It depends on high high you want to rev the engine. GX cam makes maximum HP at 6,400 RPM, if you shift at 5,000 RPM it will make less HP than the stock cam.

DD....I am looking at a Delta cam similar to what another MG enthusiast did and that he posted on this thread. His cam is more that what the GX cam spec is (262° duration, .425 lift...A12GX-256°, .331 lift at cam). He is running with the H89 head which has smaller intake ports than the GX head. If I go with the same cam do you see any idling or tuning problems? Or would you recommend going with the GX spec grind?

Makes me a little uneasy to contradict the Tech Wiki information. I would like to hear from others if they have put an A14 mid sump pan on an A15 block.

That's great news - maybe B210 mid-sump pans all have the clearance. I see in the photo the top pan has bulges in the side.

DD....Pulled an oilpan from a 1978 B210 (mid sump) and set it on the A15 block. Rotated the crankshaft and did not hear any contact with the oil pan. You advised I would need to knock it with a hammer for proper clearance....

Stumblebum if you have a 5 speed with a one to one 5th gear you could easily sell or trade it for a 60 series overdrive 5 speed. We racers are always look for direct drive gearboxes.

Tom

That's already a 60A five-speed.

The 4-speed is faster. Quicker accelerating, with same top speed. But the 5-speed is quieter, with better fuel economy.

For gearboxes you could use the 60a overdrive 5 speed if you can find one, they should be more common than the dogleg in every market. Another option is adapting a Toyota box like the 3t or a project I'm working on, the w57/58 mated to an a series auto bell housing.

G,

I use an H89 head port matched to a GX intake with SU HIF4 carbs.

Here are a couple of pix of a modified oil pan for reference (not mine).

I put a A-14 into a 1957 MGA and am not putting one into a , unfinished , 1960 Morris Minor.. The MG has the dog leg 5sp in it and I just hate it...l did not know that 5th gear would be 1 to 1...so now I am looking for two 5sp transmitions that will fit on the A-14's

I don't know what I a m looking for as I am not all that smart on swapping parts... I have own several Datsun over the years ,,, I know they will run good for a long time.


I live in wheat country and the land is flat... I like to run as fast as I can.. that's why I need a 5sp...


Does anyone know what trans will fit my A-14?

Merry Christmas.........
