Hi I’ve read a lot of these post and have a lot of questions. I have a 93 F-150 with a 5.0. I pulled the motor out to do some mods but nothing crazy. I’m confused on the whole sd and mass air thing. But this is what I need help with. I’m putting stock gt-40 head, headers, 2.5 pipes all the way back with no cats just flowmaster of some sort. What cam can I use that’s compatible and will the stock rr on the gt-40 heads be ok or do I need to look at 1.7s? ( it will be my daily driver. I will also haul a car trailer with a car on it every now and then.) or any advice will be greatly appreciated. By the way it’s 2 wheel dive 5 speed

 

Stock 1.6 rockers(or roller rockers) will be fine.
A cam with higher lift on the exhaust than intake is ideal for Ford small blocks.
A cam and upper/lower intake that is set up for 1500 to 6500 rpm is also much better than an idle to 5500.
The stock intake is giving up around 5k rpm, where the engine can continue to make good useable power well past 6k.
Those engines also like more timing, moving the distributor from 8 to 12 degrees at idle.
An adjustable timing set also allows the peak hp and torque to be moved to either low/mid range, to higher up in the revs.
Advance the timing on the cam gear for more low rpm power, more useable in a truck/ tow vehicle.
There are alot of small and simple changes that really wake up a 302/351w.
They also benefit from a bigger mass air meter and throttle body.
Stock injectors should also be ok.
A larger fuel pump is recommended as well. There is a stock pressure regulator on the fuel rail, so the engine is Not going to get too much fuel. However, the stock fuel pumps were known to not flow enough fuel.
The 88lph pumps in the stock 5.0 mustangs could not keep up. Add a bigger pump, and you got more peak hp.

 

Thanks for the info
