I was wondering if you guys could help me out with my 2002 L31 swap out of a chevy express
It has 100,000 miles on it.
I am putting it in a 2003 awd astro van 2" lift, that I use for surf fishing up here in rhode island (putting that motor in is quite a feat in itself for me, but within my capabilities!!)
I want to do the smart things before I install it,I am going to go with electric fans, http://www.ebay.com/itm/CHEVY-ASTRO-SAF ... 5w&vxp=mtr
thinking about an EFI intake upgrade
Radiator http://www.jegs.com/i/Champion-Cooling- ... 6/10002/-1
oil cooler not sourced yet
can the fuel injection be improved upon, I would like to keep it.. Not racing it just want responsive driving on the high way and sand.
any input is welcome.
I don't mind spending some money but don't want to do things that are not nesc for my application
cold air intake also?
water pump
timing chain
oil pump?
Cam ( mild and which one?)
what head work is required on the vortec heads if I do a cam?
valve covers?
I have the motor Mounts and I have cast iron exhaust manifolds that work for this application, courtesy of Captin Crunch
Should I put new pistons in and should I do any head work on the vortec heads if I leave the cam that is in it now?
crank polish and bearings?
Hone cylinders or bore 30 over? (is that a good number to bore over?)
I am going to have the machine work done and probably lower end, pistons, heads, EFI intake assembled by the same shop if I go that far into it.
I can wrench but have limited abilities.
Thanks
