Well Marine Assault Custom engines will be the OEM supplier to Trident Custom Boats. Engines for their new "Revolution" dual jet drive deck boat.
Trident Boats Web Site (http://www.tridentboats.com/)
522 CID was decided on for a number of reasons. To operate within the effeciency range of a single intercooled 3.3 Whipple, to allow use of GM Gen VI blocks and cranks and also use of Edelbrock Performer RPM Marine cylinder heads. Everything working together.
Some of the components, J&E's best blower piston, Eagle "H" beams with L-19 bolts, Comp pro magnum rockers, Isky springs, hydraulic roller lifters and push rods, Cometic
head gaskets, ATI super damper blower balancer, SFI flex plate etc.

This OEM engine will be as revolutionary as the boat. Design, construction and features etc. Every component has been selected to compliment the other. This results in an awesome "engine combination". The entire engine combination designed specifically for the boat as well. Who could ask more of their OEM engine? This will not be a crate engine or a "select this model" engine from a list of take it or leave it models.
"Froggystyle" from Trident requested between 650 and 700 HP as the base model OEM engine. The engine will actually be built for 900+ HP. This will allow a HP upgrade without being concerned with the engine's ability to handle it. Pistons, rods, head gaskets, cylinder heads, camshaft etc. will all be there if more power is wanted when the warranty period is up. Or up front with no warranty.Disclaimer Will have to speak with Trident for details. A blower pulley change and computer re-program and a few hundred additional HP is there.
The Edelbrock Marine heads are not necessairily the best flowing or the most HP producing heads but: they work perfectly with the CID engine being used, are heat treated, hard anodized, thick decks for blower use and have severe duty intake valves and Inconnel exhaust valves.

Here is the new Gen VI block.
Has been to the machine shop and bored/honed to 4.560" This big bore will unshroud the valves a bit and add a few cubes. Had to get it bored and bring it back to the shop to check deck height. Will send it back for decking and final cam bearings etc.

Getting ready to check the deck height.
Already know the final bore size that will be needed for each engine once the production run starts full blast. Need to establish an exact deck height now. This will allow me to tell the machinist that I want "X" finished bore size and "X" deck height for each engine. Not have to mock up every one of them. Take my time on this one to establish the dimensions.
Will temp install the crank and a piston/rod assembly in all 4 corners.
These are the lucky components.

#1 piston installed. No rings.

Use the dial indicator to make sure it is exact TDC. #7 in work here. Did this to all 4 corners. At least 3 times each.
Use the depth micrometer to measure exactly how far the piston is in the hole. Easy to square the piston in the bore since no rings are installed.
Odd side measured .0265" and the even side measured .024"
Will deck both sides so the pistons are .005" in the hole. Custom thickness gaskets will give a "quench clearance" of .040". Future servicing of the block and it is squared to deck height of .000". a standard .040" gasket will maintain the proper quench clearance.

These Isky 9000 series cryo treated springs are the best available. Using titanium retainers to help them retain as much service life as possible. Also these hardened spring seats will not let the springs "work" into shims or soft aluminum. These hydraulic roller lifters are the latest in technology. They allow up to 160# seat pressures and way over 6K RPM's

One more view of cylinder head and springs etc. Make you turn your head?

Froggystyle do not look
Yes this is a v-drive timing cover on your engine being used as a template. Going to drill the block so it will accept a gen V or Gen VI timing cover. They use the same oil pan but different timing covers. Gen VI cover does not allow a double roller timing set without a spacer. Use a GEN V and be done with it.
Ok Froggy, maybe you should know to order Gen V timing cover and Gen VI oil pan.

More later.
Info,
Rollmaster make a timing set that is a true roller and will fit under the the stock cover if that helps.
