How are the ARE 360s doing?
He'll post up with numbers when he starts goofing off at work on Monday. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
ARE told me not to expect a lot - It's just a 4% increase in displacement; so I went with the standard short block

Which would be better, all bore or stroked? I have some new things to research <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
I am running ~122-123mph with my ARE 360, S1 heads and 226/234 cam on 112LSA.
MAC headers, bolt-ons, cutout, stock clutch etc etc.
I love my 360. No coolant leaks or dropped sleeves, lots of power and torque. (404/400)
If I were to do it all over again I would have went iron block 427.
4.060 bore x 4.125 stroke = 427ci and lots of fun.
11.5:1 comp, S3 LS1 heads, LS6 intake and ~480-500RWHP for a great price.
Taking out the extra 75 pounds the block weighs would be very easy and you would never have to worry about dropped sleeves or coolant gobbling issues.

<strong>If you are going to spend that kind of money.. Why not go to a 382 All Bore? The shortblock is around 4 to 5k..</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Unfortunally, the short block is $6200 from MTI. I called.
Chris, what are your dyno #s/mods? It looks like I may go the 360 route. Its the only feasible way to go for me at the moment. The 382 seems nice, but still the power to $$$ isnt there either. It puts out ~ the same HP as stock and the 360.
Decisions.. decisions...
Mac headers with offroad
ARE 360 shortblock
ARE S1 5.3 truck heads
226/234 112LSA .560/.560 comp cam
3 inch cutout in in pipe
Dynomax ultraflow muffler
17 inch enkies
12 bolt with 4.11
stock clutch for now
404RWHP@6300rpm and 400RWTQ (400 RWHP from 5400-6700rpm)
Best ET (traction limited): 11.7
Best mph: 122.60mph
Best sixty 1.78
DA for those runs was ~900 and I had the A4.
With the M6 and with electrical problems (battery tipping over on launch against the strut tower)
I ran a 12.0@120.7mph with a 1.89 sixty and off idle launch in 2300-2500DA.
Curbweight: ~3400 pounds when I ran the above times
Heads flow 298 cfm at .600 lift intake and 227cfm @.600 exhaust with no stack or pipe.
With a cam change to a 230/230 112LSA XE-R grind I would pick up about 8-12RWHP peak over my current comp cam. (Not sure if it is worth it to me for .1 and possibly 1mph)
I am very happy with my car and its times. With the rev lok clutch, HD DS, adj Master I should be able to hook to a 1.5 sixty and 11.3-11.5@122-124mph in good DA.
That is fast no matter how you look at it. Dynos for me are a reference for tuning only.
Hope this helps,
Chris
ps- you can also get a forged stock shortblock as well from ARE.

The 360 is GREAT for nitrous or boost as well as a great NA motor. Peak numbers arent going to be all that different but torque and HP comes in lower and is nice broad and fat <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
See sig for updated times. This was in 750 DA with 3425 curbweight and spinning through all of first gear.

I get 356 cid when crunch that in Desktop Dyno. Is Desktop wrong?
Seems like a Big Bore with an offset ground crank would be the ticket.
4.1 bore and a 3.72 stroke works out to about 393 cid in Desktop Dyno. Is that right?
I thought a 4.1 bore and 3.72 stroke would be about 396 or 397 or so.
