I'm thinking it's an easy 75-100lbs heavier than a 5.0.  Doing a 351 swap isn't really that bad at all...but the price of things tends to creep up on you if you're not prepared...all in all, not too bad and an excellent end result...just wondering how long the T-5 will live behind it...lol.


The entire swap is heavier, yes, but much of that is in the block. The rotating assembly is a different matter, in how the motor spins.

That was another factor in my decision. The car was getting a T5 come hell or high water, and I was concerned the tranny wouldn't live behind a 351...

As long as I don't beat the hell out of it, the T5 should live an okay life...but that's easier said than done.

So do stock AOD's.  The options are spend a bunch of money on a built AOD or spend a bunch of money on a TKO 500.  That's if it's to live a long life behind a 351.  BTW, I don't think my 7.5 is very happy...I'll have to swap in that fresh 8.8 with 3.73's I guess.

The C6 is stupid heavy and takes up a lot of real estate...that and the fact it has no OD...the T-5 should be okay for now.

As long as I don't do too much of this ---> :burnout:

Actually 1st & 2nd are fairly stout in a T5(but it's fairly easy to tear up the syncros and destroy the mating teeth for the blocking rings), it's 3rd that's a POS...

Ran the first full tank of gas through....and with very little abuse, I was able to average 14.5 mpg...before the 351 swap I was averaging around 16.5mpg...I do a lot of stop and go driving and live close to work.

I don't think the reason for the decreased fuel economy is simply just "a larger engine", I think it's a combination of a junky HO intake choking it off and 1 7/8" tailpipes causing the engine to work hard just to pump air through.  Wish I had money for bigger tailpipes...lol.  I would just cut them off, but I know it's going to get much louder both inside and out.  Maybe I'll put the pro-chamber back on then cut the tails off and see what happens.  2 1/2" all the way through the back of the glass pack then BOOM, restrictive tails...lol.

Besides the idle only going so low (625 rpm's minimum, more fuel at closed throttle due to more displacement) and heavier rotating assembly, there isn't much more that would affect overall economy besides the right foot. I would think that with enough money for a lighter and better balanced setup, you could actually get the same economy as the stock 302. Tweak the idle to 535 rpm's or so and closed throttle would be the same, all else equal.

Glad it sounds like it's all running well.

I don't expect it to get better fuel economy than the old set up, but by improving the efficiency of the intake and exhaust, I should be able to improve it a bit.

I pulled codes tonight just to see if there were any issues even though the light wasn't on.

I pulled KOEO-81,82...which are "air management circuit 2 fault" and "air management circuit 1 fault"...that's to be expected because I never pinned the TAB and TAD solenoids back in.

I pulled KOER- 44,94...thermactor air system inoperative #1-4, #5-8...that also was to be expected as I don't have any air pump or related equipment on the car.

I didn't get any codes from the O2's, so it's nice to know its running within the factory accepted a/f ratio.  No "out of range" codes for any other sensors, so it all seems to be good.

I don't expect anyone to think that but it would certainly be possible with those and perhaps some other minor tune adjustments. I doubt a 500rpm Windsor would ever be that smooth though. I've played with the idea of lowering my idle a little to see what I can pull out of city economy but making only 80ftlbs at idle, I doubt there is much to gain without other problems like alternator output.

Yeah, it would probably sound AWESOME idling around 500rpm though...lol.  I might mess around with that later on, just to see.

Ok. I got the bug. I picked up a 96 5.8L engine. I am getting the pan from a 351w 85 Grand Marquie. I am useing the Bronco Adapter for now.

I just want to get the engine runningin the car then modify it later. So I am going to put headers on, get a h pipe and cat back Magnaflow, a 89 distributer from a truck 351w,put on the adapter and toss the old 5.0L upper on, mass air for the 19's lbs and a A9L and do the wiring swap from a Non HO to a HO. I will stick with the truck cam for now.

But I have to ask, what flywheel or flex plate do i need? I heard just to use the mid 80's Crown Vic one with the 351w.Is that right?

Also how was the wiring for the computer? Did you have to change the wiring for the injectors or is that done through the pcm?

Oh and the A/C is the only problem you had with the hood clearance? ever thought of spacing your K-member like the big block swap guys do?

Thanks for the help to make me do this instead of the 460 swap.
