I like the torque curve looks like it's has at least 300 lbs @ 2k so basically when your converter flashes you'll have at least 300lbs , itwill be super fun in something with 3.73 and about a 26" tires

Camshaft SP350/357 12677151
http://www.crateenginedepot.com/Camshaft-SP350357-12677151-P51840.aspx


19367080-The longblock only for $4250 list or $3300 from Crate Engine Depot.
http://www.crateenginedepot.com/Chevrolet-Performance-SP350357-Base-Kit-19367080-P51858.aspx


19367082 is the Deluxe engine set, with 600cfm Holley carb(included but not installed), Vortec dual plane intake, balancer, fuel pump, flexplate. GM list is $5375 down to $4350 from Crate Engine Depot
http://www.crateenginedepot.com/Chevrolet-Performance-SP350357-Crate-Engine-Deluxe-Kit-19367082-P51859.aspx


19367084 357hp/350 Turnkey kit $6,875 GM list from Crate Engine Depot for $5550.
http://www.crateenginedepot.com/Chev...84-P51888.aspx


Same parts as 19367082(as far as I understand it) plus many more and this engine is completely assembled from GM. You must supply the fuel line from the fuel pump to the carburetor.
Those GM front accessory drives are NOT inexpensive parts to buy from GM.

"Our SP350/357 Turn-Key package comes complete with the distributor, carburetor and balancer installed. The starter, fuel pump air conditioning pump, alternator, front-end accessory drive kit and more are also included, ready to bolt on."

Right now Summit has the p/n-283-2 bolt and the 283-4 bolt L31 crate engines for the SAME price US$2069/CAN$2787. Usually the 4 bolt main 283 engine is from $40-$100 more for the 4 bolt main retention on main bearings #2,#3 and #4. The L31 replacements come with a balancer but no flexplate, also comes with 4x reluctor ring behind the balancer under the front timing cover.
You really need to shop these part numbers around as well. Often you can get free shipping like I saw at Summit. Don't forget about some of the vendors requiring core charges.

1996-2002 L31 2 bolt mains 12530282 US$2069/CAN$2787
1996-2002 L31 4 bolt mains(mains #2,3,4 only) 12530283 US$2069/CAN$2787

Summit isn't accepting either engine p/n 19367080, 19367082, 19367084 or the cam part numbers 12677151 for the new 357/350 crate engine. Shouldn't be too much longer if you are a Summit Racing user.

So Fast ordered the 357hp/350 roller cam 215º/223º. When it arrived, it was NOT in a typical cardboard tube that GM normally sends its camshafts in. It appeared as though it was dropped the pavement as it was damaged on one of the bearing surfaces. Shipped it back, will advise once the new one comes.

When I last received a GM LT4 Hotcam 218º/228º it came in a nice durable tube type container.

Are you guys still getting GM cams in this style shipping tube?

Thanks in Advance.

They don't say if it's with 1.5 or 1.6 rockers

The description for the long block specifies a 1.5 rocker ratio.
