hey yall im new here and i need a crash course in speed density and making power around it or with it. i have a 89 xlt lariat 4x4 always does what its told, satisfaction and reliability are through the roof. but i really wanna see and hear that 351w move you know.
i just want a basic understanding of speed density and how some bolt on power would react with it, all this talk about cams and how it lowers the vaccum , to cause undesired responses has me worried

Hopefully some of the experts will give an opinion soon.

 

thats what im talking bout thanks , excactly what i needed

 

Where are you at in NJ? We are in franklinville,nj (south Jersey).

I was entertaining the mass air idea myself, but figured I had a 6000+lb truck just how fast is it gonna go!? So I cammed it for low end and did a high flow cat and single exhaust. It gets out of its own way now, but still is no race car. But it pulls well enough for a 5.8 small block. The mass air switch over is easy enough to do with pick and pull parts.

 

Also there are many off the shelf camshafts that work well with SD.

 

small world I`m from Franklinville also right behind the old colesmill tavern.

 

Howdy neighbor! Over here on Leonard Cake rd by the police station!

 

No **** I`m down that road alot taking my son to his friends house on leonard cake rd.

 

Yup down Leonard cake rd past Oak ave 2nd house on the left, got the blue ford and the black ford pick ups in the driveway. Possibly you have seen the black stepside rumbling around town, can't miss it if ya seen it or heard it lol!

 

I really like that stepside!

I didn't see a link to ford fuel injection yet.

im in salem haha i go to franklinville with my buddy all the time it helps when you have a hemi for a recovery vehicle , ever been to gleasons im usually there once or twice a month after a good ride, so neversosure u did the cam first? im looking for nice low rpm cam im always towing some one, some thing or pulling a bogger who got stuck for a decent buck , but how much did that mass air conversion cost you ? i went to shorty's u pull it (on the black horse pike) and i cant find a cpu that has the 5.8 and the c6 trans for the conversion.

 

Ok you live right across the street from the Brady`s.

 

I know where Gleasons is, but I gave up the bottle so I don't get there much .

I was going to do the mass air conversion but stayed with the Speed density. I didn't need the mass air conversion due to the size cam we put in, I will dig up the cam numbers, I know it is a compu cam.

The mass air conversion is only a few bucks, need a puter from a 5.0 and the parts. I bet it could all be had for less then $75 bucks. Don't worry if you find a stick shift puter, since the c6 is not puter controlled.

We did the cam, exhaust, 5 spd ZF, rears swap all at the same time. We did a frame up build on the 89 f250, put a 96 front end on her then had it painted. Pics are in my gallery of the truck.

Thanks for the comment, she is still a work in progress. I asked about the fuel injection only because I am running in excess of 7200rpm's, the ford 5.0 puters only give you fuel to 6200 rpms. Leaves me outside looking in lol!

I know I could build my own system, but I wanna do it cheaply, with out going to the aftermarket area. Plus I don't wanna get into the burning chips and etc..
