ALB: AL Correct?
Well, as promised I said I would share my current set up and my thoughts on my next super secret engine / trans set up.
So currently I am running a:
1903 cc aluminum block 77hp 105 ft lb torque , Weber 44 idf's, engle w-100 mid range cam. Trans is a 3:88 ring / Pin....... 3.81 1st, 2.06 2nd, 1.22 3rd, .82 4th.
Currently I can cruise in 4th 3500 rpm @ 88mph with ease, I'm not messing with you either. LOL 
Pat said I've been lucky my engine is strong..
Here is how it all started with the transmission. I was tired of doing high rpm low speeds on the freeway soooooo.. I had .70 4th installed but it was too tall, even though it never lugged the engine it was too tall and I had to have high rpm's shifting from 3rd to 4th, but it made for awesome cruising down the freeway with plenty of room, low rpm, high speeds...lol lol
So I was introduced to Scott Sebastian (Metal Craft) he is our local transmission wizard. This guy is really a mad man. Any visit to his shop will verify his credentials as he receives transmissions from all over the US for rebuilds.. He is in demand!! We sat down, told him what I wanted to achieve and there ya have it. (SEE ABOVE)
Currently my car is close to my preference 1st and 2nd are not stump pullers but I can keep in them longer than most but not long enough.
The way I see it air cooled engines like ours need to be kept cool, especially if you put a big power plant in them.. The bigger the engine the hotter it will get. Its my understanding that type 1 engines need to keep a constant 3 k or higher rpm to help with this process.. I did experience hotter engine temps with my .70 4th so, I don't see how adding a 5th gear to lower the rpm will help, but maybe I'm not accurate in my thinking.... I will entertain feedback though
Again I stress its all driver preference.. I'm not looking to have my car do well in a quarter mile.. So I will go consult both Pat Downs and Scott Sebastian in my super secret build (aka: PROJECT SLEEPER) and we will come up with a combo I'm sure will match what I want, which is a reliable car that will get me to the coast a half hour faster... LOL!!!.... and go to 11 1/16 !!!!!!! TED!!!!!
