I thought you were working - you know on a 665 CID for some kind of boat ^^^^

I'm still trying to wake up........... sheesh.

What electronics you have picked out? With MSD or individual coils?

The electronics package should be interesting. Individual coils with individual cylinder knock control. We are looking at running per-cylinder widebands with closed loop control. Everything will be controlled by an MS3pro. http://www.ms3pro.com/


14 apache, how did you like how yours ran?

It's not everyday I get to play at this level. I've been collecting parts for a Marine 665 inch *naturally aspirated* BBC. That's 4.600" bore x 5.000" stroke. The Winberg billet crankshaft just showed up today :) I also have a photo of the Crower billet 7.325" long rods next to a stock length Manley rod for comparison. Custom RaceTec pistons, etc.

This is for John Mosetti's (BUP) 29' LaveyCraft NuEra that is currently being built. If you haven't seen the build on the boat, it's completely awesome. Follow this link: http://www.laveycraft.com/construction-of-29-nuera

I'm going to photo document the assembly of this engine as I go so you can see how I do it. That doesn't mean I'm right or wrong, it's just how I do it. I won't get going on this until after PRI sometime, but I thought I'd share the start of it.

The very first thing I did was pick out a block. I decided on a Dart Big-M pro. The reason for this was that I could get it in an 11.1" deck, it already came with 55mm cam bearing bores, .903" lifter bores, steel caps, and it has room for a 5" stroke with the spread pan rails and .600" raised camshaft position.

The next thing I did was to select a ring set. Why were rings #2 you ask? I needed to know the ring width and radial depth before I could order pistons. I also had to decide on a cylinder head so the correct valve angles, location, and spacing would be known. Once we figured out the rings (.043x.043x3mm in this case) I ordered the pistons. I am shooting for 9.5:1 compression or a tick more so I ordered the pistons with a 24cc dish figuring a 119cc combustion chamber. Once I knew the pin height on the pistons I could order the connecting rods. 11.1" deck - 1.27" pin - 2.5" (1/2 stroke) -.005" (piston to deck) = 7.325" rod.

After the block, rings, pistons, and rods were delivered and bearings were mocked up in the block, everything was checked dimensionally and weighed. The crankshaft was ordered to bob-weight . I would have ordered it to a finished pin size rods and mains but that was an extra 8 weeks (Winberg had a semi-finished 5" stroke partially finished) so I may have to play with bearing shells to get the clearance I want.

At the same time, the Brodix BB3XO-332 cnc oval port heads are at Chad Speier's (Speier Racing Heads) place getting worked over to meet the requirements that I have for this engine. That meant a camshaft had to be ordered so I knew the peak lift and then the valves, springs, retainers, locks, and locators were also ordered.

As you can see, one little decision affects the entire package. It's best to write it all down on paper before you ever order a single part.

14 apache, how did you like how yours ran?

They ran very strong in my boat with both the 351xo and the HH383mc put my boat to 110 trimmed loose. I see you are going to run 8o2 sensors is that going to be installed in water cooled headers or just dyno headers? Which kinsler intake are you going to use injectors above the butterfly's or below? 2.9" or 3" Butterfly's? Did you guys thing of running a belt drive fuel pump? I ran that on my set up and did not use a electric pump for starting.

BTW you are 900HP from yellow bullet?

8 O2's in custom waterjacket headers. We are using a Hilborn intake with 3" butterflies, injectors below the plate. Intake is identical to what was pictured, it will just be a different color.
We are going to be using a Weldon electric pump.
Yes, 900HP is my screen name on quite a few sites. My real name is Mark Dalquist, I own Throttle's Performance.

Not sure if around anymore. I remember BeenPerfected and a bunch of others using this with Solid Rollers and Dart Blocks.

I would be worried about cracking the headers with the o2 sensors in the pipes. The build is going to be cool. You have any idea how much torque it will make?

I'm using pressure fed lifters, there will be plenty of oil there ;)

I'm shooting for 900 ft/lbs........... we'll see. The o2's are going to be in the first inch or two of the primary tube and double welded. I've been told by the header builder it wont' be an issue. Stainless Headers is doing the work for us. We are also going to try and be the first waterjacket header that uses a true merge collector with a choke too. The headers should be way cool on this!

My engine made 4000rpm 785lb and peaked at 5200 840lb it was a 598. Think you will have no problem with 900lb
