454? On DB hull

Post by eazy89 » Tue Mar 15, 2016 7:51 pm

Looking to do an economical build. How you think a 400hp 454 on 14x8 DB hull with a 2.38 and 2 blade R will run? I seen a similar boat that ran damn good but wasn't sure of the HP. Any input

I think a 3 blade R would be better suited to push that boat with a big block.

That's basically my boat,it'll run damn good!! But you'll need atleast a 3 blade,2 won't do it if it's 500hp

Nothing wrong with a BB. It needs to be built to produce the power its capable of. Stock form an LS would be a better choice with more power and less weight. On BB with a compression increase, head change, cam, intake, carb and headers 600 hp is pretty easy.

Yeah can't drop big money on a motor yet. So I was thinking ride it until the motor blows then upgrade. Anyone know if an LS motor will mount right up to the 454 stand?

U should be fine, I run a fully equipped 13.6 DB w a SBC and it does just fine at what I ask it to do. Just make sure you have a good valve train,good cam, and the right gearbox to prop ratio. Get the card on your cam and ask a pro

There is mounts for the LS that adapt it to BBC engine stands. Keep an eye on the oil pressure and tune and the 454 will live.

Like loud mouse said,there are mounts to put a ls motor on a BBC/sbc engine stand with out any modification. Depending on what year 454 your using it may save you some money. The newer gen 6 is a great plat form. The vortec heads are great heads for airboat and it's a factory roller motor. It's what I used. Crow hater did a real nice Wright up on here about a budget 496 build that make good power in the correct rpm range. Look it up even if you don't want to stroke it. But if you do decide to stoke the motor whites performance has a good deal on a nice rotating assembly.
And thanks john c for posting that pic!!

I run a 14x8 DB with high sides 383 stroker and a 3 blade NGR with 2.38 ox box. Ran dry with 4 people and a cooler last weekend.

That 454 will be just fine on that DB. Supply with good valve train components, keep the tuning modest and it will live just fine.
