For anyone who doesnt know whats happening with my truck heres the quick rundown. Its The 1990 F150 in my sig, 302 with M5OD trans, extended cab/long bed. In the very near future im swapping a 78/79 Dana 44 solid front and Ford 9" rear, and at the same time its getting a 9" (suspension) lift, to be running 38x15.5 ground hawgs (See my other thread for info about my failed axle deal yesterday)
Now the question, during my quest to find the new axles i have met several people selling various ford powerplants, and since i am wanting to swap engines eventually for more power (after i finish the current suspension projects) so i thought id see what yall think i should go with.
Now this is my DD of course, but this is a have fun thread so feel free to sujest un-realistic senarios (I know yall would anyways)
Options:
-Stick with 302 and bolt-ons
-Build current 302 into 331 stroker
-Stock 351
-Stroke a 351 to 393 cubes
-1978/79 400 (rebuilt with high compression pistons, 4 bbl, headers, RV cam)
-429/460

I know the stroker 5.0 sometimes have reliably issues, from the cylinder wall being 2 thin. I know from my 5.0 Mus that most people go for a 347 Stroker. Never heard of a 302 going to 391. My 2 cents is: THERE IS NO REPLACEMENT FOR DISPLACEMENT!!! and GO BIG OR DONT GO AT ALLL.
You want cubes? I just received my new car craft the other day and found out those crafty fellas over at dart are CNC machining engine blocks from giant billet blocks of aluminum!!!! how does 800-900 cubes sound dude . A little too unrealistic?
I know a saw a 1000 cube BB Chevy some where. Some Race company makes it. I think it was like 20G or more just for the block. Thats INSANE. But for the racers its worth it.
The 347 is my favorite little engine that could.
My dream is a 460 bored and stroked, and while were at it slap a supercharger on it. Then instead of MPG it would be GPM(gallons per mile) but who cares would be alot of fun.
I said 393w. If it's going to be your dd, that is a good driveable choice. It also lets you bolt up your acc. of the 302 and re use your serp belt stuff.
I'd say get you a 460. You can put the same amount of money in a 460 that you would a 351 and be able to MELT the tires off that truck.
Of course your probably going to have to step up from a D44 and a 9" to D60's. Especially if your putting that much power under the hood and with 38's. I'd say the first time you romp on that 9" with about 400 horses under the hood it's going to explode. JMO, or course, but I think you need to step up the gears or your not going anywhere.
Stroke the 351. Sounds like your wanting a show off truck (not a seriuos trail rig). You will be cruizing this on the street and maybe some mud here and there. The stroker will give you the bottem end torque to get the truck from red light to red light. Very doubtful you will see many 5000 rpm top end runs at 110 mph. Go fuel injected. will give you better fuel milage cruising.
The 351w weighs in around 525 lbs where a FE motor is about 200 lbs heavier.
my 2 cents.
I voted for a 5.8 based stroker... I think it'll get the best combination of power and milage. You do realize you need a better transmission for every option except the stock 302...
The 351w weighs in around 525 lbs where a FE motor is about 200 lbs heavier.
my 2 cents.
An FE is only 100 lbs more than a 351w and 100 lbs lighter than a 460. (I hear simply adding an aluminum intake shaves 70lbs off, its not as heavy as people think).
