And it won't have to pull skiers more of a vintage PWC

At WOT & over 6000 rpm I'd say you need a single plane intake & a 750 /850 carb. but part throttle suffers. s/b chevys will turn over 10,000 in full race clothes.

Thats the kinda input I was lookin for,I'm wondering about the extra stroke on the 400,and where that will move peak mph since peak torque is a bit lower than say a 350 or 351 and also can you spin a bra$$ prop safely
to those kind of rpm's.In the mid 80's I had a
little sanger flattie which wouldn't pull the only gears i had for the old v drive,they were 18% over drive it just bogged along with a little dinky 12x12 2 blade prop that came with.

So one day I get an idea,I flip the gears over in the v drive,now I got rpm's and Start playing with the a$$ortment of props I've gathered over the years and I end up about the same as early CC with a 13x14 super cup could have used a bit more pitch but didn't have the bucks back then.It would run almost to 65 mph(Nordskog speedo) into a light wind chop at 6800 rpm this thru a velvet drive so had to be some loss I think there.(how much ya think Eric)

Well amyway this new toy has numbers running around in my head probably will till it warms up enuf to play with thanks Riedp,79 ,Eric,Dog for the input.

79, good motavater,got my best heads off my 64
pickup today replaced them with some stockers I had.Early 202 fuelie heads,ported both sides,
Triple springs,pinned studs.I'm gonna match them to an extra set of nicson manifolds I have.Good point on the heads.Think I'll try to design for 6,500 and try to prop it between 6 and 6.5.

Thanks Munday
