1776cc or 1641?

1776 would be my choice. The 1641 typically uses cylinders that have very thin walls that can warp/overheat and score. 1776's, if built right, can easily outlast a stock type 1 motor.

If you really want that engine to go, both of them would benefit from a properly tuned dual carb set up. Center mount 2 barrel carbs are decent for off-road use, but still limit response.

Thanks Anthony you helped me out a lot now i just have to think of what dual carb set i need lol. thanks Brian

For a street 1776, you can choose between

- 2x 26 Weber idf

- 2x 40 Weber idf or 2x kadron (solex) 40mm (single throat), but we hardly see a properly jetted kit for such a displacement

Of course, you have to use good manifolds, matching the carbs!

Make the first one "36" instead of 26 :) (typo, I'm sure)

Jetting and synchronization are critical. Not the easiest things to do for a relative beginner (Who I assume the person asking help with these things is) but they make all the difference. Kads can be made to work with this engine, it's no big deal. The same adjustment procedures apply, as you'd run into with any carbs. NONE come "ready to run" for your engine, they ALL need to be jetted for just YOUR engine combination (And elevation)

Jetting is the cheapest way to get more hp on your engine. I do believe that if you put an engine on a dyno you can get more 10% of it. Usually the engines run rich on lows and lean on high rotations. You must have a set of main jets and air corrections. The little things are the ones that put the engine on the 100% and you can't get that by ear or by driving it.

in my opinion go Dellorto...( 40's are what i run ) if you dont mind tinkerin with your carbs once in awhile. they're like an old school Holley, you have to tune it more than others but when they're dialed in they scream!

if you dont wanna tinker then go webber 36 or 40s
