If I understand you correctly, you have a 1989 Eliminator with a factory issue 460 Ford engine. If this is correct and the engine still has the factory iron intake manifold (casting number is D0OE-9425-C; this number is located on the topside of the intake and next to the carburetor pad/PLEASE VERIFY), then you need the following intake gasket set:
  • Fel-Pro part number 1231
If you have anything other than the factory original intake manifold with the above casting number, STOP and determine exactly what intake manifold is currently on your engine and post a reply in this thread.

The reason for the discrepancy is because the AUTO PARTS STORE is entering into their computer the year of manufacture of your 460. The specific problem is that in 1987 the 460 passenger vehicle engine became a fuel injected engine with E7TE casting cylinder heads (with round intake ports). Your marine issue 460 is more than likely using carburetor-applicable D3VE casting cylinder heads (oval intake ports), although you will not likely find this number on your 1989 cylinder heads.

On any year that both the 429 & 460 were manufactured, they used the same heads that given year. Therefore, your D3VE heads were available on 429s in 1973 and on 460's from 1973 to 1986 passenger vehicles. 1987 used the E6TE casting, which is essentially a D3VE head ever so slightly revised (external appearance only). After the E7TE fuelie head that arrived in 1988, there was actually a little known E8TE head which served mostly on motorhomes (that were emmissions lenient and still used carburetors) and possibly served as a factory replacement head as well.

Your 1989 Marine 460 is rated around 340 hp, has a 429 Cobra Jet (-like) hydraulic lifter camshaft, 429 Cobra Jet intake manifold (which you just confirmed), Cobra Jet connecting rods, valve spring cups (passenger car engines did not have these), fully grooved main bearings...all of which is what the majority of 460 marine engines came with. BUT, your engine almost absolutely has a set of very rare forged flat top pistons (made for Ford by TRW) that bumps your engine's particular compression ratio from the standard 7.8:1 to about 9.1:1.

With cylinder head port work and a bigger carburetor, 400hp is acheivable. Swap the cam/valve springs for more aggressive pieces and 450hp is quite doable. I have the same heads and am somewhere around 550hp, give or take. That being said, the D3VE heads are essentially at the bottom of the food chain in the heirarchy of 429/460 performance heads, but they can be made into decent heads, relatively speaking.

I have started using the 1975 F350 460 combo if they have to ask for a make and model. That 460 has the oval port heads and intake. Saves a lot of BS with some kid at a parts counter who's only interest is a Honda Civic.

I also had a 1970 "T" Bird that had a 460 in it, this was a very limited edition, and the "T" bird parts books only showed a 429. The one with the 460 was actually a Mercury Mark IV with the "T" body. That one was a bitch to buy parts for as well.

Ford guru for sure. Now on the 351, what is the diference between the marine version and the outomotive version? This bites alot of boaters, with auto shops working on the engine.

Whoa, thanks guys but I am not a Ford Guru by any means; I confess I am a bit of a 429/460 fanatic, though. :D

p.s.: 058 is the Ford Guru.
