I've searched all over the web and all the books I have but I cannot find good answers to the following:

1. Was there any difference between the 1958 430/375hp Lincoln engine and the 430/360hp Mercury engine?
(If so, what was it??)

2. Is it true that the only difference between the 430/360hp and the 430/400hp was the intake and the 3x2v?


My search did remind me that the origin of the famous "Holley List 1850" was in fact none other then the 430-4v of 1958!

Hey, if you're up for a 3rd question:
3. What color were these engines in the Merc and the Lincoln?

Thanks if anyone can help with these questions.

1. There was no major difference other than carburetion type and exhaust manifold type.

2. Yes, just the intake and carburetors. There were other slight differences, i.e. the fuel pump.

The HOLLEY 4150 was introduced on the 57 FORD.

3. The 58 LINC 430 was a green with yellow rocker covers and the 58 MERC 430 was gold.

Kultulz,
I know, the first Holley 4150 was on the 57 Ford, I recall driving one. I show that one as a List 1272, a 390cfm version.

What I meant about the "List 1850" variant was, the "1850" is so common today. If you want a 600cfm Holley, on the wall of many auto parts stores there's a brand new "Holley List 1850" hanging there, the generic $20.00 swap meet Holley. I just didn't know, it was that particular List 1850 number that was first used on the 58 430-4v.

And to think I tuned the idle on ours and didn't even bother to look at the list number!

I see what you mean now. The HOLLEY(S) used on the 58 MEL did not have external float adjustment. One had to remove the bowl(s) to adjust the fuel level. The adjustable fuel bowl came out either in mid-58 or 59 production. I can get you the exact date if needed. I am not sure if this was the introduction of the 1850 or not but am curious now.

The Shop Manual does not give CFM. It gives the venturi size as (430) 1 1/4" Pri and 1 5/16" Sec.
