Hi all. I could use some help figuring out what motor and heads I have and what mods I should do.

I bought a used rebuilt motor that is supposed to be a 305.

Besides opening it up can anyone tell me from the numbers what it is?

The block number is 14016375 it also says Y144531 and CFD 107 GM

I found the block number to show 267 and on some sites they show 305 and others don't list it. I did find a site that shows the pre-fix CFD to stand for a 305

The heads (also rebuilt) have number 354434 on them wich shows 262/267/305 heads. I remember reading once that 305 heads are not the same diam cumbustion chamber as 262 and 267

So as you can see I am confused a bit. I could sure use some help.

There is an edlbrock 600 cfm performer carb and an edlebrock performer manifold on the motor.

If this is a "junky" year 305 what mods can I do to improve it besides headers?

What cam would be good.

Also what can I do to the heads ? are they any good or worth porting?. I have a set of TBI truck heads but I would think they would not be a much better swap.

Let me know guys I can really use the help

i have a 305 TPI right now. I will tell you this. I have sunk quite a bit of money into this car. i have custom exhuast, ignition, switches, intake, all types of mods...and i wish i could have my money back to build a 350...45 more cubes man, think it out, the motor swap isnt that difficult, especially if it is carbed. $1200 to get 265hp and be almost maxed without hopping into the motor...or $1200 to get a 350 that starts at 265 and has potential for 500hp+. Good luck

 

Honestly it isn't really about the 45 more cubes either... though it isn't bad, it has more to do with the valve placement and such. Look at the Ford 302, you don't see many people bitching about that motor, but it has a 4" bore. Ask that Devil guy, rotten attitude, but he knows *some* stuff. He'll talk your ear off about this one.

 

Thanks for the info

I know all about the issues with a 305 vs a 350 build.

The problem is I don't know if I have a 305 or a 267!

Unless I open up the motor and measure the bore, I don't know how to figure this out!

All the numbers I keep finding on the casting number sites show different info.

It is a fresh rebuilt motor with less than 2k miles on it and I got it for 200 bucks! the seller needed money and room in the garage.

If it is a 305 I would like to toss a few goodies onto it so make it a better daily driver.

So once we figure out what it is I can use advise on modding it.

I can still use some help with the numbers.

Thanks

 

You don't hear anybody bitching about the Ford 302, is because thats the only motor they have. But you can bet your *** as soon as they get the chance they stroke them to 347.

 

1) Umm.... no. By far not true.
2) How is this different than the Chevy 350 to 383?!?

 

well, i bet it is a 305....and if you want to mod it, just do bolt-ons...Some long tube headers would be good, maybe an exhaust cut-out. Also look into getting a cold air intake. What i would do if I were you...mod everything that you can that you know will transfer over if you have to do a 350 swap, that way it is money not lost.

 

They only have the 302 and smaller engines. Anything bigger is like putting a big block in them.

Its not like SBC's where there are 305's, 350's and 400's all the same size externally.

 

He says...

"Yes, actually it is. You just need to get the right 351. And actually, to correct my earlier statement, they do bitch about the 302... after they hit about 500 hp or so. -RD"

Beats me.

 

I've seen alot of 351W swaps that looked pretty easy?

But yes I see what you're saying in that ford is lacking in motor choices.

Eh screw it, let's throw a 460 in that 89 LX and see how it runs then!

 

There are two 351s. The windsor is a small block, just like the 302 but with a tad taller deck. Fits right in. The clevland is the big block and needs some help. The point is many opt to stay with the 302 or stroke it like the 350 to 383. It's not because they have no other choice. The 302 has been proven time and again to make power, easily better than the gm 5.0l version.

 

But with the Windsor based swaps you need a new intake or intake spacers.

 

"Tad taller deck"

And who in their right mind would use a stocker. If we're we are no talking stockers then the argument is moot. :shrug:

 

351W and 302/289/26? aren't the same base, 351 is physically larger, about an inch longer and comes to an inch or so wider up top.

ME is correct, not *exactly* like swaping from a 262-400SBC, although for the majority of brand F applications, it'll work...thosde of us in our 35/36 brand F's, need that extra inch, so we stick with the smaller motor to keep a little bit of leg room.
