i got ford 302 outta a 80's mustang and i m beff it up for my truck. i purchased a medium cam, cam bearing, hardend push rods, roller rocker (1:6), complete gaskets. the motor has been converted to fuel injected. i wanna keep it that way becasue my bronco is fuel inject and i like the system and i have to stay with fuel injected because i have a electronic trany that need the tps to shift. does anyone know how much over i can go with the pistons without chaging the factory Ford 5.0l intake? i was thing 30 thou over is that to much or can i go bigger?

i also purchased a timing gear set. if i put them in will they afect my timing? i heard there was a possibility that it could have some effect on knock sensor? i dindt even know the 5.0L had knock sensors.i might not sound very copadent but this is the first attempet at building up a fuel injected engine.

any advise is greatfully appreated.

 

What year was the mustang motor?
What year is your truck?

If the Stang motor was '87 or newer you want to retain the stock camshaft because it's very good and EFI friendly. Overbore has no effect on EFI so give it as much as it needs. The HO motors don't have a knock sensor so you can use the gear drive set.

 

i wish i new what year the motor was but i dont . i dont think is an HO tho because it didnt not have roller rockers and my truck is a 93 fullsize bronce with a fuel injected 302. i was told that if i got to big with the pistons that my stock intake would give me enough air? is that true

 

and the motor is older then 87 that i know because the guy who hade it before me had converted it from carb to multyport

 

OK.. what is the block casting number then.. you'll find it down on the left lower side looking at the motor from the front. And same for the heads, casting number is near the intake ports on the head gasket side on those.

I'm guessing you will be using the EFI intake and all accessories from the truck? Is your Bronco mass air?

 

yes it is mass air . and i will be using all the parts as far as intake and sensor from the and i will have to get thos numbers off the block tomorow

 

If its got the HO cam you should be good , the truck 5.0 intake is very good i would keep that , 1.7 rockers wouldn't be a bad idea either ....lew

 

i arleady have the cam so i m gonna put it in but m i safe to go 60thou over then?

 

What ever the machine shop needs to do , i would leave it up to them ...Lew

 

60 over is a little much to me. i wouldnt go over 40 over.

 

If the motors never be boared , 30 over may be ok , the machine shop will know , going 60 over won't help much if you don't need to .....

 

ok i was gonna go 30 over so i should be good to go then.

 

What cam did you buy? What is the grind number or part number and is it a flat tappet or roller?

 

the cam is flat tappet, and it a howard cam . i just talked to the machinist i m just gonna bring him the motor and parts he is gonna do the work for me. but he told me that 30 over will be perfect for my application and if it helps at all the motor is a four bolt main ...but i the motor is two hours away from me so i cant get the numbers of it

 

Hmm... Have you visually verified that yourself? The reason I ask is because there are no 4-bolt main production blocks, so if you have one it's an aftermarket block.. which is a bonus. But if you were simply told it was a 4-bolt main I hope you didn't pay a premium for it unless you actually got to see the 4-bolt caps.
