Latest Flathead Project.......

[5 Horse Fan]

After going over the checklist, I seemed to have about 95% of the parts to build this engine.

Heavy Duty 4.475" Billet Rod, Wiseco Piston, Walbro WB Carburetor, Single Bearing Aluminum Bore Engine.

Assorted Parts, alot of which I found in storage.:smile:

Every single part of this engine is new or nos.:thumbsup:

damn looks like it will be a fast one!!

 

[5 Horse Fan]

The carburetor venturi is about .975" and may be too much for it.
Won't really know till it's running.
I don't plan on spinning it past 6500 rpms for now.

 

[Minibike187]

nice! u running gas? how much hp est?

 

[5 Horse Fan]

I'll be running gas and I would think it would be making 7 maybe 8 HP.
It's such an unusual combination of parts, it's hard to say what it will do.

 

[Minibike187]

ahh mix and match special? lol sounds like its gunna have some kick to it!

 

[5 Horse Fan]

Not the best way to build an engine but yeah....
Spare parts and Clearance Items.

 

[Minibike187]

what ever works to make hp!! nothing wrong clearance!!

Is it a stock bore? Where did you find a chromed wiseco piston? and what cam are you using.

Stock Bore and I found the Piston on Ebay.
Cam is a factory I/C cam, which is said to help make a little more torque.

why have a stroker connecting rod but stock cam and stock crank... a bigger cam will compliment those parts greatly

 

[5 Horse Fan]

I have a .362" lift cam, but I think it's massive for a stock bore & stroke engine.
The big end of that rod is huge and required me to have to clearance the camshaft on the exhaust lobe and the area between the lobes. Not ready to go grinding away at my new performance cams. Might as well have a working template for later.


And why not add more performance later.....:hammer::grind::drinkup:

yeah that is big for a stock stroke engine ...adding performance now or later is up to the builder

Here's the new crankshaft I will be installing into this engine.
I sent it out to have a keyway & internal threads machined into the PTO shaft.
Now it's ready for use. :smile:

 

[Minibike187]

nice!! how come u had it threaded?

 

[5 Horse Fan]

nice!! how come u had it threaded?

When I got the crankshaft it had those external threads and no keyway.
It was made for a water pump attachment.

 

[Minibike187]

ahh :doah:
