First of all Chevy did not make a vortec engine in 1987 or 1995, those engines are TBI / Throttle body injection engines. And yes they will interchange with no problems.
Yes they are.
On the Vortec the computer does it all.
2.4l engines are basically the same. There may be slight changes over different years like sensor changes or mounting brackets.
1988 to 1995 are the same engines. They will all be a direct bolt in.
The firing order for the Chevy 4.3 is 165432. This order is the same for all of the Chevy 4.2 engines regardless of year.
NO, Not even close to being the same design. In late 1999 Chevy REDESIGNED all the transmissions and engines.
Above 60 psi if it is a CPFI= Central Port Fuel Injection. wish I am sure it is, all Vortec engines have this CPFI.
1996 was the first year that all GM trucks went to Vortec engines - it IS a Vortec...
what should be my gap on a sparkplug for a Chevy vortec 5.7 350? Some set them at .060, but I set mine at .055 as they get older they will burn down to .060 but anywhere in that range just put them all the same gap
NO. In 2000 chevy redesigned all the bodys,engines,transmissions and frames.
YOU CAN'T. It is NOT ADJUSTABLE. The idle is all computer controled.
