Boss 302 rod 4.6 shortblock - 2003-04 Mach 1 Registry Owners Club

Ben99GT · 02-27-2013, 12:23 PM

A short block we put together yesterday. Figured some might be interested since the 2012-2013 Boss 302 connecting rod has come up in discussion in the past.

Basics:
-2005 WAP block
-John Tymensky-spec standard bore Diamond pistons with a slight dome, stainless rings, H13 tool steel pins
-Boss 302 rods and rod bolts
-03/04 Cobra crank
-Tri-metal main and rod bearings
-ARP main studs
-3V windage tray

This one is eventually going to get a decent sized shot, so we'll give the Boss rods a little workout to see how they do.

Can't wait! Should post some shots of the teksid build too

Bmeagher · 02-27-2013, 02:48 PM

What's the part number for the windage tray?

na svt · 02-27-2013, 03:55 PM

I can't tell you how many people have been buying these rods. I hope Ford doesn't see there's some money to be made and increase their price.

Bmeagher · 02-27-2013, 04:15 PM

I just checked availability, zero in US and Canada

Not in the market but what kinda price we talking here?

SuperMach1 · 02-27-2013, 11:39 PM

whats the part # on the boss rods?

Sburns04 · 02-28-2013, 02:49 AM

yeah and how much power are these rods good for?

Ben99GT · 02-28-2013, 11:51 AM

I've personally seen Boss rods hold 680 rwhp and 8,000 rpm with repeated street and track thrashings without issue. Even the non-Boss rods seem to live OK at 600+ rwhp and 7000-7500 rpm. So I'm not sure what the "safe point" on the Boss's really is.

I think if you plan on breaking 600-650 rwhp, spend the extra $$ on a Manley just to play it safe.

Maximum Velocity here in SA. have a Boss with Kenne Bell's mammoth blower making 800hp with no problem. So im guessing they should hold up. I just ordered a set from tousley.

Yeah, but Manley only "rates" their H-beams for 750 HP even though they've held over 1000 rwhp. At 800+ RWHP I'd definitely go with a Manley (or better yet an Oliver) instead of a Boss.

wldtang · 02-28-2013, 08:41 PM

They were on back order. I got a brand new set in the box if anyone is interested.

I hear ya. Ill be happy with 650 when I done with my build. Keep us posted...

ModularMach1 · 03-01-2013, 07:49 PM

So is the boss rod the same length as our stockers?

Yep

Bmeagher · 03-09-2013, 09:26 PM

Kinda bring is back from the dead a bit. But if I was gonna do the 3v windage tray on my Mach....do I need to add any studs? Are the studs already there?

na svt · 03-09-2013, 09:53 PM

Studs or 3v main bolts

lcaptmorg · 03-10-2013, 03:33 PM

whats the CR with those piston? how much dome?

na svt · 03-10-2013, 04:33 PM

Ben, is this for your car?

Ben99GT · 03-10-2013, 04:54 PM

You have to get 3V ARP studs to have the stud extensions on the front 4 main caps which are necessary for the full length try. Coyote oil pan gasket might be an easier solution.

Compression is 11.5:1 with stock chamber volume.

This motor is for a buddy, I'm doing something a little different. Going with boost.

Bmeagher · 04-08-2013, 02:11 PM

What else is needed to run boss rods?

what would be needed to run the coyote gasket? at what rpm range will we start to see a benefit?

Bmeagher · 04-09-2013, 09:13 AM

I'd like to go big bore 3.7". So I'd imagine I'd have to use boss wrist pins?
