If its better, its not by much...

 

The real question should be whether a school bus cam is usable as a core for Racin' to grind into a stage1

 

Nope. same cam. fueling was changed to make different torque and hp needs.

 

Hey there I've got an 86 250xlt on the drive and I'm wanting to do a rebuild on the motor and of course up the bhp. Where can I buy the performance cam and some upgraded head studs + head gaskets I'm in the UK so don't really want to send a core over. I've tried mike jones but literally been waiting on a response for months and can't seem to get through to R&D????

Any help and possibly a working email to someone that is willing to supply these parts would be great.

P.s the engine is the stock 6.9

Regards Luke

 

Justin is a way busy guy... sometimes takes him a little while to respond. You might try a PM but I think you need to have a certain number of posts before you can PM. https://www.ford-trucks.com/forums/member.php?u=242486 He is the source for the stage 1 cam. Russ (typ4) is the source for the torque cam, NMB2 is the source for the J2 cam. Are you going to run a turbo? Which cam are you wanting to run?

 

Typ4/Russ is often a bit busy, but he came through for me, and now I've got a shiny torque cam for my engine, as soon as I can take it apart to drop it in there.
I plan to run it with a turbo -- it should make slightly less peak HP, but make better low-end torque and power, something that I find important(it drops the non-turbo peak torque from 1600 to 1400RPM).

 

I intend to run a turbo and hoping for around the 300 mark so whatever will assist me to this I'm a big idi fan and do a lot of tuning with them over here in the uk it just can be hard to get to get certain parts

 

That is about the power level I am building also. You will need to get in touch with Justin at R&D for the parts to make it happen. You are going to want a boost friendly cam such as the stage 1 or J2 cam. Stage 1is a great compromise between low end torque and high end power and has excellent driveability. The J2 is soft on the bottom end but makes fantastic top end power. Justin is also working on a stage 2 that will be similar to NMB2's J2. I bought a J2 before the stage 1 was available, and it is just sitting in my closet if you are interested in that particular grind. I wanted a stronger bottom end so I went with the stage 1. Be patient and get a hold of Justin. He will be able to tell you more about his new stage 2 that will be going into his build, and discuss your needs as far as a cam, IP, stud options etc., and I am sure he can work something out with you as far as a core.

 

Well I would love to be patient but my trucks engine is out due to some other issues so I'm wanting to tackle two birds with one stone and get her back together asap what sort of money were you thinking for the one you have laying around? Will it work with my standard valve train/rockers etc?

 

You don't have private message function available yet but I left you a visitor message. Your stock valve train is fine with any of these cam grinds, but upgrading to Comp Cam 910 valve springs is highly recommended. They are Powerstroke springs and provide a little better seat pressure.

 

I would go with the Comp Cam Valve springs. The additional $90 is worth the piece of mind. Also if you aim for 300hp, you will need a bigger IP. I think the 110cc pump from R&D will get you close to that.

 

I think Racer30 put one in his mohome 7.3 runs sweet

 

Hi not really sure how to access a visitor message I've tried to find it? How come I don't have the private message function??

 

Visitor messages are on your main profile page. You also need a certain amount if posts before you can access private messages...

 

I got his email address and made contact this past week with him. He is doing a grind this week
