Scarab 29 with two Big Blocks?
 

Hi,
annyboady know a Scarab29 with two big blocks?
I know i need spezial headers ( small headers ) that it works with the tramsom cut out.
My questing, can the Scarab29 handel the wight from two big blocks?
I thing one engine is around 200-300 pounds heavier then a small block.
I plan to install two 496 Ho in my 1994er Scarab 29.
Does that works?
Thanks

you will never get them to fit it is to tight with small blocks in there to work on i could not imagine working on two big blocks in there center line of the drive needs to be at lease 34"

Beam on a 29 Scarab is 76.6in. I think the AVS and other Scarabs are wider. No room in the inn...

Hi,
thanks.
There is enouth room in the boat.
the problem ist that the drive center lines are to small.( like trc2 sayd)
I am planning to make a new tramsom on the boat , so i can make the cut out for the drives that it works.
Or i must build extremly small headers.
My question is because the wight.
Because the big block are a lot heavier then the 350 mag that was originally in the boat.
But how it looks like that was never done before.
Will see.
Thanks

I have seen a 29 with twin 502s squeezed in it in the past. It can be done. It is VERY tight though. Depending on how you put together your engines, you can come close to netting on on the weight, keeping in mind that the 350s had cast iron everything. Liberal use of lighter materials, heads, manifolds, exhaust, etc, could keep you close to even.

if you do redo the transom rise the x dim up 2.5 inches i did it on mine and wow did it make a huge difference in ride and handling and speed . you will have to go to a four blade prop though

why don't u build a couple of kick ass small blocks

I got a see this! As much of a fan of the 29 I never seen this over the years! Do tell...:worthless_without_p :drink:

trc2,,, how much speed did you gain and what power do you have ,,, single or twins?

Hi Humpster,
i own 2 496 HOs.
And i prefer standart engines.
I dont want blower engine in my boat.
I drive a 496 HO in my scarab 22 and it is a good powerfull engine.
I had no problems with that engine in the last 5 jears.

I will try to fit the 2 496 HO in my boat .
Maybe i make the X dimensino + 1 or 2 " 2,5 i think is a bit to high.
I need around 1 year for that project.
Will let you know how it works.
( with pics:) )

I didn't take any pic's of the install sorry guys I had twin small blocks in it boat rode and handle much better top speed was 74 to 76 running 4 blade 24's. could get more with prop tuning but ended up selling it

Why not do -3 imco boxes instead of redoing the transom?

Ring210, About the weight. 496 engines are around 170 lbs more each. That is 340 lbs more. You can build a light weight sun pad, use aluminum on the engine, etc to save weight. Move a few items (batteries) forward can also balance the boat.

Hi,
thanks,
thats my plan to do.
The original sun pad is verry heavie, i will change it in a light weight.
The early 496ho have aluminium exhaust. And the batteries comes in the cabin......
I think it works....
Will see it in the next time.
Thanks for our help.
