B2 Motorsports - Cliff Rosson All-Aluminum 331 SBF Build

Jac, if you use a standard base circle cam, there is sufficient clearance. The tightest spot is on the #5 cylinder as you say, but with a big base cam, it's fine. I never take anything for granted though...I checked any way....hahaha

Rick, I really don't see the need in it. For all of my Fords, they get Ford Racing double roller timing sets. IMO, you would never see the difference in anything else. If I need something more "hipo", or if I need something I can adjust almost on the fly, I'll use a Jesel belt drive.

The regular Ford Racing double rollers are about $100, have a buttload of keyways, and come with a thrust plate. Can't beat 'em.

Crank is en route back to KY. I had them balance it too.

Are you serious 69lbs?
That's pretty light... What's it made out of unobtainium?

Congrats.

Got to run my '03 again at Portland yesterday. We put some Wilwood 6 pistons on the front of it after the first tioe we ran it and went right thru the pads that came with them. I called Wilwood and They had me purchase Polymatrix E - great combination plenty of initial bite and great modulation.

We started running 4 of the tight corners in 2nd gear instead of 3rd and it was moocho faster with gobs of torque coming out. I'd go in with lots of brake, heel and toe (T56), and stand on the brakes with the side of my foot to the turn in point. Once we got the braking and shift points figured out it worked very well - I may have missed one shift for the day. Almost spun it at 12 from shifting too late (late braking), but got out of it and sheepishly drove away.

Ran down a couple of 911 looking things in the last session, one being a Turbo. Overheated the blower cooling system and ran out of fuel nearly simultaneously and had to pull off early. I don't think the air conditioning compressor was happy with it either.

Sent a couple of young guy's out with it today and they were running 110 (2nd and 3rd) and all was good.

The 03 Cobras are neat cars - I need to retire mine.

Brent - a cool 430 will make a great FIA for me.

I hope the internals on that T5 aren't stock. Even a T5Z won't hold up long to the power that 331 is going to make. Ask me how I know. I'm pushing 425 out of mine and I've gone thru several of them, thankfully I know how to rebuild them too. Stepped it up to a TKO series and no more breakage.

Brent does A1# transmissions also, able to handle whatever you want to throw at it, for a price of course, but your getting the best from the best...

They are not - breaking it is still a very real possibility.

Alright Cliff....

Got pretty far today. Had to beat the poop out of the oil pan and open up almost every single hole on the flange to get it to fit. I like Aviaid pans, but I've never had one go on without a fight.

Timing cover and balancer are on. Checked the timing marks against true TDC and found out that your adjustable pointer won't adjust to where we need it. I ordered a new one, and will throw this one in your pile.

Measured for pushrods and called Trend to get those ordered. They are a completely custom length, so it will probably be the end of next week before I get them. I wait to put the intake on until I get the pushrods installed and make sure that everything oils the way it's supposed to oil. If I have to make an adjustment on something, it's a lot easier to see what's going on with the intake off. Easier to check lifter preload that way too.

All-in-all, not much more to go. New timing pointer will go on, I'll check the balancer again, then the water pump will go on. Pushrods will come in, I'll throw the rockers on, pop the intake on, and that will pretty much be it.

Brent-is that a 1-piece reusable pan gasket? If so, a FelPro?
Nicely done intake ports for a 331.

[ERA2076]

Damn Brent - Just Awesome. I am very excited to have it. I ran my 03 at PIR this morning in the rain and was very fast compared to the others in my group.

Dancing a 3500 pound car on wet asphalt gives me some hope I can a manage this.

OTH - driving a 90 inch, 2300 lb car, with more horsepower than my 3500lb car is some cause for concern.

Beautiful work.

[blykins]

Yes, Felpro one piece gasket.

On the head intake port, that's how it comes with a CNC cut Twisted Wedge head, made to fit a Felpro 1262 gasket.

I mocked up the Victor intake yesterday to check port alignment and it looked great. The port openings on the intake were just a little smaller than the gasket size, which is just fine as it will help with velocity on this smaller engine.

Cliff, that's why cars have gas pedals. You can control them easier that way.

[ERA2076]

Yea - I am counting on extreme response - think we have it?

[blykins]

Should be pretty crisp....

[ERA Chas]

Brent,
Mind posted an all-up weight when done? Carb, coil and wires-no alt. I'm guessing under 420.
Will Cliff run that System-1 or that just for dyno?

[blykins]

I don't have any scales to measure a complete engine with. It's extremely light though....I could pick the block up off the floor with one finger. The crank weighed 46 lbs.

The oil filter is mine. I use it on every engine when I dyno.

[ERA Chas]

That might not hurt a bathroom scale.../:<) Probably 380.
