1990 4-banger to 351 or 5.0

langley · 02-07-2002, 03:28 PM

I have a 1990 4 banger and I was wondering what do I need to swap the 4 for a 351 or a 5.0? besides the engine and the computer[wiring],do I NEED to replace the suspension,rear end and drive shaft?,is it even worth it?.I have a 5.0 litre and I'am going to sell it, if I can get enough money for the swap
Has anyone done it?, how long does it take if I had all the parts sitting in front of me?

Don't sell the 5.0 that you have. Personally, I would build up the 302 and put it in there. The 351 does have more potential to make power, but the 302 can make plenty of power, and you have more aftermarket parts to choose from for it.

If your 5.0 came out of a mustang, then you won't need a whole lot of other parts to put it in your car (unlike doing the 351). You'll need the full exhaust system, motor mounts, all hoses and wiring, a bigger radiator, not sure about the driveshaft but that 7.5" rear will be toast within a week or so of some real power.
The 8.8" rear is a direct swap and can be found easily in junkyards.

I've probably forgotten many things, but I'm sure someone else will come by and help.

good luck with it

I'm going to sell my 5.0 notch and with the money, I'll build the 4 banger.Is this a cheaper route to build a crazy 5.0 or should I just keep the 5.0 and try to save my money for future mods

I'd just keep the 5.0 you have now and mod it.
