Need help finding right gasket set
Hey everyone,
My truck is such a mash of other trucks that its been hard for me to determine what parts im dealing with most of the time.
I am ready to reassemble my engine and was looking around for a full overhaul gasket kit. I think my motor is a 351M because it says D7TE-A-2-B on the block and it came out of a 75 F250 (or did 75's have clevelands?). Everywhere i look, they dont give me an option to choose a 5.8L(351) engine only 5.0L 302 or 5.9L 360.
The mr gasket 7127 gasket set looks right for me since they say it will fit a 351C/M and 400. It has tabs off the head gasket which look like the head gaskets i took out.
Felpro lists a gasket set for the "5.9L" but the head gaskets dont look the same as mine. It can be found here:
Felpro Engine Gasket Set
Which set do i want or will they both work?
Thanks,
Jeremy

ok thanks,
I have ordered a set for a 77 351M. What year did ford stop using closed knuckle axles and front drum brakes then? This is what made me think i have an earlier model frame and drivetrain.

351M: 1975/79 Passenger Cars / 1977/79 F100/350's / 1978/82 Bronco's / 1980/82 F150/350's & Econolines.
5.9L was Ford's designation for the 1980's/90's 351W. The 351W was not factory installed in F150/350's and Bronco's until 1981. Econolines got it beginning in 1975.
351M gaskets are not the same as 351W gaskets.
First year for front disc brakes on 4WD's = 1976. All previous year 4WD's had front drum brakes.
btw: Since the 351M and the 400 share the SAME D7TE block casting number, the engine could be a 400.
The bare blocks were all cast as 351M's, but when the blocks were assembled, they could be 351M's or 400's. The bore is the same, the stroke is not the same.
I've typed the following info prolly 1000 times here on FTE: You CANNOT go by block casting numbers to ID what size the engine is!!
Which engine is it? Measure the stroke: 351M = 3.50 // 400 = 4.00"

Yes, but that's not the point.
The OP is already confused, because his truck is a Frankenstein monster.
He thinks the 351M came from a 1975 F250, or says did these trucks come with (351C) Clevelands?
No 351C's were installed in any F Series trucks. 1970/74 Passenger Cars only. 1973/76 F250 V8's: 360/390/460.
He thinks he has a 351M, but since the same D7TE block casting number was used for both the 351M & 400, it could be either.

Thanks for all the help guys, i measured the stroke to be 3.5" meaning its a 351M. The only reason i thought the frame, engine and tranny were 75 was because of the closed front axle and front drum brakes. But i guess that must have been swapped into the newer frame at some point.

I've never heard of anyone swapping drum brakes onto a truck that came from the factory with disc brakes.
I'd be more inclined to believe that you have a 1975 or older chassis that someone installed a 351M engine onto.

Ya i thought the same, i wish i had the 77-79 disc brakes. I have no idea on the original vin since my ownership goes with the 79 F150 body thats been swapped on.
Although my motor mounts look like they have the original riveting, they would have been switched if it originally came with a cleveland engine right?

does anyone know how many spline my front axle is and whether its a dana 60 or 44? Its a low pinion closed knuckle and thats all i know.
I would like to get a lunchbox locker for it but need to know the spline count.

The 351W is a 5.8 Liter. There was the 5.0 and 5.8.
5.9 is the Dodge Magnum.
5.7 is a 350 Chevy smallblock.

Disc brakes were first available in 1976 on 4WD's, which means if you have front drum brakes, the chassis is 1975 or earlier.
Your block has a D7TE casting number which was used for 1977/79 351M/400's installed in F100/350's and 1978/79 Bronco's.
A 351M is not a 351C.

Ill try to find the frame vin tonight, is it on the outside or inside of the frame. I have put a decent coat of rockerguard on everything so it may be hard to find.
So what engine was put in the F100/350 before the 351M?
Any ideas for the spline count on that closed knuckle axle? Does spline vount refer to the number of raised parts or the number of valleys? and do i count it on the outer hub side or inside the pumpkin where the d-shaft meets the gears?

The spline count is the raised part, that is the actual spline. The count may differ from the inner shaft and the outer stub shaft. For installing a locker you need to know the spline count of the inner shaft at the ring and pinion, you will need to pull the axle and count them to be sure. Your axle is the dana 44 and if it is a 1975 F250 congrats you own a highboy but thats a whole nother story and we wont get into that discussion today. Just stick to getting that engine running.
