Calling all Ford Gurus.....Will this work?
I have found a 302 bored out to 312 (that would be 60 over right?) with a 272 street cam (he doesnt remember the specifics of the cam) and flat tops that runs good with about 1500 miles on it. it came out of a 85 mustang that the trans went out on so they pulled the motor and its been sitting. He is in a tight and will take 300 cash and some of my junk I have at the shop as trade. Will this be too much for a 94 F150 with a stock computer? I cant see passing this one up and I would like some more get up and go when I mash the go button, so to do or not to do? That is my question. I still plan on putting the E-fan, headers and exhaust. Thoughts and opinions welcomed here.

if you dont have a electronic trans... its easier.. to make a costum computer...
and i think you have to make it MAF im not shure but the cam is to much for SD
or make it Carbed and get an electronic trans controller if your truck has one

"272 street cam" tells us nothing about the specs, you'll have to find a cam card to figure out if it's computer compatible..... I highly doubt it is. It's still a good motor for $300 you will just have to come up with another cam to make it run under EFI.

Exactly what con is saying.. you have an SD computer.. unless you want to swap it's most likely not a great idea.. find out the specs of the cam if that's possible. It might be swappable but there's a good chance it won't react well with your SD comp if it's out of the range. MAF is the best choice, but SD is tuneable.

This is what I dont understand, My truck has a MAF sensor on it so is it MAF or SD? As for the cam I know that tells me nothing either and thats the most crutial part of an engine build is selecting the right one. What is the profiles of a cam that is compatable with the computer? 272 is advertised duration so at 50 th. I would say its 220-230 duration and 480 lift 110-112 lobe sep. that would be my best guess but I want a cam that I know will work.

The MAF sensor will work but it will get confused readings because it assumes you have a 302 engine in your truck. If I remember right you are allowed a 10% variance on most of your engine specs that the computer can compensate for in its programming. So, assuming the 10% variance you are well within the programming specs for a ~312 ci engine. Read up at fordfuelinjection.com and you will get an idea how much variance your stock computer can handle on the engine. The other issue is the cam, car cams are nice and great for low body weight/high rpms but from my reading here they do not perform the same for getting a heavy truck motivated.

I planed on selecting a different cam one with a range of idle to around 5500 tops.How much can you wrap a 302 up too without compramising reliability? I was just needing a starting point or something to base my selection off of. How much lift will a 302 take without any problems? WOuld it be worth it to put a different set of heads like GT 40 heads or will the ones off this motor flow fine for what I need. like I said I dont know much about fords so any help will be appreciated.
"Oops, your name is misleading. I just assumed you had an '88. Lol."
No I had a 88 chevy and a 88 toyota when I came up with that and just kept it. Kind of a weird name but it works I rekon.

If your engine bay looks like the one in my sig then you've got MAF....I put some GT40's on my stock 302 with 1.7RR's and it livened it right on up.......good luck...I second that you'll probly have to pout a less wild cam in her.Luck
