351w

More information at

Just some food for thought on this. First, the 351w truck motor may have a little more torque but allot less horsepower. Is the 88 E350 speed density or MAF? Leave the stock injectors on the 351, they are rated fot the engines hp. I wouldnt be surprised if they were 19lb injectors just like the 302's h.o. motor. I would swap the 351's computer with the engine otherwise you would have to get another computer set up.

Swapping the computers may require swapping the wiring harness for it to be compatible. I would rather get the chip (and a better tune by default) than go through that hassle.

MAF needs to match injectors and computer I think 87 was the last of the speed density. Not sure about the air temp sensor location and its calibration in computer

With a chip the MAF and injectors don't have to match. It can be programmed to compensate for the discrepancy. Also, 1988 (except for California cars) was the last of the speed density systems.

The groundpounder(302) and the winsor(351) engine are the same except for displacement... probably a longer stroke. Same block, heads and rollers.

I defer to you on the block but the heads and rollers were same. I stand corrected. I knew it had a longer stroke, as you say. Hope he measures that sucker first, then.

Then the taller 351 will need a shoehorn for the hood. All else should be constant though. Keep slammin till it latches....lol

I have had owed ford V8's including 4.6 litre, 302, 351W,

351 Cobra Jet, 429 Cobra Jet and my fav was always the 302. Indestructible and reasonable on fuel. Had two of them...

Cheers,

The only head differences that I know of were on the first 2 years they built the 351W back in 69 and 70. Starting in '71 they both used the same head which came off the 302. The earlier C9 and D0 351W heads were better than the 302 heads and flowed more. It was just more cost effective for Ford to use the same head instead of using 2 different ones when the penny pinchers started getting involved and just as the EPA started getting "uppity" about the environment. The smaller heads choked the 351W.

I found out the hard way that the height was a pain in the ass when I slammed my BRAND new paint job hood onto my JUST installed 351W and put a giant dent right smack in the center where the air cleaner center post sticks up. Wouldn't have happened on a 302. :(

Went straight to Checker and got a drop base for the air cleaner.
