stock pushrods can stay.

Longtubes are the best for truck applications and there are lots that will fit on the vehicle but some fit better than others and make installing the rest of the exhaust much easier. Pacesetter makes a really good fitting set and Flowtech makes the absolute worst fittiing set so they aren't recommended at all.
Thanks Conaski! I knew you'd chime in to help!
Alright, So, been looking more and more at the Comp Cam 35-349-8. This will work with the stock lifters, valve springs, pushrods, and most importantly, the SD?! If I need to change the pushrods or the lifters, that really isn't the problem, it's the springs I'm more worried about.
Along with this cam (35-349-8) would I be able to use 1.7RR or should I just stick with the stock RA??
A pair of GT40's would be lovely, however, people here are absolutely insane on prices, so I'm not too concerned.
As for headers, Pacesetter or Hedman huh? Lew do you run Hedman? if so how was the fit? Any overheating? Problems?

Yes, it pushes the valve springs for all they are worth but it fits. I'd also suggest advancing the cam a couple degrees from straight up for a little extra TQ boost.

Stick with the stock ratio, this cam alone pretty much maximizes the potential from the engine with the stock heads and intake, so adding 1.7 rockers won't gain anything more and requires upgraded valve springs so it is wasted effort.
Anyways, I figured I'd throw these two out there, let some more experienced people look over them and what not.
Of those two I like the Hedmans for the ball socket alone which is a better connector, those Hookers are just a copy of the crappy Flowtech header... both brands are divisions of Holley Inc.
