Sorry, I should have added that. Strictly sand dune drags.

I'm not into dragging, or sand. but I hear that sand has great traction with good paddles. So w/ 100 hp i'd imagine go as long as they make, lol. I'd think like +8-+10

First of all what kind of motor are you running? 100hp is a very strong claim especially if you are running a stock cylinder motor.

I ended up going with the +8 swingarm. I'am running stock jugs with a full drag port, trinity head with 15cc domes, 34mm carbs,CPI out of frame drag pipes,wiesco crank and pistons. I was told roughly 100 hp. But I wanted to leave room to expand with the swingarm since everything is completely gutted and being restored. I'm hoping to have it done 4 weeks from now.

I hate to be the asshole but its not going to make a 100hp. Even on alcohol I would really question that. It can and has been done on alcohol but is unlikely. Maybe if it was like a 7 or 10mm stock cylinder stroker, but a 350 no. Damn good running 4mm strokers are in the low to mid 80's. One other thing most likely those domes are way too small, I assume they are prodesign. I dont know why they even sell them. 15cc domes are usually good for one thing, wearing out the pistons and cranks and everything rotating fast.

Thats no big deal I figured the engine wouldn't be up to 100 but I wanted to make sure the swingarm will be long enough when I do have 100hp down the line and not kill the power it is making now. I have a trinity head with 17cc domes also.

Put the 17cc domes in it. There is a new rather large thread on this subject written on planetsand. It was started by kelsey at RK tech. RK makes some of the best heads out there, you should take a look at the article there is a ton of good information in it.
