Cam for the 3.8 Reply #6 – February 16, 2010, 12:27:35 PM No problem. Glad to be of help. I run an ISKY race cam in my race car. They might have cams for the 3.8. Quote Selected
Cam for the 3.8 Reply #7 – February 17, 2010, 03:26:09 AM Looks like the comp cam are all for the roller cam. My 86 is a flat tap. Looks like ISKY has cam's for the 86 flat tap though. I think I gonning to have to hit you up for all kinds of info. Thanks for the help again Chris :-) Quote Selected
Cam for the 3.8 Reply #8 – February 17, 2010, 10:31:50 AM You might want to consider converting to roller, if you have the motor down for the cam anyway, I think you just need to swap the lifters, but you may need to change out the pushrods and rockers as well. Any later model stock pieces should work fine, and it'll free up a little something, not to mention the added benefit of newer components in there. On my old 83 3.8 one of the lifters(Flat tap) decided it was time to disintegrate at about 184,000 miles. Pretty much ruined the motor, but I had actually thought it was a main bearing that was making all the noise. Quote Selected
Cam for the 3.8 Reply #9 – February 17, 2010, 12:16:46 PM Quote from: Cougar8775;310327why not run a SC cam?The SC cam has very little valve overlap because it's designed to build boost. I would imagine it would run like diarrhea (slowly, down the back of your leg) in an NA application. Might develop a little more bottom end but your top end would probably evaporate. Quote Selected
Cam for the 3.8 Reply #10 – February 17, 2010, 12:54:54 PM If you can go with roller instead of flat tappet I'd do it. With the reduction in ZDDP in engine oils there have been a lot of flat tappet cam failures. Harder and harder to find the required ZDDP and $$$$$ increase significantly if you do. I believe COMP has a bulletin on cam failures because of lack of ZDDP. Quote Selected
Cam for the 3.8 Reply #11 – February 17, 2010, 01:51:47 PM From what i have read the roller was used from 88 onward, and was a totally new block.http://www.enginebuildermag.com/Article/2393/rebuilding_the_ford_38l_engine.aspxI wasn't sure if a roller would work with out some major work done to the heads or block. I have heard about the oil. Had a couple people say if you move over to the synthetics like mobil one, you should be fine. Quote Selected
Cam for the 3.8 Reply #12 – February 17, 2010, 05:31:59 PM Yea...From what i recall looking into going Roller on my 3.8 awhile ago (Using JY Parts). I was put at a halt due to major differences made at 1988.Not just a drop in deal like the flat tappet versus roller 5.0 cams setups.If anyone knows anything further that would work, Info would be much appreciated.

Cam for the 3.8 Reply #13 – February 17, 2010, 06:42:35 PM Ok, so, I'm thinking what you should do is to call a customizer like Tom Morana in Canada(Good guy, BTW) or just any good cam shop and ask them about having a roller cam made for your engine. From the looks of that article, the balance shaft is the problem, and there were applications/years of the 3.8 made without a balance shaft, so I can't imagine that it couldn't be done. Call and say you have an 83(Or so) Ford 6 with a flat tappet and that you would like to convert to roller and see what they say. Can't hurt to ask. As far as the rockers go, I'm sure there at least one or two roller rockers that will work with your heads as far as mounting, I even hear of 6's using v8 rockers. Quote Selected
Cam for the 3.8 Reply #14 – February 18, 2010, 10:13:43 AM Glad to be of help. If you need extra ZDDP, run Rotella for Diesels-as long as you don't have catalytic converters. I use Rotella and Brad Penn oils. Most vintage race cars use one or the other, and none of the cars have cats on the track so it isn't a problem. The Brad Penn is expensive but they are the best. Rotella is available at Wal Mart and just about anywhere I go. I'm using Brad Penn for the 2010 season after using Rotella in 2008 and 2009. A shop I know had testing done on Brad Penn and they found it was the best for race engines. From what I recall, all V-6 cams are re-grinds. I might have an old 3.8 page from the Comp Cams catalog I can locate if needed which would have specs. Comp can just grind it to whatever spec you want. The V-8 rockers should be a direct swap into the V-6. It's still on my list of things to research, but I feel strongly it does work.Chris Quote Selected
