Prop? 272 LS 86 SBC Alpha
 

Simple setup 350/260's all stock going to throw thru hull thats about it. So what prop?
-Mike

Not sure if it helps you out, but I ran 21's on my Nova when I had stock 260's.

I run 23 Mirages and labbed 25 mirages on my 242 with twins they are warmed over a bit but turned 23's stock with 260horse.

But I would say 21 mirages or 19 mirage plus

I had an Idea on 21's also thanks
-Mike

I think we ran 23 Mirages on our 27' Formula way back when. It also had twin small-blocks.

Assume they are counter rotating drives?
-Mike

Yes, counter rotating Alphas.

I am running 23's on my 242 with twins. I am thinking about moving up to 25's but not sure just yet.
