Re: Odd Problem

If the bolts are stainless replace them with 8 point header bolts made by arp and see if they break, stainless bolts dont take vibration well Good advice here. We tried SS on our racecars and didn't have much luck. ARP bolts and checking them often fixed all the issues. Drilling them and safety wir...

Re: 406 rear main bearing issues

line boring doesn't change the distance ofk just adds more bearing material sounds l;ike so true does it have any harmonic vibrations Line boring actually does slightly raise the crank in the block. They sell timing chains engineered just for this reason. http://www.summitracing.com/parts/clo-9-310...

Just an FYI. I have a lots of experience with those Eagle rods. They are decent piece for the money. The rod bolt are very durable but need to be stretched multiple times before final assembly torquing and must use the ARP lube.

Is there a ground strap from rigging to engine and one from battery to rigging? Sounds like a lack of grounding to me.

Re: Expansion tank

Post a pic or link to part and that will help clarify. But most likely if boat runs cool now and you add a different expansion tank,as long as system can burp air out you will be ok.

Re: Radiator (Pipe Welding)

Just my opinion but I thought about it during my build and instead of 4 hose clamps you will now have 8 to worry about. It would probably never happen but chances are increased slightly. Food for thought that's all. http://www.summitracing.com/parts/sme-240175 Never worry about a hose clamp again.

Re: Need info on gearbox ASAP.

They are decent boxes. A little loud off idle so don't be scared after you first run it. Guy that builds them is out of Oviedo. He can prob check it out. At 76" long max a 3 blade R would prob be fine if it makes over 300hp. I had one with a 2 blade @ 79" and about 290hp. Worked good.

Re: If you had to do it over again boat build

What is max diameter prop you can run? I would stay with a narrow blade prop. Less torque roll on that short boat. Depending on length you can run a 5 or 6 blade Saber/Razor would run good.

That's a deal and a good combo for your 400. Lots of torque there most likely.

Re: Material for 4 cyl motor stand

Who's gonna weld it? What process will be used? I would recommend DOM tubing as your first choice and conduit as a second. Both are easy to work with (cut/bend) and much easier to weld. Stainless is a great material but is harder to cut,work and drill. Also takes much more skill and more specific we...

Re: 383 timing

Post some close up pics of heads and intake. Someone here will have used them. 32* is a good starting point. It is safe and the engine will run well. All depends on cylinder head design. Older conventional combustion chambers generally like up to 36* of timing to run optimally while newer fast burn ...

Re: Loud

More ratio and more prop. Slow tip speed and lots of pitch is the key to quieting the that part of the equation. 2.68 and some NGR's set at about 5200 WOT would be quiet. Then some large automotive mufflers, non flowmaster style. You want something that is actually designed to really quiet the engin...
