Folks; for a ‘93 351w m/t, I would like other light ideas for a build. I can’t spend a fortune FYI.
Im planning on:
- Stinger performance pimpx computer (with O2 sensor and such)
- Long tube headers + exhaust
- Oil pressure sensor (electric, recommendations?)
- * Crane 444232 cam *
- Electric Cooling fan**
- smog delete***
* For that cam. What other upgrades do I need to make for that to run and not damage anything else, and see it run properly?
** Recommendations? The truck got hotter than I would like when pulling some of these high elevations passes.
*** Ive seen folks run just a shorter belt, but I would like to truly remove it and the lines running to the CAT. I have seen a couple kits but whats the best was to do so.
IF I put in the cam, I plan to replace all the seals, water pump, timing chain, and any other commonly replaceable parts.
heads are a possibility if funds are there for that.
Smog delete is fine but what you need to make the serpentine belt work depends where the tensioner is on your motor, if it's up top the belt routing will be OK for a shorter belt but if it is down on the side the tensioner won't work without an idler puller where the air pump was.
Overheating could be trans related, the E4ODs run really hot so an external cooler isn't a bad idea.

Thankfully E4OD isn’t my issue
Sorry should have out that up front that I have a manual trans.
The tensioner is up top, but I would like to keep the belt and all that the same.
Right now I just want the truck to run right at elevation, have more power, and better fuel economy.
After reading that, it seems I need heads to help with air flow. However, if I go down that rabbit hole, whats really the right size to run given I do need power to tow a small trailer (5,000lbs or less, really looking at a trailer with a side by side or two ATV’s) in the next couple years.
maybe 30lb?
Really? I keep hearing that the most hp you can get out of a #19 injector is around 260-275hp. Not more more than stock roller right? I too want to know.
Bigger injectors aren't needed and will just mess up fuelling and totally kill fuel milage.
Any codes? The motor should run fine at elevation so something isn't right.
None. Motor runs fine, just getting old and probably a semi-plugged cat and the ever-persistent exhaust leak.
I will say it is WOEFULLY underpowered. Even at ~2700-2900rpm in 5th, 4th is required to hold speed, grade and distance depending. Thats with 4.10’s too.

That is mostly correct and a 5.8 will not exceed that output with the stock heads and intake. 19lb injectors will supply more power with more pressure behind them or if pushed beyond the standard 85% duty cycle limit.

Some reading for you.
At 85% 260 is probably about the max the 19lb will allow.
Personally, once the basics of my build get done, I would like to run up to 300hp and see if that suits my needs. If not, well a stroker kit and turbo sound fun.
As it stands, my ‘93 will stay my Hunting/fun rig. Wife wants a newer crew cab truck for us and towing a camper....
Sounds like Conanski knows more about this than than I do.
But, I thought I’d pass this on. This is what I received from Compcams a while back. I emailed them asking for a recommendation for a cam for my 96 F250 351. They were great to deal with, on the spot, and happy to help / suggest with my requirements. I asked for a recommendation for A general use pickup, occasional towing (6-8000#), plowing and bit better mileage.
