Stroking Chocco's Cross 8 - Fuel Economy Question ??????

[IJ.]

Reckon the missus would notice if I swapped motors with the SSV

Not if we don't tell her

Can send her off with mine shopping or something ....

Agree with you, my L76 with baby cam could achieve 600nm & 278rwkw @ full noise. That's with the great flowing L92 cylinder heads that the 5.7 doesn't have!

Don't need L92 heads to do that. A good cathedral will make far more than that. I've seen 780nm off hand ported 853 heads and a 216/226 cam ;-)

No worries but what RPM?? Certainly not between 2500-3000 as the Op requires!

L92 heads are too big for the 6 litre just sayin.....

how much do you think the stroker setup will cost you? I'm thinking at least $6-7 K. probably more

Cost of parts $4000, but I have found some dyno figures of the comp cam 220 on a standard ls1 with headers and exhaust and otr.

Would be a good compromise, shld get most of the torque were I want it.

[bush_basha]

what about balancing and machining, is your pricing including new bolts, bearings and fluids etc.

[chocco]

i am going to eat humble pie

After spending frickin hours googling last night looking for dyno runs with LS1 cams I found the comp cams 220 from Oztrack which I believe is similar to Oztracks FE cam couldn't find any real dyno figures for the FE cam only simulated figures. Trying to find the dyno runs to quantify what you are after is bloody hard.

While it won't move the torque like a stroker going by the torque figures it should do almost what I am after at a cheaper price.

[brenten88]

oztrack also has the adventra/cross8 camshaft which is slighlty better with torque again over the FE camshaft pritty much the same though

if you want true torque you need to add cubes plus a small camshaft with a tight lobe seperation for example something like a 212/218 or there about on a 108-110 LSA will be extremely torque would make peak power at about 5000rpm and would pull like a train off idle and would probably still make 250+ awkw to boot

Look at the truck cams for the 5.3/5.7 the 206/212 in the yank forums for consistent torque over 400 ft/lbs 550nm at your rpm .

It's actually perked my interest in getting cammed , group buy for the 206/212 , lol

Sent Choc specs for a USA "RV Cam" last night

So are you saying I should have known this or that great minds ........ RV Cam, Caravan Cam or CCC , Chocco's Caravan Cam, lol

Would say "Great Minds" but we both know that's not quite right

[XUV]

a few dyno graphs here http://www.ls1truck.com/forums/dynod...o-numbers.html

I am going to try and chase up some dyno figure pictures for that "CCC" cam this weekend while at the same time trying to learn more about what all the cam figures mean.

IJ suggested I post a pic of the carvavan to put it into perspective, the car and the van are over 40ft together, VAN GVM 2490kg + Cross 8, Its not the most aerodynamic setup !!!!
