Thinking About Motor for My Current Project

[scarecrow]

OK, I'm starting to do some research into building a motor. Here's my priorities. Reliable life span of 30 to 50,000 miles, low & mid range power/torque. High end not an issue. Want to be able to cruise @ 65-70 mph for hours if necessary. Basically an honest usable 80hp. I realize you can go two ways, bigger pistons or bigger pistons and/or increased stroke. Can I get what I want from a stock case? I'm thinking 1776 or 1835 by way of stock 69 crank & bigger pistons, 110 cam, 1.25 rockers & duel carbs. Am I on the right track? Jack?

Marc talk to Ramone, he has a 1776 daily driver. Not sure of the details besides that.

Bridgette and Midred both cruised/cruise fine at 65 - 70. =-)

Your on the right track with what you want to do and a reliable stock 1600 like I built for TheStrap will also give you "

Are you saying I should stick to a 1600?. Wanted a little more power. That's why I way thinking of bigger pistons, a little more cam & duel carbs. Should I buy a new case or get an used one & have it machined for bigger pistons

Yeah so can I but I'm always worried that I'm pushing it too far. Especialy when the oil temp hits 225 & my Gene Berg oil temp sensor starts to flicker the oil light.

I'm not saying you should stick to a 1600, you should do what "you" want to do!

Anytime you can use new vs used go with new if you can afford it. Remember, Horsepower is measured in Cubic Dollars.

Give me a call when you can so I can explain my thoughts on doing what you want to do.

Marc,
Remember if you go with machine work and bigger piston/cylinders the wall thickness of the cylinders is less, therefore excessive heat can be even more of a problem. A good stock dual port 1600 with a small cam, dual carbs, 009 distributor and free flow exhaust will give you plenty of reliable power. A good full flow oil filter oil pump is also a very good investment. If you want more oil capacity go with the thin add-on sump for another 1 1/2 qts. of oil. The filter and sump will give you a total of 2 more qts. of oil. This will help keep the heat down and extend the life of the oil. The dual carbs don't have to be big. Remember the stock is a 34mm ventori. Dual 30s to 40s is plenty. You don't want too much fuel because it can thin your oil. Pm me if you want my number. I have built plenty of these motors with great success.
Good luck,
Bob

Thanks, good advice & confirms my research so far. I am going to go for 90.5 pistons & jug set though which will give me a 1776. Along with a new AS41 case machined by Rimco.

           1776 are my favorite engines... good enough power &speed, very good reliability, able to use stock carb (if money is tight) but need to use a larger jet...very very simple switch....
