Intake manifold question

[northplainsdrifter]

Will a AMC 304/360/401 intake manifold work on a Javelin 390? I'm not familar with the 390. I'm trying to sell a Edelbrock Torker and that question came up.

If it's a 1970 390, it will bolt right on, 69 or older will take some mods. The 68-69 390 had a shorter deck and the 2 center bolt holes were different. You can slot the bolt holes or re-drill the heads to match. You may need to mill a bit from the mating surfaces of the manifold because of the shorter deck.

Perfect, thanks Bob.

I have another question, will a bellhousing from a AMC V8 work on a 258 6cyl?

Never mind about the bellhousing question as google is your friend! This is what I found if anyone is interested.

BELLHOUSINGS
'67 and later V8s (290/304/343/360/390/401) have a different pattern than '66 and earlier V8s (250/287/327 only).
All '72-up (calendar year) AMC sixes and V8's have the same bellhousing bolt pattern. Only difference is depth of bell and consequently the length of the transmission input shaft. They can be interchanged.
Some early '72 models might have the old six bellhousing pattern.
Generally all AMC's of the same year and engine will have the same transmissions, Changeover years (eg. '75-'76) can be a tossup.
The Jeep 4.0l [typo?] bellhousing will work with the '72-up AMC six.
The four cylinder uses same ford-style trans as sixes/v8s but have agm [typo?] bolt pattern on the engine side.
The six cylinder bellhousings are 6.5", V8 is 8"
T-96, T-14 [in cars], SR-4/T4/T5 and 150-T are 'short' and the T-89, T-86, T-10, and T-15 are'deep'.
Some 304's in the small cars used the six cylinder bell (for example the SR4 equipped 304 and t-14 equipped, early-mid '70s).
The 150-T and SR-4/T-4/T-5 are two different bolt patterns.
Ford bellhousings of the right years are often drilled with both Ford bolt patterns (meaning the one AMC used as well).
AMC used a multi-pattern bellhousing from the late 70s-'83 which had patterns drilled for T-96,T-14/T-4,T-5 & SR-4.
The T-5 was optional on any AMC T-4 application and should use the same bellhousing. (also shared with the SR-4, some are also with some 150-T's). The original Ford bellhousing wont work.
The AMC 150-T has a GM 2.8 60-degree bellhousing.
There has been a report of a t10/early-six bell ('mexican' bellhousing). It's definitely the right shape for a GM bolt pattern, though not drilled, but no GM trannies with an 8" input shaft that seem to work with it.
