Starting on a SB2.2 engine build

ask Jones
you can get a bigger wheel with the .937 but mike can tell you if it's worth it

Yes he was the one that recommended either a .904 bushing that he sells or a Jesel .937 keyway (expensive) & a 50mm or 55mm cam journal.
decisions, decisions...

What size is you main journals? I'm currently building an sb2.2 myself and am looking for part numbers on specific bearings. anyone care to help a feller out pm me or something. I'm using 2.300 main and 1.850 rod journals both .010 under

2.648 mains, with a 2.10 rod journal, this is going to be a 9.325 deck 454ci.

Is it best to go with the longest rod possible?
I was thinking 4.185 bore, 4.125 stroke, 6.25 rod, 1.0 CH piston.

Going with a Jesel .905 dog bone lifter with a .820 wheel set-up & a 50mm roller bearing cam journal.

[wyrmrider]

why the small wheel?
is that as big as you can go with 50mm
ASK YOUR CAMGRINDER
#2 longer is better- looks good
longer rod changes cam

Jesel dog bone lifters with a .905 offer only 2 wheel diameters .820 & .785
& a 50mm will keep more oil away from the cam than 60mm Babbitt bearings.
2 engine builders & 1 cam grinder said that will work & be plenty big for what I am doing.

The 1.850 rod journal is a Nascar or IRL diameter. They are not available, at least from Clevite- you need to check other sources- in a .010 undersize bearing. They require either a 2.008 or 1.976 rod big end bore. The rods you were looking at designed for a 2.1 rod journal will not work. There is a Nascar rod journal in the 1.77 range (don't remember exact dimension) for which bearing are available. You will need rods that have the proper bore for the bearing/journal. they may be available as Nascar take outs but the ones for 2.1 journal aren't it.

I have used LSM rollers in a .937 diameter with .850 roller. Dimensionally the same as the Jesels. I did not find they lasted as well roller failures and bearing wear. The Jesels are more expensive but can be rebuilt. I used a 55mm cam core which was OK The Valve train was all Jesel with titanium valves. Springs PAX 1329 and 1326 (400 seat, 1000open approx.) 9500-9800 in a LSR car. Rpm needed to make the power I wanted. Nothing lasted quite as long as I thought it should so I was behind the replace the parts curve. Your 1000 mile replace the valve train with mostly easy street miles might do it.

Ran all the numbers through my PipeMax software & came up with 1113h.p.
If everything is perfect on the build & dyno I think it should be close to this.

[69434]

Opps fat fingered the h.p. number on my PipeMax software
It should be more like 1013h.p. if the VE is 110%

Does the SB2.2 head have the same firing order as a LS head?

It's whatever the cam is designed for, mine is 18436572 like a standard SBC.

[69434]

Comp Cams said if they did my cam it would be an LS firing order.
I guess the firing order can be what ever you want it to be?

[wyrmrider]

UH NO
you are limited to crank layout and two crank revs per spark
