first off if this isn't the right place i apologize, the engine categories were divided up like size, and that's my issue... a while back i bought a truck that wasn't running, and the guy told me it had a 302 in it. that's what the valve cover says, so i figured it was right. come to find out the valve covers i guess are interchangeable between a 302 and 351. the parts for a 302 were not matching, distributor in particular. ford told me if it has the larger shaft between the distributor and oil pump, which it does, that it's probably a 351, and also said there should be a 1ish inch difference between where the distributor goes in and where the intake connects to the block... i think... i know little about engines, but am trying to learn... it seems to have a space of different metal between the block and the intake... but i could be wrong, not having one of each to look at the differences, i really don't know which this one is... i'm gonna link some pictures, not sure if this site likes for them to be posted in here or not, so i'll just link em. there's a series of numbers on the intake i guess is the firing order, tho if it is somewhere a 6 looks like an 8, and it matches up if the first one is a 6 to what i think the 351 is, but i think also i found later 302s use the same pattern, or maybe it's the other way around, i dunno... anyway the truck is a 77, ford, f100 custom, the guy said the transmission is an fmx, but if he was wrong about the engine he could have been wrong about that too i suppose... here's the pics i've uploaded, if pics of something i'm not showing would help, let me know what and i'll go take them, it's no problem at all.

here we go

thanks in advance for any help/input

looks like a 302 to me. The carb is a Ford 2 barrel. The numbers on the intake manifold is the firing order, not a part number. U have 2 fuel filters, one screwed into the carb, the other one near the distributor hole. The photo thats shows a sticker on the drivers side valve cover shows engine size, tune up specs, and emmission equipment. Take a good look at it. DONT turn the engine over with the starter with the distributor out. It turns the shaft that turns the oil pump. BE SURE the oil pump drive shaft is installed. Sometimes it comes out with the distributor. good luck with your big project, DAHMER

 

look at the front of the block where the water pump mounts. if there is about a 1 inch space between the water pump and head, it is a 351. if the water pump is even with the head, it is a 302.

 

i can't tell for sure, but it looks like you might infact have a 351.
here are some pictures from another site to help you identify the 351 against the 302.

As requested, here is a photo of a 351W. I just happen to have one laying around the garage.

Look at the same area on this 302/5.0 block. There is no gap.

the firing order is the windsor not the 302, and it looks as though you can get a socket straight onto the bottom t-stat housing bolt and if that is the case it's a 351.

 

ok, i took some pics of that area of the engine and i'm pretty sure there is the gap... under all the grease anyway lol

perhaps one of you will know for sure, or can request pics that will tell for sure.

oh, and i have no clue what a bottom t-stat housing bolt is, but if someone could tell/show in a pic, i could see if i infact could get a socket there

thanks for any help in advance!

 

Your engine is a 351 W.

 

ok, so most likely it is a 351W i guess... with the gap and the 302 valve covers fitting... the guy and his brother owned a junkyard so that could explain the valve covers and why it's points now and not electronic... anyhow, i have a new question...

a guy at a ford dealership here in memphis told me if it was a 351W then ford did not put it in there, it was a replacement/upgrade, cause ford only put 351M's in them... somewhere on the engine are there numbers or something that can help me identify what year it is and what it came out of to make parts hunting easier? we found the distributor finally buy searching... i think a 71 galaxie, but i'd still like to know what it came out of if possible, or atleast the year, i think engines have serial numbers too, but where could i find it...

also, is there a site with a guide to what exactly each number/letter in the vin number stand for? i'm kinda curious what the truck had in it originally, and this would be useful information for any vehicle i purchase in the future. and what about transmissions, the guy says its an fmx, how do i check that against say a c4 or c6 or something later? ... since they owned a junkyard, there's no telling what's in it, and the guy also said he didn't know there was a bellhousing for a fmx/351 combo. i'm sure he could have been mistaken, but if not, then he must be about the transmission i would think

thanks in advance for any help! and sorry to be such a bother!

 

Trere should be a casting number on the intake that will tell you the date of that. Something like D9AE-AA or something.

oh, and it is a transplanted 351W. There were no 351W installedf in 73-79 trucks by the factory.

 

there is also a block casting number on the block behind the starter, but you dont need that now, we know for sure it is a 351. look for a part # somewhere on the intake or heads. the first 4 letters and numders will be what is needed.
as an example, c7dz would be for year 67. d7dz would be for 77, and e7 would be for 87.

is this what you were talking about, it's on the intake behind the carb.

if so, then we assume it's a 71, or atleast the intake is... ???

 

yup. the intake is from a 71. and judging from the crud and grease buildup on the engine, i would guess that the whole engine is from 71.

 

71 car to be exact. The A probably means LTD or another big car.

 

the A simply means full size car. it does not go to body style, just full size ford.

 

thanks everyone for your help, now that i know what the engine is it should be easier to find parts, tho if i knew exactly what car it probably would be easier...

like when you go to a parts store they want to know what kind of car... so would any full size 71 ford car work? galaxie, ltd, whatever? or are there differences between 351W's in different autmobiles of that year?
