1390 Top end set-up
I have this set-up that was built for my other EFI boat, but honestly I really dont have enough time to ride 2 boats, so I have decided to sell it. This top end has never been run, all fresh machine work.
This is a pretty radical 1390 top end. Started out as 66V cylinders, bored and nicasiled my Millenium Technologies. Then they went over to Tim Judge for porting. Me and TJ based this porting off the specs we have been using on my EFI 1300s. Bases have been cut and all cyl heights are correct. Riva 66V heads machined for 87mm, and combustion chambers cc'd by Lowel Horning. Then the cylinders and heads went to Polydyn for coating. Cylinder exhaust ports and head combustion chambers have been ceramic coated for high heat.
Set-up comes as pictured
(4) TJ ported 1390 cylinders w/ceramic coated exhaust ports
(3) Riva heads machined for 1390 w/ceramic coated combustion chambers
(4) Exhaust valve gillotines cut for each cylinder exh port
(3) Speedwerks gas valve bases
-green bellows, top caps, red springs, and all hardware to install gas valves
$2000.00 Shipped in the lower 48.
overseas shipping available.
pm me or email firstname.lastname@example.org
Will work with EFI or carbureted.
I will help with jetting specs for carbureted.
For EFI application, I also have an updated fuel system for sale that consists of a Danny's billet fuel rail, in tank fuel pressure regulator block-off, and parts numbers and specs for external fuel pressure regulator and TPS voltage. I have photos that can help you thru the fuel system modification.
